3-speed direct-drive fan motor. The 6-ton unit has a single
speed direct-drive fan motor. Belt-drive blowers are also
available on all 3, 4, 5 and 6-ton models.
FULL PERIMETER BASE RAILS -
The permanently attached
base rails provide a solid foundation for the entire unit and
protect the unit during shipment. The rails provide fork lift
access from 3 sides, and rigging holes are also provided so
that an overhead crane can be used to place the units on a roof.
SYSTEM PROTECTION -
Internal overload protection are
standard on all scroll compressors. Every unit has a liquid line
filter-drier, high and low pressure/lose at charge switches and a
suction line freezestat to protect all system components. All units
will provide cooling at ambient temperatures down to 45°F.
UTILITY CONNECTIONS MADE EASY -
Gas and electric
utility knockouts are provided in the unit base as well as the
side of the unit. A clearly identified location is provided to mount
a field supplied electrical disconnect switch. Utility connections
can be made quickly and with a minimum amount of field labor.
SIMPLE CONTROL CIRCUIT -
A low voltage printed circuit
board contains a scroll compressor lockout indicator light and
a low voltage terminal strip. An additional set of pin connectors
is also provided to simplify the field interface of external
controls. Mate-n-lock plug connectors are used where line and
low voltage wires pass thru internal bulkheads. This allows for
easier troubleshooting and component replacement. The
electrical control box is not located in the scroll compressor
compartment so the access cover can be removed for
troubleshooting without affecting the normal system operating
pressures. All wiring internal to the unit is color/number coded.
AIR FILTERS -
Units are shipped with 1" disposable filters. The
unit filter racks can accommodate 1" or 2" filters without any
modifications.
