2 | General safety precautions

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 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.

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:

▪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.
