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.

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.

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.

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).
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).
