SAFETY CONSIDERATIONS
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.
SYSTEM REQUIREMENTS
Allow sufficient space for airflow and servicing unit. See Fig. 1
for minimum required distances between unit and walls or ceilings.
Recommended Connection Method for Power and Communication Wiring ITo minimize communication wiring interference>

The main power is supplied to the outdoor unit. The field supplied
connecting cable from the outdoor unit to 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.
Consult your local building codes and the NEC (National
Electrical Code) or CEC (Canadian Electrical Code) for special
requirements.
All wires must be sized per NEC or CEC and local codes. Use
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 caution note, only copper conductors with a minimum 300 volt
rating and 2/64-inch thick insulation must be used.
Communication Wiring:
A separate shielded copper conductor only, with a minimum 300
volt rating and 2/64-inch thick insulation, must be used as the
communication wire from the outdoor unit to the indoor unit.
To minimize voltage drop of the control wire, use the following
wire size and maximum lengths shown in the chart below:

The drain pipe of indoor unit must be heat insulated, or it will
condense dew, as well as the connections of the indoor unit.
Hard PVC binder must be used for pipe connection, and make
sure there is no leakage.
7.2 Additional Refrigerant Charge
With the connection part to the indoor unit, be sure not to
impose pressure on the side of indoor unit pipes.
CAUTION
Refrigerant cannot be charged until field wiring has been
completed.
When the declivity of the drain pipe downwards is over 1/100,
there should not be any winding.
Refrigerant may only be charged after performing the leak
test and the vacuum pumping.
The total length of the drain pipe when pulled out traversely
shall not exceed 20m, when the pipe is over long, a prop stand
must be installed to prevent winding.
When charging a system, care shall be taken that the
maximum permissible charge is not exceeded, in view of the
danger of liquid hammer.
Refer to the figures on the right for the installation of the pipes.
4.9ft/1.5m~ 6.6ft/2m
Charging with an unsuitable substance may cause explosions
and accidents, so always ensure that the appropriate
refrigerant is charged.

The outdoor unit is factory charged with refrigerant. Some
systems require additional charging of refrigerant depending
on pipe lengths. The additional refrigerant to be charged can
be calculated from the following formule:
Put as deep as possible
(about 3.9in/10cm)
The standard pipe length will vary according to the requirements of
your area. For example, in North America area, the standard pipe
length is 25ft(7.5m). While in the other areas, the standard pipe
length is 16ft(5m).
