Installation Of The Outdoor Unit
The outdoor unit must be firmly fixed to avoid falling in strong wind.
Install on the cement base the drawing below.
If it will be installed at seaside or at a place high above the ground and with strong wind, the AC should be
installed against the wall to ensure the normal operation of the fan and the blocking plate should be used.
If it will be installed in lift type, the structure of the monuting surface should be made of solid stick,cement
or materials with equivalent strength,and be of enough bearing capacity. Otherwise, measures such as
reinforcement, support or vibration damping should be adopted.

THE FORM OF PIPE
Maximum Piping Length
Note: Where the dierence in elevation between the indoor
unit and the outdoor unit is greater than 5 meters, install
an oil trap every 5 meters.
The suction line must have a 2% gradient up to the
compressor on horizontal sections.
Where piping lengths are unusually long and include a
large number of oil traps, it may be necessary to adjust
to compressor charge.
Refrigerant charge to be added per extra meter
of piping length when more than 3.6 meters.

The form of pipe
Wrap up all pipe, drain and connection wire from top
to below.
Cover the connection parts with insulation material and x
them with two plstic rings.
Wrap up the pipe with tape alongside the wall and x
them to the wall with clips. These steps are usually adopted
when outdoor unit is installed below the indoor unit.
In case that you want to have additional drain pipe, the end
of pipe should be within certain distance towards the surface
( it mustnt be in the water. Fix it onto the wall so it won’t be
swayed by the wind )
Wrap the pipes and connection wire rmly from below to top.
Wrap up the pipe that are rounded up by the wall coners in the
way shown in the picture so that it can prevent water entering
the room.
Use clips or other xture to fasten the pipes to the walls.
