Equipment Description

The Groen Convection Combo™ consists of a stainless steel cooking chamber, an air heating

compartment with heat exchange tubes and dual fans, a steam generator, and a control compartment

housing electrical components.

All major components of the Convection Combo are encased in a 16 gauge stainless steel cabinet. Glass

fiber insulation, 1 to 2 inches (2 to 5 cm) thick, lines the cabinet.

The oven has a double door with two large, tempered glass windows in each door. Oven viewing lights

are mounted between the inner and outer doors. Separate hinges allow easy access to the space

between the doors for window cleaning and light fixture maintenance. A condensate collection tray at the

bottom diverts condensate to the oven drain. An optional solid door is available. The solid door does not

provide viewing lights.

All operator controls are on the front panel, with the exception of the pilot ignition switch and main gas

shutoff valve, which are located behind the sliding access door on the front side of the unit.

Standard controls permit the Convection Combo to operate in four modes:

1. As a convection oven

2. As a self-contained, pressureless steamer

3. As a combination oven-steamer

4. With or without the meat probe operating

Cooking chamber capacity:

28 Steam table pans (12 x 20 x 2-1/2"), or

20 Bake pans (18 x 26"), or

40 Gastronorm pans (1/1)

All units are supplied on stainless steel legs.

Controls and monitoring displays for cooking time, operating mode, and temperature occupy the control

panel. The upper portion of the panel has a digital time readout and touch pads for setting the time. Below

the timer section are lights to indicate the status of the unit plus touch pads that select the mode of

operation and switch on the power. A digital readout shows the chosen temperature, which is selected

with a dial. Status of the pilot burners is indicated by the lights above the pilot ignition switch, located

behind the sliding door in the front of the unit.

An insulated, gas fired steam generator is mounted next to the oven. Steam enters the cooking chamber

through two connecting tubes at the top and bottom on the right side of the cavity.

The deliming solution is poured through a port just below the front control panel of the unit. Our unique

automatic cleaning system transfers de-liming solution to the steam generator.

The air heating space, containing the heat exchanger tubes and fans, is separated from the cooking

chamber by removable left, right, top, and bottom partitions.

The compartment containing the automatic controls and other electrical components is on the right-hand

side of the unit and is entered by removing the right outside panel or by opening the hinged panel in the

front.

A drain is located in the removable bottom of the cooking chamber. Fluids drain from this removable

bottom and from the permanent floor to the stainless steel drain pipe outside the oven. This drain pipe

includes a spray condenser, which suppresses any steam escaping from the chamber. The drain

assembly includes a built in vent with overflow protection.

The roll-in loading and unloading equipment for Combo SuperSystem 40 consists of the Model CCS

"Smart Cart" and the separate Model CRS rack. When the rack is engaged with the cart, a hand crank

raises the rack for transportation and lowers the rack to position it in the oven. The cart is disengaged

from the rack and removed before the oven door is closed. Design of the system allows the rack to be

easily held in and transferred between reach-in or walk-in refrigerators and freezers, blast chillers, and

holding cabinets.

Water Conditioning

It is desirable to supply the steamer with water that will not form scale. Scale formation depends on the

hardness of the water and the hours of operation. In a few areas of the United States, the water supply is

sufficiently free of minerals to avoid scale formation. However, most water supplies carry heavy loads of

minerals, which will form scale and possibly cause premature failure of components.

Your local water utility can provide a statement on the scale forming qualities of the water supply. Water

supplied to the boiler should contain not more than 30 parts per million total dissolved solids (TDS) and

should have a pH of 7.0 or higher.

Please follow these simple precautions:

1. Do not rely on "water treaters" commonly sold as scale preventers and scale removers. They do not

work. The only proven way to prevent scale build-up is to feed in water practically free of scale-

forming minerals.

2. If your water supply carries scale-forming minerals, as most water supplies do, run the water through

a properly maintained softener. Exchangeable softener cartridges or a regeneratable softener can be

used. In either case, establish a regular program of exchanging the cartridges or regenerating the

softener. Installing a water meter on the inlet line between the softener and the steamer will give an

accurate check of water consumption and a way of determining when to change the cartridge or

regenerate the softener. By using a softener and operating within the softener's capacity to

exchange minerals, the user will optimize performance and minimize maintenance of the steamer.

3. If you notice a slowing of steam production, have your authorized Groen service representative

check the unit for build-up of scale. Heavy scale will reduce the unit's ability to boil water and can

cause a fire tube in the steam generator to overheat and burn out.

