Unit Features & Benefits
RKNL-B Series
7
The compressor
compartment
houses the heart-
beat of the unit. The
scroll compressor
(
) is known for its
long life, and for
reliable, quiet, and
efficient operation.
The suction and
discharge lines are
designed with
shock loops (
) to
absorb the strain
and stress that the
starting torque,
steady state opera-
tion, and shut down
cycle impose on the
refrigerant tubing.
Each compressor
and circuit is inde-
pendent for built-in
redundancy, and
each circuit is clearly marked throughout the system. Each unit
has two stages of efficient cooling operation, first stage is
approximately 50% of second stage. (073 single stage)
Each unit comes standard with filter dryer . The condenser fan
motor ( ) can easily be accessed and maintained through the
blower compartment. The polarized plug connection allows the
motor to be changed quickly and eliminates the need to snake
wires through the unit.
The outdoor coil uses the latest enhanced fin design ( ) for the
most effective method of heat transfer. The outdoor coil is pro-
tected by optional* louvered panels, which allow unobstructed
airflow while protecting the unit from both Mother Nature and
vandalism.
Each unit is designed
for both downflow or
horizontal applications
(
) for job configura-
tion flexibility. The
return air compartment
can also contain an
economizer (
). Two
models exits, one for
downflow applications, and one
for horizontal applications. Each unit is
pre-wired for the economizer to allow quick
plug-in installation. The economizer is also available
as a factory-installed option. Power Exhaust is easily field-
installed. The economizer, which provides free cooling when
outdoor conditions are suitable and also provides fresh air to
meet local requirements, comes standard with single enthalpy
controls. The controls can be upgraded to dual enthalpy easily in
the field. The direct drive actuator combined with gear drive
dampers has eliminated the need for linkage adjustment in the
field. The economizer control has a minimum position setpoint,
an outdoor-air setpoint, a mix-air setpoint, and a CO
2
setpoint.
Barometric relief is standard on all economizers. The power
exhaust is housed in the
barometric relief opening
and is easily slipped in with
a plug-in assembly. The wire
harness to the economizer
also has accommodations
for a smoke detector.
The Rheem roofcurb
(
) is made for
toolless assembly at
the jobsite by engag-
ing a pin into the
hinged corners of adjacent
curb sides, which makes the assembly process quick and easy.
