START-UP & OPERATION
Start-up Checklist. Be sure to complete and return the “Warranty Registration/Start-up Report”
located in the front of the manual.
1. See that the water-inlet connections are attached properly. The water inlet shutoff valve (62) for
the water tank should be open. The water level in the water tank should be at a height where the
make-up float valve will be closed when the machine is idle and water is not running out of the
overflow (9).
2. See that the condenser cooling water is connected properly and the valves are opened for
circulation.
3. Fill the cooling tower sump and check the tower manufacturer’s installation and operation
instructions to make sure it is ready to run.
4. Check condenser cooling water pump rotation.
5. Check rotation of augers or ice handling equipment to make sure they are rotating in the proper
direction.
6. Check all tagged valves and make sure they are in their correct operational position (opened,
closed, or automatic).
7. See that the electrical disconnect is closed and the proper power is supplied to the machine.
8. See that the compressor oil temperature is 100-110°F and there is no liquid refrigerant in the
crankcase. The oil level should be 1/2-3/4 of the sight glass.
9. Check the elapsed time indicator (ET) and make sure wire #22 and #27 are attached.
10. Reconfirm “Rotation Check” for compressor, cutter and water pump (See Section 3).
Refrigerant Charge. Prior to shipping, the machine is charged with the required amount of
refrigerant and pumped down to the condenser / receiver. All valves tagged prior to shipping must
be opened prior to starting the machine.
Total refrigerant charge required is approximately; P34F = 2400 lbs of R22 & R404a.
