HSU-138HEA03-S
Fix the unit to concrete or block with bolts( 10mm) and nuts firmly and horizontally.
When fitting the unit to wall surface, roof or rooftop, fix a supporter surely with nails
or wires in consideration of earthquake and strong wind.
If vibration may affect the house, fix the unit by attaching a vibration-proof mat.
Indoor Unit
Place, robust not causing vibration, where the body can be supported
sufficiently.
Place, not affected by heat or steam generated in the vicinity, where
inlet and outlet of the unit are not disturbed.
Place, possible to drain easily, where piping can be connected with the
outdoor unit.
Place, where cold air can be spread in a room entire
Place, nearby a power receptacle, with enough space around. (Refer
to drawings).
Place where the distance of more than lm from televisions, radios,
wireless apparatuses and fluorescent lamps can be left.
In the case of fixing the remote controller on a wall, place where the
indoor unit can receive signals when the fluorescent lamps in the room
are lightened.
Selection of Installation Place
ly.

Outdoor Unit
Place, which is less affected by rain or direct sunlight and is
sufficiently ventilated.
Place, possible to bear the unit, where vibration and noise are
not increased.
Place, where discharged wind and noise do not cause a
nuisance to the neighbors.
Place, where a distance marked is available as illustrated
in the above figure.
Power Source
Before inserting power plug into receptacle, check the voltage without fail. The power source is the same as the corresponding name plate.
Install an exclusive branch circuit of the power.
A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable by cutting it.
Selection of pipe
To this unit, both liquid and gas pipes shall be insulated
as they become Iow temperature in operation.
Use optional parts for piping set or pipes covered with
equivalent insulation material.

1.Fitting of the Mounting Plate and Positioning of the wall Hole
When the mounting plate is first fixed
1.Carry out, based on the neighboring pillars or lintels, a proper leveling for the plate to be
fixed against the wall, then temporarily fasten the plate with one steel nail.
2. Make sure once more the proper level of the plate, by hanging a thread with a weight from
the central top of the plate, then fasten securely the plate with the attachment steel nail.
3. Find the wall hole location A using a measuring tape
B= 60mm
A=145mm

When the mounting plate is fixed side bar and lintel
Fix to side bar and lintel a mounting bar, Which is separately sold, and then fasten
the plate to the fixed mounting bar.
Refer to the previous article, " When the mounting plate is first fixed ", for the
position of wall hole.
2.Making a Hole on the Wall and Fitting the Piping Hole Cover
Make a hole of 60 mm in diameter,
slightly descending to outside the wall.
Install piping hole cover and seal it
off with putty after installation

Drawing of pipe
[ Rear piping ]
Draw pipes and the drain hose, then fasten them with the adhesive tape
[ Left Left-rear piping ]
In case of left side piping, cut away, with a nipper, the lid for left piping.
In case of left-rear piping, bend the pipes according to the piping direction to the mark of hole for left-rear
piping which is marked on heat insulation materials.

1. Insert the drain hose into the dent of heat insulation materials of indoor unit.
2. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then
connect them.
3. Coat the flaring seal face with refrigerant oil and connect pipes.

When connecting the cable before installing the indoor unit
Insert the cable from the back side of the unit, then pull it out on the front side.
Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws.
Pull the cable slightly to make sure the cables have been properly inserted and tightened.
After the cable connection, never fail to fasten the connected cable with the wiring cover.
Note: When connecting the cable, confirm the terminal number of indoor and outdoor units carefully. If wiring
is not correct, proper operation can not be carried out and will cause defect.
Connecting the indoor/outdoor Electric Cable
Removing the wiring cover
Remove terminal cover at right bottom corner of indoor unit, then
take off wiring cover by removing its screws.
When connecting the cable after installing the indoor unit
1. Insert from outside the room cable into left side of the wall hole, in which
the pipe has already existed.
2. Pull out the cable on the front side, and connect the cable making a loop.
2. If the fuse of indoor unit on PC board is broken, please change it with the type of T. 3.15A/250V.
3. The wiring method should be in line with the local wiring standard.
4. After installation, the power plug should be easily reached.
5.
A breaker should be incorporated into fixed wiring. The breaker should be all-pole switch and the
distance between its two contacts should be not less than 3mm.

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 90
hexagon wrench, and after approx.
10 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.
