Outdoor Unit

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.

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 entirely.

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.

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.

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.

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.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

Refer to the previous article, " When the mounting plate is first fixed ", for the

position of wall hole.

Fix to side bar and lintel a mounting bar, Which is separately sold, and then fasten

the plate to the fixed mounting bar.

Make a hole of 60 mm in diameter,

slightly descending to outside the wall.

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.

Fixing the indoor unit body

[Other direction piping]

Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape.

Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according

to the position of wall hole. When bending, be careful not to crash pipes.

Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation

of connecting part specially.

Hang surely the unit body onto the upper notches of the

mounting plate. Move the body from side to side to verify

its secure fixing.

In order to fix the body onto the mounting plate,hold up

the body aslant from the underside and then put it down

perpendicularly.

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.

Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape

1. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar

qualified person. The type of connecting wire is H05/07RN-F or 245IEC57(YZW).

2. If the fuse 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.

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.

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.

To bend a pipe, give the roundness as large as possible not to crush the pipe

,and the bending radius

Connecting the pipe of gas side first makes working easier.

Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into

terminal block, then tighten the screws.

If wiring is not correct, proper operation can not be carried out and controller may be damaged.

If the drain-elbow is used, please attach it as

figure. (Note: Only for heat pump unit.)

Drawing for the installation of indoor and outdoor units

Insert the cable according to terminal number in the same manner as the indoor unit.

Fix the cable with a clamp.

The longest connecting pipe is at most 15 meters,and the max vertical distance between the indoor

unit and the outdoor unit is 5 m.

5.Purging Method:

Push the air out of the indoor unit

and piping as followes:

(1) Remove the valve cap on 2-way

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 90ousing

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.

(5) Tighten the caps on the valves

with specified torque.
