Fan motor furnished with inherent thermal protection.3. To be wired in accordance with National Electric Codeand local codes.4. Outdoor unit control requires a minimum of 27 VA,24 VAC control power.5. Use copper conductors only. use conductors suitablefor at least 75°C (167°F).6. If indoor section has a transformer with a groundedsecondary, connect the grounded side to "C".7. If any of the original wire, as supplied, must be replaced,use the same or equivalent wire.8. Check all electrical connections inside control box fortightness.9. Do not attempt to operate unit until service valves havebeen opened (back seated)10.Must use thermostat listed in pre-sale literature.11.Compressor windings shown for 2 cylinder operation.For 1 cylinder operation reverse R and S markings.5STARTCAP1STARTRELAY2RVSD C C PL1 1 2 3 4 5 1 2HP/AC C SEV RVS C HI LO PL2CHCOMPCAPA B C DCHRSLPS1PL3 23HPS1PL4 2OAT 12PL54OCT 5VCBRNVHBLUODFBLKL 2YELCCHREDCOMPCL-t°-t°CLPSHPSOATOCTCHVPSL223OFMFANCAPCCHREDBLUDUAL CAPACITYCONNECTION DIAGRAM L1BLK208 / 230 - 1 - 60L2YELPOWER SUPPLYORN ORNBLKCH13 11EQUIP GND23 21RVSBRNBRNPL1 1 2 3 4 5 1 2HP/AC C SEV RVS C HI LO PL2OY 2Y1W1CRUFORCEDDEFROSTDEFROSTTIME (MIN)PL5COMM STATUS OCTA B C DLPSPL3HPSPL4123121245VCBRNVHBLUODFBLKL 2YELCCHREDYEL/PNKYEL/PNKBLU/PNKYELBLULPSHPSBLU/PNKOAT-t°BLKBLKOCT-t°BRNBRNBLKBRNYELVPSBLKBRNCCH5CLBLKSTARTCAPSTARTRELAYYEL12BRN1121COMPCAPBLUYELFAN CAPBRNTO INDOOR UNIT-LEGEND-COMPONENT ARRANGEMENTFACTORY POWER WIRINGCOMM SYSTEM COMMUNICATIONFIELD POWER WIRINGCOMP COMPRESSORFIELD CONTROL WIRINGHPS HIGH PRESSURE SWITCHFACTORY CONTROL WIRINGCHSTARTCOMPONENT CONNECTIONLPS LOW PRESSURE SWITCHCLRELAYFIELD SPLICEOAT THERMISTOR (OUTDOOR AIR)DUAL CAPACITYJUNCTIONOCT THERMISTOR COILCONTROLCOMPCL CONTACTOR LOW CAPACITY (24 V COIL)OFM OUTDOOR FAN MOTORCAPSTARTFANCCH CRANKCASE HEATERCAPCAPCH CONTACTOR HIGH CAPACITY (24 V COIL)RVS REVERSING VALVE SOLENOIDCAP CAPACITORSTATUS SYSTEM FUNCTION LIGHTDCC DUAL CAPACITY CONTROLVPS VAPOR PRESSURE SWITCHUNIT OPERATION/SEE UNIT INSTALLATION INSTRUCTIONS FOR DETAILS1 MINUTE TIME DELAY - WHEN CHANGING FROM LOW TO HIGH, OR HIGH TO LOW, THERE IS A 1 MINUTE TIME DELAY.
