Operation
Section 3
230-240 Volt Export Operation
After turning the ON/OFF switch to ON the unit’s
compressor will begin operating. Located on the operator
side at the top right is an ON/OFF switch for the display
lights.
Temperature Control
Display and base temperature is controlled by separate
thermostats. The display temperature control is located in
the fan shroud. The F15 base thermostat is located in the
mechanical compartment.
• The thermostat is set at 2.5 at the factory to provide
proper operation.
• To adjust the temperature, turn the knob clockwise as
indicated on the control. Settings are from 1 through 9
(9 being the coldest).
• Adjustments should be made gradually.
• Several small adjustments will be more effective than
one large adjustment.
• It may take an hour or longer to realize the temperature
change depending on the application and location of
the unit.

Export 230-240 Volt Pressure Control
The export display cases have a high pressure limiting
device. Under severe overloading conditions, or in the
event of a condenser fan failure or a plugged or blocked
condenser, this device may shut down the refrigeration
system. This device will automatically reset, but determining
the cause of the high pressure condition should be
investigated by a qualified refrigeration technician.

Caution
In attempting to adjust the pressure control, you can
do damage to your unit. Please contact Kitch1
(844) 724-2273 or your local service agent. Delfield is
not responsible for charges incurred while having the
pressure control adjusted.

F15 Refrigerated Base Evaporator Fan Operation
When the refrigerator is initially powered up or immediately
following a power outage the unit will begin cooling after a
3-6 minute delay. During normal operation the evaporator
fan pulses independently of the compressor as dictated by
the controller as follows:
• During the cooling mode, compressor and evaporator
fan run simultaneously.
• During the compressor off mode, evaporator fan pulses
three minutes on and three minutes off.
• During an actual defrost event other than the off-cycle
defrost, compressor stays off but the evaporator fan
runs continuously.
