In order to completely protect the integrity of the
solar collector and piping, the system is designed to
be drained manually if subject to extended periods
of disuse or persistent hard freeze conditions below
minus 30° Fahrenheit. (See Sections 8.1 and 8.2
below).
3) INSTALLATION REQUIREMENTS -
GENERAL
3.1 The contractor shall obtain all required permits
and approvals.
3.2 The installation shall conform to all federal, state
and local regulations, codes, ordinances and standards
governing solar water heating system installations,
and the contractor shall adhere to sound building
safety and trade practices. Special consideration
must be given to building code requirements for
the penetration of structural members and re rated
assemblies.
3.3 The solar collector must be located in a
structurally sound area of the roof that will be
unshaded for the majority of the day all year round.
Adjacent buildings and trees should be checked for
possible winter shading. An instrument such as the
Pathnder can be used for solar site analysis.
3.4 Before the installation the contractor shall inspect
the condition of the roof and notify the homeowner
of any existing roof damage or necessary repairs.
3.5 The homeowner and contractor shall conrm the
location of all roof and ground mounted components
in advance of the installation.

The Dowfrost HD HTF protects your SolaRay solar
system against freezing. Dowfrost HD can pro-
vide reliable freeze protection at temperatures as
low as minus 60° Fahrenheit if properly applied
and maintained. Use of uninhibited propy-
lene glycol, plain water or a concentration
of these two fluids as the HTF in this system
is strictly prohibited.
Propylene glycol can degrade over time. The
process of degradation is accelerated in presence
of oxygen and/or heat. We strongly encourage
you to establish a preventative maintenance
schedule with your installation contractor. The
HTF pH level must be maintained between 8 and
10 in order to prevent glycol oxidation and cor-
rosion of the collector piping. SunEarth’s col-
lector warranty specifically excludes freeze
damage for any reason and absorber plate
damage resulting from the oxidation of the
propylene glycol HTF.