TO MINIMIZE SCALE PROBLEMS, USE AND PROPERLY MAINTAIN A SOFTENER, AND CLEAN THE

STEAMER PERIODICALLY OR AS NEEDED.

Installation

A. Mounting

When the combination oven is received, immediately inspect the unit thoroughly for external and internal

damage. Report any damage to the carrier.

Do not install a unit in these locations:

• Where the right side vents are blocked or within 2 inches (5

cm) of any

combustible material or within 12 inches (31

cm) of a heat source, like a

braising pan, deep fryer, char broiler, or kettle.

WARNING:

• To the left of any open-flame equipment.

• With less than 7 inches (18 cm) of clearance at the rear.

To avoid drainage problems, level the unit front-to-rear, or provide a slight pitch to the rear. Maintain a

minimum 8-1/2 inch (22 cm) clearance between the cabinet and the floor (Figure 2), to permit proper

operation of the cart.

WARNING: THE UNIT MUST BE INSTALLED BY

PERSONNEL QUALIFIED TO WORK

WITH ELECTRICITY AND PLUMBING.

IMPROPER INSTALLATION CAN

CAUSE INJURY TO PERSONNEL

AND/OR DAMAGE TO THE

EQUIPMENT. THE UNIT MUST BE

INSTALLED IN ACCORDANCE WITH

ALL APPLICABLE CODES.

The CC40-G combination oven is suitable for installation in

combustible and noncombustible locations. The flooring in

all installations must be of a noncombustible material. The

minimum clearances for Installations are:

Right side 2 inches (5 cm)

Left side 0 inches (0 cm)

Rear 7 inches (18 cm) Figure 2

CAUTION: The CC40-G combination oven

requires 24 inches (61 cm) clearance on the right side for proper service.

The unit must be installed in an adequately ventilated room with a provision for adequate air supply to the

unit. The unit must be completely installed under a ventilation hood, since flue products exit the appliance

over its entire depth. All items which may obstruct or restrict the flow of air for combustion and ventilation

must be removed. Do not obstruct the flue cover or any front, side, rear, or top vents after installation. The

area directly around the appliance must be cleared of all combustible material. The installation must

conform with local codes, or, in the absence of local codes, with the National Fuel Gas Code, ANSI

Z223.1-latest edition, including:

The appliance and its individual shutoff valve must be disconnected from the gas supply piping system

during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa). The

appliance must be isolated from the gas supply piping system by closing its individual manual shutoff

valve during any pressure testing of the gas supply piping system at test pressures equal to or less than

1/2 psig (3.45 kPa).

B. Gas Supply Connection

NOTICE: Making any electrical or mechanical change in the unit without prior approval from the Groen

Food Service Engineering Department may void all warranties.

Connection to the gas supply can be completed with 1" (2.5 cm) NPT pipe or approved equivalent.

Although the immediate connection to the appliance is 1" (2.5 cm) NPT, gas supply piping must be large

enough to provide 520,000 BTU/hr (152 kw) for each CC40-G. Supply pressure, measured at the back of

the oven, must be at least 6.5" W.C. [1.6 kPa] (maximum 14" W.C. [3.5 kPa]) for natural gas or at least

12" W.C. [3 kPa] (maximum 14" W.C. [3.5 kPa]) for LP gas. In Canada, the installation must conform to

the Canadian Gas Code, CAN 1-B149, Installation Codes for Gas Burning Appliances and Equipment,

and/or local codes.

After the unit has been connected to the gas supply, all gas joints must be checked for leaks. No flame

should be used when checking for leaks. A thick soap solution or other suitable leak detector should be

used.

C. Electrical Supply Connection

For the oven provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Local codes and/or the National Electrical

Code should be observed in accordance with ANSI/ NFPA 70-1987 (or latest edition). AN ELECTRICAL

GROUND IS REQUIRED. The electrical schematic is located in the service compartment and in this

manual. Maximum load per oven is 11 amps. In Canada, provide electrical service in accordance with the

Canadian Electrical Code, CSA C22.1 Part 1, and/or local codes.

