However a supplementary heating system such as oil or gas boiler, heat pump or wood boiler is required for months which have less solar radiation. For large systems, Kingspan provide a system design service to its Accredited Installer Network and technical design consultants. Please visit www.kingspansolar.com to locate an Accredited Installer or distributor in your area.
Important Pre Installation Information Sizing of safety equipment Expansion vessel sizes are relative to the volume of liquid in the system. Therefore it is important that the Thermomax ‘Technical Design Guide’ is consulted for each system. Pipe Sizing (minimum of 15mm diameter pipework must be used) Pressure Drop - Tyfocor LS Collector Pipe External Area...
Roof Kits Standard Roof Fixings The Varisol product range is available with a choice of roof fixing options to suit many roof types, see diagram below for the most common fixings. Roof fixings are available for slate, tiled, double lap plain clay, metal seam and concrete. For others please contact Kingspan.
Roof Kit Sizing The modular design of the Varisol collector means that any number of tubes can be assembled to make up the required collector size. Since the mounting kit cross rails are only supplied in 10, 20 and 30 tube sizes it is necessary to cut the rails to length if an intermediate sized collector is required.
Varisol Installation Manual Collector Assembly - Sloping Roof Fixing the rails Step One 1. Refer to mounting kit sizing on page 5 for bracket seperation 2. A ttach brackets (C) to roof using M8x50 coachscrews (E) 3. S ecure side rails (A) to lower brackets using M10x65 bolt assy Step Two 1. From upper end of each side rail, slide 2 M8x16 bolt into position...

Attaching Support Rails Step Three 1. Refer to mounting kit sizing on page 5 for support rail lengths 2. S lide 2 M8 bolts into lower face of each support rail (B) 3. Attach 90° bracket (G) in 4 places using M8 nuts & washers at locations illustrated 4. Attach upper and lower support rail to 90° bracket as shown below 1500mm 100mm 1400 – 1700mm 400 – 600mm (10) 600 – 1000mm (20) 800 – 1400mm (30) Installing the first tube Step Four 1. A lign first tube with end of support rail and push home by clicking into rail (push on upper push point only) 2. A lign lower tube support clip into rail and push home by clicking into rail (push on lower push point only)
Varisol Installation Manual Installing additional tubes 50˚ Step Five 1. Rotate second tube approximately 50° to first tube, using arrow symbols on plastic enclosure for guidance 2. Firmly insert male fitting of second tube to female connection of first tube, ensuring o-ring protection is removed first.
Attaching the Connection Kit Step Eight (return connection) 1. A ssemble and connect end fittings (Male connection A, T connection G & Air bleeding valve E) 2. Open lid on left hand end tube fitting 3. Place rubber seal (D) on male end of collector area (blocking upper chamber) This applies to DF only - please discard seal for HP 4. S ecure in position with clip (F) Qty. Tubes DF ONLY 5. Ensure clip (F) legs protrude out of bottom of enclosure 6. C omplete and attach technical label (I) 7.

Varisol Installation Manual Connection Information In any solar panel system, the ‘return’ refers to the intake in the collector where liquid is returning to be reheated. The ‘flow’ refers to the collector side where the liquid is flowing to the heat exchanger.
Pump Station The Kingspan Solar product range offers both a single stream and a dual stream pump station. Each pump station is available in various sizes to suit the required flow rate of the system. The flow rate required on a system is typically 1 litre per minute, per square metre installed for systems up to 12m².
Varisol Installation Manual Safety Vessel Connections Pressure Relief Valve (PRV) Rated at 6 bar, the PRV may discharge heat transfer fluid (Tyfocor® LS) which must be channelled into a solar discharge vessel, capable of withstanding high temperature discharge and containing the total collector volume. The container should be secured so it cannot be removed or spilled.
Wiring the Solar Control Panel All electrical aspects of the installation should be undertaken by a qualified electrician. Note that for safety, the pump and sensor connections should always be wired prior to connecting power to the solar control panel. IMPORTANT: The solar control panel must have a permanent electrical power supply which must not be interrupted either manually or with a time switch.

Commissioning the System The evacuated tubes should be installed at a time when there is very low light such as late afternoon when the sun is low and not particularly strong. Alternatively the tubes should be covered. This is important as tube connections can heat up considerably in a short space of time and have potential to cause injury even if the glass temperature remains cool.
• Disconnect pipes from the manifold to disengage. • Repeat process until all tubes are removed. Disposal Dispose of separate materials in accordance with local regulations. Please see the following pages for details of materials used in the construction of Varisol collectors and guidance on disposal of antifreeze.
Varisol Installation Manual Disposal of Solar Anti-Freeze Solution The solution we supply with our solar systems is a thermal transfer fluid based on 1,2 propylene glycol and water. The solution also contains corrosion inhibitors and has been specifically designed for used in solar systems with elevated temperatures, such as those experienced with Vacuum Tube Collectors.
