3. PIPING CONNECTIONS
TO OUTDOOR UNIT
• Remove service valve cover to access the
service valves and refrigerant ports.
• Carefully bend and adjust length of refrigerant
pipes to meet outdoor unit service valves
connection with proper tools to avoid kinks.
• Apply a small amount of refrigerant oil to the
flare connection on the refrigerant pipe.
• Properly align piping and tighten flare nut using
a standard wrench and a torque wrench as
shown in the indoor piping section.
• Carefully tighten flare nuts to correct torque
level referring to the following Torque Table:
WARNING
Florida wind load requirements state that outdoor unit
must be anchored to concrete pad using four 3/8-in
diameter power wedge bolt plus(or equivalent) with
1-in diameter fender washers. Anchor bolts must
be embedded into 3000 PSI minimum concrete at
a distance of 4 1/2- in from any concrete edge. The
concrete thickness must exceed 1.5 times the anchor
depth. Always check local ordinances for additional or
updated requirements

OUTDOOR UNIT INSTALLATION
1. INSTALL CONDENSATE DRAIN
FOR OUTDOOR UNIT
The condensate drains from the outdoor unit
when the unit operates in heating mode. In order
not to disturb your neighbor and protect the
environment, install a drain port and a drain hose
to direct the condensate water. Just install the
drain port and rubber washer to the chassis of the
outdoor unit, then connect a drain hose to the port
as the right figure demonstrates.

2. INSTALL GROUND PAD
OR WALL HANGERS
Determine proper location for outdoor unit.
Follow all instructions provided by
manufacturer for installing wall hangers
rubber pad.
Verify the wall hangers or rubber pad can
safely support the weight of the outdoor unit.
Verify the wall hangers or rubber pad is level
and meets all outdoor dimensional clearance.
Fix with bolts and nuts tightly on a flat and
strong floor.
If installed on the wall or roof, make sure to fix the
supporter well to prevent it from shaking due to
serious vibration or strong wind.

POWER AND WIRING
CONNECTING OF THE CABLE
Outdoor Unit
Connect the communication cable to the indoor
unit by connecting the wires to the terminals on
the control board individually in accordance with
the outdoor unit connection.
Indoor Unit
Remove the cable cross board from the
unit by loosening the screw. Connect the
wires to the terminals on the control board
individually as follows.
Secure the communication cable onto the
condenser with cable clamp.
Reinstall the cable cross board to the
original position with the screw.
Use a recognized circuit breaker
between the power source and the unit.
A disconnecting device to adequately
disconnect all supply lines must be fitted.
The figures in this manual are based on the
external view of a standard model. Consequently,
the shape may differ from that of the air
conditioner you have selected.
CAUTION:
Never fail to have an individual power circuit specifically for the air conditioner. As for the method of
wiring, refer to the circuit diagram posted on the inside of the access door .
Confirm that the cable thickness is as specified in the power source specification.
Check the wires and make sure that they are all tightly fastened after cable connection.
Be sure to install an earth leakage circuit breaker in wet or moist areas.
