Collector panels must be connected in series.The
connections are 1" BSP female union connections.
All connecting pipe work and fittings must be of a
suitable metal; either copper, brass or stainless steel.
Soft soldered joints must not be used.Any seals or sealing
compounds must be resistant to temperatures of up to
150°C and be resistant up to a 50% glycol/water mix.
Connections
When tightening the connections, always apply
counter-pressure with a wrench or another spanner
to prevent damage to the absorber.
East
Collector inclination
The collector is suitable for angles between 15°
(minimum) and 75° (maximum).
The roof aspect should ideally face South, however
orientations between 30° East and 40°West of South are
acceptable. Fig.3 shows the efficiency loss for varying
angles of inclinations and roof orientation.
Solar fluid
The Potterton Solar collector panels MUST be
protected with a water/glycol heat transfer fluid. Use only
the fluid supplied with the system which is supplied pre-
mixed to a concentration of 40% glycol / 60% water.Top
10-20%
ups can be made with water but the glycol concentration
must not be allowed to fall below 30% or inadequate frost
protection will be given. Systems found to have lower
glycol concentrations will not be covered by the warranty.
