REMARKS
A solar collector generates heat
from sunlight and all other types
of light. This leads to collector con-
nectors getting very hot, even when
they are not lled. This creates a
risk of burning. Cover the collec-
tors with opaque material until the
installation has been completed. It
is recommended you leave the col-
lector inside its packaging until it is
installed.
Never install any shut-o valves in
the line between the collectors and
the safety valve. The safety valve re-
sponds at 87 PSI pressure.
Never set the Solar loop presure
greater then potable pressure.
Neither drop the collector nor any-
thing onto the collector.
Never step onto or stand on the col-
lector.
Never leave the collector unsup-
ported or unsecured. The glass
could break if the collector falls over.
All sensor wiring needs to be rated
for expected temperatures. All sen-
sor wiring needs to be protected
from degradation and false signals.

SAFETY INSTRUCTIONS
Installation & Transportation
Solar Collectors must be secured during transportation. You must secure the collectors from falling out of
the packaging, and from scratching each other.
• Use of a carrying strap is recommended
• Do not lift the collector by the connection ports or header tube
• Avoid impacts & vibration on the collectors as much as possible
• Please lift collector by lifting lugs (if included)
On Roof Operation
Please follow the following safety & operational guidelines when installing Solar Collectors
• Included Mounting Hardware(2 x antislip protection and 4 x side bracket) is intended for
On Roof Installations Only
• Additional Mounting Hardware is needed for Pitched Roof & Tilt Mount Installations
• You will be intervening in existing roof and roof coverings during installation
• Please ensure that proper measures are taken for protection of all installation crew
• Familiarize yourself with local laws & regulations, and follow them carefully
Important Note - Solar Collectors should not be lled when the sun is out because scalding can occur
due to steam being released from the system. If you must ll the Solar Collectors during sunny periods,
please cover the collectors.
Lightning Protection
Solar Collectors should be electrically connected to each other, and to the building’s Earth ground via the
shortest possible route. An authorized lightning protection specialist should be consulted to examine the
installation and installation site.
