DIAGNOSTICS

When any of the following faults occur, the following will
happens:
1. An alarm sounds
2. The water pump stops operating
3. The refrigeration system stops operating
LOW WATER LEVEL SWITCH:
The LOW WATER LEVEL SWITCH is located on the front
wall of the water tank. It floats upward when water level is
above a minimum level, and falls down when the water falls
below the required minimum level.
WHY THE LOW WATER LEVEL SAFETY
SWITCH IS IMPORTANT
If the water level in the tank falls below the
factory minimum level, air will be sucked into
the water pump and eventually allow it to
operate dry. When this happens, the pump
seals and vanes will burn out to destroy the
pump head. Permanent damage can easily
occur to the compressor at this point.
DO NOT DEFEAT THE WATER LEVEL SAFETY
