To comply with Sanitation requirements, the cabinet must be mounted on legs (6” high minumum) or the base

must be sealed to the floor using N.S.F. listed RTV silicone sealant. Minimum clearance as follows: 0” rear

and side, top and front are open required for compliance.

GRILLE REMOVAL AND COMPRESSOR CHECK

Remove grille and check refrigeration lines to see that they are free (not touching each other or

compressor). Spin condenser fan blade to see that it is free.

Check that all service valves (2) are open (if equipped). The compressor is hermetic, it is internally spring

mounted and ready to run.

Hermetic Compressor

STARTUP

FAN OPERATION AND VIBRATION; VOLTAGE CHECK

Uncoil the lead cord and pass it through the hole provided in the cover. While the cabinet is in operation, check

the voltage draw and the amperage draw versus this rating on the nameplate. Check for fan noise and

vibration, while the fan is running. Voltage should be checked at the compressor terminals while the

compressor is initially starting. The unit is designed to operate at +/- 10% of 115 volts, 60 cycle, single phase.

This means that the voltage should be between 103 and 126.5 volts.

THEROMSTAT CHECK

After the cabinet has pulled down in temperature to approximately 0°F at load line, check the thermostatic

control by turning it to its warmest position. This should shut the compressor off. Also check that the main

double-pole double throw toggle switch turns the refrigeration system and cabinet lights. A separate circuit for

each cabinet is recommended to avoid the possibility of other appliances on a circuit overloading the circuit and

causing a malfunction. Make sure that the electrical service is grounded upon installation.

DEFROST AND TEMPERATURE CONTROL SETTINGS

The GT cabinet has a temperature control that is adjustable from #1

(warmest setting) to #9 (coldest setting). Turn the control knob in

line with the punch mark to the desired setting. The temperature

control is located near the condensing unit at the bottom of the

cabinet.
