P.N. 28-0720/05

Use a filter in the water line to avoid damage to the dispenser.

WARNING!

C. The carbonator pump is equipped with a strainer on the inlet side. A water supply containing any

appreciable quantity of silt, fine sand, or other debris requires a filter ahead of the pump deck.
Clean the filter cartridge periodically, depending on the condition of the water. Failure to do so
may starve the pump of water, causing it to burn out, and voiding the warranty.

1.5 ELECTRICAL SUPPLY

The dispenser must be properly electrically grounded to avoid serious
injury or fatal electrical shock. The power cord has a three-prong grounded
plug. If a three-hole grounded electrical outlet is not available, use an
approved method to ground the unit. Follow all local electrical codes when
making connections. Each dispenser must have a separate electrical circuit.
Do not use extension cords. Do not connect multiple electrical devices on
the same outlet.

ALWAYS disconnect power to the dispenser before attempting any internal
maintenance.

Only qualified personnel should service the internal components of the
dispenser. Avoid any contact with water when plugging in the dispenser.

A. Locate a standard 20 AMP, 110 VAC, 60 Hz single phase electrical power outlet with ground

connectors for the dispenser and pump deck.

1.6 INSTALLATION OF THE DISPENSER AND PUMP DECK

A Inspect the counter location where the dispenser will be installed. Verify that the counter is

strong enough to safely support a 365 pound (165.5 kg) load, after the counter cutout is made.

B. Verify that the unit will fit in the location. See below for the counter cutout dimensions.

NOTE: The unit can extend up to 23 inches (58.42 cm) below the counter, including the shipping

risers. It is recommended to keep the shipping risers attached to the dispenser. If the
dispenser ever requires removal, the shipping risers will protect the inlet tubes from being
damaged.
