lp-220 Rev. 000 Rel. 007 Date 2.12.18
4
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.
D. Evacuated Tubes
Be careful when handling the evacuated tubes, as they will break if
knocked heavily or dropped.
E. High Temperatures
•
In sunlight, the copper plumbing ports can reach temperatures
in excess of 392
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 320
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
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
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.
If exposed to sunlight, hot, and have internal pressure built up, the
tubes may explode rather than implode if knocked and broken. This
is a rare occurrence, but safety precautions should be taken. To avoid
personal injury, wear safety glasses and leather gloves at all times
when handling evacuated tubes.
When installed, evacuated tubes may break if struck by a hard object
with enough force (e.g. a branch falling on the roof). During installation,
consideration should be taken as to the possible path any broken glass
may take. Where possible, protection should be provided to prevent
broken glass from reaching ground level where somebody could walk
on it.
THE INSTALLER SHOULD MAKE THE HOMEOWNER AWARE OF THE
SOLAR COLLECTOR LOCATION AND THE POSSIBLE VICINITY OF
BROKEN GLASS IN THE EVENT OF AN EXTREME STORM OR HEAVY
OBJECT FALLING ON THE COLLECTOR.
•
Always wear safety glasses when handling evacuated tubes.
•
Wear thick leather gloves when handling metal components
and hot plumbing components, including hot heat pipes.
•
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 50 pounds each.
•
It is best to install the solar hot water system on a cool, cloudy
day.
•
Store evacuated tubes in dark or shaded places until insertion
into the manifold.
•
Use of lead solder is expressly prohibited. Use of galvanized
steel, CPVC, PVC, PEX, or any other type of plastic pipe is
prohibited.
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.
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.
