II. INSTALLATION
Introduction
NOTE: Read the entire instruction manual before starting
the installation.
The OES/OHS series air conditioners and heat pumps are
ETL and c-ETL listed and are available in the cooling/electric
heating sizes shown in Table 5 on page 13. This series of
units is designed for outside installation only.
The OES/OHS series air conditioners and heat pumps are
self-contained units. All components, including outdoor coil,
compressor, and refrigerant tubing, are located in a single
package. The units are already piped, charged, and wired.
Refer to Figure 2 on page 3 for basic unit dimensions.
The OES/OHS series air conditioners and heat pumps are
designed for installation in various light commercial applications.
These instructions detail a typical method of installation. These
units can be installed with or without ductwork. Installed
flanges can be used for attaching ductwork or covered with a
decorative grille. OES/OHS series units come from the factory
with two 1" air filters installed. Simply bend tabs on filter rack
to accommodate 2" filters. Return filter grills are offered as
an accessory option. If a different or additional air filters are
required, they will need to be field-installed in the duct system.
These units have 2" long duct flanges for connecting to the
field ducts.
Safety Considerations
