SLV/SLH 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 collector 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.

 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 examples (see FIG.’s 1-2 and 1-3 on page 6).

• Insert the brass support sleeve in the copper pipe before fixing the clamping ring threaded connection.

• 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.

 WARNING

Transportation device

• The SL transportation device is only suitable for Lochinvar/TiSun SLV and SLH collectors.

• Note clamp positions for manual and crane installation

• Examine transportation device and clamp for correct seating and good grip before lifting the collectors. Tightening torque for star knob is 11 ft./lbs.

• Collector installation by two (2) persons requires four (4) transportation devices (2 sets)

• Collector installation by crane requires two (2) transportation devices (1 set)

• General local installation and safety regulations and laws apply for installation by person or cranes.

• Installation of LOCHINVAR/TiSun SLV/SLH collectors are only allowed for qualified installer.

• Local instructions, laws and standards are to be followed.

• Collectors are to be located so falling snow and ice will not endanger any person or property.

• Use personal protection equipment (helmet, belt, security shoes) when on the roof.

• Secure tools and materials against fall.

• It is forbidden to stand or walk under a hanging load.

• Danger area has to be restricted.

• Avoid rotating movements of the load through wind. Secure load before lifting.

• Use ladders properly and check stability.

 CAUTION

• Only loosen the crane connection when the collectors are completely secured to the substructure.

• Pay special attention to roof work near an electric grid. If need be, the installer must take security precautions such as isolation or covering of electrical devices.

• 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 suitable condition.

NOTICE

What to avoid

 CAUTION

• See FIG. 2-9 for crane transportation connection points and positioning.

• Collectors are to be located such that eventual sliding of snow and ice does not endanger any person.

• The collectors have a large surface exposed to wind. Therefore, be aware of possible wind hazards when using a crane for installation (the collector may flip over quickly). In this case immediately stop the crane operation and protect the collector against swinging (hazard of collector breakage).

Rafter anchor for standard and tall roof tiles #SRM20003 & #SRM20004

The rafter anchor is used for parallel and inclined mounting on tiled roofs with a roof pitch of at least 15° and an area loading greater than 6 lb/ft2. Can be used for various types of roofing tiles.

 CAUTION

• The anchors must be screwed into a support capable of bearing the required static load (generally rafters or concrete).

• Complies with the requirements of DIN1055.

• Roof batten height at least 1".

• The gap between rafter anchor and top edge of the tile must be at least 3-5mm. Under no circumstances may the rafter anchor be in contact with the tile (if the overall height of roof batten and tile do not match, the lower height must be packed out).

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. 3-15).

Install rafter anchor

1. Determine roof type. Inspect the structural integrity of the roof and the durability of the roof materials.

2. Determine the number of collectors needed for the installation and the number of required roof attachments from Table 3B or 3C on page 11.

4. Number two (2) tiles, one above the other. The upper tile will be removed to install the rafter anchor.

5. Mark the edge of the upper tile on the lower tile to ensure proper alignment upon assembly.

6. Using the rafter anchor as a template, pre-drill two (2) 6 mm holes, approximately 4 inches deep into the roof substructure (see FIG. 3-16), perpendicular to the roof.

7. To achieve the recommended 3 - 5 mm clearance above the tile, place spacer plate(s) (provided in the kit) between the rafter anchor and the roof substucture if necessary (FIG. 3-17).

8. Place the rafter anchor on the spacer plate (if used).

9. Place the heavy duty washers over the holes pre-drilled in Step 6.

10. Install the wood screws through the washers and rafter anchor into the roof substructure.

Note: It may be necessary to grind the upper tile to assure a better fit (FIG. 3-18).

Tiled roof hook #SRM20016

The tiled roof hook is only used for the mounting of collector modules parallel to the roof line (SLV and SLH) on tiled roofs with a roof pitch of at least 15°. The hooks are hung over the tiles. Should the underlying roof batten be too thick, the lower part of the top hook is cut off. To ensure that the hook cannot be lifted, a hole is drilled through the tile and the hook held by the screw provided in the kit.

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. 3-19).
