Ways the equipment should be used

The units are intended for use as a cooling

and recirculation unit for syrups and

carbonated water to provide the correct

conditioning for serving draught soft drinks

and as such should only be used for that

purpose. There are NO other recommended

uses for this equipment.

System pressure

The carbonator is an integral part of the unit

and it should be noted that the carbonation

process involves the use of high pressures

and potentially noxious gas and as such

due care should be taken when handling,

installing and maintaining the equipment

with particular regard to these hazards.

Carbon dioxide

Carbon dioxide leaks are potentially fatal if

concentrations rise to dangerous levels, in

view of this installation should be regularly

Section 2

Important

The wires in this mains lead are coloured in

accordance with the following code:

Green and Yellow Earth

Blue Neutral

Brown Live

As the Colours of the Wires in the Mains

Lead of this Appliance may not correspond

with the Coloured Markings identifying the

Terminals in the Plug to be  tted proceed

as follows:

a. The wire which is coloured Green and

Yellow MUST be connected to the

terminal in the plug marked with the

letter E or by the Earth Symbol

or coloured Green or Green and Yellow or

laser cut into the metal casing.

b. The wire which is coloured Blue MUST

be connected to the terminal in the Plug

marked with the letter N.

c. The wire which is coloured Brown MUST

be connected to the terminal in the Plug

Power isolation method

All units are  tted with a standard Euro

plug to IEC83:1975.

Before commencing any work/maintenance

a) Switch o the socket that the

plug is installed in to.

b) Remove the plug from the socket.

Rotating parts

Some components will rotate for a short

period after the power to the unit has been

switched o . These components should be

avoided until stationary.

Leakages

Manitowoc Beverage Systems has done a

complete Quality and Function Check on each

unit. Nevertheless, leakages on water lines

during operation can not be excluded totally.

To avoid expensive consequential damages

we propose that the following steps are

followed:

• Take care that any water from the water

bath over ow gets guided into a proper

drainage system.

• Take care that all water and syrup lines

to the unit are tight before operating the

system for the  rst time and that damage

through longer periods of non-operation

can be excluded (i.e. by closing the mains

water feed).

Danger by low temperatures

The evaporation temperature in the

hermetic circuit can typically be -10°C.

Without taking preventive steps, this can

be a potential source of accidents during

cleaning and maintenance.

CARB B (not applicable to this unit)

CIRC A Starts re-circulation pump

CIRC B (not applicable to this unit)

The LED’s positioned directly above the

buttons are either o ,  ashing or on

constantly. If the LED is  ashing, this

indicates the motor is running. If on

constantly, this indicates the control circuit is

switched on but the motor is on standby.

Example: The CARB A LED is constantly

on, this is indicating the control circuit is

switched on but the carbonator bowl probes

are not calling for the bowl to  ll. When the

carbonator bowl probes call for the bowl to

 ll the motor will start and the LED will  ash.

Energy Saving Mode - Description

The control board monitors the carbonator

 ll pump and if a carbonator  ll cycle has

not been detected after 30 minutes, energy

saving mode will be entered.

During energy saving mode the Agitator and

re-circulation pump switch o .

The refrigeration control will continue to

operate independently of energy saving

mode, switching on & o , when required, by

the ice bank probe.

The temperature of the re-circulating water

at the point of entering energy saving mode

determines the duration of the energy

saving “o cycle”, either 2 min, 4 min or 6 min

(see detailed description for temperature

thresholds).

At the point of entering energy saving mode

the recirculation water temperature is logged

by the software. This temperature is used as

the re-circ. pump cut in temperature for as

long as the unit stays in energy saving mode.

If the re-circulation temperature is >3.3°C

energy saving will not be entered

Energy savings cycle mode is exited when:

- Any carbonator pump cycle occurs

- Any error code occurs

- Re-circulating temperature exceeds 3.3°C

Section 4

ERC control monitors all carb motors for

entering energy savings cycle mode if no

carb cycles in 30 minutes, no ERC error

codes or sensors open / shorted, and

circulating temperature = <3.3°C (38ºf)

then energy savings cycle mode will

be entered.

Circulating LED(s) change from  ashing

(Circulating Motor ON) to constant

(Circulating Motor OFF)

NOTE: Display adds “o” to left digit to

indicate in energy savings cycle mode “oxxc”

(Centigrade) “oxxF” (Fahrenheit)

1. If circ temp = <2.2°C energy savings

cycle mode o time is 6 minutes

2. If circ temp = <2.8°C and > 2.2°C

energy savings cycle mode o time

is 4 minutes

3. If circ temp = <3.3°C and > 2.8°C

energy savings cycle mode o time

is 2 minutes

4. If circ temp = >3.3°C then no

energy savings cycle mode entered

Agitator and circulator (LED constant

when OFF) will be turned o when in

energy savings cycle mode o time.

When energy savings cycle mode o

time is completed, agitator and circulator mo-

tors will be turned on in energy savings cycle

mode on time.

Motors will stay on until temperature

entered mode is reached;

(<2.2°C, >2.2-2.8°C, >2.8-3.3°C)

Energy savings cycle mode will repeat (o time

6, 4, 2 minutes depending on entering temp,

then on again until entering temp is reached).

Energy savings cycle mode is exited when;

- Any carb cycle occurs

- Any error code occurs

- Circulating temperature exceeds 3.3°C

Display changes to normal run mode, circulat-

ing LED  ashes for controlled ON. System waits

for another 30 minute period without carb

cycle to enter energy savings cycle mode again.

Detailed Description

Initial Power-up

The control has a 30-second delay when

power is connected, or disconnected and

reconnected.

The display will initially show Pd30 before

counting down until the agitator start.

Normal Operation

Pressing the COMP/AGIT button will start the

water bath agitator immediately and initiate

the 180 second compressor delay.

The display will show Cd99 after the  rst

81 seconds have elapsed the display will

start to count down from 99 seconds. After

180 seconds the compressors and condenser

fan motors energize and the COMP/AGIT

LED  ashes.

Pressing the CARB A button will power the

carbonator tank liquid level control. The

CARB A LED  ashes to indicate the pump

is running. Note: CARB B button is not

applicable to this unit.

Pressing the CIRC A button will immediately

energize the circulating pump and energize

the LED. Note: CARB B button is not

applicable to this unit

Note: LED  ashing 1 / sec indicates energy

mode 5 is enabled. The display will show the

circulating temperature.

The compressor and condenser fan will

continue to run until ice contacts the

ice bank control probe closest to the

evaporator. When ice contacts the probe, the

COMP/AGIT LED lights constantly and the

compressor and condenser fan motor de-

energize. As the ice bank melts, the ice bank

control probe will lose contact with the ice;

the LED will  ash and the compressor and

condenser fan motor will restart. This cycle

will repeat as required depending on load.

Power Interruption

During a power interruption the control

will resume from the point of interruption

when power is reapplied and the time delay

expires. Any switches/components that were

energized when power was interrupted will

be energized when power is reapplied.
