START UP
Pre-Start Inspection
1. Remove the front, left, and right side service
panels.
2. Check that any shipping blocks have been
removed.
3. Inspect the interior of the machine for loose
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 and that the compressor domes
are warm.
6. Check that the unit is installed correctly
according to the final check list on page 12.
Start Up
1. Go through the pre-start inspection.
2. Open the hand valve, observe that water enters
the water reservoirs, fills the tubes from the
reservoirs to the evaporators, and then shuts off.
Check for leaks.
3. Open each King (receiver service) valve.
4. Switch each master switch on.
The electrical start up sequence is automatic.
There will be a short (15 second) delay before the
gear motor starts and the liquid line valve opens,
after that 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 of each system can be
checked, it should be 32 psig + or - 2 psig. The
discharge pressure will depend upon air and water
temperatures, but should be between 205 psig and
280 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
him/her in the operation of the unit, and make sure
they know who to call for service.
10. Fill out the manufacturer’s registration and mail
it to Scotsman.
