After turning the
ON/OFF
switch to
ON
the unit’s com pres sor
will begin operating. Delfield display cases are designed to
maintain an operational temperature of 36°F to 40°F (2°C to
4°C) in both the display (F5 and F15 Series) and storage areas
(F15 Series only).
Located on the operator side at the top right is an
ON/OFF
switch for the display lights.
The display temperature control is located in the fan shroud. The
F15 base thermostat is located in the mechanical compartment.
Use the knob to adjust the temperature, 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.
Continuous opening and closing of the doors will hinder the
unit’s ability to maintain operational tem per a tures.
If humidity is above 55%, condensation on the glass
will be present.
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:
1. During the cooling mode, compressor and evaporator fan
run simultaneously.
2. During the compressor off mode, evaporator fan pulses
three minutes on and three minutes off.
3. During an actual defrost event other than the off-cycle
defrost, compressor stays off but the evaporator fan runs
continuously.
