Purging air and checking gas leakage
WARNING
◆ When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before
removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the
service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may
cause explosion and injury.
Purging air
1 Check the piping connections.
2 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).
WARNING
◆ Make the electrical connection and leave the system into “stand
by mode”. Do not turn on the system! This is necessary for better
vacuum operation (full OPEN position of Electronic Expansion
Valve - EEV -).
3 Open the valve of the low pressure side of manifold gauge
counter clockwise.
4 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.

Checking gas leakage
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.
Important information regarding the refrigerant use
This product contains fluorinated greenhouse gases. Do not vent
gases into the atmosphere.
CAUTION :

Pumping down refrigerant
WARNING
◆ After installing the product, be sure to perform leak tests on the piping
connections. After pumping down refrigerant to inspect or relocate the outdoor
unit, be sure to stop the compressor and then remove the connected pipes.
- Do not operate the compressor while a valve is open due to refrigerant leakage
from a pipe or an unconnected or incorrectly connected pipe. Failure to do so
may cause air to flow into the compressor and too a high pressure to develop
inside the refrigerant circuit, leading to an explosion or product malfunction.
Pump-down is an operation intended to collect all the system refrigerant in the outdoor unit.
This operation must be carried out before disconnecting the refrigerant pipe in order to
avoid refrigerant loss to the atmosphere.
1. Turn the system on in cooling with fan operating at high velocity and then let the
compressor run for more than 5 minutes. (Compressor will immediately start, provided 3 minutes have elapsed since the last stop.)
2. Release the valve caps on High and Low pressure side.
3. Use L-wrench to close the valve on the high pressure side.
4. After approximately 2 minute, close the valve on the low pressure side.
5. Stop operation of the air conditioner by pressing the (Power) button on the indoor
unit or remote control.
6. Disconnect the pipes.

䭭
Connect the cables to the terminal board using the compressed ring terminal.
Use rated cables only.
Connect the cables with driver and wrench that can apply the rated torque to the screws.
Make sure that appropriate tightening torque is applied for cable connection. If the terminal is loose, arc heat may
occur and cause fire and if the terminal is connected too firmly, terminal may get damaged.

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.
Select an earthing electrode that complies with the specifications
given in the illustration opposite.
2.
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.
䭭 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.
