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.
GENERAL
System Requirements
Consult local building codes and National Electrical
Code (NEC, U.S.A.) for special installation requirements.
Use only type G or C fuses.
Use single length power cable without extension.
Allow sufficient space for airflow clearance on condens-
ing units for wiring, refrigerant piping, and servicing
unit. See Fig. 1 and 2 for minimum required distances
between unit and walls or ceilings.
Indoor and outdoor units should be installed at a
Maximum line length of 50 ft, and
vertical separation of 30 ft.
Do not install indoor units near a direct source of heat
such as direct sunlight, steam or flame.
Before installing or servicing system, always turn off main
power to system and install lockout tag on disconnect.
There may be more than one disconnect switch. Electrical
shock can cause personal injury.
IMPORTANT: The Indoor unit & the inter units cable voltage
is 30 VDC
IMPORTANT: Each refrigerant line must be insulated
separately. See line sizing requirements in table 2.
Do not bury more than 36 in. of refrigerant pipe in the
ground. If any section of pipe is buried, there must be a
6 in. 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.

INSTALLATION
Plan the installation carefully to avoid component failures
and make installation easier.
Indoor Unit Installation
REFRIGERANT LINE ROUTING The refrigerant lines
may be routed in any of the four directions shown in Fig. 3.
INSTALL THE MOUNTING BRACKET
1. Carefully remove the mounting bracket, which is
connected to the back of the indoor units base with
screws.
2. Position the mounting bracket on the wall and level it
using a spirit level (see Fig. 2 for minimum required
clearance distances).
3. Mark the four drilling holes on the wall, as they appear in
Fig. 4.
4. Drill the holes, insert the wall plugs and use four long
screws to attach the mounting bracket to the wall.
5. Check that the bracket is leveled and securely fastened to
the wall.
DRILL A HOLE IN THE WALL FOR DRAINAGE AND
INTER-UNIT CONNECTIONS To make the connections
between the indoor and outdoor units, drill a 3-in. hole through
the wall for the refrigerant lines, drainage hose and control
cable passage as shown in Fig. 5.
1. Mark the center of the hole to be drilled according to the refrigerant line routing used and dimensions shown in Fig. 4.
2. Make sure to drill outwards and downwards, so that the
opening in the outside wall is at least
1
/2-in. lower than
the opening on the inside.
3. Make sure the drainage hose is at the bottom side of the
hole.
4 . If refrigerant line route no. 1, 2 or 4 are used, use a small
saw blade to carefully remove the corresponding plastic
covering on the side panel.
5. Run the outdoor sensor cable, electrical cable, refrigerant
lines, and drainage tube through the hole.
6. Fill the remaining wall hole gap with an appropriate
sealant material.

MAKE DRAINAGE CONNECTIONS
1. Connect the unattached end of the drainage tube to the
drainage hose outlet.
2. Seal the drainage connection to prevent leakage.
3. Make sure there are no kinks, U bends or flattened
sections in the tube.
4. Check that the drainage functions properly. Fill the pan
below the units coil with water and observe that it freely
drains out.
5. Make sure the drainage hose is at the bottom side of the
wall through-hole (see Fig. 5).
outdoor sensor cable towards the lower right hand corner
of the indoor unit.
WIRE THE INDOOR UNIT
2. Remove the unit's front panel by lifting the lower part
and pulling it gently outward and upward. See Fig. 6.
5. Pull downwards and outwardston the bottom of the grille
and gently raise the frame of
the top of the unit.
3. Remove the two screws from the control box cover
and take off the cover. See Fig.
7. Save the screws to reassemble.
6 . Once all covers are off, mount the unit onto the wall
mounting bracket. See Fig. 8.
NOTE: Leave covers off until after the Making Drainage
Connections section.
7 . Route the interconnecting units electric cable and the
Make sure that all wires and screws are firmly fastened.
Loose wires or connections can cause damage and present
a fire hazard.
1.Strip the cables back1/4 inch.
8. Make sure that the wires are connected in accordance
with the wiring diagram on the inside of the unit front
cover or within this instruction manual.
9. Secure the control cables to the strain relief.
10. For heat pump systems only, connect the outdoor sensor
TH3 to its mating black terminal. See Fig.
9.
NOTE: In general wiring the indoor unit does not require the
removal of the grille frame but in case of need do as follow:
4. Remove the two screws from the air discharge opening.
Save the screws to reassemble. See Fig. 7A.
1. Connect the display connector to the display panel
