2. Refrigeration System Start-Up
The compressor and liquid line solenoid valve
energize after the 45 second water purge and remain
on throughout the entire Freeze and Harvest
Sequences. The water fill valve is energized at the
same time as the compressor. It remains on until the
water level sensor closes for 3 continuous seconds, or
until a six-minute time period has expired. The harvest
valve and HPR solenoid valves remain on for 5
seconds during initial compressor start-up and then
shut off.
The remote condenser fan motor starts at the same
time the compressor starts and remains on throughout
the entire Freeze and Harvest Sequences.
