Precautions - Riello RPS 25/4 Installer, Technical Assistan Ce Service And User Manual

GENERAL INFORMATION
9
The system must be installed by specialist personnel. Use
only the assembly material supplied with the solar collec-
tor. The supporting framework and all masonry or brickwork
fixing points must be checked by a person expert in static
loading, and must be suitable for the nature of the instal-
lation site.
9
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 complies with relevant stand-
ards, 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 in-
crease the loads on the supporting structure.
9
Solar collector pipes must be connected through a (yel-
low-green) connector of at least 16 mm
to the potential compensation main bar. If a lighting rod is
already installed, collectors can be integrated in the exist-
ing 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 hav-
ing the same diameter.
9
All pipes in the water circuit must be insulated in conform-
ity to relevant standards. Lagging and insulation must be
protected against damage by the weather and birds and
animals.
9
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 product. It
must be kept safe and must ALWAYS accompany the product,
even if it is sold to another owner or transferred to another
user or to another installation. If you lose this manual, or-
der a replacement immediately. Keep the product purchase
documents to be presented to the
Assistance Service to request a service call under warranty.
9
Size the solar expansion tank so as to ensure complete ab-
sorption of the expansion of the fluid contained within the
system, with reference to the prevailing regulations on the
matter. In particular, consider fluid characteristics, consid-
erable 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 vol-
ume changes of the heat transfer fluid, avoiding excessive
pressure increase. Limited pressure changes avoid reach-
ing safety valve opening pressure and the consequent fluid
drainage.

2 PRECAUTIONS

9
Always wear safety goggles when drilling. Always wear safe-
ty shoes, cut-proof protective gloves and a safety helmet
when performing installation work.
9
Before beginning installation work on roofs, install the nec-
essary fall prevention and fall arrest devices and ensure that
all applicable safety standards are applied. Use only tools
and materials that conform to the safety standards that are
applicable in the place of work.
9
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 cover-
ing and allowing operating in complete safety.
9
The use of ladders leaned against walls can lead to serious
falls if the ladder slips, slides of falls. When using ladders,
always ensure that they are stable, and that suitable ladder
stops are present. If possible secure the ladder with hooks.
Make sure that there are no live electrical wires near the
ladder.
0
Never attempt to install the system without using suitable
personal protection equipment and without following all
applicable occupational safety standards.
0
Do not touch the product when barefoot or wet if it has any
electrical accessories installed in it.
0
Never clean or service the storage cylinder without first
turning the mains power switch OFF to disconnect all elec-
trical accessories (if fitted) from the mains electricity supply.
0
If solar plant pressure decreases, it is forbidden to top up
with only water as there is a danger of freezing and over-
heating.
0
Do not dispose of packaging material into the environment,
or leave it within the reach of children, since it can become
a potential hazard. Dispose of packaging material in com-
pliance with applicable legislation.
