4.3. INSTALLATION DIMENSIONS
Be careful of the following issues for selecting position of outdoor unit.
• Install with sufficient space when taking into consideration such as conveyance routes, installation space,
walk space and maintenance.
• Observe the installation space specifications that are shown in the figures.
If installation is not performed according to the specifications, it could cause a short circuit and result in a
lack of performance.
As a result, outdoor unit might be stopped by high-pressure protection easily.
• During installation, take into account the installation space required for the refrigerant piping space.
Single unit installation
1 The installation space must be satisfied for each wall (front, rear, sides) are shown below (Fig. 4.3-1):
• There must be no obstructions on the blowing side of the fan.
If there are obstructions on the blowing side of the fan, a discharge duct must be used.
• The wall height on the front must be H1 (600 mm) or less.
• The wall height on the rear must be H2 (300 mm) or less.
• If the wall height on the front exceeds H1 = 600 mm, the distance h1 (the distance by which it exceeds H1) must be added to the
L1 (500 mm) service space.
• If the wall height on the front exceeds H2 = 300 mm, the distance h2 (the distance by which it exceeds H2) must be added to the
L2 (300 mm) service space.
• There is no limit to the wall height on the side.
• The sides of the unit and the walls must be separated by a distance of 10 mm or more.
If the distance from the sides of the unit to the walls is 150 mm or less, the 6 screws on the right side of the unit must be removed
before installation.
• If H1 < = 600 mm, then L1
• If H2 < = 300 mm, then L2
• If H1 > 600 mm, then L1
• If H2 > 300 mm, then L2

2 If unit needs to install at a high front and rear wall height because of a small installation space (Fig. 4.3-2):
• There must be no obstructions on the blowing side of the fan.
If there are obstructions on the blowing side of the fan, a discharge duct must be used.
• If space cannot be secured on the front and rear (L1 < 500 mm + h1, L2 < 300 mm + h2), do not install walls on the sides.
If there is a high wall front or rear side, at least 2 sides must be opened.
• The wall height on the front and rear must be 1,500 mm or less.
• A service space must be secured of L1
