8. INSTRUCTIONS FOR THE INSTALLER
GENERAL WARNINGS
Any modification to the products (Panel, Frame, Kettle,
Fittings, etc.) is not allowed. The manufacturer assumes no
liability of any kind for modified products.
WARNING!
This appliance must only be used for the use for which it was
expressly intended. Any other use is to be considered improper
and therefore dangerous.
This appliance uses the solar thermal fluid to heat water to a
temperature below boiling point at atmospheric pressure.
Before connecting the appliance, have professionally qualified
personnel carry out a thorough washing of all the system pipes
to remove any residues or impurities that could compromise the
proper functioning of the appliance.
WARNING!
The appliance must be installed by a qualified technician in
possession of the technical-professional requirements
according to the Ministerial Decree 37/08 which, under its own
responsibility, guarantees compliance with the rules according
to the rules of good practice.
GENERAL DANGER INSTRUCTIONS
IN GENERAL
The solar system must be assembled and operated in compliance
with the recognized technical rules.
Observe the applicable accident prevention and protection
regulations, especially for work on the roof.
Observe the accident prevention regulations of the Institute for
Insurance against accidents at work.
DANGER OF OVER VOLTAGE
Ground the solar circuit for equipotential bonding as surge
protection.
Apply hose clamps with grounding screws to the solar circuit
pipes to be connected with a 16 mm2 copper cable to a potential
equalization bar.
CORRECT USE OF THE SUPPORT LADDER
The
ladders must be placed on safe points at an angle between 65°
and 75°; respect a stair protrusion of at least 1 m from the climb
over point to pass over the roof.
The stairs must also be secured against slipping, tipping and
sagging.
Finally, use ladders only to overcome differences in height of
max. 5m.
PROTECTION FROM FALLING OBJECTS
The passageways or workstations that are located under the
affected area must be protected from objects that can fall, slide
or roll off the roof.
Marking, delimiting and barring areas that represent a danger to
people.
SCAFFOLDING FOR FALL PROTECTION
For work on sloping roofs (from 20° to 60°) fall protection is required
starting from a height of 3 m.
Roof fall protection scaffolding is a solution. The vertical distance
between the workplace and the guard it must be a maximum of 5 m.
With an inclination of the roof greater than 45 ° it is necessary to
create special workstations.
FALL PROTECTION WALL
A further possibility of protection for works on sloping roofs (up to
60°) starting from a fall height of 3 m are the roof protection walls.
The vertical distance between the work station and the guard
must be a maximum of 5 m.
The protective walls must protrude laterally by at least 2 m.
FALL SAFETY EQUIPMENT
If the scaffolding or the roof protection wall are not suitable, it is
possible to use fall safety equipment.
Apply the roof safety hook to solid construction parts, possibly
above the user.
DANGER OF FALL
Do not use the hooks on the roof! The safety equipment must
only be used in combination with the special safety hooks against
falling from the roof.
DANGERS OF BURNS
To prevent burns due to parts of the collector at high temperatures,
take the following measures: install the collector only on cloudy
days; on sunny days it is preferable to work early in the morning
or in the evening, or after having carefully covered the collector.
