Thaw Gas Check Valve
Water Flush Solenoid Valve (63)
is opened during the thaw (harvest) cycle, to flush out some of
the impurities form the water in the tank, thereby improving the ice quality. Repair or replace as
follows:
1.
Turn off the water supply to this valve.
2.
Dismantle the valve and inspect for dirt, etc., and wear. Reverse osmosis water can cause
premature wear and erosion of the brass parts of this valve, you may want to consider replacing
the valve with a stainless steel valve.
3.
Repair or replace the valve as needed.
4.
Turn on the water supply and check for leaks.
Compressor Cooling Solenoid Valve
(64)
is opened all the time the compressor is running. It
provides water for cooling the compressor oil and heads. There should be no water flow through the
compressor heads when the compressor is not running. Water through the heads (water jackets)
during off times could cause liquid ammonia condensing in the crankcase and dilute the oil or slug
the compressor at start up. Repair or replace this valve by following the same procedure outlined for
the Water Flush Valve (63).
Compressor Oil Changing
See Table 7-4 for frequency recommendations.
1.
Turn off power to the machine and make sure the compressor crankcase heater is not energized.
2.
Drain the oil through the oil drain valve located at the base of the compressor.
3.
When all oil is drained, new oil of the required specifications can be pumped into the crankcase
to the proper level.
4.
Turn the power on and allow the crankcase heater to warm the oil prior to start-up. Be sure to
confirm sufficient oil pressure at start-up.
5.
Restore power to the crankcase heater allowing time to warm the oil. Be sure to confirm
sufficient oil pressure at start-up.
Compressor Inspection
1.
Close the compressor suction valve and allow the machine to stop by low pressure cut-out.
2.
Close the compressor discharge valve, oil return stop valve. Disconnect and lock-out all power to
the machine.
