HANDLING & INSTALLATION-Illuminated Dipping Cabinets
FREIGHT DAMAGES AND SHORTAGES
IMPORTANT
The cabinet was inspected and packaged at the
factory, and should have arrived in excellent
condition. The transportation company or other
parties involved in the shipment are responsible for
loss and/or “damage.” Always make an inspection
before and after uncrating, pref erab ly at the point of
unloading by the transportation company.
INSPECTING FOR DAMAGES
Note:
Always use care when removing shipping tape,
blocks, pads, hardware or other material. Contact
your dealer or distributor if technical assistance
is required.
Check the cartons or containers. If these are damaged
in any way, open them and inspect the contents in the
driver’s presence. If damage is detected, do the
following:
1. Have the driver note the nature and extent of the
damage on the freight bill.
2. Notify the transpor tation company’s office to request
an inspection. Carrier claim policies usually require
inspections to be made within 15 days of delivery.
3. If damage is noticed, file a claim with the
transportation company.
FILING A CLAIM
File a claim for loss at once with the transportation
company for:
A. A cash adjustment B. Repairs C. Replacement
When filing your claim, retain all packaging materials
and receipts.
HANDLING THE CABINET
Note:
The refrigeration system of the cabinet is designed
to operate with the cabinet located on a flat surface.
Do not tilt the cabinet more than 30° to any side. If
the cabinet must be tilted on an angle for handling or
moving purposes, allow it to sit in an upright position
20 to 30 minutes prior to operating.
CHOOSE A LOCATION
This model cabinet should be situated to allow proper air
circulation. The cabinet must be installed on sturdy, level
floor and positioned so that it can be plugged into a
properly grounded three-prong electrical wall outlet. The
electrical outlet should not be controlled by a wall switch
which might be turned off accidentally.
UNCRATING THE CABINET
The cabinet should be moved as close as possible to
the operating location before removing the skid. Be
sure to follow the steps in the “INSPECTING FOR
DAMAGES” instructions.
INSTALLING THE CABINET
Whenever possible leave the crate skid on the cabinet
until it is moved close to the final position. When it is
necessary to move the cabinet through a doorway, it
may be necessary to remove the crate skid.
Run the cabinet down to storage temperature before
adding product.
CAUTION
A. Do not locate cabinet where sunlight or drafts from
fans, air conditioners or open doors can affect product
temperature.
B. Run cabinet before building in or attaching panels or
accessories.
C. Employee side access panel must be kept clear for
adjustments and service.
D. Cabinet must be installed on the finished floor to
assure rear raceway cover and condensing unit
(employee side) can be pulled or removed for service.
DO NOT seal in with cover molding or caulking in the
area where condensing unit pulls out.
E. Do not use extension cords to power this equipment.
Run any necessary electrical, water supply and drain
lines before setting the cabinet in position. Shim under
the cabinet as necessary to level it. N.S.F. approval
requires sealing the cabinet to the floor. This can be
done by applying a bead of mastic sealer between the
cabinet bottom flange and the floor.
Should several cabinets be set up in a row, space is
provided in the rear toe space for routing electrical and
plumbing lines.Access to this space requires removing
screws and the metal cover which runs the length of the
cabinet.
Rivnuts are provided on the operator's side for
mounting dipperwell and other accessories.
CABINET START-UP
Once the cabinet has been located in its permanent
location and the proper power and grounding have
been provided, the following items must be checked or
completed:
A. Cut and remove the compressor hold-down band (if
applicable) so the compressor “floats” freely.
8 INTRODUCTION
B. Check for traces of oil on the compressor pan which
could mean a broken or leaking refrigeration line.
UNDER NO CIRCUMSTANCE SHOULD THE
COMPRESSOR BE STARTED WHEN OIL IS
PRESENT UNTIL INSPECTED BY A SERVICE
TECHNICIAN.
C. INSPECT THE FACTORY WIRING FOR
TERMINALS THAT MIGHT HAVE VIBRATED
LOOSE IN SHIPPING. TIGHTEN ALL SCREW
TYPE TERMINALS.
