INITIAL START UP

Pre-Start Inspection

1.Remove the front and 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 (air cooled).

4.Check that the unit is installed correctly according to the final check list (page 8).

Start Up

1.Go through the prestart inspection.

2.Open the 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. There will be a short delay before the gearmotor and compressor will start.

4.On air cooled models, the condenser will begin to discharge warm air, on water cooled models, the water regulating valve will open, and warm water will be discharged into the drain.

5.The unit should soon be making ice, if desired, the low side pressure can be checked: it should be

34PSIG + or - 4 PSIG.

The suction line temperature at the compressor is normally very cold, nearly to the point of frost up to the compressor body, but not on it.

￿The air cooled discharge pressure will depend upon air and water temperatures, but should be between 220 PSIG and 300 PSIG.

￿The water cooled discharge pressure should be

constant at about 245 PSIG.

The above numbers are for new, clean machines, you can expect to see some values higher, and some lower between different units.

6.THERE ARE NO ADJUSTMENTS TO MAKE, so replace the panels.

7.Clean and/or sanitize the storage bin interior, wipe off the exterior with a clean, damp cloth.

8.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.

9.Fill out the manufacturer’s registration and mail it to Scotsman.
