3 Removal Of Air From The Pipe And Gas Leakage Inspection
Procedures of using Vacuum Pump for Air Removal
As shown in figure on the right, remove the cap of valve head and valve core
1and then connect them to the vacuum
pump and sub-division valve.
REMOVAL | | Fully tighten the “Hi” shuttle of the sub- |
| |
| | division valve and completely unscrew |
| 2 | the “Lo” shuttle. Run the vacuum pump |
| for about 10–15 minutes, then completely |
| |
| | tighten the “Lo” shuttle and switch off |
| | the vacuum pump. |
AIR | | Completely unscrew the spindle of the |
| |
3 service valve (at 2 places) in anti- clockwise direction to allow the flow of coolant (using Allen key).

Detail of cutting the connecting cord
To remove the connecting wires for the indoor unit, please remove the low cover panel in front of the unit.
!WARNING
●The naked part of the wire core should be 10 mm and fix it to the terminal tightly. Then try to pull the individual wire to check if the contact is tight. Improper insertion may burn the terminal.
●Be sure to use only power cables approved from the authorities in your country. For example in Germany: Cable type: NYM 3x1.5mm2, (fuse = 20A time delay)
●Please refer to the installation manual for wire connection to the terminals of the units. The cabling must meet the standards of electrical installation.
●There is a AC voltage of 220V between the L and N terminals. Therefore, before servicing, be sure to remove the plug from the AC outlet or switch off the main switch.

FINAL STAGE OF INSTALLATION
1Insulation And Maintenance Of Pipe Connection
●The connected terminals should be completed sealed with heat insulator and then tied up with rubber strap.
●Please tie the pipe and power line together with plastic tape as shown in the figure of installation of both the indoor and outdoor units. Then fix their position with holders.
●To enchance the heat insulation and to prevent water condensation, please cover the outdoor part of the drain hose and pipe with insulation pipe.
●Completely seal any gap with putty.

2Installation Of Remote Control
●The remote controller can be placed in its holder which is fixed on wall or beam.
●To operate the remote controller at its holder, please ensure that the unit can receive signal transmitted from the controller at the place where the holder is to be fixed. The unit will beep when signal is received from the remote controller. The signal transmission is weaken by the florescent light. Therefore, during the installation of the remote control holder, please switch on the light, even during day time, to determine the mounting location of the holder.
The controller should be insert from top into bottom side of the holder as shown in figure below.

3Earth Line And Circuit Breaker
!CAUTION
●The earth line terminal of the outdoor unit is below the service valve.
●To avoid short circuit, it is necessary to install circuit breaker depending on the mounting location of the unit.
●Do not place earth line near the following objects:
(1)Water pipe
(2)Gas pipe – There is danger of catching fire.
(3)The earth line of lightning conductor and telephone — short circuit may occur during lightning.
4Power Source And Operation Test
Power Source
!WARNING
●Do not alter the plug of power cord.
Do not make extension to the power cord.
!CAUTION
●Please use a new socket. Accident may occur due to the use of old socket because of poor contact.
●Please plug in and then remove the plug for 2 – 3 times. This is to ensure that the plug is completely plugged into the socket.
●Keep additional length for the power cord and do not render the plug under external force as this may cause poor contact.
●Do not fix the power cord with U-shape nail.
Operation Test
●Please ensure that the air conditioner is in normal operating condition during the operation test.
●Explain to your customer the proper operation procedures as described in the user’s manual.
