The heat pump, water piping, 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 100 ft. (one way) [15
m]. See Table 6 for recommended piping sizes and maximum
lengths.
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
turn the hot water mode “ON” until “Initial Start-Up” section
below is complete. Engaging the hot water mode before all
installation steps are complete will damage the unit.
DHW Water Piping
1. Using at least 3/4” [12.7mm] I.D. copper, route and install
the water piping and valves as shown in Figure 18. Install
an approved anti-scald valve if the the hot water set
point is set above 125°F. An appropriate method must
be employed to purge air from the DHW piping. This
may be accomplished by flushing water through the heat
pump or by installing an air vent at the high point of the
DHW piping system.
2. Insulate all DHW water piping with no less than 3/8”
[10mm] wall closed cell insulation.
3. Make sure the tank drain valve is closed.
4. Check the union connections on the DHW pump to
ensure they are tight before filling system.
Water Tank Refill
1. Close valve #4. Ensure that the DHW valves (valves #2
and #3) are open. Open the cold water supply (valve #1)
to fill the tank through the DHW piping. This will force
water flow through the DHW heat exchanger and purge
air from the DHW piping.
2. Open a hot water faucet to vent air from the system until
water flows from faucet; turn off faucet. Open valve #4.
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. Replace tank access covers and apply power to the
storage tank.
Initial Start-Up
1. Make sure all valves in the DHW water circuit are
fully open.
2. Turn on the heat pump hot water mode by enabling
operation in the user menu. Make sure the hot water set
point is above the hot water temperature. The heat pump
should begin to operate in the hot water mode. You can
also enable heat pump hot water mode through manual
operation in the myUplink Pro app or Service tool.
3. Allow the unit to run a few minutes to stabilize. The
temperature difference between the entering potable
water and leaving potable water should match the
temperature differential set for the DHW Pump
Configuration.

⚠
CAUTION!
⚠
CAUTION! Use only copper piping for DHW piping due to
the potential of high water temperatures for water that has
been in the DHW heat exchanger during periods of no-flow
conditions (DHW pump not energized). Piping other than
copper may rupture due to high water temperature and
potable water pressure.
