b. Using wire strippers, strip the rubber jacket
from both ends of the signal cable to reveal
approximately 15cm (5.9”) of wire.
c.
Strip the insulation from the ends.
d. Using a wire crimper, crimp u-lugs on the
ends.
NOTE: When connecting the wires, strictly
follow the wiring diagram found inside the
electrical box cover.
2. Remove the electric cover of the outdoor unit.
If there is no cover on the outdoor unit, take
off the bolts from the maintenance board
and remove the protection board.

3. Connect the u-lugs to the terminals
Match the wire colors/labels with the labels
on the terminal block. Firmly screw the u-lug
of each wire to its corresponding terminal.
4. Clamp down the cable with the cable clamp.
5. Insulate unused wires with electrical tape.
Keep them away from any electrical or metal
parts.
6. Reinstall the cover of the electric control box.
Indoor Unit Wiring
1. Prepare the cable for connection
a. Using wire strippers, strip the rubber jacket
from both ends of the signal cable to reveal
about 15cm (5.9”) of the wire.
b. Strip the insulation from the ends of the
wires.
c. Using a wire crimper, crimp the u-lugs to
the ends of the wires.
2. Open the front panel of the indoor unit. Using
a screwdriver,remove the cover of the electric
control box on your indoor unit.
3. Thread the power cable and the signal cable
through the wire outlet.
4. Connect the u-lugs to the terminals.
Match the wire colors/labels with the labels on
the terminal block. Firmly screw the u-lug of
each wire to its corresponding terminal. Refer
to the Serial Number and Wiring Diagram
located on the cover of the electric control box.

CAUTION
• While connecting the wires, please strictly
follow the wiring diagram.
• The refrigerant circuit can become very
hot. Keep the interconnection cable away
from the copper tube.
5. Clamp down the cable with the cable clamp.
The cable must not be loose or pull on the
u-lugs.
6. Reattach the electric box cover.

- Caution 15
- Drainpipe installation 15
- All field piping must be completed by a licensed technician and must comply with the local and national regulations when the air conditioner is installed in a small room measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage if the refrigerant leaks and its concentration exceeds its proper limit hazards due to lack of oxygen may result when installing the refrigeration system ensure that air dust moisture or foreign substances do not enter the refrigerant circuit contamination in the system may cause poor operating capacity high pressure in the refrigeration cycle explosion or injury ventilate the area immediately if there is refrigerant leakage during the installation leaked refrigerant gas is both toxic and ammable ensure there is no refrigerant leakage after completing the installation work 17
- Ensure that the length of the refrigerant pipe the number of bends and the drop height between the indoor and outdoor units meets the requirements shown in table 7 17
- Notes on pipe length and elevation 17

- Refrigerant piping connection 17
- Refrigerant piping with twin indoor units when installing multiple indoor units with a single outdoor unit ensure that the length of the refrigerant pipe and the drop height between the indoor and outdoor units meet the requirements illustrated in the following diagram 17

- Charging with unsuitable substances may cause explosions or accidents ensure that the appropriate refrigerant is used refrigerant containers must be opened slowly always use protective gear when charging the system 25
- Do not exceed the maximum allowable quantity of refrigerant or overcharge the system doing so can damage the unit or impact it s functioning 25
- Do not mix refrigerants types 25
- Liquid side diameter 25
- Note on adding refrigerant 25
- Refrigerant charging must be performed after wiring vacuuming and the leak testing 25
- Some systems require additional charging depending on pipe lengths the standard pipe length varies according to local regulations for example in north america the standard pipe length is 7 m 25 in other areas the standard pipe length is 5m 16 the additional refrigerant to be charged can be calculated using the following formula 25
