Installer reference guide
9
1 | General safety precautions
▪ 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:
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.
IfThen
A siphon tube is present
Charge with the cylinder upright.
(i.e., the cylinder is marked with "Liquid
filling siphon attached")
A siphon tube is NOT presentCharge 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.

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.
Installer reference guide
12
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.

5.2 Setting up the space heating/cooling system
NOTICE
Certain types of fan coil units –in this document referred to as "heat pump
convectors"–, are able to receive input of the indoor unit operation mode (cooling or
heating X2M/3 and X2M/4) and/or to send output of the heat pump convector
thermostatic condition (main zone: X2M/30 and X2M/35; additional zone: X2M/30
and X2M/35a).
The application guidelines illustrate the possibility of receiving or sending digital
input/output. This functionality can only be used in case the heat pump convector
has such features and the signals meet following requirements:
▪ Output of indoor unit (input to heat pump convector): cooling/heating
signal=230V (cooling=230V, heating=0V).
▪ Input to indoor unit (output of heat pump convector): thermostat ON/OFF
signal=voltage-free contact (closed contact=thermo ON, open contact=thermo
OFF).
The heat pump system supplies leaving water to heat emitters in one or more
rooms.
Because the system offers a wide flexibility to control the temperature in each
room, you need to answer the following questions first:
▪ How many rooms are heated or cooled by the heatpump system?
▪ Which heat emitter types are used in each room and what is their design leaving
water temperature?
Once the space heating/cooling requirements are clear, we recommend to follow
the setup guidelines below.
NOTICE
If an external room thermostat is used, the external room thermostat will control the
room frost protection. However, the room frost protection is only possible if [C.2]
Space heating/cooling=On.
INFORMATION
In case an external room thermostat is used and room frost protection needs to be
guaranteed in all conditions, then you have to set Emergency [9.5.1] to
Automatic.
NOTICE
An overpressure bypass valve can be integrated in the system. Keep in mind that this
valve might not be shown on the illustrations.
