Households with small children, disabled, or elderly persons may
require a 120
o
F or lower temperature setting to prevent severe
personal injury or death due to scalding.
G. Water Temperature Adjustment
An ASSE 1017 rated mixing valve to avoid severe burns or death from
scalding temperatures IS REQUIRED PER SRCC OG-300.
E. High Temperatures
•
In sunlight, the copper plumbing ports can reach temperatures
in excess of 300
o
F. Thick leather gloves must be worn when
handling hot components to prevent serious burns.
•
Keep solar hot water system and components away from
children and animals.
•
In an installed, fully plumbed system, if the pump is stopped
in sunny conditions, the copper ports and piping can easily
reach temperatures in excess of 300
o
F. Caution should be
taken when handling such components.
•
Do not store combustible materials (dry leaves, tree branches,
gasoline, etc.) in the vicinity of the solar system.
Failure to follow these warnings could lead to property damage,
serious personal injury, or death.
F. Safety Precautions
•
Wear leather gloves when handling metal components and
hot plumbing components.
•
Adhere to safety regulations when working on roofs (or at a
height).
•
Always obtain engineer approval for installations in high wind
regions.
•
Assembly of the solar hot water system requires two persons
with the ability to lift 75 pounds each.
•
It is best to install the solar hot water system on a cool, cloudy
day.
•
Use of lead solder is expressly prohibited. Use of galvanized
steel, CPVC, PVC, PEX, or any other type of plastic pipe is
prohibited.
In addition, to prevent scalding, the high temperature of the potable
water must be limited using an ASSE 1016 tempering valve. This valve
is usually located between the hot water storage tank and faucets in
bathrooms, kitchens, etc. Tempering valves are mandatory under most
codes and usually set to a maximum of 120
o
F. Tempering valves must
be rated for high-temperature solar use.
H. System Water
Do not use petroleum-based cleaning or sealing compounds in a
solar water heating system. Gaskets and seals in the system may be
damaged. This can result in substantial property damage.
Do not use “homemade cures” or “patent medicines”. Damage to the
system, substantial property damage, and/or serious personal injury
may result.
I. Freeze Protection
NOTE:
Consider piping and installation when determining solar
collector location. Place the solar collector as close to the water heater
as possible.
Failure of the solar system or components due to freeze related
damage IS NOT covered by product warranty.
Part 2 - Important Information
A. Scope of this Manual
This manual pertains only to the installation and operation of the solar
collector. Details for the installation, operation, and maintenance of
the complete solar gas/electric water heating system, including, but
not limited to: the storage tank, gas/electric booster, pump, system
controller, valves, and other plumbing components, should be
provided separately by their respective manufacturers.
NOTE:
This manual is primarily a reference document for authorized
installation individuals, as the solar collector is not permitted to be
installed by non-authorized persons.
B. Local Standards and Authorized Persons
Installation must be completed in accordance with local standards
and regulations.
Installation must also be completed by a qualified tradesperson
who holds relevant industry licenses or certificates. The term
“authorized person(s)” used throughout this document refers to a
suitably qualified professional. Unless otherwise specified, no part
of the solar collector may be inspected, repaired, or maintained by
anybody other than an authorized person.
C. Terminology
Solar terminology differs from region to region. To avoid confusion,
please note the following:
Supply
– The plumbing line running from the outlet of the collector
to the tank.
Return
– The plumbing line running from the tank (or heat
exchanger) to the inlet of the collector. This line incorporates the
circulation pump.
D. Possible System Designs
1. Open Loop Systems
An open loop system has potable water circulating through
the solar collectors. Open loop systems are recommended for
hot or warm climates that rarely freeze. For rare incidents when
