REFRIGERATED CABINETS
Refrigerated cabinet units have a POWER ON/OFF
switch located on the front of the unit for controlling power
to the unit and a Delfield's ACT-Advanced Control Tech-
nology electronic temperature control for setting the
temperature. The temperature control holds the tem-
perature between 27°F and 44°F and provides improved
pull down times, reducing compressor cycling and longer
compressor life with low energy consumption. Refriger-
ant is metered using a highly responsive thermostatic
expansion valve. The control system uses adaptive
defrost to assure evaporator coil is free of ice and
operating at optimum efficiency. Evaporator condensate
is eliminated using an energy efficient hot gas system. An
exterior digital thermostat monitors cabinet temperature.
To operate the refrigerated cabinet unit, refer to Figure 6
for location of operating controls and proceed as follows:
1. Check that cabinet is properly connected to the
power source.
2. Raise the shroud to access the controls.
3. Set the main POWER ON/OFF switch, to the
ON position.
4. Adjust the electronic temperature control to the
desired temperature.
5. Turn the unit off by placing the POWER ON/
OFF switch in the OFF position.
6. Clean equipment as discussed in the mainte-
nance section of this manual.
FREEZER CABINETS
Freezer cabinet units have a POWER ON/OFF switch
located on the front of the unit for controlling power to the
unit. Refrigerant is metered using a highly responsive
thermostatic expansion valve. The thermostatic expan-
sion valve holds the temperature between -5°F and 0°F.
Refrigerant is metered using a highly responsive thermo-
static expansion valve. Evaporator defrost is automatic
using a time initiated, time/temperature terminated sys-
tem with electric heaters. Evaporator condensate is
eliminated using an energy efficient hot gas system. An
exterior digital thermometer monitors cabinet tempera-
ture. To operate the Freezer cabinet unit, refer to Figure
6 for location of operating controls and proceed as
follows:
1. Check that unit is properly connected to the
power source.
2. Raise the shroud to access the controls.
3. Set the main POWER ON/OFF switch, to the
ON position.
4. Adjust the time/temperature control to the de-
sired temperature and time.
5. Turn the cabinet off by placing the POWER
ON/OFF switch in the OFF position.
6. Clean equipment as discussed in the mainte-
nance section of this manual.
REFRIGERATOR/FREEZER CABINET
These units combine both a refrigerator compartment
and a freezer compartment in the same cabinet. Each
compartment has its own separate refrigeration unit. A
master POWER ON/OFF switch controls power to both
compartments.
Refrigeration Compartment
The refrigeration compartment uses a Delfield's ACT-
Advanced Control Technology electronic temperature
control for setting the temperature. The temperature
control holds the temperature between 27°F and 44°F
and provides improved pull down times, reducing com-
pressor cycling and longer compressor life with low
energy consumption. Refrigerant is metered using a
highly responsive thermostatic expansion valve. An ex-
terior digital thermostat monitors cabinet temperature.
To operate the refrigerator compartment, Refer to Figure
6 for location of operating controls and proceed as
follows:
1. Check that unit is properly connected to the
power source.
2. Raise the shroud to access the controls.
3. Set the main POWER ON/OFF switch, to the
ON position.
4. Adjust the electronic temperature control to the
desired temperature.
5. Turn the unit off by placing the POWER ON/
OFF switch in the OFF position.
6. Clean equipment as discussed in the mainte-
nance section of this manual.
Freezer Compartment
Refrigerant is metered using a highly responsive thermo-
static expansion valve. The thermostatic expansion valve
holds the temperature between -5°F and 0°F. Evaporator
defrost is automatic using a time initiated, time/tempera-
ture terminated system with electric heaters. Evaporator
condensate is eliminated using an energy efficient hot
gas system. An exterior digital thermometer monitors
cabinet temperature. To operate the Freezer compart-
ment, refer to Figure 6 for location of operating controls
and proceed as follows:
1. Check that unit is properly connected to the
power source.
2. Set the main POWER ON/OFF switch, to the
ON position.
