2) Indoor Unit installation
¥L
The mounting floor should be strong and solid
enough to prevent it from vibration.
¥M
Drill the piping hole with 70mm diameter hole-core
drill at either the right or the left of indoor unit. The
hole should be sightly slant to the outdoor side.
¥N
Insert the plastic tube through the hole.
¥O
Cut the extruded outside part of the plastic tube, if
necessary.
3) Outdoor unit Installation
¥L
Install the outdoor unit on the concrete or any solid
base securely and horizontally by securing it with
bolts (Ø12mm) and nuts.
¥M
If there is any vibration transmitted to the building,
mount the rubber underneath the outdoor unit.
4) Refrigerant amount
Before shipment, this air conditioner is filled with the
rated amount of refrigerant including additional
amount required for air-purging, subject to 5m piping
length. (The rated amount of refrigerant is indicated
on the name plate.) But when the piping length
exceeds 5 meters, additional charge is required
according to the following table.
(Unit: g)
Example)  In case of 10m long pipe(one-way), the
amount of refrigerant to be replenished is:
(10 - 5) x 70 = 350g

parts of both indoor and outdoor unit, onto the 
copper pipes.
3
Pipe bending
To reduce the flow resistance of refrigerant.
4
Connection of installation parts
Connection of long piping
(elbows, socket etc)
5
Tighten the flare nut (outdoor) 
Connecting the pipings of the outdoor unit.
6
Blowing the pipings
To remove dust and scale in working.
7
Tighten the flare nut (indoor)
Connecting the pipings of the indoor unit.
8

3-way (gas side) valves.
11
Form the pipings
To prevent heat loss and sweat
12
Checking the drainage (indoor unit) 
To ensure if water flows drain hose of indoor unit.
13
Connecting the cable between outdoor and 
Preparation of the operating
indoor unit 
14
