replaced by exclusive cable.
(3) After connecting the power cord, please fix the electric box cover properly in order to avoid accident.
(4) Never fail to comply with the nitrigen charge requirements.Charge nitrogen when welding pipes.
(5) Never short-circiut or cancel the pressure switch to prevent unit damage.
(6) Please firstly connect the wired controller before energization, otherwise wired controller can not be
used.
(7) Before using the unit, please check if the piping and wiring are correct to avoid water leakage, refrigerant
leakage, electric shock, or fire etc.
(8) Do not insert fingers or objects into air outlet/inlet grille.
(9) Open the door and window and keep good ventilation in the room to avoid oxygen deficit when the gas/oil
supplied heating equipment is used.
(10)Never start up or shut off the air conditioner by means of directly plug or unplug the power cord.
(11)Turn off the unit after it runs at least five minutes; otherwise it will influence oil return of the compressor.
(12)Do not allow children operate this unit.
(13)Do not operate this unit with wet hands.
(14)Turn off the unit or cut off the power supply before cleaning the unit, otherwise electric shock or injury
may happen.

2 Installation of Indoor Unit
Selection of Installation location.
(1). Such a place where cool air can be distributed throughout the room.
(2). Such a place where condensation water is easily drained out.
(3). Such a place that can handle the weight of indoor unit.
(4). Such a place which has easy access for maintenance.
(5). The appliance shall not be installed in the laundry.
There are 2 styles of installation.
(1). Wall mounted;
(2). Floor type.
Each type is similar to the other as follows;
2.1 Indoor Unit
The indoor unit should be sited in a place where:
(1). The restrictions on installation specified in the indoor unit installation drawings are met.
(2). Both air intake and exhaust have clear paths met.
(3). The unit is not in the path of direct sunlight.
(4). The unit is away from the source of heat or steam.
(5). There is no source of machine oil vapour (this may shorten indoor unit life).
(6). Cool (warm) air is circulated throughout the room.
(7). The unit is away from electronic ignition type fluorwscent lamps (inverter or rapid stert type)
as they may shorten the remote controller range.
(8). The unit is at least 1 metre away from any television or radio set (unit may cause
interference with the picture or sound).
Cautions for Installation where air conditioner troubleis liable tooccur.
·Where there is too much of oil area.
·Where it is acid base area.
·Where there is irregular electrical supply.
Indoor Unit Installation Drawings
The indoor unit may be mounted in any of the three styles shown here.

2.2 Refrigerant Piping
(1). Drill a hole (65mm (2-5/9in) in diameter ) in the spot indicated by О the symbol in the
illustration ad below.
(2). The location of the hole is different depending on which side of the pipe is taken out.
(3). For piping, see connecting the refrigerant pipe, under Indoor Unit Installation.
(4). Allow space around the pipe for a easier indoor unit pipe connection.
NOTICE! The suggested shortest pipe length is 2.5m(8-1/5ft),in order to avoid noise from
the outdoor unit and vibration.
Mechanical noise and vibration may occur depending on how the unit is installed and the
environment in which it is used.
Boring a wall hole and installing wall embedded pipe
For walls containing metal frame or metal board, be sure to use a wall embedded pipe and
wall cover in the feed-through hole to.
Be sure to caulk the gaps around the pipes with caulking material to prevent water leakage.
(1). Bore a feed-through hole of 65mm(2-5/9in) in the wall so it has a down slope toward the
outside.
(2). Insert a wall pipe into the hole.
(3). Insert a wall cover into wall pipe.
(4). After completing refrigerant piping, wiring, and drain piping, caulk pipe hole gap with putty.

