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.
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) Varisol Pressure Drop - Tyfocor LS Collector Pipe External...
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 should an intermediate sized collector be required.

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. Note: It is essential that the collector temperature sensor is located in the flow of the collector.
Varisol Installation Manual Pump Station The Kingspan Solar Thermomax product range offers both a single stream and a dual stream pump station. Each pump station is available in two flow rates, 2-12 litres/minute and 8-28 litres/minute. The flow rate required on a system is typically 1 litre per minute, per square metre installed.
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 container capable of withstanding high temperature discharge and containing the total collector volume. The container should be secured so it cannot be removed or spilled.
Varisol Installation Manual 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.

Connection of first output/pump (R1) R1 of the SC controllers comprises a semiconductor relay (TRIAC), also suitable for RPM control with a maximum switching current displayed on the unit type plate. Both the SC100 and the SC200 contain an electromechanical relay, R2. Note that the SC300 contains two RPM relays, R1 and R2 as well as an electromechanical relay, R3.
Varisol Installation Manual 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.
• Unclip rubber retainer on the tube support • Remove sensors and associated cables • Slide the Varisol removal slide along the • Remove earthing cables manifold support rail strating at the right hand end.
Servicing and Maintenance Users should regularly check the temperatures which the solar control panel is recording. With the SC range of controllers, simply pressing the ‘SET’ button on the fascia once will display the upper and lower collector temperatures since the control panel was last reset. If the collector temperatures have been excessively high i.e.
