Safety Precautions
The following safety precautions must be taken when using your air conditioner.
WARNING
I NSTALLING THE UNIT
Risk of electric shock.
•
Can cause injury or death.
•
Disconnect all remote electric power supplies before servicing, installing or cleaning.
•
This must be done by the manufacturer or its service agent or a similar qualified person in order to avoid a hazard.
◆ The unit should not be installed by the user. Ask the dealer or authorized company to install the units except room air conditioners for the U.S.A and
Canada area.
◆ If the unit is installed improperly, water leakage, electric shock or fire may result.
◆ The air conditioner must be installed in accordance with national wiring regulations and safety regulations wherever applicable.
◆ Mount with the lowest moving parts at least 2.5 m above the floor or grade level. (If applicable)
◆ The manufacturer does not assume responsibility for accidents or injury caused by an incorrectly installed air conditioner. If you are unsure about installation, contact an installation specialist.
◆ When installing the built-in type air conditioner, keep all electrical cables such as the power cable and the connection cord in pipe, ducts, cable channels e.t.c to protect them against liquids, outside impacts and so on.
P
OWER SUPPLY LINE
,
FUSE OR CIRCUIT
BREAKER
◆ If the power cord of this air conditioner is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
◆ The unit must be plugged into an independent circuit if applicable or connect the power cable to the auxiliary circuit breaker. An all pole disconnection from the power supply must be incorporated in the fixed wiring with a contact opening of >3mm.
◆ Do not use an extension cord with this product.
◆ If the unit is equipped with a power supply cord and a plug, the plug must be accessible after installation.
◆ This appliance must be installed accordance with the national wiring regulations.

Deciding on Where to Install the Air Conditioner
When deciding on the location of the air conditioner with the owner, the following restrictions must be taken into account.
General
Do NOT install the air conditioner in a location where it will come into contact with the following elements:
◆ Combustible gases
◆ Saline air
◆ Machine oil
◆ Sulphide gas
◆ Special environmental conditions
If you must install the unit in such conditions, first consult your dealer.
Outdoor Unit
◆ The outdoor unit must NEVER be placed on its side or upside down, as the compressor lubrication oil will run into the cooling circuit and seriously damage the unit.
◆ Choose a location that is dry and sunny, but not exposed to direct sunlight or strong winds.
◆ Do not block any passageways or thoroughfares.
◆ Choose a location where the noise of the air conditioner when running and the discharged air do not disturb any neighbours.
◆ Choose a position that enables the piping and cables to be easily connected to the indoor unit and the recommended length of 7.5 metres to be respected. (1 Unit)
◆ Install the outdoor unit on a flat, stable surface that can support its weight and does not generate any unnecessary noise and vibration.
◆ Position the outdoor unit so that the air flow is directed towards the outside, as indicated by the arrows on the top of the unit.
◆ Maintain sufficient clearance around the outdoor unit, as indicated in the diagram on the page opposite.
◆ If the outdoor unit is installed at a height, ensure that its base is firmly fixed in position; the maximum height is
7 metres.
◆ Make sure that the water dripping from the drain hose runs away correctly and safely.
C A U T II II O N
◆ You have just purchased a Free Joint Multi air conditioner and it has been installed by your installation specialist.
◆ This device must be installed according to the national electrical rules.
◆ Max input power & current is measured according to IEC standard and input power & current is measured according to ISO standard.

Insert the drain plug into the drain hole on the underside of the outdoor unit.
Connect the drain hose to the drain plug.
3 Ensure that the drained water runs off correctly and safely.
Cutting/Extending the Piping
1
2
Make sure that you have the required tools available (pipe cutter, reamer, flaring tool and pipe holder).
If you wish to shorten the piping, cut it using a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle with the side of the pipe, and referring to the illustrations below for examples of edges cut correctly and incorrectly.

Select an earthing electrode that complies with the specifications given in the illustration opposite.
Determine a suitable location for the earthing electrode:
◆ In damp hard soil rather than loose sandy or gravel soil that has a higher earthing resistance
◆ Away from underground structures or facilities, such as gas pipes, water pipes, telephone lines and underground cables
◆ At least two meters away from a lightening conductor earthing electrode and its cable
➢ The earthing wire for the telephone line cannot be used to earth the air conditioner.
Dig a hole of the size indicated in the illustration opposite, drive the earthing electrode into position and cover the top of the electrode with the excavated soil.
Install a green/yellow insulated earthing wire (Ø1.6 mm, section 2 mm 2 or greater):
◆ If the earthing wire is too short, connect an extension lead, soldering the connection and wrapping it with insulating tape (do not bury the soldered connection)
◆ Secure the earthing wire in position with staples
➢ If the earthing electrode is installed in an area of heavy traffic, its wire must be connected securely.
Carefully check the installation, by measuring the earthing resistance with an earthing resistance tester. If the resistance is above the required level(Example:100
Ω
), drive the earthing electrode deeper into the ground or increase the number of earthing electrodes.
Connect the earthing wire to the earthing screw on the air conditioner.

The air in the indoor unit and in the pipe must be purged. If air remains in the refrigeration pipes, it will affect the compressor, reduce to cooling/heating capacity and could lead to a malfuction. Refrigerant for air purging is not charged in the outdoor unit.
Use Vacuum Pump as shown at the right figure. Each unit must be purged in turn.

Check the piping connections.
Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port (3/8 ” service valve) as shown at the figure.
Open the valve of the low pressure side of manifold gauge counter-clockwise.
Purge the air from the system using vacuum pump for about 10 minutes.
- Close the valve of the low pressure side of manifold gauge clockwise.
- Make sure that pressure gauge show -0.1MPa(-76cmHg) after about
10 minutes.
This procedure is very important in order to avoid gas leak.
- Turn off the vacuum pump
- Remove the hose of the low pressure side of manifold gauge.
Set valve cork of both liquid side and gas side of packed valve to the open position.
Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf•cm with a torque wrench.
Check for gas leakage.
- At this time, especially check for gas leakage from the 3-way valve’s stem nuts, and from the service port cap.

Connect the charging hose of low pressure side of manifold gauge to the packed valve having a service port (5/8 ” Packed valve) as shown at the figure (Value stem : 1/2 ” - 20UNF).
Open the valve of the low pressure side of manifold gauge counter clockwise.
Purge the air from the system using vacuum pump for about 30 minutes.
- Close the valve of the low pressure side of manifold gauge clockwise.
- Make sure that pressure gauge show -0.1MPa(-76cmHg) after about
30 minutes.
This procedure is very important in order to avoid gas leak.
- Turn off the vacuum pump.
- Remove the hose of the low pressure side of manifold gauge.
Set valve cork of both liquid side and gas side of packed valve to the open position.
Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf•cm with a torque wrench.
Check for gas leakage.
- At this time, especially check for gas leakage from the 3-way valve’s stem nuts, and from the service port cap.
