Location Requirements

Site location
Select a location near the center of the water piping system.
The solar storage tank water heater must be installed indoors
and in a vertical position on a level surface.
The solar storage tank water heater should be located in an
area not subject to freezing temperatures. Solar storage tank
water heaters located in unconditioned spaces (i.e., attics,
basements, etc.) may require the water piping and drain piping
to be insulated to protect against freezing. The drain and
controls must be easily accessible for operation and service.
Keep combustibles such as boxes, magazines, clothes, etc.,
away from the solar storage tank water heater area.
This solar storage tank water does not have suffi cient
capacity for use with a spa or hot tub.
NOTE: Local codes and requirements in your area may
require the installation of your solar storage tank water to
be accomplished in a way such that the bottom element is
elevated from the fl oor at least 18 inches.
IMPORTANT: The solar storage tank water should be located
in an area where leakage of the tank or connections will not
result in damage to the area adjacent to the solar storage tank
water 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 owner/
operator is uncomfortable with making the repair a qualified
person should be contacted. A suitable drain pan should be
installed under the solar storage tank water 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 drain 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 solar storage tank
water 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 pitched for proper
drainage. Under no circumstance will the manufacturer or
seller of this solar storage tank water be held liable for any
water damage which is caused by your failure to follow these
instructions.

so it is not subject to physical damage by moving vehicles
or area fl ooding.