Multi Variable Air Conditioners Console Type Indoor Unit

2.3 Drain Piping
(1). Use commercial regid polyvinyl chloride pipe general VP 20 pipe, outer diameter
26mm(1in), inner diameter 20mm(3/4in) for the drain pipe.
(2). The drain hose (outer diameter 18mm(7/10in) at connecting end, 220mm(8-2/3in) long)is
supplied with the indoor unit. Prepare the drain pipe picture below position.
(3). The drain pipe should be inclined downward so that water will flow smoothly without any
(Should not be trap.)
(4). Insert the drain hose to this depth so it won’t be pulled out of the drain pipe.
(5). Insulate the indoor drain pipe with 10mm(2/5in) or more of insulation material to prevent
condensation.
(6). Remove the air filters and pour some water into the drain pan to check the water flows
smoothly.
2.4 Installing Indoor Unit
2.4.1 Preparation
(1). Open the front panel, remove the 4 screws and dismount the front grille while pulling it
forward.
(2). Follow the arrows to disengage the clasps on the front case to remove it.
(3). Follow the procedure below when removing the slit portions.

Multi Variable Air Conditioners Console Type Indoor Unit

For Moldings:
Remove the pillars. (Remove the slit portions on the bottom frame using nippers.)
For Side Piping:
Remove the pillars.
(1). Remove the 7screws.
(2). Remove the upper casing (2 tabs).
(3). Remove the left and right casings (2 tabs on each side ).
(4). Remove the slit portions on the bottom frame and casings using nippers.
(5). Return by following the steps in reverse order (3>2>1).

Multi Variable Air Conditioners Console Type Indoor Unit

2.4.2 Installation
Secure using 6 screws for floor installations. (Do not forget to secure to the rear wall.)
For wall installations, secure the mounting plate using 5 screws and the indoor unit using 4
screws.
The mounting plate should be installed on a wall which can support the weight of the indoor
unit.
(1). Temporarily secure the mounting plate to the wall, make sure that the panel is completely
level, and mark the boringpoints on the wall.
(2). Secure the mounting plate to the wall with screws.
(3). Once refrigerant piping and drain piping connections are complete, fill in the gap of the
through hole with putty. A gap can lead to condensation on the refrigerant pipe, and drain
pipe, and the entry of insects into the pipes.
(4). Attach the front panel and front grille in their original positions once all connections are
complete.
Flaring the pipe end
(1). Cut the pipe end with a pipe cutter.
(2). Remove burrs with the cut surface facing downward so that the chips do not enter the
pipe.
(3). Fit the flare nut on the pipe.

Multi Variable Air Conditioners Console Type Indoor Unit
8
(4). Flare the pipe.
(5). Check that the flaring is properly made.
1DO not use mineral oil on flared part.
2 Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
3 Never use piping which had been used for previous installations. Only use parts which are delivered with the
unit.
4 Do never install a drier to this R410A unit in order to guarantee its lifetime.
5 The drying material may dissolve and damage the system.
6 Incomplete flaring may cause refrigerant gas leakage.
Connecting the refrigerant pipe:
(1). Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts
and gas leaks.
(2). Align the centres of both flares and tighten the flares and tighten the flare nuts 3 or 4 turns
by hand. Then tighten them fully with the torque wrenches.
(3). To prevent gas leakage, apply refrigeration oil on both inner and outer surfaces in the flare.
(Use refrigeration oil for R410A.)

Caution on piping handling:
(1). Protect the open end of the pipe against dust and moisture.
(2). All pipe bends should be as gentle as possible. Use a pipe bender for bending.
(Bending radius should be 30 to 40mm (1-1/5in to 1-4/7in) or larger.)

Selection of copper and heat insulation materials:
When using commercial copper pipes and fittings, observe the following:
(1). Insulation material: Polyethylene foam
Heat transfer rate:0.041 to 0.052W/mK(0.035 to 0.045kca/(mh℃)
Refrigerant gas pipe’s surface temperature reaches 110℃（230℉） max.
Choose heat insulation materials that will withstand this temperature.
(2). Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as
below.

(2). See the sections on air purges and gas leak checks in the installation manual for the
outdoor unit.
Attaching the connection pipe
Attach the pipe after checking for gas leakage, described above.
(1). Cut the insulated portion of the on-site piping, matching it up with the connecting portion.
(2). Secure the slit on the refrigerant piping side with the butt joint on the auxiliary piping using
the tape, making sure there are no gaps.
(3). Wrap the slit and butt joint with the included insulation sheet, making sure there are no
gaps.
