place and piping direction.(refer to installation drawings).
2. Making a wall hole
Drill a hole of 70X70mm dia. with a little slope towards
outside.

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
After opening inlet grill, you will see a control
box as shown in the Fig.
Remove the cover before working.
Cut
away, with hammer or a saw, the lid for piping according to piping direction.
Drain hose
Copper tube
Insulation material
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.

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.

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 90

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.
