WATER LEVEL RESERVOIR
The Float Valve is mounted in a fixed position through its mounting bracket to maintain the proper water
level in the water reservoir. For the 300 & 322 series units the bracket is mounted through the bottom hole
of the bracket.
Warning - Ice maker will not operate properly when water supply temperature is below 50°F or
above 100°F. Water supply flowing pressure must not exceed 50 PSI.
STARTING THE UNIT
After the ice cuber has been unpacked and leveled and all plumbing and electrical connections have
been made, start the unit, and check for proper operation.
A cuber has three separate circuits: the water circuit, the refrigerant circuit and the electrical circuit.
1. Start checking the water circuit by making sure that there are not thread of flare joint leaks, either
outside the unit or in the compressor section. Next check the water flow over the evaporator and
make sure that all holes in the water distributor are open (see Figure 6) and that there is no undue
splash or loss of water into the ice bin.
2. Check to see if the float valve is functioning properly and the correct water level is being maintained.
Adjust if necessary.
3. Check the refrigerant circuit by making sure that the condenser fan is running. (This will be evident
by air noise.) Is the compressor running? (Feel the casing for vibration.) Is the evaporator getting
cold?
4. Check bin-harvest switch operation. (See procedure in manual.)
