1. Choose a place as cool as possible.
The place should be well ventilated
and the inlet air should not hotter
than the outside temperature (max
45 O C or 113 O F).
2. Avoid the vicinity of heat sources,
exhaust fan, etc.
3. Avoid direct sunlight, provide
awnings if necessary.
4. The unit should be set on a level
reinforced concrete pad to avoid
the effect humidity. The minimum
height of the concrete pad should
be 100 mm. (4"). Unit shall be fixed
securely to the concrete pad with
bolts (not supplied) to prevent
abnormal noise and vibration.
5. The concrete pad must be
positioned a minimum of 200 mm.
(8") from any well and surrounding
shrubbery.

side of the unit must be 250 mm.
(10") : 1200 mm. (48") on the
discharge air side of the unit and
250 mm. (10") on the tubing side
of the unit (Figure 1).

be sure the roof will carry the unit's
weight. Vibration isolation is
recommended to prevent
transmission to the building
structure.
