weatherproof flexible connectors on both supply and return
connections at the unit to reduce noise transmission is
recommended.
It is preferable to install the unit on the roof of the structure
if the registers or diffusers are located in the wall or ceiling.
A slab installation is recommended when the registers are
low on the wall or in the floor.
Connecting the Return and Supply Flexible Duct in
Manufactured or Modular Housing Application
The return and supply fittings are to be attached at
the unit to a suitable square to round duct converter.
Your distributor has a factory designed square to round
converter transition. The model #’s of these kits are
as follows: Small Chassis 27.5” SQRPCH102, Large
and Extra Large Chassis 32.5:” and 36” SQRPCH103
(See Specification Sheets for Dimension details). The
SQRPCH101 has 14” duct collar on supply and 16” duct
collar (equivalent diameter, opening is oval) on the return.
The SQRPCH102 and SQRPCH103 have 14” duct collar
on supply and 18” duct collar (equivalent diameter, opening
is oval) on the return. The collars are to be slipped into the
openings, and the flanges bent around the converter. The
square to round converter is attached to the flanges of the
square duct openings. The flexible duct is then clamped on
to the collars. Once the duct is affixed to the unit, seal the
collars and flanges with a proper waterproof sealant
(See Figure 4).

It is strongly encouraged to use appropriately sized ducts
based upon the CFM for your application (unit’s CFM). If
duct sizing through industry manuals or air duct calculators
require larger ducts than converter openings, run larger
duct size up to unit converter openings and reduce with a
reducer duct fitting or transition right at the unit.
Plenum Application
A suitable plenum or square duct must be constructed. The
duct cross-sectional area should be determined by industry
duct sizing manuals or air duct calculators.
On ductwork exposed to outside air conditions of
temperature and humidity, use an insulation with a good
K factor, and a vapor barrier. Industry practices should be
followed. Balancing dampers are recommended for each
branch duct in the supply system. Ductwork should be
properly supported from the unit.
NOTE: Proper sealing of all duct work and air
handling compartments is extremely important to
overall unit efficiency.
Filters
Filters are not provided with unit, and must be supplied
and installed in the return duct system by the installer.
A field installed filter grille is recommended for easy and
convenient access to the filters for periodic inspection
and cleaning. Filters must have adequate face area
for the rated quantity of the unit. See table below for
recommended filter size.

must be level or slightly inclined toward drain.
ELECTRICAL WIRING
CAUTION
To avoid property damage or personal injury due to fire, use
only copper conductors.
All wiring should be made in accordance with the National
Electrical Code. The local Power Company should
be consulted to determine the availability of sufficient
power to operate the unit. The voltage, frequency, and
phase at the power supply should be checked to make
sure it corresponds to the unit’s RATED VOLTAGE
REQUIREMENT.
