3. Piping connection
Connecting method
To bent a pipe, give the roundness as large as possible not to crash the pipe.
When connecting pipe, hold the pipe center to center then screw nut on by hand, refer to Fig.
Be careful not to let foreign matters, such as sands enter the pipe.
Piping connection of the indoor unit
1. Arrangement of piping and drainage pipe
Cut away, with hammer or a saw, the lid for piping according to piping direction.
According to the piping method, connect the piping on indoor unit with union of connection pipe.
Arrange the piping as per the wall hole and bind drain hose connecting electric cable and piping
together with polyethylene tape.
Insert the bound piping connecting electric cable and drain hoes through wall hole to connect
with outdoor unit.
2. Arrangement drain hose
Drain hose shall be placed in under place.
There should be a slope when arrange drain hose. Avoid up and down waves in drain hose.
If humidity is high, drain pipe(especially in room and indoor unit) must be covered with
installation material.
After opening inlet grill, you will see a control
box as shown in the Fig.
Remove the cover before working.

1. Piping connection of the outdoor unit
Connecting the connecting pipe and inlet and
outlet liqued pipe according to the piping method.
Purging Method:
Push the air out of the indoor unit
and piping as followes:
(1) Remove the valve cap on 2-way
valve in outdoor unit.
(2) Loosen by 1/2 turn the flare nut of
gas pipe, which is conneted to
3-way valve.
(3) Loosen 2-way valve by 90o using
hexagon wrench, and after approx.
6 sec tighten it up. Gas comes out
through flare nut on wide pipe. If no
gas is discharged, tighten flare nut
with specified torque.
(4) Open 2-way and 3-way valves
using specified torque.
(5) Tighten the caps on the valves
with specified torque.

Note: When extending piping, air inside piping shall be removed by using external refrigerant gas,
charge according to the following list.
Brand new outdoor unit is charged 50g or 80g(22k,24k) more refrigerant than regulated weight. Only for
first installation, this extra 50g or 80g(22k,24k) can be used to purge airin pipes.
During this procedure, 50g or 80g(22k,24k) refrigerant will be discharged in piping.(This must be
strictly controlled within 90o and 10 sec.)
CAUTION
In case more than 5m
Oil trap shoud be installed every 5~7m
Max. Length: for 7K 9K : A=7m
for 12K: A=10m
for 18K 22K 24K: A=20m
Max.Elevation:
for 7K 9K 12K: 5m
for 18K 22K 24K: 10m
no more gas if the length of connecting pipe is less than
7m(
• •7K 9K
)
• •
or 10m(12K) or 20m(18K 22K 24K).
The height difference between any two indoor or outdoor units can not be
more than 5m(7K 9K 12K ) or 10m(18K 22K 24K).

Note: When additional refrigerant is necessary, first purge air out of connecting pipe by external gas,
then drive out the excessive rerigerant by purging method.
Brand new unit is charged 80g more refrigerant than spec. This is only for first instaltion to purge air
in the indoor unit and connecting pipe.
When piping is longer than 5m, charge additional refrigerant specified in this list.

Electric wiring
Note:
Electric wiring must be done by qualified person.
Use copper wire only.
The parameter of the connecting cable:
Wiring of indoor unit
Insert the cable from outside the wall hole where piping already exist.
Pull it out from front.
Losen terminal screw and insert cable end fully into terminal block, then
Pull the cable gently to make sure it is tight.
Replace cover after wiring.
Wiring of outdoor unit
Insert the cable from inside the wall hole where piping already exist.
Pull it out from front.
Loose terminal screw and insert cable end fully into terminal block, then tighten it
Pull the cable gently to make sure it is tight.
Replace cover after wiring.
When connecting indoor and outdoor wire, check the number on indoor and outdoor terminal
blocks. Terminals of same number and same color shall be connected by the same wire.
Incorrect wiring may damage air conditioner's control or cause operation failure.
Note:
tighten it

When installation air conditoner in a wet place, try to use a circuit breaker against Current
leakage.
For installation in other palces, use circuit breaker as far as possible.
2. Piping cutting and flaring
Be sure to carry out deburring after cutting with a pipe cutter.
Insert flaring tool to make a flare.
Installation inspection and test run:
Please operate unit according to this Manual.
Items to be checked during test run. Please made a '' '' in '' ''
