1.2.3Refrigerant

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 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

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	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.

1.2.4Brine

If applicable. See the installation manual or installer reference guide of your application for more information.

WARNING

The selection of the brine MUST be in accordance with the applicable legislation.

WARNING

Take sufficient precautions in case of brine leakage. If brine leaks, ventilate the area immediately and contact your local dealer.

WARNING

The ambient temperature inside the unit can get much higher than that of the room, e.g. 70°C. In case of a brine leak, hot parts inside the unit can create a hazardous situation.

WARNING

The use and installation of the application MUST comply with the safety and environmental precautions specified in the applicable legislation.

1.2.5Water

If applicable. See the installation manual or installer reference guide of your application for more information.

NOTICE

Make sure water quality complies with EU directive 98/83 EC.

2 About the documentation

1.2.6Electrical

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.

CAUTION

When connecting the power supply, the earth connection must be made before the current-carrying connections are established. When disconnecting the power supply, the current-carrying connections must be separated before the earth connection is. 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.

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.

5 Preparation

5.1Overview: Preparation

This chapter describes what you have to do and know before going on-site.

It contains information about:

▪Preparing the installation site

▪Preparing the refrigerant piping

▪Preparing the electrical wiring

5.2.1Installation site requirements of the indoor unit

INFORMATION

Also read the precautions and requirements in the "General safety precautions" chapter.

INFORMATION

The sound pressure level is less than 70 dBA.

▪Air flow. Make sure nothing blocks the air flow.

▪Drainage. Make sure condensation water can be evacuated properly.

▪Wall insulation. When conditions in the wall exceed 30°C and a relative humidity of 80%, or when fresh air is inducted into the wall, then additional insulation is required (minimum 10 mm thickness, polyethylene foam).

▪Wall strength. Check whether the wall or the floor is strong enough to support the weight of the unit. If there is a risk, reinforce the wall or the floor before installing the unit.

Install power cables at least 1 metre away from televisions or radios to prevent interference. Depending on the radio waves, a distance of 3 metres may NOT be sufficient.

▪Choose a location where the hot/cold air discharged from the unit or the operation noise, will NOT disturb anyone.

▪Fluorescent lights. When installing a wireless user interface in a room with fluorescent lights, mind the following to avoid interference:

▪Install the wireless user interface as close as possible to the indoor unit.

▪Install the indoor unit as far as possible from the fluorescent lights.

It is NOT recommended to install the unit in the following places because it may shorten the life of the unit:

▪Where the voltage fluctuates a lot

▪In vehicles or vessels

▪Where acidic or alkaline vapour is present

▪In places where a mineral oil mist, spray or vapour may be present in the atmosphere. Plastic parts may deteriorate and fall off or cause water leakage.

▪In places where the unit would be in the path of direct sunlight.

▪In bathrooms.

▪Sound sensitive areas (e.g. near a bedroom), so that the operation noise will cause no trouble.
