You will have to provide all pipework, fittings and insulation. The following specifications are required for items provided by the

installer:

pipework:

This should be 15 mm or 22mm copper or flexible stainless on both flow and return, depending on number of solar

collectors and pipework (see Frame 4). Plastic pipework is not suitable for the temperature extremes possible in solar circuits. Pipe

clips must withstand the temperatures of up to 200°C. (We recomend annular twin pipes PART No’s. 206519 - DN16x15m long &

206520 - DN20x15m long). A first fix kit is provided with each solar pack. This comprises flexible through roof hoses (insulated)

one metre in length, collector panel angle couplings with fibre seals and a separate solar controller flow sensor.

fittings:

Brass olive compression fittings must be used . Unleaded solder is not designed for solar circuits. Alternatively, high

performance crimped fittings or similar performance fittings can be used. Teflon or similar type tape is not to be used although

a proprietary liquid type suitable for solar conditions may be used. Any drain valves etc. must be capable of handling the

temperatures indicated above. Any fittings and pipework must be capable of withstanding 1.5 times the safety valve pressure.

insulation:

This should be High Temperature Armaflex or similar grade insulation or above. Class O Armaflex is not UV-resistant

or designed for the temperatures realised in the solar primary circuit. Polythene insulation will melt on a solar primary circuit. All

external items such as cable clips to hold the collector sensor must be UV-resistant.
Flexible stainless steel hose is available in pre-insulated form using suitable high temperature UV-resistant insulation and a suitable

two-core cable for the solar collector sensor. This hose is specifically designed for solar applications.

Before starting any work check the solar pack contents. Please note, dependent upon specific solar pack, ordered contents may vary.
