(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
(4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation, close the
low-pressure knob on the vacuum pump coupling. Stop
the vacuum pump.
(6) Open the 2-way valve by 1/4 turn and then close it
after 10 seconds.Check all the joints for leaks using
liquid soap or an electronic leak device.
(7) Turn the body of the 2-way and 3-way valves. Disconnect the vacuum pump hose.
(8) Replace and tighten all the caps on the valves.

Fig.4.2 shows the installation steps of the wired controller, but there are some issues that need
your attention.
1) Prior to the installation, please firstly cut off the power supply of the wire buried in the
installation hole, that is, no operation is allowed with electricity during the whole installation.
2) Pull out the four-core twisted pair line from the installation holes and then let it go through
the rectangular hole behind the soleplate of the wired controller.

4) Insert the four-core twisted pair line into the slot of the wired controller and then buckle the
front panel and the soleplate of the wired controller together.
CAUTION!
Please pay special attention to the followings during the connection to avoid the malfunction of
the air conditioning unit due to electromagnetic interference.
ķ . Separate the signal and communication lines of the wired controller from the power cord

Fig.4.2
Fig.4.2 shows the installation steps of the wired controller, but there are some issues that need
your attention.
1) Prior to the installation, please firstly cut off the power supply of the wire buried in the
installation hole, that is, no operation is allowed with electricity during the whole installation.
2) Pull out the four-core twisted pair line from the installation holes and then let it go through
the rectangular hole behind the soleplate of the wired controller.
with screws M4X25.
4) Insert the four-core twisted pair line into the slot of the wired controller and then buckle the
front panel and the soleplate of the wired controller together.
CAUTION!
Please pay special attention to the followings during the connection to avoid the malfunction of
the air conditioning unit due to electromagnetic interference.
ķ . Separate the signal and communication lines of the wired controller from the power cord

and connection lines between the indoor and outdoor unit, with a minimum interval of 20cm,
otherwise the communication of the unit will probably work abnormally.
ĸ . If the air conditioning unit is installed where is vulnerable to electromagnetic
interference,then the signal and communication lines of the wired controller must be the shielding
twisted pair lines.
