3.2.2 Installation site
▪ Provide sufficient space around the unit for servicing and air
circulation.
▪ Make sure the installation site withstands the unit’s weight and
vibration.
▪ Make sure the area is well ventilated.
▪ Make sure the unit is level.
▪ Make sure walls sensitive to heat (e.g. wood) are protected by
suitable insulation.
▪ ONLY operate the gas boiler if a sufficient supply of combustion
air is ensured. In case of a concentric air/flue gas system
dimensioned according to the specifications of this manual, this is
fulfilled automatically and there are no other conditions for the
equipment installation room. This method of operation applies
exclusively.
▪ This gas boiler is NOT designed for room air dependent operation.
Do NOT install the unit in the following places:
▪ In potentially explosive atmospheres.
▪ In places where there is machinery that emits electromagnetic
waves. Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
▪ In places where there is a risk of fire due to the leakage of
flammable gases (example: thinner or gasoline), carbon fibre,
ignitable dust.
▪ In places where corrosive gas (example: sulphurous acid gas) is
produced. Corrosion of copper pipes or soldered parts may cause
the refrigerant to leak.
▪ In bathrooms.
▪ In places where frost is possible. The ambient temperature around
the indoor unit should be >5°C.
3.2.3 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.
3.2.4 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.
NOTICE
If there exists the possibility of reversed phase after a
momentary black out and the power goes on and off while
the product is operating, attach a reversed phase
protection circuit locally. Running the product in reversed
phase can break the compressor and other parts.
