Local Installation Regulations
This water heater must be installed in
accordance with these instructions,
local codes, utility codes, utility
company requirements or, in the
absence of local codes, the latest
edition of the National Electrical
Code.
It is available from some local
libraries or can be purchased from the
National Fire Protection Association,

Location
Minimum Air Temperature
Rheem Thermosiphon systems
must not be installed in areas
where the outside air temperature
can fall below 41°F continuously
for more than 18 hours. Where
outside air temperature falls lower
than 41°F Rheem closed loop
models must be installed. The
collector closed loop fluid is freeze
protected to -40°F.
If the outside air temperature is to
fall below 32°F for more than 4
hours on the Rheem closed loop
models, it is suggested that all
potable water plumbing is installed
with heat trace and insulated to
protect against pipe freezing. In the
event of a power failure, open a hot
water faucet and allow a slow
trickle of water to flow until power
is restored.
Please contact your service
technician for assistance and advice
with protection against pipe
freezing.

Inspect Shipment
Inspect the water heater for possible damage. Check the markings on the rating
plate of the water heater to be certain the power supply (Solar Electric Only)
corresponds to the water heater requirements. Make sure all parts included with
the solar water heater system are accounted for by comparing to the following
list of parts.
WARNING: Heat
trace will not protect
against pipe freezing in
the event of power loss.
!
WARNING: Extended
periods of cold weather,
including ambient air
temperatures below the
limits specified on the
right, may cause freezing
in exposed parts of the
system. It is the owner’s
responsibility to protect
the system in accordance
with these instructions if
the air temperature is
anticipated to approach
the specified limits.
