Electrical Installation; Plumbing Installation - USECO AFCHCP Series Operation Manual

ELECTRICAL INSTALLATION

1. Refer to the nameplate. Verify the electrical
service power. Voltage and phase must
match the nameplate specifications.
Wiring the unit to the wrong voltage can
severely damage the unit or cause noticeably
decreased performance.
2. Available electrical service amperage must
meet or exceed the specifications listed on
the specification sheet provided with the unit.
Connect to the terminal block in the control unit.
wiring must be secured to the control unit with
an appropriate strain relief (provided by installer).
IMPORTANT:
*L1 to L2 must be 240 or 208 volts AC.
*L2 to Neutral must be 120 volts AC.
3. Tank and control must be connected to an
appropriate building ground. Ground
connection will always be marked.
NOTE: Wire gauge, insulation type and temperature
rating, as well as type, size and construction
of conduit, must meet or exceed applicable
specifications of local codes and of the
National Electrical Code.

PLUMBING INSTALLATION

NOTE: Plumb connections must be made in
Compliance with all Federal, State and
Local Plumbing Codes and Ordinances.
IMPORTANT: All drain plumbing must be
performed by a qualified plumber.
1. Install provided 1" drain valve on unit drain.
Plumb to an appropriate waste as required by
local plumbing and sanitation ordinances.
2. Install provided backflow preventer assembly to
the tank water inlet. Attach water outlet tubing
from 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 installed on a water line with
average pressure between 20 PSI and 90PSI. 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 control unit inlet fitting with a ¼" 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 ¼-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.
