– continued
1. Di rty condenser.
(Air Cooled Remote Only)
1.
Clean condenser.
2. Shortage of refrigerant.
2.
Remove charge into a refrigerant
recovery/recycling unit, repair leak,
evacuate and recharge system.
3. Moisture in the system.
3.
Remove charge into a refrigerant
recovery/recycling unit, evacuate and
recharge system.
Unit operates
long or
continuously.
4. Glycol system problem.
4.
Check glycol system.
CAUTION: When evacuating either side of a double freezer DO NOT OPERATE THE
OPPOSITE SIDE. All control switches must be in the "OFF" position and the main power supply
disconnected. If power is applied to a compressor in a vacuum a short may occur. CAUSING
PERSONAL INJURY.
5. Compressor failing.
5.
Check compressor for proper
pressures. Replace if inadequate. Pump
down to at least 10 inches vacuum and
should hold vacuum for 5 minutes.
1. Water turned off or defective water
regulating valve.
1. Turn on water, replace regulating valve, or
install water valve kit.
2. Restricted water cooled condenser.
2. Clean or replace condenser.
3. Dirty condenser.
3. Clean condenser.
4. Unit location too warm.
4. Relocate unit away from restriction. Place
nothing against the back of the unit.
5. Hooked to hot water line.
5. Connect to cold water line.
Discharge
pressure too
high.
6. Glycol system problem.
6. Check glycol system.
CAUTION: When evacuating either side of a double freezer DO NOT OPERATE THE
OPPOSITE SIDE. All control switches must be in the "OFF" position and the main power supply
disconnected. If power is applied to a compressor in a vacuum a short may occur. CAUSING
PERSONAL INJURY.
7. Refrigerant overcharge.
7. Bleed refrigerant charge into a refrigerant
recovery/recycling unit, until sight glass
bubbles (Flashes) then add refrigerant
until sight glass clears.
8. Air in system.
8. Purge system into a refrigerant
recovery/recycling unit, evacuate and
recharge.
