Installation
Supply-Air Ductwork
Install the 1" (25.4 mm) supply-air
duct flange to the vertical and
horizontal equipment with the (8) 5/
16" (7.94 mm) factory supplied Torx®
head screws. The duct collar
assembly for each unit is located:
• Model GEH 1/2 to 5 ton = in a box
on the side of the unit
• Model GEV 1/2 to 10 ton = inside
of the refrigeration section of the
unit
• Model GEH 6 to 15 ton = of the
refrigeration section of the unit
• Model GEV 12 1/2 to 25 ton =
factory ship with a duct collar
installed for units containing a
top supply-air location. For units
with a back or front supply-air
location, the duct collar
assembly must be ordered
separately from the factory, or be
field provided.
When attaching the field ductwork to
the unit, provide a watertight flexible
connector at the unit to prevent
operating sounds from transmitting
through the ductwork. See Figure 46.
Elbows with turning vanes or
splitters are recommended to
minimize air noise due to turbulence
and to reduce static pressure.
Return-Air Ductwork
Install the 1"/2" (25.4/50.8 mm)
adjustable filter rack to the horizontal
equipment only with the use of (4) 5/
16" (7.94 mm) factory supplied Torx®
head screws. The vertical equipment
factory ships with the filter rack and
filter(s) installed.
When attaching the field ductwork to
the unit, provide a water tight flexible
connector at the unit to prevent
operating sounds from transmitting
through the ductwork. See Figure 47.
Elbows with turning vanes or
splitters are recommended to
minimize air noise due to turbulence
and to reduce static pressure.
