ROLL-IN FOOD STORAGE CABINETS & PROOFERS

SAVE THESE INSTRUCTIONS

GENERAL

The QE and EQE Series Roll-in Food Storage Cabinets are available as medium temperature (38°F)

or frozen food (0°F) storage cabinets. The QEH Series is available as a hot food (180°F) storage

cabinet. QE, EQE, and QEH Series may be ordered as one-, two-, or three-section, roll-in or roll-

through cabinets. The PEQ Series may be ordered as one-, two-, or three -section roll-in or roll-through

proofer cabinets for the baking industry. Proofer cabinets control temperature, humidity, and time.

Thaw Proofer cabinets have a two-stage control, an initial Thaw stage is automatically followed by a

Proof stage; each stage independently controls temperature, humidity, and time.

INSTALLATION

UNPACKING

Immediately after unpacking, check for possible shipping damage. If the cabinet is found to be

damaged, save the packaging material and contact the carrier within 15 days of delivery.

Prior to installation, test the electrical service to verify that it agrees with the data plate located in the

upper left corner inside the cabinet.

ASSEMBLY

Some components can be removed to allow the cabinet

to pass through short or narrow doorways.

The door handle can be removed, as follows:

1. Remove the screw and bolt from the tumbler.

2. Remove the two mounting screws and the handle

assembly (Fig. 1).

3. Replace in reverse order of disassembly.

NOTE: Proofers do not have locks.

Door(s) and hinges can be removed, as follows:

1. Lift up and remove the

front trim panel (Fig. 2).

2. Remove the screws

which secure the trim

rail cover (Fig. 2),

unplug the door switch

lead wires and remove

the screws which secure

the trim rail (Fig. 2).

Carefully lay the trim rail

on top of the cabinet —

avoid damaging or

kinking the thermometer

capillary tube.

3. Remove the three screws which secure the

upper hinge plate to the cabinet (Fig. 3).

This will remove hinge tension. Remove

the nut underneath the lower hinge plate

which secures the bottom hinge. Remove

door. Remove lower hinge plate (Fig. 3).

4. If the hinge mechanism should become

uncocked while changing the door, it will

be necessary to recock the hinge

mechanism. To do this, remove the door

from the cabinet and position the door face

down on a work table. Using a 5/16" open

end or adjustable wrench, turn the hinge

mechanism shaft 135° (Fig. 4).

5. Replace the hinge plates and door(s) in the reverse order of disassembly.

If cabinets are too tall, the refrigeration system may need to be removed in order to pass through short

openings. Contact your dealer or authorized servicer if this becomes necessary.

Once the cabinet is in its final position, replace any components that may have been removed (door

handle, etc.) and then level the cabinet front-to-back and side-to-side using shims as required.

Before installing the ramp or flat threshold, seal between the bottom of the cabinet perimeter and the

floor by applying a bead of NSF-approved sealant, such as Dow Corning 732 or GE RTV108.

Cabinets equipped with flat threshold(s) must have a recessed floor (Fig. 5). The recessed floor should

be 13/8" deep. This allows 1/4" for leveling shims.

On pass thru models, the recessed floor dimension allows 21/4" clearance at both front and rear and

1/2" on both sides. On a front opening cabinet, the recessed floor dimension allows 21/4" clearance at

the front, 11/2" clearance at the rear, and 1/2" on both sides (Fig. 5). The plug for the heater under the

flat threshold must be connected to the receptacle, provided, before installing grout.

The space between the cabinet base and the recessed opening must be filled with grout for sanitary

purposes. DO NOT fill the area below or above the hinge plate with grout, as the fastener on the bottom

of the hinge plate must remain accessible to remove the door for service. Place a piece of cardboard

around the hinge plate to make sure this area is free of any grout. Keep grout away from heater plug.

Ramp (Equipped as an Alternate to Flat Threshold)

Install ramp(s) and ramp heater(s) as follows:

The heater is secured to the bottom of the ramp

(Fig. 6). Connect the heater plug into the receptacle

provided at the bottom of the door opening (Fig. 6).

Position the ramp by placing the lip of the ramp

inside the door opening. Hook the ramp on the clips

provided at the bottom of the door opening (Fig. 6).

Ramp heaters are not used on QEH or PEQ models.

Shelves (Fig. 7)

The shelves and shelf clips are provided only if specially

ordered. Insert shelf clips in pilaster slots and install the shelves.

