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

◆ The air conditioner should be used only for the applications for which it has been designed : the indoor unit is not

suitable to be installed in areas used for laundry. 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 will be respected.

◆ 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 page 8.

◆ Make sure that the water dripping from the drain hose runs away correctly and safely.

◆ 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.

◆

More than 2 indoor units should be installed when you use Free Joint Multi air conditioner.

◆ Our units must be installed in compliance with the spaces indicated in the installation manual to ensure either
accessibility from both sides or ability to perform routine maintenance and repairs.

The units’ components must be accessible and that can be disassembled in conditions of complete safety either for
people or things. For this reason, where it is not observed as indicated into the Installation Manual, the cost
necessary to reach and repair the unit (in safety, as required by current regulations in force) with slings, trucks,
scaffolding or any other means of elevation won’t be considered in-warranty and charged to end user.

◆

With an outdoor unit having net weight upper than 60kg, we suggest do not install it suspended on wall,

but considering floor standing one.

Checking gas leakage

www.keveklima.hu

Before completing the installation (insulation of the cables, hose and piping and xing of the indoor unit to
the installation plate), you must check that there are no gas leaks.

LEAK TEST WITH NITROGEN (before opening valves)

In order to detect basic refrigerant leaks, before recreating the vacuum and
recirculating the R-410A, it’s responsible of installer to pressurize the whole system
with nitrogen (using a cylinder with pressure reducer) at a pressure above 30 bar
(gauge).

LEAK TEST WITH R-410A (after opening valves)
Before opening valves, discharge all the nitrogen into the system and create vacuum

according to page 10.
After opening valves, check leaks using a leak detector for refrigerant.

occur and cause fire and if the terminal is connected too firmly, terminal may get damaged.

Method for connecting wires

Checking correct earthing

If the power distribution circuit does not have an earth or the earth does not comply with specifications, an
earthing electrode must be installed. The corresponding accessories are not supplied with the air conditioner.

1.

Select an earthing electrode that complies with the specifications
given in the illustration opposite.

Determine a suitable location for the earthing electrode :

2.

◆ 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.

3.

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.

4.

Install a green/yellow insulated earthing wire (Ø1.6 mm, section 2 mm² 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.j

5.

Carefully check the installation, by measuring the earthing resistance
with an earthing resistance tester. If the resistance is above the required
level(Example:100Ω), drive the earthing electrode deeper into the ground
or increase the number of earthing electrodes.

6.

Connect the earthing wire to the earthing screw on the air conditioner.
