NOTE: Read the instruction manual before starting the installation.
SAFETY CONSIDERATIONS
Installing, starting up, and servicing air−conditioning equipment
can be hazardous due to system pressures, electrical components,
and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should
install,start−up, and service this equipment.
Untrained personnel can perform basic maintenance functions such
as cleaning coils. All other operations should be performed by
trained service personnel.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
Follow all safety codes. Wear safety glasses and work gloves. Keep
quenching cloth and fire extinguisher nearby when brazing. Use
care in handling, rigging, and setting bulky equipment.
Read these instructions thoroughly and follow all warnings or
cautions included in literature and attached to the unit. Consult
local building codes and National Electrical Code (NEC) for
specialrequirements. Recognize safety information.
This is the safety−alert symbol !
! . When you see this symbol on
the unit and in instructions or manuals, be alert to the potential for
personal injury. Understand these signal words: DANGER,
WARNING, and CAUTION. These words are used with the
safety−alert symbol. DANGER identifies the most serious hazards
which will result in severe personal injury or death. WARNING
signifies hazards which could result in personal injury or death.
CAUTION is used to identify unsafe practices which may result in
minor personal injury or product and property damage. NOTE is
used to highlight suggestions which will result in enhanced
installation,reliability, or operation.
!WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing, modifying, or servicing system, main
electrical disconnect switch must be in the OFF
position. There may be more than 1 disconnect switch.
Lock out and tag switch with a suitable warning label.
!WARNING
ELECTRICAL DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Do not install the wired controller in an area subjected
to excessive steam, oil or sulfide gas. Doing so may
cause the controller to to deform and/or fail.

INSTALLATION AND DISASSEMBLY
CONNECTION TO THE HIGH WALL INDOOR
UNIT:
Consult the installation instructions of each indoor unit for proper
installation. Connect the 4−core wire shipped with the wired
controllerto the wire with a molex connector shipped with the unit
and already connected to the PCB Board to COM−INNER1.
WIRED REMOTE CONTROLLER SIGNAL LINE
CONNECTION
SOpen the indoor unit’s electrical control box cover.
SRun the signal line of the wired remote controller through
the rubber ring.
SConnect the wired remote controller’s signal line to the
indoor unit PCB’s 4−pin socket.
STighten the signal wire with ties.
SThe communication distance between the main board and
the wired remote controller can extend up to 65.62 feet ( 20
meters)(the standard distance is 26 feet (8 meters)).

Figure 18 displays the wired remote controller installation steps.
NOTE: There are several issues that require the installer’s attention.
1. Prior to the installation, cut off the power supply to the wire buried in the installation hole.
2. Remove the four−core twisted pair line from the installation holes and run them through the rectangular hole behind the wired remote
controller plate.
3. Secure the wired remote controller plate to the wall, over the installation hole, and then secure the plate with the screws (M4X25).
4. Insert the four−core twisted pair line into the wired remote controller slot and then buckle the front panel and the plate of the wired
remote controller together.
5. Secure the front panel and the wired remote controller plate tightly with the screws (ST2.9X6).

Fig. 18 - Installation Steps
Please pay special attention to the following directions
during the connection to avoid air conditioning malfunction
due to electromagnetic interference.
CAUTION
!
1. Separate the wired remote controller signal and
communication lines from the power cord and connection
lines between the indoor and outdoor unit, with a
minimum interval of 7.8 in (20cm), otherwise the unit’s
communication will probably malfunction.
2. If the air conditioning unit is installed in close proximity to
an electromagnetic interference, the signal and the wired
remote controller communication lines must be shielded by
twisted pair lines.