D. Water Supply Connection

Two water connections are provided. One supplies water to the steam generator (treated water), and the other is for

the condensate spray (untreated water). A back siphonage device (check valve) must be installed in each incoming

cold water line according to local plumbing code. The water line pressure should be between 30 and 60 PSIG (210

and 410 kPa). A pressure regulator is required above 60 PSIG (410 kPa). Two 3/4 inch NH (garden hose type)

connectors are required to connect the water supply to the water inlet valves. The minimum diameter of each water

feed line is 1/2 inch (13 mm). Use a washer (or, if necessary, two washers) in the hose connection. Do not allow the

connection to have any leak, regardless of how small.

E. Drain Connection

A hose may be attached to the outlet of the drain by means of a clamp. Use 3" (7.6 cm) ID hose for CC40-G.

The hose may be connected directly to an atmospherically vented building drain.

The drain has a 2 inch (5 cm) air vent, which eliminates the need for a free air gap at the connection to the

building drain, unless such a gap (Figure 4) is required by local code. Do not block the air vent in any way. Do

not attach anything to the vent tube or reduce the size of the vent tube.

Do NOT use plastic pipe in the drain line, because the drain must withstand boiling water. Install the drain

line with a constant downward pitch. Do NOT create any water trap (Figure 5) in the line.

Initial Start-Up

After the Convection Combo has been installed, perform initial testing to ensure that the unit is operating

correctly.

1. Remove all literature and packing materials from the interior and exterior of the unit.

2. Make sure both cold water supply lines are open and none of the fittings are leaking.

3. Make sure that the gas supply line is open. Turn the knob of the main gas shutoff valve (Figure 6) so it

is lined up with the pipe.

4. Turn on electrical service to the unit. Because the unit will not operate without electrical power, no

attempt should be made to operate the unit during a power failure.

5. The front control panel will not operate until the pilot burners have been ignited. To light the pilot

burners, activate the pilot switch located next to the main gas valve. When the pilot ignition sequence

has been successfully completed, the red lights will glow, and power will then be supplied to the front

control panel.

6. The "trial for ignition" period is roughly 90 seconds. If the pilot burners do not ignite within about 90

seconds after the pilot switch is activated, then the ignition system automatically stops gas flow to the

pilot burner and terminates the ignition trial. If the ignition trial is terminated, turn off the pilot switch

and repeat the trial for ignition. During the initial start-up, the pilots may require several trials for

ignition to bleed air from the gas piping. Subsequent start-ups should require only about 5 seconds to

achieve pilot ignition.

NOTE: See Automatic Operation of Pilot at the end of this section.

7. Once the pilot burner flames have been established (both red lights on top of the pilot switch are on),

subsequent operator commands are executed via the front control panel touch pads. See the

Operation section for details.

8. High altitude operation. The altitude of operation can be programmed into the Convection Combo.

At altitudes above 2,000 feet (610 m), the unit will not operate in Steamer or Combo Mode unless the

altitude is set. This setting should agree with the nameplate. To set the altitude:

a. If the unit is on, turn it off by pressing the ON touch pad.

b. Press and hold the STEAM touch pad while turning the unit on by pressing the ON touch pad. The

timer display will show the letters AL and a number that represents the altitude in thousands of feet.

If the altitude has never been set on your unit, the number displayed will be 1.

c. Enter the proper altitude value, between 1 and 15, using the numbered touch pads. For example, if

the unit will be used at an altitude of 7,000 feet (2100 m), press the 7 touch pad.

d. Press the START touch pad.

9. To test Steamer Mode operation, turn on the unit. (For details of operating procedure, see the

Operation section of this manual.) Clear any time from the time display, close the door, and press the

STEAM touch pad. (If the HOT light is on, see the Fast Cool instructions in the Operation section.)

The WAIT light will stay on while the oven burners preheat the cooking chamber and the steam

generator fills with water and heats the water. Within 15 minutes the WAIT light should go off and the

READY light should come on, indicating that the water has reached the standby temperature. The

timer controls operation (in Steamer Mode only), so enter a time, then push START. The colon on the

time display will blink, and the generator will begin to produce steam. The timer will not count down, if

the READY light is not lit.

WARNING: STEAM CAN CAUSE BURNS. AVOID ESCAPING STEAM WHEN OPENING DOOR.

NOTE: You cannot change modes if the timer is running.

10. To test Combo Mode operation, turn the power on and clear any time from the timer display, Press

the COMBO touch pad. Set the COOK temperature to 300°F (150°C). The WAIT light will come on and

stay on, while (1) the steam generator fills with water and heats the water to standby temperature and

(2) the oven burners raise air temperature to 300*F (150°C ). Both actions should be completed in

about 15 minutes, starting with a cold unit. Then the WAIT light will go off and the READY light will

come on.

