2.0 operatIon
NOTE: Installations above 6000 feet, 1825 meters
Unit is adjusted to operate in altitudes up to 6000 feet,
1825 meters. If unit is installed in an altitude above this,
and has not been preset at the factory for this altitude,
contact Manufacturer’s Service Department.
2.1 Start-up
Start refrigeration system by pushing the on/off switch
to the ON position (depress rocker switch on side marked
“I”).
NOTE: The fault light may illuminate when unit is ener-
gized. Light should go out approximately 5 minutes
after start-up. If light remains lit after 30 minutes or illu-
minates after going out, refer to Troubleshooting Guide.
2.2 Operating check points
Check the following on a periodic basis:
A. Rocker switch is in the ON position.
B. Amber fault light is out.
C. Condensate is being regularly discharged.
2.3 Minimum/maximum operating conditions
A. Minimum/Maximum air pressure: 20/250 psig,
1.4/17.6 kgf/cm
