Preparing for installation
Complete the necessary preparation before you begin the installation:
1. Visit the installation site to select a suitable location for the outdoor unit and plan the
refrigerant piping system.
2. Inspect the outdoor unit.
3. Make sure that you are aware of the installation and operation limitations.
4. Familiarise yourself with the requirements for installing or servicing R-454B equipment and
make sure you have all necessary equipment.
Selecting a location for installation
About this task:
Before starting the installation, you must select a suitable location for the outdoor unit. Observe all
limitations and clearance requirements. You can install the outdoor unit on the ground, on a roof,
or on a wall.
Note: For more information about selecting a suitable location for the indoor unit, refer to the
Installation Manual for the indoor unit.
WARNING
The outdoor unit must not be installed in an area where mud or ice could cause personal injury.
NOTICE
For multiple unit installations, units must be spaced a minimum of 24 in. (61 cm) apart (coil face to coil
face).
Important: Avoid the following places for installation where damage to the outdoor unit may
occur:
• Where there is machine oil
• Coastal regions where the equipment is prone to atmospheric corrosion
• Near hot springs where the equipment is prone to sulfide gas corrosion
• In proximity to high-frequency or wireless equipment
Select a location for the outdoor unit that meets the following general requirements for installation:
• Is away from bedroom windows or other room windows where the sound of the unit operation
might be objectionable.
• Provides adequate structural support for the unit.
• Allows sufficient clearance for air entrance to the outdoor coil, air discharge, and service access.
• Isolate the unit from rain gutters to avoid any possible wash out of the foundation.
• Allows you to elevate the unit sufficiently to prevent any blockage of the air entrances by snow
in areas where snow may accumulate. Check the local weather bureau for the expected snow
accumulation in your area.
