2 And air handlers to provide a com-plete system Easier Installation - Independent panels provide quickaccess for unit setup. Installation time is reduced by easypower and control wiring access. Select indoor matches withfactory-mounted TXVs are available for quicker systeminstallation. The factory installed filter-drier and factorycharge for a 15-Ft lineset means less time spent brazing andcharging the system. The small base dimension and reducedunit clearances make for easier retrofits. Durable Finish - The coated steel wire fan guard, coatedexternal fasteners, and pre-treated G90-equivalent galva-nized steel chassis components resist corrosion and rustcreep.

3 Powdercoat paint further protects external panels. Louvered Coil Protection - Two stamped steel louveredpanels protect the coil from mechanical damage. Quality Coils - The high efficiency microchannel aluminumcoil is manufactured using an improved material system pro-viding reliable performance and small unit size. Protected Compressor - Compressors are protected inter-nally by a high pressure relief valve and a temperature sen-sor, and externally by the system high pressure switch. Theliquid line filter-drier is factory installed to protect the com-pressor against moisture and debris. Environmentally Friendly - CFC-free R-410A refrigerantdelivers environmentally friendly performance with zeroozone depletion.

4 Top Discharge - Warm air is blown up, away from the struc-ture and any landscaping and allows compact location onmulti-unit applications.

The Unit Charge is correct for the outdoor unit, smallest matched indoor unit, and 15 feet of refrigerant tubing. For tubing lengths other than 15 feet, add or subtract the amount of refrigerant, using the difference in actual lineset length (not equivalent length) multiplied by the per foot - 143 - 124 - 34 - 145 - 24 - 155 - 12 Charge Per Foot, Weight models are shipped with a Hard Start Kit installed at the $ $DIMENSIONSUnitModelDimensions(Inches)Re frigerant ConnectionService Valve SizeABCL iquidVaporRAC14L18B21S33-1/424243/83/4 RAC14L24B21S3029-1/429-1/4 RAC14L30B21S3029-1/429-1/4 RAC14L36B21S36-1/429-1/429-1/4 RAC14L42B21S33-1/435-1/431-3/47/8 RAC14L48B21S33-1/435-1/431-3/4 RAC14L60B21S36-1/43834-1/47/8 5006078-UTG-D-10164 johnson Controls Unitary ProductsCHARGING PROCEDURES:1.

9 Check the Factory Unit Charge listed on the unit nameplate to verify the refrigerant charge for the outdoor unit, the smallest matched indoor unit, and the 15 feet ofinterconnecting lineset. 2. Verify the indoor metering device and additional charge required for the specific matched indoor unit in the system using the above table. 3. Add additional charge for the amount of interconnecting lineset greater than 15 feet at the rate specified in the Physical and Electrical For installations requiring additional charge, weigh in refrigerant for the specific matching indoor unit and actual lineset length. 5. Once the charge adders for matched indoor unit and for lineset have been weighed in, verify the system operation against the temperatures and pressures in the Charging Chart for the outdoor unit.

10 Locate Charging Charts on the outdoor unit and also in the Service Data Application guide on Follow the Subcool or the Superheat charging procedure in the Installation Manual according to the type of indoor metering device in the system, and allow ten minutes after each charge adjustment for the system operation to stabilize. Record the charge adjustment made to match the Charging Chart. 6. Permanently stamp the unit data plate with the TOTAL SYSTEM CHARGE defined as follows: TOTAL SYSTEM CHARGE = Base Charge (as shipped) + charge adder for matched indoor unit + charge adder for actual lineset length + charge adjustments to match the Charging CHARGE FOR VARIOUS MATCHED SYSTEMS Outdoor Unit RAC14L18B21 SRAC14L24B21 SRAC14L30B21 SRAC14L36B21 SRAC14L42B21 SRAC14L48B21 SRAC14L60B21 SRequired TXV 1,2BA1BA1BB1BC1BC1BC1BD1 Indoor Unit 3,4,5 Additional Charge, ozRFCX18BP0 RFCX24BP30 RFCX30BP1072 RFCX36BP10720 RFCX36CP 1122 RFCX42CP 11220 RFCX48(CP,DP) 520 RFCX60(CP,DP) 920 RFCX18BE0 RFCX24BE30 RFCX30BE850 RFCX36(BE,CE)10720 RFCX42CE 52 RFCX48(CE,DE)
