MAKE ELECTRICAL POWER SUPPLY CONNECTION

Requirements: 115V/60 Hz 1 ph., 230V/60 Hz. 1 ph., or 220V/50 Hz. 1 ph when used.

Refer to serial plate for minimum circuit ampacity and maximum time delay fuse size.

All wiring must conform to national and local electrical codes.

MAKE PLUMBING CONNECTIONS

Water supply -- (install per local codes) (See diagram 3).

The water inlet connection to the unit is a 3/8”male flare connection located at the rear of the ice machine.

WARNING: If the water pressure exceeds 50 pounds, a water pressure regulator should be installed in the water inlet line between the water shut--off valve and the strainer.

Install a reducer fitting on the shut--off valve to accommodate the water stainer, which is supplied with each ice machine and MUST be used. This is very important for cleaning. Connect either 3/8”or 1/2”copper tubing be- tween the water inlet fitting of the ice machine and the water strainer.

For water cooled units

Two water inlet connections are provided. One for the ice making (evaporator) section which is located on the back of the machine and is a 3/8”flared connection. The other is for the water cooled condenser.

The reason for the separate water inlet connections is that some installations use a water tower for cooling the water used in the water cooled condenser and some installations use treated water (filtered) for the ice making inlet water connections. Be sure to install water line (incoming) to the 3/8”male flare connection on the back of the unit that supplies water to the water regulating valve inside. The setting of the water regulating valve from the factory should be 200 pounds for R--22 units. NOTE: Always flush out water lines before starting unit. Ad- justments, if necessary, should be done at installation.
