Unit Features & Benefits
RKNL-B Series

Rheem Package equipment is designed from the ground up with
the latest features and benefits required to compete in today’s
market. The clean design stands alone in the industry and is a
testament to the quality, reliability, ease of installation and ser vice -
ability that goes into each unit. Outwardly, the large Rheem
Commercial Series™ label ( ) identifies the brand to the customer.
The sheet-metal cabinet ( ) uses nothing less than 18-gauge
material for structural components with an underlying coat of
G90. To ensure the leak-proof integrity of these units, the design
utilizes a one-piece top with a 1/8" drip lip (
), gasket-protected
panels and screws. The Rheem hail guard ( ) (optional) is its
trademark, and sets the standard for coil protection in the indus-
try. Every Rheem package unit uses the toughest finish in the
industry, using electro deposition baked-on enamel tested to
withstand a rigorous 1000-hour salt spray test, per ASTM B117.
Anything built to last must start with the right foundation. In this
case, the foundation is 14-gauge, commercial-grade, full-perime -
ter base rails (
), which integrate fork slots and rigging holes to
save set-up time on the job site. The base pan is stamped, which
forms a 1-1/8" flange around the supply and return opening and
has eliminated the worry of water entering the conditioned space
(
). The drainpan ( ) is made of material that resists the
growth of harmful bacteria and is sloped for the latest IAQ bene-
fits. Furthermore, the drain pan slides out for easy cleaning. The
insulation has been placed on the underside of the basepan,
removing areas that would allow for potential moisture accumula-
tion, which can facilitate growth of harmful bacteria. All insulation
is secured with both adhesive and mechanical fasteners, and all
edges are hidden.
During development, each unit was tested to U.L. 1995, ANSI
21.47, AHRI 340-370 and other Rheem-required reliability tests.
Rheem adheres to stringent IS0 9002 quality procedures, and
each unit bears the U.L. and AHRI certification labels located on
the unit nameplate (
). Contractors can rest assured that when
a Rheem package unit arrives at the job, it is ready to go with a
factory charge and quality checks. Each unit also proudly dis -
plays the “Made in the USA” designation.
Access is granted with 1/4 turn fasteners and hinged access
panels. Access to all major compartments is from the front of the
unit, including the filter and electrical compartment, blower com-
partment, furnace section, and outdoor section. Each panel is
permanently embossed with the compartment name (control/filter
access, blower access and furnace access).
Electrical and filter compartment access is through a large
hinged-access panel. The unit charging chart is located on the
inside of the electrical and filter compartment door. Electrical
wiring diagrams are found on the control box cover, which allows
contractors to move them to more readable locations. To the right
of the control box the model and serial number can be found.
Having this information on the
inside will assure model iden-
tification for the life of the
product. The production line
quality test assurance label is
also placed in this location
(
). The two-inch throwaway
filters ( ) are easily removed
on a tracked system for easy
replacement.
