1 | General safety precautions
▪ Make sure the area is well ventilated. Do NOT block any ventilation openings.
▪ Make sure the unit is level.
▪ If the wall on which the unit is mounted is flammable, a non-flammable material
must be placed between the wall and the unit. Do the same for all locations
through which the flue piping passes.
▪ 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.
▪ Store flammable fluids and materials at least 1meter away from the gas boiler.
▪ 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 gas boiler
should be >5°C.
1.2.3 Refrigerant — in case of R410A or R32
If applicable. See the installation manual or installer reference guide of your
application for more information.
NOTICE
Make sure refrigerant piping installation complies with applicable legislation. In
Europe, EN378 is the applicable standard.
NOTICE
Make sure the field piping and connections are NOT subjected to stress.

1 | General safety precautions
DANGER: RISK OF EXPLOSION
Pump down – Refrigerant leakage. If you want to pump down the system, and there
is a leak in the refrigerant circuit:
▪ Do NOT use the unit's automatic pump down function, with which you can collect
all refrigerant from the system into the outdoor unit. Possible consequence: Selfcombustion and explosion of the compressor because of air going into the
operating compressor.
▪ Use a separate recovery system so that the unit's compressor does NOT have to
operate.
WARNING
ALWAYS recover the refrigerant. Do NOT release them directly into the environment.
Use a vacuum pump to evacuate the installation.
NOTICE
After all the piping has been connected, make sure there is no gas leak. Use nitrogen
to perform a gas leak detection.
NOTICE
▪ To avoid compressor breakdown, do NOT charge more than the specified amount
of refrigerant.
▪ When the refrigerant system is to be opened, refrigerant MUST be treated
according to the applicable legislation.
WARNING
Make sure there is no oxygen in the system. Refrigerant may only be charged after
performing the leak test and the vacuum drying.
Possible consequence: Self-combustion and explosion of the compressor because of
oxygen going into the operating compressor.
▪ In case recharge is required, see the nameplate of the unit. It states the type of
refrigerant and necessary amount.
▪ The unit is factory charged with refrigerant and depending on pipe sizes and pipe
lengths some systems require additional charging of refrigerant.
▪ Only use tools exclusively for the refrigerant type used in the system, this to
ensure pressure resistance and prevent foreign materials from entering into the
system.
▪ Charge the liquid refrigerant as follows:
If Then
A siphon tube is present
Charge with the cylinder upright.
(i.e., the cylinder is marked with "Liquid
filling siphon attached")

When the refrigerant charging procedure is done or when pausing, close the valve of
the refrigerant tank immediately. If the valve is NOT closed immediately, remaining
pressure might charge additional refrigerant. Possible consequence: Incorrect
refrigerant amount.
If applicable. See the installation manual or installer reference guide of your
application for more information.
NOTICE
Make sure water quality complies with EU directive 98/83EC.
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 (>3mmol/l–sum of the calcium
and magnesium concentrations, calculated as calcium carbonate).
1.2.5 Electrical
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.
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 10minutes, and measure the voltage
at the terminals of main circuit capacitors or electrical components before
servicing. The voltage MUST be less than 50VDC 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
categoryIII condition, MUST be installed in the fixed wiring.

1 | General safety precautions
WARNING
▪ ONLY use copper wires.
▪ Make sure the field wiring complies with the applicable legislation.
▪ 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
electrical 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.
CAUTION
▪ When connecting the power supply: connect the earth cable first, before making
the current-carrying connections.
▪ When disconnecting the power supply: disconnect the current-carrying cables
first, before separating the earth connection.
▪ The length of the conductors between the power supply stress relief and the
terminal block itself must be as such that the current-carrying wires are tautened
before the earth wire is in case the power supply is pulled loose from the stress
relief.
NOTICE
Precautions when laying power wiring:
▪ Do NOT connect wiring of different thicknesses to the power terminal block (slack
in the power wiring may cause abnormal heat).
▪ When connecting wiring which is the same thickness, do as shown in the figure
above.
▪ For wiring, use the designated power wire and connect firmly, then secure to
prevent outside pressure being exerted on the terminal board.
▪ Use an appropriate screwdriver for tightening the terminal screws. A screwdriver
with a small head will damage the head and make proper tightening impossible.
▪ Over-tightening the terminal screws may break them.

Install power cables at least 1 m away from televisions or radios to prevent
interference. Depending on the radio waves, a distance of 1 m may not be
sufficient.

1 | General safety precautions
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
Only applicable if the power supply is three‑phase, and the compressor has an ON/
OFF starting method.
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.
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 gas pressure quoted on the type identification plate.
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 22mm.
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.
DANGER
If you smell gas:
▪ call immediately your local gas supplier and your installer,
▪ call the suppliers's number on the side of the LPG tank (if applicable),
▪ turn off the emergency control valve at the meter/regulator,
▪ do NOT turn electrical switches ON or OFF,
▪ do NOT strike matches or smoke,
▪ put out naked flames,
▪ open doors and windows immediately,
▪ keep people away from the affected area.
