INITIAL START UP
Pre Start Inspection
1. Remove the two front panels.
2. Check that all shipping blocks have been
removed.
3. Remove any and all packing tape (check inside
the storage bin).
4. 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 on air
cooled models turns freely.
5. Check that the machine is installed correctly
according to the final check list.
Start Up
1. Go through the pre start inspection.
2. Open the water hand valve, observe that water
enters the water reservoir, fills the tube from the
reservoir to the evaporator and then shuts off.
Check for leaks.
3. Switch the master switch on. The electrical start
up sequence is now on automatic:
A. There will be a short (15 second) delay before
the gearmotor starts.
B. After the gearmotor starts, the compressor will
start.
4. On air cooled models, warm air will begin to flow
from the condenser. Water cooled models will
begin to discharge warm water down the drain.
5. The unit should soon be making ice. If desired,
the low side pressure may be checked: it should
be 30 PSIG + or - 4 PSIG.
The air cooled discharge pressure will depend
upon air and water temperatures, but should be
between 200 PSIG and 280 PSIG.
Water cooled discharge pressure should be about
220 PSIG. If needed, adjust the water regulating
valve.
The above numbers are for new, clean machines.
Field values may be somewhat higher or lower.
6. There are no adjustments to make, so replace
the panels.
7. Check ice dispensing by pushing in on the glass
filler lever. Ice dispenses are portion controlled; by
turning a knob, the length of time the unit
dispenses when the glass filler lever is pushed
(and the amount of ice dispensed) is adjusted.
8. Switch off the icemaker-dispenser, remove the
top panel and the top of the ice storage bin.
Sanitize the interior of the ice storage bin by wiping
it with a mixture of 1 ounce of household bleach to
1 gallon of water, allow to air dry. Replace all
covers and panels. Switch the icemaker-dispenser
back on.
9. Give the owner/user the service manual, instruct
him/her in the operation and maintenance
requirements of the unit. Make sure they know
who to call for service.
10. Fill out the warranty registration card, and mail
it in to Scotsman.
11. Fill out the field Quality Audit form, and mail it
to Scotsman.
