SCH Collectors Installation & Operation Manual
Installer – Read all instructions, including
this manual before installing. Perform
steps in the order given.
Have your collector(s) serviced/inspected
by a qualified service technician, at least
annually.
Failure to comply with the above could
result in severe personal injury, death or
substantial property damage.
When calling or writing about the collector
– Please have the collector model and
serial number.
Any claims for damage or shortage in
shipment must be filed immediately
against the transportation company by the
consignee.
Factory warranty (shipped with the
collector) does not apply to collectors
improperly installed or improperly
operated.

Introduction
(continued)
Before getting started on your installation be sure to carefully
read the preparation instructions in this section.
• You must comply with local
regulations, laws and standards of the
local governing authority.
• The frame must be capable of
withstanding the local snow and wind
loads and permit the correct
anchoring of the collectors in
accordance with all applicable local
regulations.
• The load bearing capacity of the
roofing and the frame shall be specially
checked or analyzed by a structural
engineer.
• The number of mounting brackets
specified by the Lochinvar/TiSun
manuals and parts sheets is based on
an average collector load bearing per
square foot. The maximum
permissible collector loading per
square foot may be calculated from the
number of mounting brackets, taking
into consideration the permissible
loading on the mounting brackets. If a
higher collector wind and snow loading
(including snow sliding off the roof)
per square foot is required, additional
mounting brackets will have to be
used. Roof pitches in excess of 30° also
represent increased loading; additional
mounting brackets must also be used
for this variant.

Lochinvar/TiSun Solar Thermal Collectors
are not specifically designed for drain back
installations. Consult the factory if drain
back utilization is necessary.
ƽ CAUTION
• The mounting substructure must be
capable of withstanding the local
snow and wind loads and permit
correct anchoring of the collectors.
• To avoid damage to the collectors
and mounting frames from snow
sliding off the roof, additional snow
guards must be placed in sufficient
numbers around the collectors and
above the collectors.
• The collectors must be linked with a
lightning arrester system and/or the
building’s ground system by a licensed
electrician.
•
Hydraulic connection of the collectors
must be performed according to
Lochinvar/TiSun specifications.
• The collector connections must not be
damaged, soiled or misaligned. Take care
during transport, installation, and
connection of the modules. Do not
remove the header protection caps at the
top and bottom connections of the
collector until just before installation.
• When connecting the modules to the
riser, the Hydraulic Connection Kit
(corrugated pipe) supplied must be
installed. Otherwise, the warranty is
invalidated.
•
Always connect the collector outlet and
inlet flow to each other diagonally,
please follow the connection
example (see FIG. 1-1 on page 6).
• Do not twist the headers when screwing
the connections together. Hold threaded
connection in the desired position and
tighten clamping ring union nut to
torque.
•
Roof penetrations for solar piping must
be adequately sealed against water ingress.
• Use only the original sensor well
supplied.
•
Use only high temperature and glycol
pipe sealing materials.
All piping should be properly insulated to
avoid freezing and/or burn potential.
