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.

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.
