1.2 Qualifi cations
Any work carried out must be by suitably qualifi ed personnel.
∙ Incorrect installation can cause damage to the unit, to the
site or injury to others.
1.3 General safety advices
∙ Before to read this chapter, also read the general safety
advices of the operating instructions.
1.3.1 Danger to life by electric shock
Touching live connections can cause serious personal injury.
∙ Before carrying out any work on the product, switch off the
power supply.
∙ Secure the power supply against being switched on again.
1.3.2 Danger to life due to missing or not properly
working safety devices
Missing safety devices can cause life-threatening scalding
and other injuries, for example by burst pipes.
The information contained in this document do not show all
schemes required for a professional installation of safety
devices.
∙ Install the necessary safety devices in the system.
∙ Inform the user about the function and location of safety
devices.
∙ Observe the relevant national and international laws,
standards and guidelines.
1.3.3 Danger due to improper use
Nonprofessional work on the product can cause damage to
the installation and as a consequence even personal injury.
∙ Only work on the product if you are a competent person.
1.3.4 Risk of material damage by additives in the
heating water
Frost and corrosion protection agents can cause changes
to seals, noise during heating mode and may lead to other
consequential damage.
∙ Do not use any unsuitable frost or corrosion protection
agents.
1.3.5 Risk of material damage caused by
unsuitable tools
The use of unsuitable tools or improper use thereof may cause
damage, such as gas or water leaks.
∙ When tightening or loosening threaded connections,
always use suitable opened spanners, but do not use pipe
wrenches, extensions, etc.
1.3.6 Risk of structural damages by escaping water
Incorrect installation can cause leakages.
∙ Make sure there are no stresses in the hydraulic lines.
∙ Correctly position the seals.
1.4 R410A Refrigerant
a Danger!
Risk of injury due to incorrect work on the refrig-
erant circuit!
The appliance contains refrigerant fluid and must
be handled with caution. Any work on the refriger-
ant circuit must be performed by trained and
approved personnel.
•
Only work on the refrigerant circuit if you are a
trained and approved specialist equipped with
appropriate protective equipment.
•
Perform draining and filling operations in a
properly ventilated area.
•
Avoid any contact with the skin or eyes.
R410A fl uorinated greenhouse gases are contained within
a fully sealed system (Kyoto Protocol PES 1975). Under
normal use and conditions, the refrigerant is not dangerous.
Degassing refrigerant fl uid into the atmosphere is prohibited,
except when necessary to ensure personal safety.
The refrigerant fl uid contains gases that, when released into
the atmosphere, may aff ect the environment, contributing
to the greenhouse eff ect and an increase in temperature.
The risk of leakage cannot be excluded for devices intended
to operate for many years and subject to the eff ects of the
environment.
∙ Use only R410A refrigerant.
∙ The tools used for charging, for measuring pressure, for
creating a vacuum and for the recovery of the fl uid must be
compatible with and employed solely for R410A.
