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.

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.

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.

Installer reference guide

1 General safety precautions

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.

1.2.4 Brine

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.

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:

1.2.5 Water

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.

1.2.6 Electrical

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.

▪ 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.

CAUTION

▪ Check if the installation location can support the unit's

weight. Poor installation is hazardous. It can also cause vibrations or unusual operating noise.

▪ Provide sufficient service space.

▪ Do NOT install the unit so that it is in contact with a

ceiling or a wall, as this may cause vibrations.

▪ Choose a location where the hot/cold air discharged from the unit

or the operation noise, will NOT disturb anyone.

▪ Provide sufficient space around the unit for servicing and air

circulation.

▪ Avoid areas where flammable gas or product might leak.

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.

WARNING

Do NOT place objects below the indoor and/or outdoor unit that may get wet. Otherwise condensation on the unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, and objects under the unit may get dirty or damaged.

WARNING

The appliance shall be stored in a room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater).

NOTICE

▪ Do NOT stack the units on each other.

▪ Do NOT hang the unit on a ceiling.

Strong winds (≥18 km/h) blowing against the outdoor unit’s air outlet causes short circuit (suction of discharge air). This may result in:

▪ deterioration of the operational capacity;

▪ frequent frost acceleration in heating operation;

▪ disruption of operation due to decrease of low pressure or

increase of high pressure;

▪ a broken fan (if a strong wind blows continuously on the fan, it

may start rotating very fast, until it breaks).

It is recommended to install a baffle plate when the air outlet is exposed to wind.

It is recommended to install the outdoor unit with the air inlet facing the wall and NOT directly exposed to the wind.
