• 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

￿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,soiledormisaligned. Takecare 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.

(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.

￿CAUTION All piping should be properly insulated to avoid freezing and/or burn potential.
