Installation Location; Single Unit Installation - Mitsubishi Electric CITY MULTI PURY-HP-TNU-A Manuel D'installation

7. Installation location

Do not install the unit where combustible gas may leak.
- If combustible gas accumulates around the unit, fire or explosion may result.
・Provide sufficient space around the unit for effective operation, efficient air movement, and ease of access for maintenance.
・Note that refrigerant gas is heavier than air and will therefore tend to collect in low spots such as basements.
・When an indoor unit that draws in outside air exits near the outdoor unit, be careful not to affect the normal operation of the indoor unit.
・When the amount of drain water is excessive, drain water comes out of the outdoor unit along the panel during heating operation. Provide
sufficient space around the unit according to the instructions below.
