MFI Series

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 ice machine for loose screws or wires.

4.Check that no refrigerant lines are rubbing each other.

5.Check that the fan blades turn freely (Air Cooled).

6.Check that the unit is installed correctly according to the final check list on page 8.

Start Up:

1.Go through the pre-start inspection.

2.Open the hand valve, observe that water enters the water reservoir, fills the tube from the water reservoir to the evaporator and then shuts off. (Water cooled only, Turn the water supply ON to the water cooled condenser). Check for leaks.

3.Switch the master (mode) switch ON. The electrical start up sequence in automatic.

a.There should be a short (15 second) delay before the gear motor starts.

b.After the gear motor starts, the 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 may be checked: it should be 32 psig +/- 2 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 200 psig and 280 psig.

The water cooled discharge pressure should be a constant at about 245 psig.

Note: The above pressures 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 Ice-O-Matic.