Index holes are provided in the pilaster to help in leveling the

shelves.

Bonus shelves are provided to fill the space between the

standard shelves. These are positioned and supported by the

standard shelves.

NOTE: Loosen all thumb screws which secure shelf pilasters

and light cover(s) prior to placing product in cabinet. Thumb

screws should be loose enough to remove with your fingers so

parts can be readily removed for cleaning without the use of

tools. Failure to comply with this request will invalidate the NSF

listing.

Miscellaneous

Some models have the compressor specially mounted to help prevent damage during shipment. If the

compressor is mounted on shipping blocks, they must be removed prior to operation. If the compressor

is mounted on springs, refer to the tag attached to the compressor.

On cabinets with remote refrigeration systems, place the condensate dish heater in the condensate

dish and connect it to the outlet provided.

PRESTART CHECKS (Refrigeration Cabinets Only)

REFRIGERANT LINES — Check for tubing shifts due to shipping that would cause operating noise,

wear, or leaks.

DEFROST TIMER (Low Temperature Units and Convertible Models in Low Temperature Mode) —

When power is initially applied to the cabinet, the exterior dial of the defrost time clock (Fig. 5) must

be set to the correct time of day.

To access the defrost timer, remove the front

trim panel (Fig. 4) by lifting up and out. Open

door on the defrost timer box. Turn the inside

knob counterclockwise until the exterior dial is

positioned so the correct time of day is at the

time of day pointer. Replace the front trim

panel when done.

The defrost timer (Fig. 5) is set at the factory

for four 26-minute defrost cycles per day (2 AM,

8 AM, 2 PM, and 8 PM). Depending on local

conditions, it may be necessary to change the

frequency or duration of defrost cycles.

If the power supply is interrupted, the defrost

timer must be reset to the correct time of day. Fig. 8

OPERATION

CONTROLS (Refrigeration)

TEMPERATURE CONTROL — The temperature control is set at the factory, but local conditions may

necessitate slight adjustment. To adjust the temperature control, lift up and remove the front trim panel (see

Fig. 2) and turn the control knob (Fig. 9 or 10) a small amount at a time. Turning the control knob in the direction

of the arrow lowers the temperature. The control knob has a marked "OFF" position which interrupts power to

the compressor and condenser fan only, not the entire roll-in.

Fig. 9 Fig. 10

STANDARD THERMOMETER (Fig. 11) — The standard

digital thermometer is calibrated at the factory and does

not permit recalibration.

OPTIONAL DIAL THERMOMETER — The optional dial

thermometer can be recalibrated. Compare the cabinet

thermometer with an accurate test thermometer. If there is

any variation, contact a Hobart-authorized Refrigeration

Service Company.

OPERATIONAL CHECK — The refrigeration and defrost

cycles should be checked for proper operation and the

thermometer(s) should also be checked for correct

temperature indication — before product is stored in the

cabinet. Fig. 11

MAINTENANCE

CLEANING

Cabinet

Clean the inside of the cabinet and the doors weekly with a warm water solution of mild household liquid

dishwashing detergent (such as Palmolive green or Ivory). Do not use anything containing grit,

abrasive materials, bleach or harsh chemicals. Be cautious with new or improved formulas; use only

after being well tested. Rinse thoroughly and dry with a clean soft cloth. Do not use steel wool to clean

surfaces.

NOTE: Failure to follow use, care and maintenance instructions may void your Hobart warranty.

Gaskets

Door gaskets should be cleaned weekly using a warm water solution of mild household liquid

dishwashing detergent (such as Palmolive green or Ivory). Never allow gaskets to contact concentrated

cleaners or disinfectants. This can cause premature failure of the gasket material.

Condenser Coil

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING THE CONDENSING UNIT.

Check the condenser coil weekly. This surface must be kept free of dirt and grease for proper system

operation. Remove the front trim panel and carefully vacuum or brush dirt and lint from the condenser

coil. Replace the trim panel.

Evaporator Coil, Drain Pan, Condensate Loop, and Condensate Dish

When needed, flush these components with fresh water. This should be a part of any routine

maintenance program and can prolong the life of the equipment.

Light Bulb Replacement

Replace light bulb(s) with 40 watt incandescent appliance type bulb(s) ONLY. The protective cover

can easily be removed and replaced.

For additional information or to discuss a maintenance program, contact your local authorized

refrigeration servicer.
