APPLICATION FLEXIBILITY
MODELS 5, 7-1/2 & 10 TON
These units are built in a single cabinet with two condensate
drain pans. This allows the units to be installed in either the
vertical or horizontal position for maximum flexibility.
On vertical applications, the air velocity across the cooling
coil keeps the condensate from dripping off the finned sur-
face onto the filters.
On horizontal applications, the unit must be installed with the
condensate drain pan under the entire cooling coil.
• The Supply Air Plenum and the Return Air Grill accesso-
ries can be used on either arrangement.
• The Base accessory can only be used on the vertical
arrangement.
Units installed horizontally are designed for ceiling suspen-
sion. Four 3/8"-16 weld nuts are provided in the angle sup-
ports on the front of the unit (the side with the logo).
Knockouts are provided in the exterior panels for access to
these weld nuts. The hanger rods must be supplied in the
field.
MODEL 15 TON
These units have two distinct modules . . . a blower module
and a coil module. Although the unit is always shipped in the
vertical position with a vertical air discharge as shown in illus-
tration (a), the blower module can be repositioned in the field
as shown in illustrations (b) and (c) for maximum flexibility.
• The Supply Air Plenum, Return Air Grill and Base acces-
sories can be applied on arrangement (a).
• The Return Air Grill and Base accessories can be
applied on arrangement (b).
• The Supply Air Plenum, Return Air Grill and Suspension
accessories can be applied on arrangement (c).
