Page 7: Roof Kit Sizing
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. -

Attaching the Connection Kit Step Eight (return connection) 1.Assemble and connect end fittings (Male connection A, T connection G & Air bleeding valvue E) 2. Open lid on left hand end tube fitting 3. Place rubber seal (D) on male end of collector area (blocking upper chamber) 4.Secure in position with clip (F) Qty. - Page 12 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.

Page 13: Pump Station
Pump Station The Kingspan Solar 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. -
Page 14: Safety Vessel Connections
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 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. -
Page 15: Wiring The Control Panel
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. - Page 16 Varisol Installation Manual 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.

Page 17: Commissioning The System
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. -

Page 20: Servicing And Maintenance
Varisol Installation Manual 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. -
