CONDITION
Case Is Not Holding Temperature
Open Air Refrigerated Merchandisers are not intended as storage
refrigerators and will not “pull down” room temperature products efficiently.
LOAD CASE INTERIOR WITH PRE-
CHILLED 38°F OR COLDER PRODUCT ONLY
Open Air Merchandisers
are subject to air disturbance and due to direct
sunlight and close proximity of heating ducts, grills, radiators, ceiling fans or
main doors.
Also, avoid locations where the unit is subject to high humidity such as near
cases with water misting or fogging devices.
Check Ambient Conditions of the Location
Most of our cases require a maximum ambient of 75°F / 55% RH (Relative
Humidity) Exceeding either or both can result in temperature issues as the
evaporator coil ices up and restricts airflow.
Check that the condenser coil is clean.
Non-refrigerated
cases do not regulate internal temperature and may be
slightly higher than ambient temperature due to lighting in the unit or direct
sunlight.
Electronic Unit Controller
Check that the control is turned on.
Control Display Is Flashing -
If the control is flashing all of its lights, it is
likely that you have a grounding issue with the power source. Verify that
the unit is properly grounded.
Check to see if the compressor run indicator is on, calling for cooling.
Check Set Point Temperature; it # 1 is the warmest and # 9 is the coldest –
set typically between 4 & 5 – adjust accordingly – control has a minimum
run time of 5 minutes and a maximum run of 60 minutes.
Supply Air Temperature – Press & Hold Down (Defrost) immediately
followed by Up (Power) – You must keep them both held to see the
temperature.
