Inspection
When the equipment is received, all items should be carefully checked against the bill of lading to make sure all crates
and cartons have been received. All units should be carefully inspected for hidden damage when received. If any dam-
age is found, it should be reported to the carrier immediately and a claim should be filed. The unit nameplate should be
checked to make sure that the voltage agrees with the power supply available.
Expansion Valve
Install expansion valve and feeler bulb inside cabinet of the unit. Recommended valve sizes are given for each
product family.
Installation
Installation and service of this equipment should be performed only by qualified and experienced commercial refrigeration
mechanics. Correct application and installation of this equipment is necessary to obtain optimum performance and
customer satisfaction. Install all equipment, piping and electrical in accordance with local and national codes and in
conformance with good practice required for proper operation. Work safely! Prevent accidents!
The final step in any installation is to instruct the customer or user in the operation of the equipment. The customer
should be shown how the equipment can be made to operate properly and efficiently. Maintenance requirements
should be explained.
Drain Line
After installing the fan panel assembly, connect the drain line to the fitting provided on the unit. A plastic hose or
metal drain line can be used.
The drain line should be pitched sharply and exit the cabinet as quickly as possible. Traps in the drain line should
be located in a warm ambient to prevent freeze-up.
If only a small portion of the drain line is located in the refrigerated area, a drain line heater will not be required.
If a drain line heater is required, use approximately 15 watts per foot of pipe. Connect the heater wire to the
terminals of the heater circuit (N and 3) at the terminal block in the junction box. The heater will then operate
during the defrost cycle.
All condensate water must be disposed of properly and should not be allowed to accumulate or cause a safety
hazard.
General Information
NOTE: Installation and maintenance are
to be performed only by qualified
personnel who are familiar with
local codes and regulations, and
experienced with this type of
equipment.
CAUTION: Sharp edges and coil surfaces are
a potential injury hazard. Avoid
contact with them.
Motors
Motors are lifetime lubricated and thermally protected. Check an inoperative motor by disconnecting and applying
correct voltage across leads. If test fails, replace the motor.
Wiring
The nameplate on the unit is marked with the electrical characteristics to be used for wiring the unit. The unit must
be grounded. All wiring should be done in accordance with applicable national and local codes.
Maintenance
Periodically inspect unit for grease and soil accumulation. Clean with warm water and soap. Do not use cleaners containing
ammonia. Inspect the drain pan/fan panel occasionally for proper condensate drainage. Keep the drain opening clean.
WARNING: All power must be disconnected before cleaning drain pan/fan panel. It serves as a cover
of hazardous moving parts. Operation of unit without pan in place constitutes a hazard.
WARNING: Refrigerant can be harmful if it is inhaled. Refrigerant must be used and recovered
responsibly. Failure to follow this warning may result in personal injury or death.
