CLOSED LOOP PIPING

 

y

All pipes starting from and resulting to collectors must by appropriately insulated in order to resist to temperatures 

from -30°C to +120°C. It is also necessary to protect insulating material from UV rays.

 

y

The thickness of insulation depends on the local climate conditions.

 

y

To minimize heat losses, the distance between collectors and the boiler heat exchanger must be the smallest 

possible. 

 

y

Avoid the concentration of air. If this is not possible, the installation of an automatic ventilator at the air accumulation 

point. concentration is necessary. 

 

y

Pipes diameter must be from Ø18mm to Ø22mm for distances up to 20 meters and Ø15mm for distances up to 

12 meters.

 

y

All the union nuts must resist compression 6 bar and temperatures from -30°C to +200°C. 

 

y

The annual check of the equipment and its connections is mandatory. 

POST INSTALLATION INSTRUCTIONS

Before using the system make a final check. Open all the valves and check for any kind of leakage. Repeat the 

inspection after 30 minutes. Check if the system is filled with water and antifreeze fluid according to the company’s 

instructions. In case of any failure condition a specialized technician should be called in.

A basic periodic maintenance will assure the long life and high efficiency of the solar installation.

 

y

It is recommended that the appliance is inspected in situ according to the instructions stated in the guarantee 

twice a year and checked for possible damage (breaking) of the collectors’ glass, leaks in the connecting piping to 

the mains and to the consumption system, inspection of the pipe insulation and cleaning of the glass.

 

y

If the collectors’ glass is broken, it should be replaced immediately.

 

y

It is recommended that the glass is washed at an hour of low sunlight to avoid damages due to expansion-

contraction, due to temperature changes.

 

y

 If the fittings are worn (screws, pugs, piping, etc), these should be replaced at the owner’s cost. 

 

y

The level of antifreeze in the closed circuit must be checked annually (as it could need toping up), to ensure the 

efficient operation.

 

y

In cases where there is to be no use of hot water for long periods of time (e.g. during the summer holidays), it is 

recommended that the collector surface is covered with an opaque cover in order to avoid the building up of high 

temperatures.

ATTENTION!

 Place taps with thermostatic regulation up to 38°C for hot water use to prevent burns which may be 

caused by the high temperature water in the solar installation.
