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.
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.

1 | General safety precautions
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") |
|
|
|
|
|
||
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.
If applicable. See the installation manual or installer reference guide of your
application for more information.

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.

5 | Application guidelines
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=230 V (cooling=230 V, heating=0 V).
▪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 heat pump 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.

Benefits
▪Highest comfort and efficiency. The smart room thermostat functionality can decrease or increase the desired leaving water temperature based on the actual room temperature (modulation). This results in:
-Stable room temperature matching the desired temperature (higher comfort)
-Less ON/OFF cycles (more quiet, higher comfort and higher efficiency)
-Lowest possible leaving water temperature (higher efficiency)
▪Easy. You can easily set the desired room temperature via the user interface:
-For your daily needs, you can use preset values and schedules.
-To deviate from your daily needs, you can temporarily overrule the preset values and schedules, or use the holiday mode.
