INITIAL START UP
Pre-Start Inspection
1. Remove the front, left, and right side service
panels.
2. Check that any styrofoam shipping blocks have
been removed.

screws or wires. Check that no refrigerant lines
are rubbing each other. Check that the fan blade
turns freely (remote condenser).
4. Check that the refrigerant lines are properly
installed.
5. Check that the electrical power has been on for
at least 4 hours.

according to the final check list on page 11.
Start Up

will open, the low pressure control will close and
the compressor will start.
5. The remote condenser fan turns, and the
condenser begins to discharge warm air.
6. The unit should soon be making ice, if desired
the low side pressure can be checked, it should be
30 PSIG + or - 4 PSIG. The discharge pressure will
depend upon air and water temperatures, but
should be between 180 PSIG and 300 PSIG.
7. THERE ARE NO ADJUSTMENTS TO MAKE,
so replace the panels.
8. Clean and/or sanitize the storage bin interior,
wipe off the exterior with a clean, damp cloth.
9 Give the owner/user the service manual, instruct
