7.1 The Procedure of Connecting Pipes
Four dierent conguration are available for oudoor unit only
changing the panels and fan position.
CAUTION
All eld piping must be provided by a licensed refrigeration
technician and must comply with the relevant local and
national codes.
Do not let air, dust, or other impurities fall in the pipe system
during the time of installation.
The connecting pipe should not be installed until the indoor
and outdoor units have been xed already.
Keep the connecting pipe dry, and do not let moisture in during
installation.
Execute heat insulation work completely on both sides of the
gas piping and the liquid piping. Otherwise, this can sometimes
result in water leakage.
Drill a hole in the wall (suitable just for the size of the wall
conduit), then set on the ttings such as the wall conduit and
its cover.
Bind the connecting pipe and the cables together tightly with
binding tapes.Pass the bound connecting pipe through the
wall conduct from outside. Be careful of the pipe allocation to
do on damage to the tubing.
Connect the pipes. Refer to "How to Connect the pipes" for
details.
Expel the air with a vacuum pump. Refer to "How to expel the
air with a vacuum pump" for details.
Open the stop values of the outdoor unit to make the
refrigerant pipe connecting the indoor unit with the outdoor
unit in uent ow.
Check the leakage. Check all the joints with the leak detector
or soap water.
Cover the joints of the connecting pipe with the soundproof /
insulating sheath (ttings), and bind it well with the tapes to
prevent leakage.

CAUTION
Be sure to with insulating materials cover all the exposed parts of
the are pipe joints and refrigerant pipe on the liquid-side and the
gas-side. Ensure that there is no gap between them.
Incomplete insulation may cause water condensation.
How to Connect the pipes
Flaring
Cut a pipe with a pipe cutter. (Refer to Fig.7-1)
Insert a are nut into a pipe and are the pipe.

How to expel the air with a vacuum pump
Stop valve operation introduction
Opening stop valve.
Remove the cap and turn the valve counter clock-wise with the
hexagon wrench.
Turn it until the shaft stops.Do not apply excessive force to the
stop valve. Doing so may break the valve body, as the valve is
not a backseat type. Always use the special tool.
Make sure to tighten the cap securely.
Closing stop valve
Remove the cap and turn the valve clockwise with the hexagon
wrench.
Securely tighten the valve until the shaft contacts the main
bodyseal.

Loosen and remove the maintenance nuts of stop valves A and
B, and connect the charge hose of the manifold valve to the
service port of stop valve A. (Be sure that stop valves A and B
are both closed)
Connect the joint of the charge hose with the vacuum pump.
Open the Lo-lever of the manifold value completely.
Turn on the vacuum pump. At the beginning of pumping,
loosen the maintenance nut of stop valve B a little to check
whether the air comes in (the sound of the pump changes,
and the indicator of compound meter turns below zero). Then
fasten the maintenace nut.
When the pumping has nished, close the Lo-lever of the
manifold valve completely and turn o the vacuum pump.Make
pumping for 15 minutes or more and check that the compound
meter indicates -76cmHg(-1X105Pa)
Loosen and remove the cap of stop valves A and B to open stop
valve A and B completely, then fasten the cap.
Disassemble the charge hose from the service port of stop
valve A, and fasten the nut.

completed.
Refrigerant may only be charged after performing the leak test
and the vacuum pumping.
When charging a system, care shall be taken that its maximum
permissible charge is never exceeded, in view of the danger of
liquid hammer.
Charging with an unsuitable substance may cause explosions
and accidents, so always ensure that the appropriate refrigerant
is charged.
Refrigerant containers shall be opened slowly.
Always use protective gloves and protect your eyes when charging
refrigerant.
The outdoor unit is factory charged with refrigerant. Calculate
the added refrigerant according to the diameter and the
length of the liquid side pipe of the outdoor unit/indoor unit
connection. (suitable for throttle outdoor unit)
