State HPWH Inlet/Outlet Duct - Manual (Page 2)

Kit contains: (1) Assembled Inlet Duct Adaptor 323498-000 or
(1) Assembled Outlet Duct Adaptor 323497-000
Tools required: #2 Phillips screwdriver, wire cutters, scissors.
Supplies needed: 8” insulated flex duct, duct clamp or strap,
appropriate duct termination and duct tape
Important: Use only factory authorized replacement parts. If
you lack the necessary skills to properly perform the instal-
lation, you should not proceed, but get help from a qualified
service technician.
Prior to installing the Duct Adaptor
1. Press the power button on the User Interface Module (UIM)
to place the water heater in Standby Mode (Figure 1).
Note: Power to the board is still present at this time.
2. Remove all power to the unit at the breaker/fuse panel prior
to removing any panels.
Installation of the Duct Adaptor:
1. If installing the Inlet Duct Adaptor remove the screws from
the left louvered access panel of the unit. If installing the
Outlet Duct Adaptor remove the screws from the right lou-
vered access panel (Figure 2).
NOTE: These Adaptors are not interchangeable.
2. Using the eight (8) screws removed earlier attach the new
Duct Adaptor panel to the top shroud of the unit. The new
Duct Adaptor panel should be oriented with the louvered
portion of the panel located at the bottom of the panel to
ensure that the panel lines up with the existing holes (Fig-
ure 3)
Installation of the Ductwork:
1. After the desired length of duct has been determined (maxi-
mum 10 feet*), carefully cut completely around and through
the duct insulation with a pair of scissors.
2. Using a pair of wire cutters, cut the wire inside the core
duct. Fold the insulation jacket back away from the core
duct (Figure 4).
3. Slide at least 1” of the core duct over the ducting adaptor lip
and seal with at least two (2) wraps of duct tape. Addition-
ally, secure the core duct with a band clamp or duct strap
placed over the ducting adaptor and tape (Figure 5).
4. Slide insulation back over the duct core and the lip of the
inlet duct adaptor. Use duct tape to secure the insulation to
the inlet duct assembly (Figure 6).
5. Add support to the duct work as necessary or as required
by local codes. Special attention must be given to prevent
large droops in the duct work which could allow moisture to
pool.
6. The appropriate duct termination shall be added to the
termination end of the duct. This termination shall prevent
any debris or rodents from entering the duct work and shall
minimally restrict the airflow through the ducting. In addi-
tion the termination shall be designed to prevent rain from
entering into the duct work if terminated to the outside.
Restoring Operation:
1. Restore power to the water heater at the breaker/fuse
panel. Press the power button on the UIM (Figure 1).
2. Follow the Operating Your Water Heater section found in
the Installation Instructions and Use and Care Guide for
restarting your heat pump water heater.
3. Check the UIM for any errors and correct accordingly.
