The heat pump, water piping, pump, and hot water tank should
be located where the ambient temperature does not fall below
50°F [10°C]. Keep water piping lengths at a minimum. DO NOT
use a one way length greater than 50 ft. [15 m].
All installations must be in accordance with local codes. The
installer is responsible for knowing the local requirements,
and for performing the installation accordingly. DO NOT
connect the pump wiring until “Initial Start-Up” section, below.
Powering the pump before all installation steps are completed
will damage the pump.
Water Tank Preparation
1. Turn off power or fuel supply to the hot water tank.
2. Connect a hose to the drain valve on the water tank.
3. Shut off the cold water supply to the water tank.
4. Open the drain valve and open the pressure relief valve or
a hot water faucet to drain tank.
5. When using an existing tank, it should be
fl
ushed with
cold water after it is drained until the water leaving the
drain hose is clear and free of sediment.
6. Close all valves and remove the drain hose.
7. Install HWG water piping.
HWG Water Piping
1. Using at least 5/8” [16mm] O.D. copper, route and
install the water piping, valves and air vent as shown in
Figures 14, 15, or 16. An appropriate method must be
employed to purge air from the HWG piping. This may be
accomplished by
fl
ushing water through the HWG (as In
Figures 14 and 15) or by Installing an air vent at the high
point of the HWG piping system (as in Figure 16).
2. Insulate all HWG water piping with no less than 3/8”
[10mm] wall closed cell insulation.
3. Open both shut off valves and make sure the tank drain
valve is closed.

1. Close valve #4. Ensure that the HWG valves (valves #2
and #3) are open. Open the cold water supply (valve #1)
to
fi
ll the tank through the HWG piping. This will purge air
from the HWG piping.
2. Open a hot water faucet to vent air from the system until
water
fl
ows from the faucet; turn off faucet. Open valve
#4.

1. Open the cold water supply to

to bleed air from the HWG piping.
2. Open a hot water faucet to vent air from the system until
water
fl
ows from the faucet; turn faucet off.

3. Depress the hot water tank pressure relief valve handle to
ensure that there is no air remaining in the tank.
4. Inspect all work for leaks.
5. Before restoring power or fuel supply to the water heater,
adjust the temperature setting on the tank thermostat(s)
to insure maximum utilization of the heat available from
the refrigeration system and conserve the most energy.
On tanks with both upper and lower elements and
thermostats, the lower element should be turned down
to 100°F [38°C] or the lowest setting; the upper element
should be adjusted to 120-130°F [49-54°C]. Depending
upon the speci
fi
c needs of the customer, you may want to
adjust the upper element differently. On tanks with a single
thermostat, a preheat tank should be used (
fi
gure 16).
6. Replace access cover(s) and restore power or
fuel supply.
Initial Start-Up
1. Make sure all valves in the HWG water circuit are
fully open.
2. Turn on the heat pump and allow it to run for
10-15 minutes.
