WARNING
During tests, NEVER pressurize the product with a
pressure higher than the maximum allowable pressure (as
indicated on the nameplate of the unit).
WARNING
Take sufficient precautions in case of refrigerant leakage. If
refrigerant gas leaks, ventilate the area immediately.
Possible risks:
▪ Excessive refrigerant concentrations in a closed room
can lead to oxygen deficiency.
▪ Toxic gas may be produced if refrigerant gas comes
into contact with fire.
WARNING
Always recover the refrigerants. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.
3.2.4 Water
NOTICE
Make sure water quality complies with EU directive
98/83 EC.
Avoid damages caused by deposits and corrosion. To prevent
corrosion products and deposits, observe the applicable regulations
of technology.
Measures for desalination, softening or hardness stabilization are
necessary if the filling and top-up water have a high total hardness
(>3 mmol/l–sum of the calcium and magnesium concentrations,
calculated as calcium carbonate).
Using filling water and top-up water which does NOT meet the stated
quality requirements can cause a considerably reduced service life
of the equipment. The responsibility for this is entirely that of the
user.
3.2.5 Electrical
DANGER: RISK OF ELECTROCUTION
▪ Turn OFF all power supply before removing the
switch box cover, connecting electrical wiring or
touching electrical parts.
▪ Disconnect the power supply for more than 1 minute,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing.
The voltage MUST be less than 50 V DC before you
can touch electrical components. For the location of the
terminals, see the wiring diagram.
▪ Do NOT touch electrical components with wet hands.
▪ Do NOT leave the unit unattended when the service
cover is removed.
WARNING
If NOT factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage category III
condition, shall be installed in the fixed wiring.
WARNING
▪ ONLY use copper wires.
▪ All field wiring must be performed in accordance with
the wiring diagram supplied with the product.
▪ NEVER squeeze bundled cables and make sure they
do not come in contact with the piping and sharp
edges. Make sure no external pressure is applied to the
terminal connections.
▪ Make sure to install earth wiring. Do NOT earth the unit
to a utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.
▪ Make sure to use a dedicated power circuit. NEVER
use a power supply shared by another appliance.
▪ Make sure to install the required fuses or circuit
breakers.
▪ Make sure to install an earth leakage protector. Failure
to do so may cause electric shock or fire.
▪ When installing the earth leakage protector, make sure
it is compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
Install power cables at least 1 meter away from televisions or radios
to prevent interference. Depending on the radio waves, a distance of
1 meter may not be sufficient.
WARNING
▪ After finishing the electrical work, confirm that each
electrical component and terminal inside the electrical
components box is connected securely.
▪ Make sure all covers are closed before starting up the
unit.
3.2.6 Gas
The gas boiler is factory set to:
▪ the type of gas quoted on the type identification plate or on the
setting type identification plate,
▪ the quitted gas pressure.
Operate the unit ONLY with the gas type and gas pressure indicated
on these type identification plates.
Installation and adaptation of the gas system MUST be conducted
by:
▪ personnel qualified for this work,
▪ in compliance with valid gas installation related guidelines,
▪ in accordance with applicable regulations of the gas supply
company,
▪ In accordance with local and national regulations.
Boilers that use natural gas MUST be connected to a governed
meter,
Boilers that use liquid petroleum gas (LPG) MUST be connected to a
regulator.
The size of the gas supply pipe should under no circumstance be
less than 22 mm.
The meter or regulator and pipe work to the meter MUST be
checked preferably by the gas supplier. This is to ensure that the
equipment works good and meets the gas flow and pressure
requirements.
