DESCRIPTION
Both the outdoor and indoor units are completely piped and
wired at the factory and are shipped ready for immediate
installation. Only the interconnecting liquid and suction lines,
control wiring, and the main power wiring are required to
complete the installation. Every outdoor unit is dehydrated,
evacuated, leak tested and pressure tested at 450 psig
before being pressurized with a holding charge of refrigerant-
22 for shipment and/or storage.
To eliminate the costly cabinet deterioration problems usually
associated with outdoor equipment, all sheet metal parts are
constructed of commercial grade (G90) galvanized steel.
After fabrication, each part is thoroughly cleaned to remove
any grease or dirt from its surfaces. The parts that will be
exposed to the weather are then coated with a desert sand
powder paint to assure a quality finish for many years. This
coating system has passed the 750-hour, salt spray test per
ASTM Standard B117.
APPLICATION FLEXIBILITY OUTDOOR
The 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.
APPLICATION FLEXIBILITY INDOOR
The indoor units are built in a single cabinet with one conden-
sate drain pan. These units can be installed in either the verti-
cal or horizontal position for maximum flexibility.
NOTE: On vertical applications, the air velocity across the
indoor coil keeps the condensate from dripping off
the finned surface onto the filters.
NOTE: On horizontal applications the unit must be installed
with the condensate drain pan under the entire
indoor coil.
NOTE: The Supply Air Plenum and the Return Air Grille
accessories can be used on either arrangement.
NOTE: The Base accessory can only be used on the verti-
cal arrangement.
