AVOID:
● heat sources, exhaust fans, etc. (Fig. 1-4)
● damp, humid or uneven locations
DO:
● choose a place as cool as possible.
● choose a place that is well ventilated and outside
air temperature does not exceed maximum 45°C
constantly.
● allow enough room around the unit for air intake/
exhaust and possible maintenance. (Fig. 1-5)
● use lag bolts or equal to bolt down unit, reducing
vibration and noise.

In case of multiple installations
● provide a solid base (concrete block, 10 × 40 cm
beams or equal), a minimum of 15 cm above
ground level to reduce humidity and protect the unit
against possible water damage and decreased ser-
vice life. (Fig. 1-7)
● use lug bolts or equal to bolt down unit, reducing

CAUTION
● Concerning inlet-side distance “C” (Fig. 1-5)
The minimum for distance “C” is 15 cm if there are no obstructions on the outlet side
(wall *1 side) and *2 or *4 is not present. In all other cases, the minimum for distance
“C” is 20 cm.
● If the unit is installed with the outlet side facing wall *1, then there must be no obstruc-
tions on 2 of the remaining 3 sides: *2, *3, *4.
● If wall *1 is on the outlet side (Fig. 1-5), or if obstructions are present on all 3 sides *2,
*3, and *4 (Fig. 1-5), then the minimum distance for “A” and “B” is 2 m (Fig. 1-6). Even
if there is no wall on the outlet side, a minimum of 100 cm is required.
