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
special requirements.
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.
EXPLOSION HAZARD
Failure to follow this warning could
result in death, serious personal injury,
and/or property damage.
Never use air or gases containing
oxygen for leak testing or operating
refrigerant compressors. Pressurized
mixtures of air or gases containing
oxygen can lead to an explosion.
!WARNING
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe
in the ground. If any section of pipe is buried, there must
be a 6 in. (152 mm) vertical rise to the valve connections
on the outdoor units. If more than the recommended length
is buried, refrigerant may migrate to the cooler buried
section during extended periods of system shutdown. This
causes refrigerant slugging and could possibly damage the
compressor at start−up.

Note:
- If the outdoor unit is higher than the indoor unit, prevent rain from flowing into the indoor unit along the connection pipe by creating a downward arc
in the connection pipe before it enters the wall to the indoor unit. This ensures that rain drips from the connection pipe before entering the wall.
- Piping and the interconnecting wiring are field supplied.
- The parts list (Fig.1) is a sketch. Different models may be slightly different.

SYSTEM REQUIREMENTS
Allow sufficient space for airflow and servicing unit.
Piping
IMPORTANT: Both refrigerant lines must be insulated separately.
SMinimum refrigerant line length between the indoor and outdoor units is 10 ft. (3 m).
STable 2 lists the pipe sizes for the indoor unit. Refer to the outdoor unit installation instructions for other allowed piping lengths and
refrigerant information.

9K 12K
Gas Pipe in(mm) 3/8 (9.52) 1/2 (12.7)
Liquid Pipe in(mm) 1/4 (6.35) 1/4 (6.35)
All wires must be sized per NEC (National Electrical Code) or
CEC (Canadian Electrical Code) and local codes. Use the
Electrical Data table MCA (minimum circuit amps) and MOCP
(maximum over current protection) to correctly size the wires and
the disconnect fuse or breakers respectively.
Per the caution note, only stranded copper conductors with a 600
volt rating and a double insulated copper wire must be used.
IMPORTANT: The use of BX cable is not recommended.
Recommended Connection Method for Power and
Communication Wiring −Power and Communication Wiring:
The main power is supplied to the outdoor unit. The field
supplied 14/3 power/communication wiring from the outdoor unit
to the indoor unit consists of four (4) wires and provides the
power for the indoor unit. Two wires are high voltage AC power.
One wire is for communication wiring and the other is a ground
wire.
Recommended Connection Method for Power and
Communication Wiring (To minimize communication wiring
interference)
Power Wiring:
The main power is supplied to the outdoor unit. The field
supplied connecting cable from the outdoor unit to the indoor unit
consists of three (3) wires and provides the power for the indoor
unit. Two wires are high voltage AC power and one is a ground
wire.
Communication Wiring:
A separate stranded copper conductor only, with a 600 volt rating
and a double insulated copper wire must be used as the
communication wire from the outdoor unit to the indoor unit.
Please use a separate shielded 16GA stranded control wire.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
SWires should be sized based on NEC and local codes.
SUse copper conductors only with a 600 volt rating and
double insulated copper wire.

DRILL A HOLE IN WALL FOR
INTERCONNECTING PIPING, DRAIN AND WIRING
For maximum serviceability, it is recommended that you have
refrigerant line flare connections and the drain connections on the
outside of the wall that the fan coil can be mounted on.
1. Determine the pipe hole position.
2. Drill the pipe hole. The outside pipe hole is 1/2−in. (13 mm)
lower than the inside pipe hole, so it slants slightly down-
ward (see Fig. 6).

CONDENSATE DRAIN CONNECTION
The unit is supplied with a drain connection to connect the drain
piping. When installing condensate piping, follow these
recommendations:
SCondensate piping should slope downward in the direction
of the condensate flow, with a minimum gradient of 1 in.
per 100 inches.
SWhen multiple units are connected to a common
condensate drain, ensure the drain is large enough to
accommodate the volume of condensate from all units. It
is also recommended to place an air vent in the condensate
piping to prevent any air locks.
SCondensate piping must not be installed where it may be
exposed to freezing temperatures.

INSTALLATION
For setup instructions, refer to the Wired controller installation
manual.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Never use the system compressor as a vacuum pump.
CAUTION
!
Refrigerant tubes and indoor coil should be evacuated using the
recommended deep vacuum method of 500 microns. The alternate
triple evacuation method may be used if the procedure outlined
below is followed. Always break a vacuum with dry nitrogen.
Final Tubing Check
IMPORTANT: Ensure certain factory tubing on both the indoor
and outdoor unit has not shifted during shipment. Ensure the tubes
are not rubbing against each other or any sheet metal. Pay close
attention to feeder tubes, making sure wire ties on the feeder tubes
are secure and tight.
START−UP
Test Operation
Perform a test operation after completing a gas leak and electrical
safety check.
1. Press ON/OFF on the remote control to begin testing.
NOTE: A protection feature prevents air conditioner from being
activated for approximately 3 to 4 minutes.
2. Press MODE and select COOLING, HEATING, FAN
mode to check if all functions work correctly.
3. To run the test using the manual button in the indoor unit:
(1.) Open the indoor unit’s front panel;
