INDOOR UNIT INSTALLATION
INDOOR UNIT INSTALLATION
Connect the indoor unit first, then the outdoor unit.
Do not allow the piping to let out from the back of the indoor unit.
CAUTION
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 overflow inside the unit.
Never intercross nor intertwist the power wire with any other wiring.
Fig.6
4.Drain piping
1. Connect the drain hose as described
in Fig.6. The drain hose should be
inclined downward.
2. When drain hose requires extension,
obtain an extension hose commercially
available. Be sure to thermally insulate
the indoor section of the extension
hose. Do not let the drain hose slack.
3. Remove the air filter and pour some
water into the drain pan to check
the water flows smoothly.

The wire size of power supply cord
and interconnected wire and the
current of the fuse or switch are
determined by the maximum current
indicated on the nameplate which
located on the side panel of the unit.
Please refer to the nameplate before
selecting the wire size, fuse or switch.
The controller of the air conditioner
designed with a fuse protection
function under abnormal conditions,
the specifications of the fuse have
printed on the circuit board, such as:
T3.15A/250VAC, T5A/250VAC, etc.
NOTE:
Electric safety regulations for the initial Installation
1. If there is serious safety problem about the power supply, the technicians should refuse to
install the air conditioner and explain to the client until the problem is solved.
2. Power voltage should be in the range of 90%~110%of rated voltage.
3. The surge protector and main power switch with a 1.5 times capacity of Max. Current of the unit
should be installed in power circuit. Ensure the air conditioner is grounded well.
4. The appliance shall be installed in accordance with national wiring regulations.
Do not operate
your air conditioner in a wet room such as a bathroom or laundry room.
5. An all-pole disconnection device which has at least 3mm clearances in all poles, and have a
leakage current that may exceed 10mA, the residual current device(RCD) having a rated
residual operating current not exceeding 30mA, and disconnection must be incorporated in the
fixed wiring in accordance with the wiring rules.
6. For the unit adopts auxiliary electric heater, keep at least 1 meter away from the nearest
combustible materials.
7. According to the attached Electrical Connection Diagram located on the panel of the indoor &
outdoor unit to connect the wire.
8. All wiring must comply with local and national electrical codes and be installed by qualified and
skilled electricians.
9. Every wire must be connected firmly. No wire should be allowed to touch refrigerant tubing,
the compressor, or any moving parts.
10. Loose wiring may cause the terminal to overheat or result in unit malfunction. A fire hazard
may also exist. Therefore, be sure all wiring is tightly connected.
9. An individual branch circuit and single receptacle used only for this air conditioner must be
available. See the following table for suggested wire sizes and fuse specifications:
Electrical work
5. Connect the cable to the indoor unit
,
Before performing any electrical work, turn off the main power to the system.
1. The indoor power cord type is H05VV-F or H05V2V2-F, the outdoor power cord and
interconnected cord type is H07RN-F.
2. Lift the indoor unit panel up, use an sharp end tool like a screw driver to pry the wire cover.
3. Remove the cable clamp. Match wire colours with terminal numbers on indoor and outdoor
unit s terminal blocks and firmly screw wires to the corresponding terminals.
4. Connect the end of the connection cable fully inserting into the terminal block.
5. Fasten the connection cable with a cable clamp.
NOTE:
The wiring connection is differ from appliance to appliance.(see page 12)
