Concealed Duct High-Static Pressure Type (D Type)

3-25. Required Minimum Space for Installation and Service

This air conditioner is usually installed above the ceiling

so that the indoor unit and ducts are not visible. Only the

air intake and air outlet ports are visible from below.

The minimum space for installation and service is shown

in Fig. 3-100.

It is recommended that space be provided (23-5/8"

23-5/8") for checking and servicing the electrical system.
