HANDLING & INSTALLATION 9
QUAD DOOR HARDENING FREEZER
These cabinets were developed for low temperature storage
(-30°F, -34°C + -40°F, -40°C). Defrost timer to be set 8 A.M.,
4 P.M. and 12 P.M. Failsafe to be set at 30 minutes. Defrost
will terminate by time only. The temperature control is
located on the side of the electrical box. It can be adjusted
without removing the upper control panel.
Ways to Minimize Frost & Ice
Buildup Inside Hardening Freezers
Moisture-laden air migrates into the freezer during door
opening and under normal operation, will be absorbed or
removed by the refrigeration system and the defrost cycle.
The lover the temperature is in the freezer, the more rapidly
frost and ice will accumulate. Opening doors frequently will
also increase frost and ice buildup.
There are several things that you can do to reduce the
accumulation of lice/frost on the interior parts of the cabinet
and product. If this icing condition exists, the following items
should be checked and corrected as required.
1. Minimize door openings by using the hardening freezer to
harden the product, then move to a storage or display
freezer that is less critical in temperature.
2.Keep the length of time door is open to a minimum.
3. Avoid opening all doors at once. Open only one of the
outer doors plus only one of the inner doors (top or bottom)
at one time on the hardening freezer.
4. Check the door gaskets for possible air leaks. Look for
frost patches around the door openings of both the inner and
outer doors. Make sure that gasket seals all around door
opening; any leak will allow moist outside air to enter the
cabinet.
5. Make sure the inner door latches work properly.
6. These freezers are designed to operate in a range of -15°
to -40°F. Keep freezer thermostat set as high as possible to
minimize frost buildup.
7. Look for moisture draining from the drain tube at the rear
of the cabinet during and and after a defrost. This is normal
and tells you that the unit is going through the proper defrost
cycle.The drain must be properly trapped as shipped from
the factory.
8. Evaporator defrost heater and the drain tube heater must
work properly and have proper voltage supply. The one- and
two-door freezers are rated at 115 volts.
9. The defrost heater and drain heater must be in their
proper locations.
10. Ensure that the freezer is sealed where tubing enters
upper lefthand corner of the cabinet.
11.The freezer should not be located where excessive drafts
from doors or air conditioning vents can blow into it.
GROUNDING INSTRUCTIONS
This appliance is equipped with a three-prong (grounding)
plug for your protection against shock hazards. The
appliance should be plugged directly into a properly
grounded three-prong receptacle.
Where a two-prong wall receptacle is encountered, it must
be replaced with a properly grounded three prong
receptacle in accordance with the National Electrical Code
and local codes and ordinances. The work must be done by
a licensed electrician.
WARNING
Consult a licensed electrician if you have any doubt about
the grounding of your wall receptacle. Only a licensed
electrician can determine the polarization of your wall
receptacle. Only a properly installed three-pronged wall
receptacle assures the proper polarization with the
equipment plug.
NOTE:
These cabinets come from the factory
with defrosts set from 8 a.m., 4 p.m.,
and 12 a.m. on a 24-hour cycle. Do not
adjust the failsafe time since the
freezers terminate on time only.
IMPORTANT
Do not under any circumstances cut or remove the
round grounding prong from the equipment plug.
SERIAL RATING PLATES
Serial Number Rating Plates on each vertical cabinet are
located on the inside upper left hand corner. This plate
