2.9 Wiring connection of indoor

unit

Fig.3

Fig.4

CAUTION!

Check the wiring to make sure that

there is no short circuit. Incorrect

wiring can cause malfunction.

Ensure the colour of wires of outdoor

unit and the terminal Nos. are the

same to the indoor’s respectively.

When installing the indoor unit to a

Multioutdoor unit the “W” terminal

donot need to be connected.

1. Open the front panel.

2. Remove the wiring cover.

3. Fix the mains cord to the terminal

board (as shown).

4. Guide the mains cord through the

hole at the back of the indoor unit.

5. Install the cord anchorage and wiring

cover.

6. Close the front panel.

NOTE:

• The electrical wiring between the indoor

unit and the outdoor unit must be

connected by a qualied electrician.

• Tighten the terminal screws tightly.

• After tightening the screws, pull the

wire slightly to conrm whether it’s rm

or not.

• Make sure that the electrical

connections are properly grounded to

prevent electric shock.

2.10 Connective pipe installation

1. For the left-hand and right-hand

piping, remove the pipe cover from

the side panel.

2. For the right back and left back

piping, install the piping as shown.

NOTE:

This unit have a both sides drainage

structure, it can be choosen for right,

left or both sides drainage connection. If

choosing both sides drainage connection,

another proper drain hose is needed as

there is only one drain hose offered by

factory. If choosing one side drainage

connection, make sure the drain hole on

the other side is well plugged. For 9k/12k

models, if choosing right side drainage

connection, please choosing right-hand

or right-back piping. The connection of

the drain hose is supposed to be done by

qualied installer in case of water leakage.

3. Bundle the tubing, connecting cable,

and drain hose with tape securely,

evenly as shown in Figure below.

CAUTION!

Connect the indoor unit rst, then

the outdoor unit.

Do not allow the piping to let out

from the back of the indoor unit.

Be careful not to let the drain hose

slack.

Heat insulation should be done to

the extension drain hose of indoor

unit.

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 overow

inside the unit.

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

the box.

3. CASSETTE TYPE INSTALLATION

2.11 Indoor unit installation

1. Pass the piping through the hole in

the wall.

2. Hook the indoor unit onto the upper

portion of installation plate(Engage

the indoor unit with the upper edge

of the installation plate). Ensure the

hooks are properly seated on the

installation plate by moving it in left

and right.

3. Piping can easily be made by lifting

the indoor unit with a cushioning

material between the indoor unit and

the wall. Get it out after nish piping.

4. Press the lower left and right side of

the unit against the installation plate

until hooks engages with the their

slots.

when necessary.

2. Please select the position of

installation hooks according to the

hook holes on the installation board.

• Drill four holes of ø12mm, 50~55mm

deep at the selected positions on the

ceiling. Then embed the expansible

hooks (ttings).

• Face the concave side of the installation

hooks toward the expansible hooks.

Determine the length of the installation

hooks from the height of ceiling, then

cut off the unnecessary part.

• If the ceiling is extremely high, please

determine the length of the installation

hook according to facts.

reinforcing rod (ø12) to weld together

The length could be calculated from

Fig.15: Length=210+L(in general, L is half

of the whole length of the installation hook)

3. Please adjust the hexangular nuts on

the four installation hooks evenly, to

ensure the balance of the body.

• Use the lever indicator check the lever

from four sides of the main body. (Refer

to Fig.16)

• If the drainpipe is awry, leakage will

be caused by the malfunction of the

waterlevel switch.

• Adjust the position to ensure the gaps

between the body and the four sides of

ceiling are even.

• The body’s lower part should sink into

the ceiling for 10~12mm.

• Locate the air conditioner rmly by

wrenching the nuts after having

adjusted the body’s position well.

hook can be embedded in advance

(refer to the existing ceiling installation

mentioned above). But it should be

strong enough to bear the indoor unit

and will not become loose because of

concrete shrinking.

2. After installing the body, please fasten

the installation paper board onto the

air conditioner with bolts (M5×16)

to determine in advance the sizes

and positions of the hole opening

on ceiling. Please rst guarantee the

atness and horizontal of ceiling when

installing it. Refer to the existing

ceiling installation mentioned above

for others.

3. Refer to the existing ceiling installation

mentioned above for installation.

4. Remove the installation paper board.

Install The Panel

CAUTION!

Never put the panel face down on

oor or against the wall, or on bulgy

objects.

Never crash or strike it.

Remove the inlet grid.

1. Slide two grid switches toward the

middle at the same time, and then

pull them up.

3.8 Drainage pipe installation

1. Installation principle

• Ensure at least 1/100 slope of the

drainage pipe.

• Adopt suitable pipe diameter

• Adopt nearby condensate water

discharge.

• Before installing condensate water

pipeline, determine its route and

elevation to avoid intersection with

other pipelines and ensure slope is

straight.

• In general, the supporter gap of the

drainage pipe horizontal pipe and

vertical pipe is respectively 1m~1.5m

and 1.5m~2.0m.

Fig.25

2. Drainage pipe selection

• The drainage pipe diameter shall not

small than the drain hose of indoor unit.

• According to the water owrate and

drainage pipe slope to choose the

suitable pipe, the water owrate is

decided by the capacity of indoor unit.

Capacity(Btu/h) Water owrate(l/h)

9000 2

12000 2.4

18000 4

• According to the above table to

calculate the total water owrate for the

conuence pipe selection.

• The horizontal pipe layout should avoid

converse ow or bad ow(Fig 26):

3. Water storage pipe setting

• If the indoor unit has high extra static

pressure and without water pump to

elevate the condensate water, such

as high extra static pressure duct unit,

the water storage pipe should be set

to avoid converse ow or blow water

phenomena (Fig 27).

4. Lifting pipe setting of indoor unit with

water pump

• The length of lifting pipe should not

exceed the pump head of indoor unit

water pump.

• Pump head of big four way cassette:

750mm.

• Pump head of compact four way

cassette: 500mm(9k, 12k, 18k units).

• The drainage pipe should be set down

inclined after the lifting pipe immediately

to avoid wrong operation of water level

swithch.

• Refer the following picture for

installation reference.

5. Blowhole setting

• For the concentrated drainage pipe

system, there should design a blowhole

at the highest point of main pipe to

ensure the condensate water discharge

smoothly.

The air outlet shall face down to prevent

dirt entering pipe.

Each indoor system should be installed.

The installation should be considering

the convenience for future cleaning.

• Refer the following picture for

installation reference (Fig 29).
