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 mode switch to ON. The auger drive

motor and compressor start, beginning the ice

making process.

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 - 4 PSIG.

The air cooled discharge pressure will depend

upon air and water temperatures, but should be

between 200 PSIG and 300 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 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 with a

locally approved sanitizer. A possible sanitizer is a

mixture of 1 ounce of household bleach to 2

gallons of water. Wash the interior of the bin with

the sanitizing solution. 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.
