WATTERSAVER™ HEAT PUMP WATER HEATER
4
IMPORTANT:
The water heater shall be located so it is
not subject to physical damage by moving vehicles or
area flooding. (Figure 1)
All condensate drain lines and T&P valve drains must be
piped separately and routed to an adequate drain. To pro-
tect the WatterSaver’s outer finish, do not pipe drain lines
into the drain pan.
Failure to follow the instructions in this installation,
operation, and maintenance manual will release the
manufacturer from any liability for any water dam-
age in connection with this water heater.
2. Use a ¼” nut driver to loosen the screws around the
base of the shroud and remove it from the water heater. it
is not necessary to remove the screws as the holes in the
base of the shroud are slotted.
3. Remove the screws from the shroud and separate the
halves.
4. Install plumbing to the tank. Ensure plumbing connec-
tions will allow the installation and removal of the shroud
after all plumbing is complete (See “Water system Pip-
ing”).
5. Install primary and secondary condensate drain lines
to the evaporator pan and route to an adequate drain.
(Figure 2)
6. Ensure the toggle switch on the control board (see “re-
placement parts list” on page 16 for location ) is in the
“HP” position. (In the “ELEC” position, the heat pump sys-
tem is disabled and the unit will operate as an electric
resistance water heater ONLY.)
7. Connect wires L1, L2, and Ground to the electric box
located in front of the evaporator coil on top of the tank.
8. Replace the shroud and ensure wires L1, L2, and
Ground pass through the opening in the top of the shroud.
WATER SYSTEM PIPING
Water piping, fittings, and valves must be properly in-
stalled for the correct and safe operation of the
WatterSaver
TM
Heat Pump Water Heater. Please note
the following:
• DO NOT Install the water heater with piping that
is unsuitable for drinking water (iron piping, PVC
piping, or piping that has been treated with
chromates, boiler seal, or other chemicals). Use
only new piping such as copper, CPVC, or
polybutylene.
• DO NOT Add any chemicals to the piping which
could contaminate the water supply.
• DO NOT Use any type of pump, valve, or fitting
that is unsuitable for potable water.
• DO NOT Install check valves in the cold water
supply to the unit.
• DO NOT Use valves that excessively restrict wa-
ter flow. Use only full flow or gate valves.
• DO NOT Use any lead-based solder in potable
water lines. Use 95/5 tin-antimony or another suit-
able non-lead solder.
