4. Locating TheUnit
The unit is designed for outdoor installation only. The unit
may be installed on a concrete slab (or other adequate plat-
form) at ground level, oron a rooftop with an adequate plat-
form or a roof curb. Typical installations are shown in
FIGURE 3 through FIGURE 5.
Access Panels
CAUTION
Unit will NOT operate properly without all access pan-
els in place.
Unit MUST NOT be moved unless all access panels are
in place.
Avoid installations under roof overhangs without guttering.
Water draining from the roof onto the unit could produce ex-
cessive noise, and may cause ice to build up on coil or fan.
See FIGURE 1 on page 5 for a general view of unit and
location of access panels.
Clearances
Roof top installations are acceptable providing the roof will
support the unit and provisions are made for water drain-
age and for the noise or vibration through the structure.
The location MUST allow for minimum clearances and
should not be adjacent to a patio or other area where the
unit's operating sound level might be objectionable. Local
codes MUST be observed.
Minimum clearances, as specified below and in FIGURE 2,
MUST be maintained from adjacent structures to provide
adequate air circulation and room for service personnel.
