Note:
When operating the air conditioner in low outside temperature,
be sure to follow the instructions described below.
•
Never install the outdoor unit in a place where its air inlet/outlet
side may be exposed directly to wind.
•
To prevent exposure to wind, install the outdoor unit with its
air inlet side facing the wall.
•
To prevent exposure to wind, it is recommended to install a
baffl e board on the air outlet side of the outdoor unit.

PIPING PREPARATION
1 Specifi cations
Use the refrigerant pipes that meet the following specifi cations.
Pipe
MS-GA60
MSH-GA60
For liquid
MS-GA80
MSH-GA71/80
For gas
• Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm (for
ø6.35, 9.52) or 1.0 mm (for ø15.88). Never use any pipe with a thickness less than
0.8 mm (for ø6.35, 9.52) or 1.0 mm (for ø15.88), as the pressure resistance is
insuffi cient.
2 Ensure that the 2 refrigerant pipes are insulated to prevent condensation.
3 Refrigerant pipe bending radius must be 100 mm or more.
Be sure to use the insulation of specifi ed thickness. Excessive thickness may cause
incorrect installation of the indoor unit and lack of thickness may cause dew drippage.

When the piping is to be attached to
a wall containing metals (tin plated)
or metal netting, use a chemically

treated wooden piece 20 mm or
thicker between the wall and the piping
or wrap 7 to 8 turns of insulation vinyl
I
tape around the piping.
Units should be installed by licensed contractor according
to local code requirement.
