Consult local building codes and National Electrical Code
(NEC, U.S.A.) for special installation requirements.

Max. cable length. Total voltage drop should not exceed 1V.
Therefore max. length:

For #18 AWG 24.3 Feet (7.4 m)
For #16 AWG 37.7 Feet (11.5 m)
For #14 AWG 50.0 Feet (18 m)

•

Use only type "G" or "C" fuses. Use single length power
cable without extension. Allow sufficient space for airflow
clearance on condensing 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
Minimum length of 10 ft. apart.
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.

CAUTION

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. W ear safety glasses and work gloves.
Keep quenching cloth and fire extinguisher nearby when brazing.
Use care in handling, rigging, and setting bulky equipment.

WARNING

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.

GENERAL

These instructions cover the installation, start-up and servic­ing of DFC2A/DFC2H outdoor and DFF2A/DFF2H indoor units cool­ing only and heat pump duct free systems. See Table 1 for parts
included. See Tables 2 and 3 for Physical Data.

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 refriger-ant slugging and could possibly damage the com­pressor at start-up.

System Requirements

IMPORTANT: The Indoor units & the inter units cable

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 unit's 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 2.5-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" 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.

WIRE THE INDOOR UNIT

1. Strip the cables back 1/4 inch.

2. Remove the unit's front panel by lifting the lower part and
pulling it gently outward and upward. See Fig. 6.

3. Remove the two screws from the control box cover and take
off the cover. See Fig. 7. Save the screws to reassemble.

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.

•

Pull downwards and outwardston the bottom of the grille
and gently raise the frame of the top of the unit.

•

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.

•

Route the interconnecting unit's electric cable and the
outdoor sensor cable towards the lower right hand corner of
the indoor unit.

•

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.

•

Secure the control cables to the strain relief.

•

For heat pump systems only, connect the outdoor sensor
TH3 to its mating black terminal. See Fig. 9.

REASSEMBLE

1. Connect the display connector to the display panel printed
circuit board.

2. Put the control box cover and grille frame back on using the
appropriate screws (Steps 3 and 4 of Wire the Indoor Unit
section). Put the grille insert back on.

Fig. 6 — Remove Grille Insert

Fig. 7 — Remove Control Cover

CAUTION

Make sure that all wires and screws are firmly fastened. Loose
wires or connections can cause damage and present a fire
hazard.

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 unit's 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).
