Contents

26PRE-START-UPSystem Checkout — After completing the installation,and before energizing the unit, the following system checksshould be made prior to initial startup:1. Verify that the supply voltage to the heat pump is in ac-cordance with the nameplate ratings.2. Verify that the control transformer is set to the correctvoltage for 208/230V units (factory setting is 230V).3. Make sure that all electrical connections are tight and se-cure.4. Check the electrical fusing and wiring for the correct size.5. Verify that the low voltage wiring between the thermostatand the unit is correct.6. Verify that the water piping is complete and correct.7. Check that the water flow is correct, and adjust if neces-sary.8. Check the blower for free rotation, and that it is secured tothe shaft.9. Verify that vibration isolation has been provided.10. Unit is serviceable. Be certain that all access panels aresecured in place.11. Verify that the blower shipping support has beenremoved.12. Verify that ductwork has been properly fastened to supplyand return duct collars.13. Make sure return air filters are positioned correctly in thefilter rack if removed during installation.14. Verify that the unit is not in TEST mode.AIR COIL — To obtain maximum performance, clean the aircoil before starting the unit. A ten percent solution of dish-washer detergent and water is recommended for both sides ofthe coil. Rinse thoroughly with water.PSC (Permanent Split Capacitor) BlowerSpeed Selection — The PSC blower fan speed can bechanged by moving the blue wire on the fan motor terminalblock to the desired speed. The 50PC units are designed todeliver rated airflow at nominal static (0.15 in. wg) on mediumspeed (factory setting) and rated airflow at a higher static (0.4to 0.5 in. wg) on high speed for applications where higherstatic is required. Low speed will deliver approximately 85%of rated airflow at 0.10 in. wg.NOTE: Blower performance is shown in Tables 11 and 12.Table 11 — 50PCH,PCV (007-070), 50PCD (015-070) PSC Blower PerformanceNOTE: 575V models employ 1 speed motors (high only).50PCUNIT FANSPEED RATEDAIRFLOWAIRFLOW (cfm) AT EXTERNAL STATIC PRESSURE (in. wg)0.10 0.20 0.30 0.40 0.50 0.60 0.70 0.80 0.90 1.00 1.10 1.20007Low300370 340 295 250 — — — — — — — —Med 390 360 330 300 260 — — — — — — —High 410 380 350 315 280 210 — — — — — —009Low350370 340 295 250 — — — — — — — —Med 390 360 330 300 260 — — — — — — —High 410 380 350 315 280 210 — — — — — —012Low400300 290 290 300 — — — — — — — —Med 380 380 360 330 290 — — — — — — —High 420 400 380 360 340 320 — — — — — —015Low500500 450 400 — — — — — — — — —Med 560 520 480 430 400 — — — — — — —High 700 650 600 550 500 450 400 — — — — —018Low650— — — — — — — — — — — —Med 810 790 760 730 680 590 — — — — — —High 1010 970 920 870 800 680 530 — — — — —024Low850650 610 570 540 510 — — — — — — —Med 830 820 800 770 720 620 — — — — — —High 1050 1000 950 910 840 710 570 — — — — —030Low 950(50PCV/D)865(50PCH)740 730 700 660 610 — — — — — — —Med 830 810 770 730 680 620 — — — — — —High 1000 950 900 830 750 690 630 — — — — —036Low12001290 1250 1200 1150 1080 1000 — — — — — —Med 1410 1350 1290 1220 1150 1060 900 — — — — —High 1500 1440 1370 1290 1210 1120 1000 900 — — — —041Low1300950 900 840 780 720 700 — — — —Med 1200 1140 1080 1010 930 870 820 — — — —High 1490 1400 1320 1240 1160 1080 990 910 — — — —042Low14001210 1210 1190 1160 1120 1080 — — — — — —Med 1460 1450 1430 1390 1330 1250 1160 — — — — —High 1750 1710 1670 1620 1560 1460 1330 1210 1080 — — —048Low16001450 1440 1420 1400 1360 1320 — — — — — —Med 1700 1670 1630 1580 1530 1470 1400 — — — — —High 1930 1870 1810 1740 1670 1600 1520 1430 1340 — — —060 N/A070Low21001570 1560 1550 1540 1530 1505 1475 1440 1400 — — —Med 1900 1890 1880 1870 1860 1825 1790 1730 1670 1590 1500 —High 2240 2220 2200 2150 2100 2050 2000 1940 1870 1800 1700 1590
