- If there are no walls on the front and rear sides, clearance for service access is required as follows:
* Front Side: Minimum 19-11/16 inches (500mm)
* Rear Side: Minimum 11-13/16 inches (300mm)
* Right and Left Sides: Minimum 3/8 inches (10mm)
(In an instance where the snow protection hood (optional part) or the air outlet
duct (field-supplied) is mounted to the unit, a minimum gap of 1-15/16 inches
(50mm) is required.)
- If the wall on the front side is over 59-1/16 inches (1,500mm) high, a clearance of (19-11/16 inches
(500mm) + h2/2) is required for the front side.
- If the wall on the rear side is over 19-11/16 inches (500mm) high, a clearance of (11-13/16 inches (300mm)
+ h1/2) is required for the rear side.
- When the units are surrounded by walls on more than two sides, observe the necessary clearance as
shown in the following illustrations.
- For walls on more than two sides, secure adequate clearance for service access space as shown in the
following illustrations.
- If the space between the unit and an obstacle above the unit is less than 59-1/16 inches (1,500mm) or
the space above the unit is closed, set up the duct at the air outlet side in order to prevent a short circuit.
- Make sure there is enough space in case the unit needs to be serviced and any of the four sides would
need to be opened or removed.
4.2 Service Space
NOTICE:
Refer to the Engineering Manual for the outdoor unit when installing the low ambient kit.
When an outdoor unit is installed, allow sufficient clearance as follows:
•
If there is insufficient clearance for air inlets and outlets, performance drop-off and mechanical issues due
to insufficient air intake may result.
•
Additionally, adequate clearance is required for service maintenance access.
