Special Installation (Embedding in the wall)
(2) Embedding in walls with no space provided behind the unit
X (Front of the unit)
A
Y (Rear of the unit)
We do not recommend installation in narrow enclosed areas.
• If the unit must be installed in a narrow area, the following conditions must be met:
A mm
B mm
• Ensure proper ventilation in space Y indicated in the illustration with an air conditioner or fan, to prevent
heated air from stagnating. Observe the temperature restrictions specified below. If heated air stagnates inside
the area, temperatures at points may rise high enough to produce breakdowns or fire. Confirm that the inner walls
are capable of resisting heat and fire (their composition should be fireproof), allowing for worst-case instances. Air
should flow in the direction indicated by the arrow (from points without fans to points with fans).
* Operating Temperature Restrictions
A: No restriction; B: 100 to 300 mm
A: No restriction; B: more than 300 mm
* Operating Temperature Restrictions for Upside-Down Installations
* Upside-down mounting is unavailable when the unit is embedded/installed into a wall.
