SCH Collectors Installation & Operation Manual
Before getting started on your installation be sure to carefully read the preparation instructions in this section.
WARNING
NOTICE
CAUTION
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.
• 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 in 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.
CAUTION
CAUTION
CAUTION
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.
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.

SCH Collectors Installation & Operation Manual
WARNING
What to avoid
• Only loosen the crane connection when the collectors are completely fixed to the substructure.
• Pay special attention to roof-work near an electric grid. If need be, the constructor must take security precautions such as isolation, covering, etc.
Inspect the roof surface in the area of the installation for cracks, water leakage, and roofing material quality and uniformity. This is especially important if the roof is more than 10 years old.
Inspect the roof for sags and other abnormalities. A sag or deep depression in the roof may indicate a structural weakness in the support system that may require correction.
• Check that all rafters, trusses and other materials are in good condition.
WARNING
• Avoid rotating movements of the load through wind. Secure load
CAUTION
before lifting.
• Only move collectors on the given fixing loops.

3 Roof Attachment Installation (continued)
Installation of roof attachment types
The solar thermal collectors are capable of being mounted to several different types of roofing with a wide variety of mounting hardware available from Lochinvar.
Double hanger bolt for universal fastening #SRM20001
Universal fixture for parallel and inclined installation on various roof types and freestanding installation on sufficiently anchored frames. Two hanger bolts are to be installed on the roof as vertically as possible with a spacing of 4 3/4" to 6 3/4". The two are connected by an intermediate plate.
CAUTION
The hanger bolt must be screwed into a support capable of bearing the required static load (generally rafters).
Install the hanger bolt using a field supplied anchoring adapter.
• The roofing must be capable of withstanding the pressure needed to compress the gasket.
Beware of linear expansion in sheet metal that prevents a linear expansion and can cause lifting of the sheet.
Unpacking and checking parts
When unpacking the system, check the model names of the components of each system and check to be sure you have the correct number of parts (see FIG. 3-2).
Figure 3-2 Kit #SRM20001 - Double Hanger Bolt Kit Components
