INSTALLATION INSTRUCTIONS

REMOVE ICE MAKER FROM CARTON

1. Keep unit in the upright position, remove carton and pallet from unit and inspect unit for damage. Upon inspec­tion of unit, if any damage is found, file a claim with carrier immediately.

2. Locate Startup Card either on outside of container or on plastic liner. Fill in proper information and send one
copy to factory, and other copy to Distributor. Postage is prepaid.

CABINET REMOVAL

1. Locate and remove the (2) screws from under the front cover. Lift cover forward and up to remove.

2. Lift up front edge of top cover. Slide back about 1/2 inch and remove.

3. Remove (6) screws from the front of the machine.

4. Remove side panels by sliding the front edge out and then back slightly to disengage.

5. Remove the front splash panel by lifting slightly to disengage the front, then tilt forward and remove.

6. Remove bin top and remove shipping insert.

PREPARATION OF INSTALLATION SITE

The refrigeration system on air cooled units requires airflow, so a well ventilated area should be chosen.

1. In general a minimum of 6 inches must be maintained, free of any obstruction, for air intake. A minimum of 4
inches clearance is required for air exhaust.

2. For IMD600-30A, a minimum of 6 inches must be maintained, free of any obstruction, for air intake. A minimum
of 4 inches clearance is required at sides and 12 inches on top for air exhaust.

3. For IMD300-30A, a minimum of 6 inches must be maintained, free of any obstruction, for air intake. A minimum
of 4 inches clearance is required at sides and top for air exhaust.

4. With template provided make the necessary provisions in the counter for water, drain and the electrical hook­up. Provisions are available for rear and bottom connections of water and electrical. Use hole plugs provided to
plug unused holes.

WATER INLET HOOK-UP

1. Water Inlet - Fitting is a 1/4” SAE male flare located at the rear of the unit. Connect water supply with a 1/4” or
larger copper or flexible tubing.

2. Water Pressure - Unless otherwise specified, the unit is designed to operate on water pressures between 10
P.S.I. and 90 P.S.I. (NOTE: for pressures above 90 P.S.I. a regulator must be installed).

3. Water Cooled Condensers

A. Inlet to modulating valve uses 3/8” FPT. Use separate 3/8” or larger water line.
B. Outlet is 3/8” FPT.

4. Filter - Filter Conditioner is recommended on supply lines to ice makers. Never run the water supply to water
cooled Condenser through Filter/Conditioner, it uses up the cartridge unnecessarily and a saturated cartridge
can starve the ice maker causing premature component damage. Separate water supplies are recommended.

NOTE: Unit must be installed per local plumbing code.
