• 

Centrally located with the water piping system.

• The 

fl ooring beneath the water heater must be able 

to support the weight of the water heater when 
fi lled with water (see Table 1).

• 

Located indoors (such as a basement or garage) 
and in a vertical position. Protected from freezing 
temperatures.

• 

Provisions made to protect 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 
approximate minimum air requirement is 750 
cubic feet of space.  For example: this would be 
a room approximately 10’X9 1/2’ in size with an 8’ 
ceiling.  NOTE: For optimal effi ciency, the following 
minimum clearances should be maintained: 3 ft. on 
the air inlet side, 6 ft. on the air outlet side and 2 ft. 
front and back. 

• Unrestricted 

airfl ow, 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, fl uorine, 
and chlorine. These elements are found in aerosol 
sprays, detergents, bleaches, cleaning solvents, 
air fresheners, paint and varnish removers, 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 “Cleaning/Replacing the Air Filter” 
section (p.11).

• 

Ambient air temperature must be between 45°F 
and 109°F (inclusive) in order for the heat pump to 
work properly. If the ambient air temperature falls 
outside these upper and lower limits the electrical 
elements will activate to meet hot water demand.

• 

Temperature and pressure relief valve properly    
installed with a discharge pipe run to an adequate 
drain  and protected from freezing.

• 

All piping properly installed and free of leaks.

• 

Heater completely filled with water, see “Water 
Piping System” section (p.9).

• 

Closed system pressure buildup precautions 

installed, see “Closed System/Thermal Expansion” 
section (p.10).

• 

Mixing valve (when applicable) installed per 
manufacturer’s instructions see “Water Piping 
System” (p.9).

• 

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.

• 

The water heater requires nominal 240 VAC for 
proper operation.

• 

Wiring size and connections comply with all 
applicable codes or in the 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).

• 

Dedicated circuit with proper overload fuse or 
circuit breaker protection installed.

• 

To maintain optimal operation check, remove and 
clean the air filter see “Cleaning/Replacing the Air 
Filter” section (p.11).

• 

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” (p.46). 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. 

• 

Understand how to use the User Interface Module 
to set the various modes and functions, see 
“Adjusting the User Interface Module/Operating 
Modes” (p.12-13). 

• 

Understand the various Operating Modes and 
which mode may be best based on season, 
ambient temperature, and usage see “Operating 
Mode Description” (p.12-13). NOTE: It may be 
necessary to temporaily change modes if, for 
example, filling a spa or hot tub.

• 

The Installation Instructions and Use & Care Guide 
should be kept with the water heater for reference.