D. Check the refrigeration lines to see that they are
“free” and no damage was done during shipping.
E. Check fan blade for free operation.
F. Turn on the main power switch.Once the compressor
starts, the voltage should be checked at the
compressor terminals to determine if there is proper
voltage to the compressor. The voltage should not
exceed the 10% above or below the rated
compressor voltage.
EXAMPLE: If the voltage reads 220 volts with no load
and it drops below 210 volts when the compressor
starts, it may indicate that the supply wiring is too small
or that the wire run is too long.
G. Listen for any unusual noise such as lines vibrating,
etc. Correct the problem by tightening screws,
slightly bending tubing, etc.
H.The temperature control thermostat which is located
in the rear post is factory set for average conditions.
A customer adjustment requires a coin or
screwdriver to turn the slotted shaft.A numbered dial
makes it easy to keep track of adjustments. #1 is
warmest setting and #7 is coldest setting. An “OFF”
position is provided for your convenience in
defrosting the cabinet.
I. Allow the cabinet to pull down and cycle prior to
loading with product (Approx. 24 hours).
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.
IMPORTANT
Do not, under any circumstance, cut or remove the
round grounding plug from the appliance plug.
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 threepronged wall receptacle assures the proper
polarization with the appliance plug.
IMPORTANT USAGE INSTRUCTIONS
Dipping Cabinet
The cabinet must be located in an area free from air
drafts created by open doors, air conditioning ducts,
and fans. The cabinet should not be located in the
direct sunlight.
The rear grill must be clear of any obstructions so the
intake and exhausting of air f or the condensing unit can
move freely.
Dipping cabinets are designed for use in an air
conditioned store. This cabinet is designed for
merchandising, not hardening of the product.
High humidity can cause fogging of the lid and front glass.
High temperatures, installation of warm product and
heavy usage can cause the product to soften. This
condition will be more noticeable at the top of the cans.
The corners of the cabinets are the coldest areas.
These areas should be used for product that is more
difficult to keep firm.
Frost and ice act as insulators. The need for defrosting
will depend on usage and product firmness.
If the frost is scraped daily with a plastic scraper,
intervals between complete defrosting may be
extended.
Thermostat adjustments should be made one
increment warmer or colder allowing 24 hours between
adjustments to allow the product to stabilize.

Principles of
Operation

GENERAL OPERATIONS
All the dipping cabinet models are of the same basic
design, consisting of a bare tube condenser and a cap
tube fed tank wrap evaporator.
Ice formation on the walls over a period of time is
normal. This frost should be scraped off periodically in
order to maintain peak performance. These cabinets
are thermostatically controlled for various temperature
requirements.The thermostat is located post adjacent
to the unit compartment and can be accessed for
adjustment by the user with a screwdriver or a dime.
Thermostat position #1 being the warmest and
position #7 the coldest.
These cabinets are manual defrost and a drain is
provided for periodic cleaning. A garden hose can be
attached to the drain plug for draining away any water
that might have accumulated.This drain attachment is
located in the front base rail of the cabinet.NOTE:The
power supply cord must be disconnected when
cleaning or servicing these cabinets.
NOTE: On initial cabinet pull down the bare tube
condenser may become warm to the touch until
the normal operating temperatures are achieved.
Compressors being used in these cabinets utilize
refrigerant 404A and polyol ester oil. Because of the
hygroscopic nature of this oil, extreme care must be
taken when any component is changed within the
system. In the case of compressor replacement, work
should be completed before the caps are removed
from the compressor.
Agitation of the oil should be kept to a minimum.
Compressors should not be open to the atmosphere
for more than 15 minutes max. Should contamination
occur the oil can be removed and recharged (following
compressor manufacturer's guidelines when
performing this procedure). Because of the porous
nature of plastic, polyol ester oil should be stored in a
metal container. Moisture contained within the oil
cannot be removed even under high vacuum
conditions and must be replaced.
Refer to model serial data tag for cabinet amperage,
refrigerant charge & type.
