APPLICATION FLEXIBILITY
INDOOR UNITS - FEH090 & 120
OUTDOOR UNITS - EFB090 & 120
These outdoor units are lightweight and can be installed on almost
any roof.
Units can be lifted using nylon straps with hooks at the holes
provided in the base rails, or they may be lifted with a forklift through
the slotted openings in the base rails.
A quality appearance and low sound levels make these units
suitable for most ground level locations.
Remember that during heat and defrost cycles, condensate will drip
from the underside of the unit coils and that this condensate will
freeze when the temperature of the outdoor air is below 32
°
F. A
gravel bed or some other means of handling this condensate may
have to be provided.
These indoor 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.
•
The Supply Air Plenum and the Return Air Grille accessories
can be used on either arrangement.
•
T h e Base accessory can only be used on the vertical
arrangement.
Units installed horizontally are designed for ceiling suspension.
Four 3/8" - 16 weldnuts are provided in the angle supports on the
front of the unit. Knockouts are provided in the exterior panels for
access to these weldnuts. The hanger rods must be supplied in the
field.
On vertical applications, the air velocity across the indoor coil
keeps the condensate from dripping off the finned surface onto the
filters.
On horizontal applications, the unit must be installed with the
condensate drain pan under the entire indoor coil.
