Unit Features & BenefitsRLKN-B Series
• R-410A HFC refrigerant.• Complete factory charged, wired and run tested.• Scroll compressors with internal line break overload and
high-pressure protection.• Two-stage compressor on all models.• Convertible airflow.• TXV refrigerant metering system.• High Pressure and Low Pressure/Loss of charge protection
standard on all models.• Solid Core liquid line filter drier on each circuit.• Single slab, single pass designed evaporator coil facilitates
easy cleaning for maintained high efficiencies.• Cooling operation up to 125 degree F ambient.• Easily removable filter, blower, electric heat, and control
access panels permits prompt service.• Powder Paint Finish meets ASTMB117 steel coated on each
side for maximum protection. G90 galvanized.• One piece top cover and one piece base pan with drawn
supply and return opening for superior water management.• Externally mounted refrigerant gauge ports for easy service
diagnostics.
• Factory or field-installed electric heat kits available upto 24 kW.
• Easy to install plug-in; slip in, 100% fully modulatingeconomizer.
• Forkable base rails for easy handling and lifting.• Single point electrical and gas connections.• High performance belt drive motor with variable pitch pulleys
and quick adjust belt system.• Permanently lubricated evaporator, condenser and gas heat
inducer motors.• Condenser motors are internally protected, totally enclosed
with shaft down design.• 2 inch filter standard with slide out design.• Colored and labeled wiring.• Molded compressor plug.• Micro Channel evaporators and condenser delivers superior
performance with less refrigerant charge and less weight thanconventional copper tube/aluminum fin coils In addition thealuminum design has superior formicary corrosion protectionand less potential for leaks due to elimination of tube rubbingpotential. Its easier to clean and has a more robust surface.

Selection ProcedureRLKN-B Series
RLKN-B SELECTION PROCEDURES1. Determine cooling and heating requirements at design
conditions. Example: Total cooling capacity ............61,000 BTUH [17.87 kW] Sensible cooling capacity ......44,000 BTUH [12.89 kW] Condenser entering air ..........95°F [35°C] Evaporator entering air............63°F [17°C] wb/76°F [24°C] db Indoor air flow ........................2100 CFM [991 L/s] External static pressure..........1.0 in W.G.
2. Select unit to meet cooling requirements.Since total cooling is within the range of 6 ton [21.1 kW] unitenter cooling performance from the RLKN-B073 table, at95°F [35°C] outdoor temperature, 63°F [17°C] wb enteringindoor air, and 2100 CFM [991 L/s]:
Total capacity..........................65,000 BTUH [19.1 kW] Sensible Capacity ..................55,400 BTUH [16.2 kW] Power input ............................5.3 kW
And also, at 76°F [24°C] db indoor entering air, and using the formula at the bottom of the page: Sensible capacity....................48,008 BTUH [14.07 kW]
3. Determine blower speed and power to meet the systemrequirements.At the given external static pressure of 1.0 in W.G., the beltmodel must be selected. Enter the belt drive blower perfor-mance table at 2100 CFM [991 L/s] and 1.0 in W.G. ESP:
RPM....................1100 Watts ..................1025 Drive ..................L
4. Calculate indoor blower BTUH heat effect. BTUH = Watts x 3.413 = 3498
5. Calculate net cooling capacities. Net total cooling = 65,000 – 3498 = 61,502 BTUH [18.02 kW] Net sensible cooling = 48,008 – 3498 = 44,510 BTUH
