PLUMBING INSTALLATION
1. Install provided 1" drain valve on unit drain. Plumb to an
appropriate waste as required by local plumbing and sanitation
ordinances.
IMPORTANT:
DO NOT allow the sink drain spud to turn during installation.
Hold the spud with an appropriate cross-guard-style spud wrench,
or carefully grip the center threaded portion with a strap wrench or
slip-joint pliers to immobilize the drain spud during drain fitting
installation.
DO NOT grip the drain spud nut or gasket.
2. Install provided backflow preventer assembly to the tank water in-
let. Attach water outlet tubing from water connection (located on bot-
tom left of control unit) to the inlet of the backflow preventer.
NOTE: While a backflow preventer is incorporated into the unit,
local codes may require an additional backflow preventer or
vacuum breaker in the water inlet line.
3. The unit must be connected to a potable cold water supply line with
average pressure between 20 PSI and 90 PSI. If your water
pressure exceeds 90 PSI at anytime, a pressure regulator must be
installed in the water supply line to limit the pressure to not more
than 90 PSI in order to avoid damage to lines and solenoid. Install
water supply to inlet fitting (located on left side of control unit) with
a 1/4" female flare.
4. A water shut-off valve should be installed on the incoming water
line in a convenient location (Use a low restriction type valve, such
as a 1/4-turn ball valve, to avoid loss of water flow thru the valve.
5. Test the operation of the auto fill in the HOT operation mode.