WARNING: STEAM CAN CAUSE BURNS. AVOID ESCAPING STEAM WHEN OPENING

DOOR.

NOTICE: The timer does not control the oven in Combo Mode or Oven Mode.

11. To test Oven Mode operation, turn the power on and clear any time from the timer display. Press the

OVEN touch pad. Set the COOK temperature to 350°F (175°C). The WAIT light will come on. Within

10 minutes from a cold start, the WAIT light should go off and the READY light should come on. When

that happens, turn the COOK temperature setting down to 300°F (150°C). The HOT light will come on.

12. To test Meat Probe operation, turn the PROBE knob clockwise to activate the probe. Confirm that

the temperature shown in the TIME display is the actual temperature of the probe. Then turn the

PROBE knob counterclockwise to inactivate the probe.

13. The heat-up times stated above may vary slightly due to differences in gas and water pressures.

14. To shut down the unit, first clear the timer. Then press the mode touch pad for the mode the unit is in.

Switch off the power. The pilot burner may also be switched off to conserve energy.

15. If the Convection Combo behaves as described, the unit is functioning correctly and ready for use.

Automatic Operation of Pilot

Once either pilot burner has been ignited, it essentially functions as a standing pilot. When the pilot switch

is on, if the pilot is accidentally extinguished (by a very strong gust of wind or the like), then it will be re-

ignited automatically. The unit will shut off completely for a few seconds while the pilot is re-ignited, then

the unit will come back on and resume operation in the mode and (running) timer value existing just prior

to shutdown. The pilot switch may be turned off during "off hours" to conserve energy.

After the unit has been running, if the pilot burner ever fails to re-ignite automatically within 90 seconds,

then wait 5 minutes before you attempt to reactivate the pilot switch. In the unlikely event that ignition

problems persist, contact your authorized Groen Service Agency.

A. Controls and Indicators

The control features routinely used by the operator are on

the right front side of the unit and are described as follows.

(Refer to Figure 7).

1. Time Section

In the Oven and Combo Modes of operation, the timer

functions only as a "cooking time minute minder" and

does not turn the unit on or off. In the Steamer Mode,

the timer controls the operation of the steaming function.

a. Display Window — Displays the operating time

remaining in the Steamer, Oven, or Combo Mode,

because the timer counts down. Format of the

display is "hours : minutes". Maximum minute

display accepted by the unit is 59. Any recipe

calling for more than 59 minutes should be

converted to hours and minutes format, e.g., 90

minutes is equal to 1 hour and 30 minutes. Display

will read 01:30.

b. Time touch pads — used to enter time values.

c. CLEAR — Pressing this touch pad once stops the

beeper and resets the timer to the timer that was

last set. Pressing twice clears the timer to 00:00.

(At the end of a cooking period, opening the door

has the same effect as pressing CLEAR once.)

d. START — Pressing this touch pad will start the

timer and, if the unit is in Steamer Mode, also

cause steaming to begin.

2. Status Lights

a. HOT— Indicates the chamber temperature is more

than 15°F (8°C) above the cook temperature

setting (see item 5 in this section).

Operation (cont'd)

b. SERVICE — Indicates a problem that may

require a service call. If such a problem has

occurred, the beeper will sound and the

SERVICE light will be on, when power is

switched on. The unit may continue to

operate, depending on the type of problem.

Refer to the Troubleshooting section to

determine the nature of the problem.

c. WAIT— Indicates the unit is either

heating or cooling toward the set

temperature. The HOT and WAIT

lights will be on together, if the

chamber is more than 15°F (8°C)

above the set point.

d. READY— Indicates the unit is ready

for use.

3. Cooking Mode Selection

These touch pads are used to select the

mode of operation. If a mode is off,

pressing the pad for that mode will switch

the mode on. If the mode is on, pressing its

pad will switch the mode off. A light just

above each pad shows which mode has

been selected

a. STEAM — Selects steamer operation. .

b. COMBO—Selects combined steam and

convection oven operation.

c. OVEN — Selects operation of the

convection oven only.

4. Power

This touch pad is used to switch the unit on

or off. When power is on, the ON light just

above the pad is lit Use of this pad does

not reset the controls, so the unit will come

on in the same mode it was in when it was

last switched off.

