Capacity is based on standard length and maximum allowance

length is on the basis of reliability.

Oil trap should be installed every 5~7 metres.

When the connecting pipe is longer than 5 metres, additional

refrigerant should be added into the unit according to the

above table through the service port on the “LO” valve on

outdoor unit.

Indoor unit installation

Fig.4

Note:

1. Fit the Installation Plate

1). Fit the installation plate horizontally

on structural parts of the wall with

spaces around the installation plate.

2). If the wall is made of brick, concrete or

the like, drill eight (8) 5mm diameter holes

in the wall. Insert Clip anchor for appropriate

mounting screws.

3). Fit the installation plate on the wall with eight

(8) type “A” screws.

Correct orientation

of Installation Plate

Fit the Installation Plate and drill holes in the wall according to the wall structure and corresponding

mounting points on the installation plate.

(Dimensions are in “mm” unless otherwise stated)

2. Drill a hole in the wall

1. Determine hole positions according to

the diagram detailed in Fig.5. Drill

one (1) hole ( 65mm <998*322 or

95mm >1250*325) slanting slightly

to outdoor side.

2. Always use wall hole conduit when

drilling metal grid, metal plate or the like.

1. For the left-hand and right-hand piping, remove the pipe cover from the side panel.

2. For the rear-right-hand and rear-left-hand piping, install the piping as shown. Bend the

connecting pipe to be laid at a height of 43mm or less from the wall.

3. Fix the end of the connecting pipe. (Refer to Tightening Connection in REFRIGERANT

PIPING CONNECTION)

1. Pass the piping through the hole in the wall.

2. Put the upper claw at the back of the indoor unit on

the upper hook of the installation plate, move the

indoor unit from side to side to see that it is securely

hooked.

3. Piping can easily be made by lifting the indoor unit

with a cushioning material between the indoor unit

and the wall. Remove cushioning material after finish

piping.

4. Push the lower part of the indoor unit up on the wall,

Then move the indoor unit from side to side, up and

down to check if it is hooked securely.

3. Connecting Pipe and Drainage Installation

1. Run the drain hose sloping downward. Do not install the drain hose as illustrated below.

2. When connecting an extension drain hose, insulate the connecting part of the extension

drain hose with a shield pipe, do not let the drain hose become slack.

5. Piping and wrapping

Bundle the tubing, connecting cable, and

drain hose with tape securely and

evenly as shown in Fig.11.

Because the condensed water from rear

of the indoor unit is gathered in ponding

box and is piped out of room. Do not put

anything else in this box.

Drain hose

Connect the indoor unit first, then the outdoor unit.

Do not allow the piping to be exposed out from the back of the indoor unit.

Be careful not to let the drain hose become slack.

Heat insulate the connecting piping.

Be sure that the drain hose is located at the lowest side of the bundle. Locating

at the upper side can cause drain pan to overflow inside the unit.

Never cross connect or inter wind the power wire with any other wiring.

Run the drain hose sloped downward to drain out the condensed water smoothly.

CAUTION

Install the outdoor unit on a rigid base to prevent noise and vibration.

Select the air outlet direction so that discharged air is not blocked.

In the case where the installation location is exposed to strong winds,

make sure the fan operates properly by putting the unit lengthwise along the wall

or by using a shield to minimise wind exposure.

Especially in windy areas, install the unit to minimise exposure to wind.

For suspended installations, the installation bracket should follow with technique

requirement in the installation bracket diagram. The installation wall should be solid

brick, concrete or of same construction,

or reinforced to minimise movement or vibration.

The connection between the wall bracket and the

air conditioner should be firm, stable and reliable.

Ensure there lare no obstacles which block

flow air.

Outdoor unit installation precautions

INSTALLATION

REFRIGERANT PIPE CONNECTION

Securing of outdoor unit

Anchor the outdoor unit with

a bolt and nut 10 or 8 tightly

and horizontally on a concrete

or rigid mount.

If a drain elbow is used, the unit should be placed

on a stand which is taller than 3cm.

If the unit is used in an area where temperature

O

falls below 0 C for 2 or 3 days in succession, it

is recommended not to use a drain elbow, as the

drain water may freeze and the fan will not rotate.

Fit the seal into the drain elbow, then insert

the drain joint into the base pan hole of the

outdoor unit, rotate 90 to secure. Connect

the drain joint with an extension drain hose

(Locally purchased), in instances where you

need to drain condensed water away from the unit.

Roughness

Burr

Main cause for refrigerant leakage

is due to defects in the flaring work.

Carry out correct flaring work

using the following procedure:

A: Cut the pipes and the cable.

1. Use the piping kit accessory (if applicable) or pipes

purchased locally.

2. Measure the distance between the indoor and the outdoor unit.

3. Cut the pipes a little longer than the measured distance.

4. Cut the cable 1.5m longer than the pipe length.

B: Burr removal

1. Completely remove all burrs from the cut

cross section of pipe/tube.

2. Face the end of the copper pipe/tube in a

downward direction as you remove burrs in

order to avoid burrs dropping into the tubing.

having completed burr removal (Note: It is not

possible to put them on after flaring work).

D: Flaring work

Firmly hold copper pipe in a die according

to the dimension shown in the table below.

Carry out flaring work using flaring tool as

shown below.

Caution

Align the center of the pipes.

Sufficiently tighten the flare

nut with fingers, and then tighten

it with a spanner and torque wrench

as shown.

Excessive torque can break nut

depending on installation conditions.
