4. INSTALLATION WORK
Make sure to obtain the customer's approval for selecting and installing the unit.
4.1. SELECTING AN INSTALLATION LOCATION
• Install the unit in a location that can withstand its weight, and where it will not topple or fall.
• Calculate the proper refrigerant concentration if you will be installing it in an enclosed location.
Total amount of replenished refrigerant in refrigerant facility (kg)
Capacity of smallest room where unit is installed (m
If the results of the calculation exceed the concentration limit, increase the room surface area or install a ventilation duct.
Select an installation location by observing the following precautions:
• Do not tilt the outdoor unit more than 3 degrees.
• Install the unit in a well-ventilated area away from rain or direct sunlight.
• If the unit must be installed in an area within easy reach of the general public, install as necessary a protec-
tive fence or the like to prevent their access.
• Install the unit in an area that would not inconvenience your neighbors, as they could be affected by the
airflow coming out from the outlet, noise, or vibration.
If it must be installed in proximity to your neighbors, be sure to obtain their approval.
• If the unit is installed in a cold region that is affected by snow accumulation, snow fall, or freezing, take
appropriate measures to protect it from those elements.
To ensure a stable operation, install inlet and outlet ducts.
• Install the unit in an area that would not cause problems even if the drain water is discharged from the unit.
Otherwise, provide drainage that would not affect people or objects.
• Install the unit in an area that has no heat sources, vapors, or the risk of the leakage of flammable gas in the
vicinity.
• Install the unit in an area that is away from the exhaust or vent ports that discharge vapor, soot, dust, or
debris.
• Install the indoor unit, outdoor unit, power supply cable, transmission cable and remote control cable at least
1 meter away from a television or radio.
The purpose of this is to prevent TV reception interference or radio noise. (Even if they are installed more
than 1 meter apart, you could still receive noise under some signal conditions.)
• Keep the length of the piping of the indoor and outdoor units within the allowable range.
• For maintenance purposes, do not bury the piping.
