Heat Recovery Package
HEAT RECOVERY PACKAGE
The Heat Recovery package is a factory mounted option.
It consists of a forced pumped unit that employs a
circulating pump to move water through a double wall/
vented heat exchanger and returns the heated water to
the water tank. The water is heated by superheated
refrigerant discharge gas from the compressor. This
waste heat of the cooling mode captured by the heat
recovery increases the capacity and efciency of the
heat pump unit. If the air temperature is uncomfortable
coming from the air vents in the heating mode the heat
recovery may need to be turned off. In the heating mode
the heat recovery captures heat that would normally be
used for space heating.
If heat recovery unit is installed in an area where
freezing may occur, the unit must be drained
during winter months to prevent heat exchanger
damage. Heat exchanger ruptures that occur due
to freezing will void the heat recovery package
warranty along with the heat pump warranty.
TYPICAL CONNECTION PIPING
HEAT RECOVERY PACKAGE
WATER TANK PREPARATION:
1. Turn off electrical or fuel supply to the water heater.
2. Attach garden hose to water tank drain connection
and run other end of hose out doors or to an open
drain.
3. Close cold water inlet valve to water heater
tank.
4. Drain tank by opening drain valve on the bottom
of the tank, then open pressure relief valve or
hot water faucet.
5. Once drained the tank should be ushed with
cold water until the water leaving the drain
hose is clear and free of sediment.
6. Close all valves and remove the drain hose.
7. Install HR water piping.
HR WATER PIPING:
All hot water piping should be a minimum of 3/8t O.D.
copper tube to a maximum distance of fteen (15)
feet. For distances beyond fteen feet but not
exceeding sixty (60) feet use 1/2” copper tube.
Separately insulate all exposed surface of both
connecting water lines with 3/8” wall closed cell
insulation. Install isolation valves on supply and return
to the heat recovery.
WATER TANK REFILL:
1. Open the cold water supply to the tank.
2. Open a hot water faucet to vent air from the
system until water ows from the faucet, then
close.
