VHM 2.1 - 2.7
Important
In case of roof installation, before starting the work, prepare
antifall or generic safety devices in conformity with the
regulations. Respect the specific regulations in the country!
If, for technical work reasons, there cannot be
antifall and generic safety devices,
use safety harnesses!
Only use approved safety harnesses
provided with the mark issued by
official control bodies (support and
safety belts, safety ropes/straps, fall
arresting belts, rope shorteners).
If there are no antifall and
safety devices, failure to use safety harnesses
can be the cause of falls from considerable heights
resulting in serious or fatal injury!
When ladders are used,
dangerous falls can occur if the ladder
sinks, slides or falls.
Work near uncovered electric lines
only if:
- the power is disconnected and this condition is guaranteed
for the entire duration of the work
- the voltage conducting parts are protected
by covering or barrier
- the safety distances are respected:
1 m........................ with 1000 Volts
3 m...........with 1000 to 11000 Volts
4 m......... with 11000 to 22000 Volts
5 m......... with 22000 to 38000 Volts
> 5 m with unknown voltage
Only use the recommended
heat transfer fluid!
If the collector and the assembly material have remained
in the sun for a long time there is risk of burns if touched.
Any leaking of the O-ring sealing system, due to incorrect
installation, use non-compliant parts or tampering, can cause
irreparable leakage of system liquid inside the panel. This
can permanently compromise panel functionality.
If possible, hook the safety harness
above the user. Only fix the safety harness
to secure hooking points or
elements!
Do not use damaged ladders, e.g.
ladders with broken handrails and rungs, or bent or buckled
metal ladders. Do not repair
broken handrails, bars and rungs of wooden ladders!
Position ladders in a secure way.
Respect the correct lean angle (68°-75°).
Make sure ladders cannot slide, fall over or sink, for example by en-
larging the feet, using feet suitable for the support surface, and using
hooking devices.
Only lean ladders on secure support places.
In traffic zones, protect ladders by means of
barriers
Contact with uncovered live electric lines
can have fatal consequences.
During perforation work and when handling
vacuum tube collectors wear protective glasses
(risk of explosion)!
During installation wear safety
shoes!
During installation of the collectors and when handling
vacuum tube collectors wear
protective cut-resistant gloves (risk of explosion)!
During installation wear a safety helmet!
During installation cover the collector (e.g. with a tarpaulin) and the
assembly material to protect them from the high temperature due to
the sun.
If the solar circuit TIGHTNESS TEST is done with pure water without
added antifreeze (INADVISABLE), make sure to empty the circuit
COMPLETELY at the end of the test and immediately fill it with a solu-
tion containing ANTIFREEZE or a suitable premixed solar fluid (e.g.
FERSOL LT or ULTRA LT).
The rule for calculating the frost protection level for a solar system is to
consider the MINIMUM DESIGN TEMPERATURE of the place for heating
systems (e.g. Law 10/91) SUBTRACTING ANOTHER 7° for "windchill"
(rapid heat loss due to wind) and the "clearsky" effect (night radiance
with clear sky) on the collector installed on the roof.
The manufacturer declines any liability for damage caused by frost
whenever the
above COMPULSORY instructions are ignored.
NEVER use solar circuit automatic filling devices directly connected to
the mains water, as these do not allow the replenishing of any small
leaks (even prolonged) with the correct added mixture of antifreeze,
diluting the level of protection and putting at risk the integrity of the
collector at the connections (plastic unions) and, in serious cases, the
internal piping.
Any devices for replenishing the specific fluid solar can be used only
in the presence of good quality mains water (absence of sludge, hard
or brackish water) after a chemical-physical analysis, and in any case
providing for a specific antifreeze dosing pump to add a suitable mixture
of quality equal to the solar mixture of the original filling.
The manufacturer declines any liability for damage caused by frost
whenever the
above COMPULSORY instructions are ignored.
