NOTE:
 The water heater shall be located so it is not subject 
to physical damage by moving vehicles or area fl ooding.
State of California
NOTE:
  The water heater must be braced, anchored, or 
strapped to avoid moving during an earthquake. Contact 
local utilities for code requirements in your area, visit 
http://www.dsa.dgs.ca.gov, or call 1-916-445-8100 and 
request instructions.
IMPORTANT:
 The water heater should be located in an 
area where leakage of the tank, connections, condensate 
lines or condensate will not result in damage to the area 
adjacent to the water heater or to lower floors of the 
structure. Due to the normal corrosive action of the water, 
the tank will eventually leak after an extended period of 
time. Also, any external plumbing leak, including those 
from improper installation, may cause early failure of the 
tank due to corrosion if not repaired.  If the homeowner is 
uncomfortable with making the repair a qualified person 
should be contacted.  A suitable metal drain pan should be 
installed under the water heater as shown below, to help 
protect the property from damage which may occur from 
condensate formation or leaks in the piping connections 
or tank.
 The pan must limit the water level to a maximum 
depth of 2-1/2 inches and be two inches wider than the 
heater and piped to an adequate drain. 
Locate the water 
heater near a suitable indoor drain. Outside drains are 
subject to freezing temperatures which can obstruct 
the drain line. The piping should be at least 3/4” ID and 
sloped for proper drainage. Under no circumstance will the 
manufacturer or seller of this water heater be held liable 
for any water damage which is caused by your failure to 
follow these instructions.

The water heater must NOT be placed on its side. It 
• 
should be transported and stored in an upright position.
Remove exterior packaging and place installation 
• 
components aside.
Inspect all parts for damage prior to installation and 
• 
start-up.
Completely read all instructions before attempting to 
• 
assemble and install this product.
After installation, dispose of/recycle all packaging 
• 
materials.
Location Requirements
Site location
Select a location near the center of the water piping system.  
The unit must be installed indoors and in a vertical position 
on a level surface. The fl ooring beneath the water heater 
must be able to support the weight of the water heater when 
fi lled with water (967 lbs. full). 
IMPORTANT:
 The water heater must be located in a space 
750 cubic feet or larger, and must have unrestricted airfl ow.  
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 effi ciency 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 2 feet in the front.
The water heater should be located in an area not 
subject to freezing temperatures. Water heaters located 
in unconditioned spaces (i.e., garages, basements, etc.) 
may require the water piping, condensate piping, and drain 
piping to be insulated to shelter against freezing. The drain 
and controls must be easily accessible for operation and 
service.
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, refrigerants, and many other commercial 
and household products. In addition, excessive dust and 
lint may affect the operation of the unit (See “Cleaning the 
Filter” section).  
The ambient air temperature must also be considered 
when installing this unit. In Effi ciency Mode the 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 and the heat pump does not operate.
NOTE
: Local codes and requirements in your area may 
require the installation of your water heater be accomplished 
in a way that the bottom element is elevated from the 
fl oor at least 18 inches.  Ensure that a platform capable of 
supporting the combined weight of the water heater and 
water (967-pounds) is used.
