(Gas piping connection) While the main gas side pipe is ø25.4, since connecting the outdoor unit's 3-way valve requires a ø19.05
fl are, please be sure to use standard accessories joint piping B or A for connection (brazing), and connect as follows.
1. Since standard accessory joint piping B comes supplied for connecting the outdoor unit's 3-way valve, machine the upper
edge to ø19.05 flare specifi cations.
2. Refer to connection pipe process examples (1) - (4) to cut the joint piping A to the necessary length.
3. Braze the machined (cut) joint piping A to the bottom edge of joint piping B.
4. In order to protect wiring and parts in the unit, please carry out brazing outside the unit (since each type of joint piping is
differently oriented, carry out brazing according to the orientations shown in the connection pipe process diagrams.
5. Connect the brazed connection pipes to the outdoor unit's 3-way valve through the fl are connection.
When cutting the pipe, use a pipe cutter and be sure to carry out deburring.
Ensure that water, sand etc. do not enter the interior of the piping.
Using a fl are tool, carry out sound fl are process.

8. SELECTING THE INSTALLATION SITE
Type E2
Indoor Unit
AVOID:
Areas where leakage of flammable gas may be expected.
Places where large amounts of oil mist exist.
Direct sunlight.
Locations near heat sources which may affect the performance of the unit.
Locations where external air may enter the room directly. This may cause “condensation” on the air-discharge
ports, causing them to spray or drip water.
Locations where the remote controller will be splashed with water or affected by dampness or humidity.
Installing the remote controller behind curtains or furniture.
Locations where high-frequency emissions are generated.
Places where blocks air passages.
Places where the false ceiling is not noticeably on an incline.
DO:
Select an appropriate position from which every corner of the room can be uniformly cooled.
Select a location where the ceiling is strong enough to support the weight of the unit.
Select a location where tubing and drain pipe have the shortest run to the outdoor unit.
Allow room for operation and maintenance as well as unrestricted airflow around the unit.
Install the unit within the maximum elevation difference above or below the outdoor unit and within a total tubing
length (L) from the outdoor unit as detailed in Table 1-1.
Allow room for mounting the remote controller about 1 m off the floor, in an area that is not in direct sunlight or in
the flow of cool air from the indoor unit.
Places where optimum air distribution can be ensured.
Places where sufficient clearance for maintenance and service can be ensured.
When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs. Do not
exert any pressure on other parts, especially the refrigerant piping, drain piping and flange parts.
If you think the humidity inside the ceiling might exceed 30°C and RH 80%, reinforce the insulation on
the unit body. Use glass wool or polyethylene foam as insulation so that it is no thicker than 10 mm and
fits inside the ceiling opening.
