Carrier 50RHE006-060 specifications 50RHE Blower Speed Selection, 50RHE Blower Performance

PSC (PERMANENT SPLIT CAPACITOR) BLOWER SPEED SELECTION — All Water Source Heat Pumps are factory set to deliver rated airflow at nominal static (37 Pa) on medium speed. Where higher static is needed, high speed can be utilized (100 to 125 Pa). Low speed will deliver approximately 85% of rated airflow (25 Pa). The PSC blower fan speed can be changed on all units by swapping wires connected to the relay contacts that control the fan. See Table 4 and Fig. 14.

NOTE: Available airflow for all units is shown in Table 4.

Shaded areas are below minimum CFM. This data is provided for troubleshooting information only.

NOTES:

1.Units factory shipped on medium speed. Other speeds require field selection.

2.For dual voltage units, airflow is rated at lowest voltage.

3.Performance data shown is based n wet coil and clean air filter.
