Decide the installation position using mark on the installation 
plate indicating the indoor unit size as reference.

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 be-
tween the wall and the piping or wrap 
7 to 8 turns of insulation vinyl tape 
around the piping.

Lock the catch.

  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.

3.  INSTALLATION DIAGRAM & ACCESSORIES

FLARED CONNECTIONS

  This unit has fl ared connections on both indoor and outdoor sides.

  Remove the outdoor units valve cover, then connect the pipe.

  Refrigerant pipes are used to connect the indoor and outdoor units.

  Be careful not to crush or bend the pipe in pipe bending.

Limits

MS(H)-GD80

Pipe length

30 m max.

Height difference

15 m max.

No. of bends

10 max.

  Refrigerant adjustment ... If pipe length exceeds 7 m, additional refrigerant 

 

(R-410A) charge is required.

 

(The outdoor unit is charged with refrigerant for pipe length up to 7 m.)

Pipe length

Up to 7 m

No additional charge is required.

Exceeding 7 m

Additional charge is required.
(Refer to the table below.)

Refrigerant to 
be added

MS-GD80

55 g/m × (refrigerant piping length (m) -7)

MSH-GD80

55 g/m × (refrigerant piping length (m) -7)

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.
