Rheem RKKB SERIES, Owner'S Manual, Page: 3 / 68

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 service-
ability that goes into each unit. Outwardly, the large Rheem
Com-
mercial Series TM 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 ( ) is its trademark,
and sets the standard for coil protection in the industry. 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. The insulation has been placed on the underside of the
basepan, removing areas that would allow for potential moisture
accumulation, which can facilitate growth of harmful bacteria. All
insulation is secured with both adhesive and mechanical fasten-
ers, and all edges are hidden.
During development, each unit was tested to U.L. 1995, ANSI
21.47, ARI 340-370 and other Rheem-required reliability tests.
Rheem adheres to stringent IS0 9002 quality procedures, and
each unit bears the U.L. and ARI 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 to all major compartments is from the front of the unit,
including the filter and electrical compartment, blower compart-
ment, furnace section, and outdoor section. Each panel is per-
manently embossed with the compartment name (control/filter
access, blower access and furnace access).
Electrical and filter compartment access is through a large, tool-
less, hinged-access panel. On the outside of the panel is the unit
nameplate, which contains the model and serial number, electri-
cal data and other important unit information.
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 identification for
the life of the product.
The production line qual-
ity test assurance label is
also placed in this loca-
tion (
). The two-inch
throwaway filters ( )
are easily removed on a
tracked system for easy
replacement.
