Water Heater Location Condensate Drain Line
[] Centrally located with the water piping system.
[] The flooring beneath the water heater must be able to
support the weight of the water heater when filled with
water (See Table 1).
[] Located indoors (such as a basement or garage) and in
a vertical position. Sheltered from freezing temperatures.
[] Provisions made to shelter the area from water
damage. Metal drain pan installed and piped to an adequate
drain.
Sufficient room to service the water heater.

[]
Sufficient air for the heat pump to function. The water
heater must be located in a space 750 cubic feet or
larger, and must have unrestricted airflow. As an
example, a room that has an 8 foot tall ceiling and is 10
feet long by 9-1/2 feet wide would contain 760 cubic feet.
NOTE: For optimal efficiency and serviceability, the
following clearances should be maintained: 3 feet on the air
inlet side, 5 feet on the air outlet side, 6 inches in the back,
and 2feet inthe front.
The unit cannot be placed into any type of closet or small
enclosure.
The site location must be free from any corrosive elements
in the atmosphere such as sulfur, fluorine, and chlorine.
These elements are found in aerosol sprays, detergents,
bleaches, cleaning solvents, air fresheners, paint, and
varnish removers, refrigerants, and many other commercial
and household products. In addition excessive dust and
lint may affect the operation of the unit and require more
frequent cleaning (See "Routine Preventive Maintenance"
section).
Ambient air temperature must be above 45°F and below
109°F. If the ambient air temperature falls outside these
upper and lower limits the electrical elements will activate
to meet the hot water demand.
Water System Piping
[] Temperature and pressure relief valve properly
installed with a discharge pipe run to an adequate drain
and sheltered from freezing (See Figure 10).
[] All piping properly installed and free of leaks.
[] Heater completely filled with water (See "Water Piping
System" section).
[] Closed system pressure buildup precautions installed (See
"Closed System/Thermal Expansion" section).
[] Mixing valve (when applicable) installed per manufacturer's
instructions (See "Temperature Regulation" section).
[] Must be located with access to an adequate drain or
condensate pump.
[] Condensate drain lines installed and piped to an adequate
drain or condensate pump (See Figure 9).
Electrical Connections
[] This water heater requires a 240 VAC single phase 25 amp
power supply. DO NOT use a 208 VAC service.
[] Wiring size and connections comply with all applicable
codes or inthe absence of local or state codes follow NFPA-
70, the National Electrical Code-current edition.
[] Water heater and electrical supply are properly
grounded.
[] Wiring enclosed in approved conduit (if required by local
codes).
[] Proper overload fuse or circuit breaker protection installed.
Post Installation Review
[] Understand how to use the User Interface Module to set
the various modes and functions (See "Adjusting the User
Interface Module/Operating Modes" section).
[] Hybrid Mode is the recommended Operating Mode.
Understand the various Operating Modes and which mode
may be best based on season, ambient temperature,
and usage (See "Operating Mode Description" section).
NOTE: It may be necessary to temporarily change modes
if for example filling a spa or hot tub.
[] Understand the importance of routine inspection/
maintenance of the condensate drain pan and lines
(See "Inspection/Cleaning of the Condensate Drain
Pan & Condensate Drain Lines" section). This is
to help prevent any possible drain line blockage
resulting in the condensate drain pan overflowing.
IMPORTANT: Water coming from the plastic shroud is
an indicator that both condensation drain lines may be
blocked. Immediate action is required.
[] To maintain optimal operation check, remove and clean the
air filter (See "Air Filter Cleaning/Replacement" section).
[] The Installation Instructions and Use & Care Guide should
be kept with the water heater for reference.
