This equipment is to be installed to comply with the applicable Federal, State, or local plumbing codes having
jurisdiction. In addition:

that the machine can be moved for cleaning underneath.
2. An approved back flow prevention device, such as a double check valve to be installed between the
machine and the water supply.
The unit is equipped with a ¼" Flare Water Inlet Fitting which is located on the back of the control box.
NOTE: Connecting the water boiler to a warm water supply will speed up heating and recovery times.
HIGHLY RECOMMENDED:
A WATER SHUT-OFF VALVE and A WATER FILTER, preferably a combination Charcoal/Phosphate
Filter, to remove odors and inhibit lime and scale build up in the unit.
Note: In areas with extremely hard water, a water softener must be installed in order to prevent a
malfunctioning of the equipment and in order not to void the warranty.
PRIMING AND FILLING A UNIT:
Connect unit to power line (plug cord into line for 120V unit or turn on switch for the 208/240V units). Turn
