Space and Location Requirements
For PTN models.
The most important consideration which must be taken into account
when deciding upon the location of air-cooled equipment is the provision
for a supply of ambient air to the condensing unit. Ignoring this essential
requirement will result in higher condensing pressure and contribute
to poor operation or potential equipment failure. Units must not be
located in the vicinity of steam, hot air or fume exhausts. Adequate
air circulation through the condensing unit is critical to ensure proper
equipment operation. Improper installation can damage the unit and will
void the warranty.
penthouse-style packaged units are designed
for indoor use only in ambient temperatures of 50°F to 100°F. The unit
cabinet is not approved for weather tight applications.
Another important consideration is that the unit should be mounted
away from noise sensitive spaces and must have adequate support to
avoid vibration and noise transmission into the building. Storage should
not be allowed on top of walk-in structure. Unit must not be enclosed
in an unventilated space.

Recommended Unit Placement
Some general rules for the evaporator section placement which
must be followed are:
1.
Ensure that the structural integrity of the box can
withstand the weight of the top mounted equipment.
2.
The air pattern must cover the entire room.
NEVER locate the evaporator section over doors.
3.
4.
Location of aisles, racks, etc. must be known.
5.
Never remove or unlock any panel cam-locks to
install top mounted equipment.
The size and shape of the storage will generally determine the type
and number of units to be used and their location.
