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.

 WARNING

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.

SCH Collectors Installation & Operation Manual

Lochinvar/TiSun Solar Thermal Collectors 
are not specifically designed for drain back 
installations.  Consult the factory if drain 
back utilization is necessary.

•  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.
