Part Number Preliminary 6/11 217
COLUMN 3 - TXV FLOODING OR REFRIGERANT
OVERCHARGE
A loose or improperly mounted expansion valve bulb
causes the expansion valve to flood. Check bulb
mounting, insulation, etc., before changing the valve.
Verify refrigerant amount is correct by weighing
recovered refrigerant before replacing a TXV. On
Quad evaporator machines, the service technician is
able to tell which TXV is flooding by comparing the
evaporator outlets. Change only the flooding
expansion valve. On dual expansion valve machines a
third and fourth valve are not available for comparison
and both valves will need to be changed.
COLUMN 4 - COMPRESSOR
Replace the compressor. To receive warranty credit,
the compressor ports must be properly sealed by
crimping and soldering them closed.
COLUMN 5 - HARVEST PRESSURE VALVE
LEAKING (I3300W ONLY)
Replace the valve as required.
