DESCRIPTION
®
These outdoor condensing units are completely assembled, piped and
wired at the factory to provide one-piece shipment and rigging. Each
unit is pressurized with a holding charge of refrigerant-22 for storage
and/or shipping.
The compact design, clean styling, and quiet operation make these
condensing units suitable for almost any outdoor location. On rooftops
. . . because they weigh much less than a single package unit of simi-
lar capacity and are much easier to rig and support. At ground level. . .
because their ample sub-cooling capacity allows them to be located 18
meters (60 feet) below the evaporator coil.
All sheet metal parts are constructed of commercial grade (G90) gal-
vanized steel. Before painting, each part is thoroughly cleaned to
remove any grease or dirt from its surfaces. The external parts are
then coated with a powder paint to assure a quality finish for many
years. This coating system has passed the 100 hour, salt spray test
per ASTM Standard B117.
All models include a 1-year limited warranty on the complete unit. The
compressor carries an additional 4-year warranty.
A matching line of Evaporator Blower units is also offered to meet your
precise capacity and air handling requirements.
FEATURES
• Condenser coil constructed of rifled copper tubes and louvered
O
aluminum fins for durability and long lasting efficient operation.
O
• Permanently attached base rails with fork lift slots and lifting
holes. This design allows for 3-way fork lift access and overhead
O
rigging.
• Both high and low pressure controls.
• Solid state motor protection to prevent the compressor from oper-
ating at an unsafe condition.
• Ball bearing condenser fan motors with 1/2 inch shafts.
• Color-coded power and control wiring for easier service and trou-
bleshooting.
• Anti-short cycle timer to protect the compressor.
• A lockout circuit to prevent the unit from cycling on safety control.
• A 24-volt temperature control circuit.
• Standard unit low ambient operation to (35°F).
• A filter-drier (shipped in the unit's compressor compartment for
field installation near the evaporator coil).
• Service valves with a back-seating access port for pressure test-
ing the system. Copper stub-outs are factory mounted on the suc-
tion and liquid service valves to simplify the field piping
connections.
• Exterior access to service pressure port connections.
• Packaging suitable for outdoor storage.
• An optional Phenolic coating is available where the condenser
coils are fully dipped in a phenolic coating process to provide
longer life in corrosive conditions.
