Installation of outdoor unit
Try to bring the packed unit to the installation place.
When it is inevitable to unpack the unit, be careful not to damage the unit.
Wrap it with nylon etc.
After unpacking, be sure to put it with the front side of the unit facing up.
Note: When delivering, don't hold plastic
parts like inlet and outlet grill etc.
Selection of installation place
Place strong enough to support the unit and
will not cause vibration and noise.
Place where discharged wind and noise
doesn't cause a nuisance to the neighbors.
Place where is less affected by rain or direct
sunlight and is sufficiently ventilated, or to
install a shield.
Place with enough space for smooth air flow.
Fixing of the unit
Fix outdoor unit using M10 bolt to concrete floor horizontally.
If installed on the wall or on top of a roof, bracket should be fixed securely to
resist earthquake or storms.
Use rubber pad during installation against unit vibration.

Installation of indoor unit
Selection of installation place
Place where it is easy to route drainage pipe and outdoor piping.
Place away from heat source and with less direct sunlight.
Place where cool and warm air could be delivered evenly to every corner of the room.
Place near power supply socket. Leave enough space around the unit (refer to installation
drawings).
Fixing of the unit
1.Position of the wall hole
Wall hole should be decidedaccording to installtion placeand piping direction. (refer to
installation drawings)
2.Making a wall hole
Drill a hole of 70mm dia. with a little
slope towards outside.
Install piping hole cover and seal it
with putty after installation.

Piping connection
1.Connecting method
Apply refrigerant oil at half union and flare nut.
To bend a pipe, give the roundness as large as possible not to crash the pipe.
When connecting pipe, hold the pipe centre to centre then screw nut on by hand, refer
to Fig.
Be careful not to let sundries, such as sands enter the pipe.
2. Piping connection of indoor unit
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 wiring work.
Cut away, with a 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 connecting
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 hose through wall hole to
connect with outdoor unit.
