GENERAL INFORMATION

GENERAL INFORMATION

The system must be installed by specialist personnel. 

Use only the assembly material supplied with the solar 

collector. The supporting framework and all masonry or 

brickwork fixing points must be checked by a person ex-

pert in static loading, and must be suitable for the nature 

of the installation site.

The solar collector must only be installed on roofs or 

frames that are strong enough to support its weight. The 

strength of the roof or frame must be verified on site by a 

person expert in static loading before the solar collector 

is installed. During this process, it is important to verify 

the suitability of the supporting frame to hold the screw 

fasteners that fix the solar collector in place. An expert 

in static loading must verify that the entire frame com-

plies with relevant standards, especially in areas liable 

to snow and areas exposed to high winds. Conditions 

(gusts of wind, formation of wind vortices, etc.) at the 

point where the solar collector is to be installed must be 

carefully considered since these can increase the loads 

on the supporting structure.

Solar collector pipes must be connected through a (yel-

low-green) connector of at least 16 mm

2

 Cu (H07 V-U o 

R) to the potential compensation main bar. If a lighting 

rod is already installed, collectors can be integrated in 

the existing system. If this is not the case, it is possible 

to carry out earthing with a buried earth cable. The earth 

duct must be laid outside the house. Furthermore, the 

earth cable must be connected to the compensation bar 

through a duct having the same diameter.

All pipes in the water circuit must be insulated in con-

formity to relevant standards. Lagging and insulation 

must be protected against damage by the weather and 

birds and animals.

The collector is suitable for a minimum inclination of 15°, 

up to a maximum of 75°.

This instruction manual is an integral part of the prod-

uct. It must be kept safe and must ALWAYS accompany 

the product, even if it is sold to another owner or trans-

ferred to another user or to another installation. If you 

lose this manual, order a replacement immediately. Keep 

the product purchase documents to be presented to the 

T

 authorised Technical Assistance Centre to 

request a service call under warranty.

Size the solar expansion tank so as to ensure complete 

absorption of the expansion of the fluid contained within 

the system, with reference to the prevailing regulations 

on the matter. In particular, consider fluid characteris-

tics, considerable fluctuation of service temperature and 

vapour that might be generated during solar collector 

stagnation stage. Proper size of expansion tank ensures 

setting off of all volume changes of the heat transfer fluid, 

avoiding excessive pressure increase. Limited pressure 

changes avoid reaching safety valve opening pressure 

and the consequent fluid drainage.

PRECAUTIONS

Always wear safety goggles when drilling. Always wear 

safety shoes, cut-proof protective gloves and a safety 

helmet when performing installation work.

Before beginning installation work on roofs, install the 

necessary fall prevention and fall arrest devices and en-

sure that all applicable safety standards are applied. Use 

only tools and materials that conform to the safety stand-

ards that are applicable in the place of work.

Use only overalls with harness (with lacing or restraining 

belt, connection ropes or bands, fall dampeners, heat 

sinks) certified for the risk detected according to the type 

of covering and allowing operating in complete safety.

The use of ladders leaned against walls can lead to se-

rious falls if the ladder slips, slides of falls. When using 

ladders, always ensure that they are stable, and that suit-

able ladder stops are present. If possible secure the lad-

der with hooks. Make sure that there are no live electrical 

wires near the ladder.

Never attempt to install the system without using suitable 

personal protection equipment and without following all 

applicable occupational safety standards.

Do not touch the product when barefoot or wet if it has 

any electrical accessories installed in it.

Never clean or service the storage cylinder without first 

turning the mains power switch OFF to disconnect all 

electrical accessories (if fitted) from the mains electricity 

supply.

If solar plant pressure decreases, it is forbidden to top 

up with only water as there is a danger of freezing and 

overheating.

Do not dispose of packaging material into the environ-

ment, or leave it within the reach of children, since it can 

become a potential hazard. Dispose of packaging mate-

rial in compliance with applicable legislation.