5. TEMP Section

a. The window displays the selected

temperature in either Oven or Combo

Mode. It is blank in the Steamer Mode.

b. Turning the knob selects the cooking

temperature in 5°F or 5°C increments. The

control ranges are:

Oven Mode 200 to 500*F (93 to 260°C)

Combo Mode 220 to 500*F (105 to 260°C)

6. Meat Probe Selection

This rotating knob is used to turn on or off the hold function. By selecting a certain temperature

(ranging between 80*F [27°C] and 200*F [93°C]) the food can be maintained at a constant

temperature for a fixed amount of time.

7. Door Lights Selection

Door lights can be turned on/off to view the food inside by using this touch pad. These lights are

not available with the optional solid door.

B. Operating Instructions

1. Steamer Mode

a. If the unit is off, switch on the electric power by

pushing the ON touch pad. (If the SERVICE

indicator lights when power is switched on, see the

Troubleshooting section.)

b. If power is already on and any number is showing

in the time display window, press the CLEAR touch

pad one or more times to reset the time display to

zero.

NOTICE: You cannot change mode while the timer is

running

c. The unit will be in the mode of operation that was

used last, so the indicator for that mode will be lit. If

the unit is not already in Steamer Mode, press the

STEAM touch pad. The STEAM indicator will light,

and the TEMP window will go blank.

d. If the unit has just been used in Oven or Combo

Mode, lighting of the HOT indicator may show that

the cooking chamber is too hot for use as a

steamer. The unit can be cooled quickly to the

proper temperature range for steaming by leaving

the door open or by following the Fast Cool

procedure described near the end of this section.

WARNING: STEAM CAN CAUSE BURNS.

AVOID ESCAPING STEAM

WHEN OPENING DOOR.

While the door is open, the generator can fill and

heat water to 200°F (93°C), but it cannot produce

steam.

e. The WAIT indicator will be lit until the water reaches

approximately 200°F (93°C). Then the WAIT light

will go off and the READY indicator will light. You

are now ready to steam foods in your Convection

Combo.

f. Load the food into the pan or pans so there is a

uniform layer.

g. Make sure the hooks on the rack are fully

engaged in the slots of the cart while raising the

rack. The pan stop should be in the center position

when moving the cart with the rack engaged.

NOTICE: Use the brakes on the rear wheels to hold

the cart in steady position.

h. Place the pans in the rack, which is on the cart. If

there are only few pans, uniformly distribute them

in the center of the rack.

i. Press the numbered touch pads to set the cooking

time. The time set will appear in the time display

window. If you enter the wrong number, press the

CLEAR pad to erase the time from the display,

then set the time again.

j. Carefully open the door, then move the cart so the

rack goes into the oven cavity. Using the hand

crank, lower the rack to the floor of the cavity.

Remove the cart and close the door.

Operation (cont'd)

k. When the correct cooking time has been entered,

press the START pad. The colon will blink, and the

timer will count down the cooking time. (The unit must

be READY before the timer can count down.)

I. Opening the door during the cooking period stops the

production of steam and interrupts (but does not reset) the

timer. Closing the door allows steaming and timing to continue.

WARNING: STEAM CAN CAUSE BURNS. AVOID ESCAPING STEAM

WHEN OPENING DOOR.

m. When the timer has counted down to zero, it will stop the

generation of steam and sound a beeper alarm. Water in the

steam generator will be held at the standby temperature (about

200°F or 93°C). The beeper will continue until the door is

opened or the CLEAR pad is pressed.

n. Carefully open the door. If the food is cooked, engage the cart

with the rack. Make sure the hooks on the rack are fully

engaged in the slots of the cart. Then crank the rack up, and

remove the rack from the oven.

o. After the timer display has counted down to zero, opening the

door or pressing CLEAR once will reset the display to the time

that was used last. Pressing START will repeat the cook cycle.

If the same cooking time will be used repeatedly, you need to

press the number keys only when you first use that time.

p. After the timer display has counted down to zero the timer can

be reset to zero by either (1) opening the door and pressing

CLEAR or (2) pressing CLEAR twice. A new cooking time

must be set by using the number keys.

2. Oven Mode

a. To use the Convection Combo as a convection oven,

first switch on the electric power by pushing the ON

touch pad. (If the SERVICE indicator lights when the

power is switched on, see the Troubleshooting

section.) The fans will begin to operate, if the door is

closed and the cooking chamber temperature is

above 200°F (93°C).

b. If power is already on and any number is showing in

the time display window, press the CLEAR touch pad

to erase the time display.

NOTICE: You cannot change mode while the timer is running.
