2.1.3 Refrigerant — in case of R410A or R32
If applicable. See the installation manual or installer reference guide of your
application for more information.
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: Self-
combustion 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
During tests, NEVER pressurise 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 might be produced if refrigerant gas comes into contact with fire.
WARNING
ALWAYS recover the refrigerant. Do NOT release them directly into the environment.
Use a vacuum pump to evacuate the installation.
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.
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.
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.

4P728168-4 – 2023.03
NOTICE
After all the piping has been connected, make sure there is no gas leak. Use nitrogen
to perform a gas leak detection.
▪In case recharge is required, see the nameplate or the refrigerant charge label of
the unit. It states the type of refrigerant and necessary amount.
▪Either if the unit is factory charged with refrigerant or the unit is non-charged,
you might need to charge additional refrigerant, depending on the pipe sizes and
pipe lengths of the system.
▪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
(i.e., the cylinder is marked with "Liquid
filling siphon attached")
Charge with the cylinder upright.
A siphon tube is NOT present Charge with the cylinder upside down.
▪Open refrigerant cylinders slowly.
▪Charge the refrigerant in liquid form. Adding it in gas form may prevent normal
operation.
CAUTION
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.
2.1.4 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 10minutes, and measure the voltage

▪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.
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.
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 meter away from televisions or radios to prevent
interference. Depending on the radio waves, a distance of 1 meter may NOT be
sufficient.
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.

WARNING
▪If the power supply has a missing or wrong N-phase, equipment might break
down.
▪Establish proper earthing. Do NOT earth the unit to a utility pipe, surge absorber,
or telephone earth. Incomplete earthing may cause electrical shock.
▪Install the required fuses or circuit breakers.
▪Secure the electrical wiring with cable ties so that the cables do NOT come in
contact with sharp edges or piping, particularly on the high-pressure side.
▪Do NOT use taped wires, extension cords, or connections from a star system.
They can cause overheating, electrical shock or fire.
▪Do NOT install a phase advancing capacitor, because this unit is equipped with an
inverter. A phase advancing capacitor will reduce performance and may cause
accidents.
WARNING
Use an all-pole disconnection type breaker with at least 3mm between the contact
point gaps that provides full disconnection under overvoltage category III.
WARNING
If the supply cord is damaged, it MUST be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
WARNING
Do NOT connect the power supply to the indoor unit. This could result in electrical
shock or fire.
WARNING
▪Do NOT use locally purchased electrical parts inside the product.
▪Do NOT branch the power supply for the drain pump, etc. from the terminal
block. This could result in electrical shock or fire.
WARNING
Keep the interconnection wiring away from copper pipes without thermal insulation
as such pipes will be very hot.
