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

(i.e., the cylinder is marked with

"Liquid filling siphon attached")

Charge with the cylinder upright.

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.

1.3.4 Brine

If applicable. See the installation manual or installer reference guide

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:

▪ 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.
