UNIT FEATURES & BENEFITS—RSKA- SERIES
Features Below Correspond to Photos on Page 3
1. All models feature Copeland® Scroll® compressors for maximum efficiency and quiet operation.
8. Refrigerant connections are conveniently located for easy
service diagnostics.
2. Louvered condenser compartment for protecting the coil
against yard hazards and/or weather extremes.
9. Condenser and evaporator coils feature enhanced fins
for better heat transfer and rifled copper tubing for
greater efficiency.
3. One-piece top with a drip lip to help keep water off of the unit
sides.
10. Supplemental electric heat strips up to 15 kW are available
(field or factory installed) for periods of extreme cold temperatures. Single point wiring makes installation even easier.
4. Supply and return air openings feature a one-inch tall flange
to prevent water migration into the ductwork.
11. All units feature an internal trap on the condensate line eliminating the need for installing an on-site external trap.
5. Access panels have “weep holes” and channels to further
help manage water run-off.
12. Integral gasketing on the base rails is standard on those
units shipped from the factory in the down-flow configuration.
6. Side and down discharge options available on all models.
13. Easily accessible control box.
7. Easily accessible blower section complete with slide-out
blower. All units feature a system matched MultiFlex® coil with
low static pressure drop and excellent cooling capacities.

GENERAL DATA—RSKA- SERIES
NOTES:
1. Cooling Performance is rated at 95° F ambient, 80° F entering dry bulb, 67° F entering wet bulb. Gross capacity does
not include the effect of fan motor heat. ARI capacity is net and includes the effect of fan motor heat. Units are suitable
for operation to 20% of nominal cfm. Units are certified in accordance with the Unitary Air Conditioner Equipment
certification program, which is based on ARI Standard 210/240 or 360.
2. EER and/or SEER are rated at ARI conditions and in accordance with DOE test procedures.
3. Outdoor Sound Rating shown is tested in accordance with ARI Standard 270.

*If a particular unit is to be converted to operate on LP (propane) for elevations above 2000 ft. [609.6 m] in Canada, the existing Natural Gas to LP Conversion Kits for the
subject models already contain the necessary orifices and instructions to de-rate the input for 2000-4500 ft. [609.6-1371.6 m] Canadian applications.

COMMON SUPPLY/RETURN
CONCENTRIC AIR DIFFUSER
SUPPLY/RETURN DIFFUSER
NOTE: The location of the combination supply and return diffuser should
not exceed 10 feet [3.05 m] above the floor level for units @ 1000 CFM
[472 L/s] or less and 12 [3.66 m] to 14 feet [4.27 m] above the floor level
for units with CFM greater than 1000 [472 L/s]. If the diffuser is installed
with a greater distance than recommended above, the supply air may
become stratified above the required comfort area causing uncomfortable conditions.
AIRFLOW/PRESSURE DROP
INFORMATION (INCHES W.C. [kPa])
Designed to convert a side by side or an over and under arrangement into a concentric distribution of air. The diffuser is flush
mounted, completely insulated, assembled, and internally baffled
to provide four way supply air distribution with a center return. To
make the assembly complete and ready to fit into a 2' [0.61 m] x
4' [1.22 m] suspended ceiling grid, the diffuser includes
adjustable supply louvers, hanging rings, anti-sweat gasket, and
round flanges for use with flexible ducts.

FRESH AIR DAMPER FOR USE ON
RSKA- SERIES
RXRF-FAA1 (Fixed - 0-35%)
The 0-35% manual outside Air Damper is designed to replace the
unit return air duct cover. No drilling or damper assembly is
required. The amount of outside air (0-35%) is controlled by simply adjusting the side damper.
RXRF-FAB1 (Motorized - 0-35%)
The 0-35% motorized outside Air Damper is designed to replace
the unit return air duct cover. No drilling or damper assembly is
required. The control motor opens the adjustable slide damper
when the unit blower motor is energized.
ECONOMIZERS
RXRE-CAA30 (3 Position) and
RXRD-CAM10 (Fully Modulating) for
RSKA- Series
RXRE-CAA30 (3 Position)
Provided with enthalpy control, and
mixed air sensor. Settings include
fully open, fully closed and adjustable
mid point.
RXRD-CAM10 (Fully Modulating)
Provided with enthalpy control, mixed
air sensor and minimum position potentiometer for proportioning (modulating)
the amount of fresh air.
Note: See economizer installation instructions for correct filter access door.
