1.2.3 Refrigerant
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.
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.
DANGER: RISK OF EXPLOSION
Pump down Refrigerant leakage. If you want to pump
down the system, and there is a leakage 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
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.
In case re-charge is required, refer to 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
(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.

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, MUST be installed in the fixed wiring.
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 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.
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.
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.
