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

38PSIG + 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

2gallons 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.
