Branch pipe lines: 1 inch or 3/4 inch

For a solar installation with pipe work of total length 30 to 50 meters, the following dimensions are recommended 
for the flow and return pipe work: 

Less than 36 tubes 12 mm or ½ inch-possible, but recommend ¾ inch. 
Up to 90 tubes 22 mm or ¾ inch 
Up to 120 tubes 128 mm or 1 inch 
More than 120 tubes – use parallel branches of 1 inch each. 

Pipe work should be insulated with ¾ inch minimum high temperature pipe insulation, more insulation in more 
extreme cold environments.

Heat Transfer Media 

Any kind of liquid may be heated by the heat exchanger. In areas where chloride ion concentration is greater than 40 
ppm a heat exchanger must be used in the hot water storage tank. The solar system should be filled with distilled or 
de-chlorinated water, or another clean fluid such as glycol.

Precautions 

Note: In order to avoid jamming the digital flow meter and in result to display no flow on solar station, the filter( A ) 
must be installed on the return and flow pipeline of the solar station. 

All devices connected to the controller must conform to the technical specification of the controller. Assembly, 
installation and maintenance work may only be performed by properly qualified and authorized personnel with a 
generally recognized qualification. 

The solar station must be installed indoors. Prior to installation, remove the sealing caps from the solar station. 

The maximum distance between the solar station and the water tank is 300 mm (about 12 inches).   

Pre-setting, installing and adjusting the expansion tank as per the installation and operation instruction for “expansion 
tank ", the corrugated connection pipe for the expansion tank does not need thermal insulation. 

Safety valve: There is a risk of scalding from hot steam with discharge from the safety valve due to heating and 
excess pressure in the hydraulic pipes. Drain off the discharge from the safety valve using a copper pipe correctly and 
in an eco-friendly way, according to valid technical regulations and building codes and local regulations, do not allow 
solar fluid to leak into the environment.   

Be careful of scalding from hot fluid. Maximum temperature of collectors during filling/leak check or 
installation/maintenance work should be below 70

°

C

. Allow collectors to cool down if necessary.
