HORIZONTAL UNITS (50PTH)

Horizontal units are designed for indoor installation only. Be sure
to allow adequate space around the unit for installation and servic-
ing. See Fig. 1 and 2 for overall unit dimensions.

VERTICAL UNITS (50PTV)

Vertical units are designed for indoor installations only. Vertical
units are typically installed in a floor-level closet or a small me-
chanical room, Be sure to allow adequate space around the unit for
installation and servicing. See Fig. 3 for overall unit dimensions.
CAUTION
EQUIPMENT DAMAGE HAZARD
To avoid equipment damage, do not use these units as a source
of heating or cooling during the construction process. The me-
chanical components and filters used in these units quickly be-
come clogged with construction dirt and debris which may
cause system damage.

INSTALLATION GUIDELINES (ALL UNITS)

1. Be sure that the location chosen for unit installation provides
ambient temperatures maintained above freezing.
2. Be sure the installation location is isolated from sleeping
areas, private offices, and other acoustically sensitive spaces.
3. Be sure unit is mounted at a height sufficient to provide an
adequate slope of the condensate lines. If an appropriate slope
cannot be achieved, a field-supplied condensate pump may
be required.

4. On horizontal units, allow adequate room below the unit for
condensate drain trap and do not locate the unit above supply
piping.
5. Provide sufficient space for duct connection. Do not allow the
weight of the ductwork to rest on the unit.
6. Provide adequate clearance for filter replacement and drain
pan cleaning. Do not allow piping, conduit, etc. to block filter
access.
7. Provide sufficient access to allow maintenance and servicing
of the blower and blower motor, compressor, refrigerant cir-
cuit, controls, and coils.
8. For units with free return (non-ducted), provide adequate
space for proper return airflow. For units installed in closets
or mechanical rooms, provide sufficient return grill area for
proper airflow.
9. Provide ready access to water valves and fittings, and screw-
driver access to unit side panels, discharge collar, and all elec-
trical connections.
10. Where access to side panels is limited, pre-removal of the
control box side mounting screws may be necessary for
future servicing.
11. For units that are installed in enclosed spaces (such as furred
in closets or behind finished ceilings), provide access panels
to allow for the installation, maintenance, service, and
removal of the unit. See Fig. 4 for Service Clearance require-
ments.
