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 automatic; there will be a short (15
second) delay before the machine starts.
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
38 PSIG + or - 2 PSIG.
The air cooled discharge pressure will depend
upon air and water temperatures, but should be
between 240 PSIG and 340 PSIG.
Water cooled discharge pressure should be about
245 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 holding a container in
front of the Touch Free ice sensor (just below the
ice delivery spout). Ice should flow from the spout
when a container is present, and stop dispensing
when the container is removed.
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
2 gallons 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 Customer Evaluation and Warranty
Registration form, and mail it in to Scotsman.
