(3) When the wall heights H1 and H3 exceed the limited value, keep dimensions for L1 and L3 as shown below.
L1 = H1 – 500
L3 = 300 + (H3–700) / 2
However, there is no limitation in wall height H3 if L3 exceeds 600.

Oblique blow 1,500 and

Up blow 800 and
(option) over
(4) The space of 1,500 mm per a series of 8 blower units is required for W4.
(Example : 5HP × 8units in series installation, 10HP × 4 units in series installation)
(5) When installing more than 3 rows with the oblique blow in lengthwise, change the blow direction of the group in the central row units,
excluding the both end rows, to the up blow (option). This group blows to the wall and also opposes to the units at the rear in the suction face.
For the example shown below, the uppermost group in the second row falls under the above notes.
Change to the up blow type
1st row
(Oblique blow is allowed.)
(6) Install the rack that stores the piping, etc. so that it does not interfere with the airflow entering into the heat exchanger.
(3) In the case where the unit is exposed to strong wind.
● Face the unit air outlet at a 90 ˚angle from the direction of the wind.
