• Create access door 1 and 2 (450x450mm each) as shown in Fig.2.
(Access door 2 is not required if enough space is available below the unit for a maintenance worker to work in.)
(1) When a space of 300mm or more is available below the unit between the unit and the ceiling. (Fig.1) and control box in one of the following ways. Secure enough access space to allow for the maintenance, inspection, and replacement of the motor, fan, drain pump, heat exchanger,
[Maintenance access space]
• Create access door 4 below the control box and the unit as shown in Fig.5.
or
•
Create access door 1 diagonally below the control box and access door
3 below the unit as shown in Fig.4.
(2) When a space of less than 300mm is available below the unit
between the unit and the ceiling.
(At least 20mm of space should be left below the unit as
shown in Fig.3.)
