AIR COIL — To obtain maximum performance, clean the air
coil before starting the unit. A ten percent solution of dish-
washer detergent and water is recommended for both sides of
the coil. Rinse thoroughly with water.
PSC (Permanent Split Capacitor) Blower
Speed Selection —
All water source heat pumps are
factory set to deliver rated airflow at nominal static (0.15 in.
wg) on medium speed. Where higher static is needed, high
speed can be utilized (0.4 to 0.5 in. wg). Low speed will
deliver approximately 85% of rated airflow (0.10 in. wg). The
PSC blower fan speed can be changed on all units by swapping
wires connected to the relay contacts that control the fan. See
Fig. 27.
FOR 50RHR,RVR,RHS,RVS AND RDS UNITS — On the
control, the black wire is connected to High, blue wire is
connected to Medium and red wire is connected to Low. See
Fig. 19-22.
NOTE: Available airflows for all units are shown in Tables 8-13.
FOR 50RHC,RVC UNITS — The PSC blower fan speed
can be changed by moving the blue wire on the fan motor ter-
minal block to the desired speed as shown in Fig. 27. The
50RHC,RVC units are designed to deliver rated airflow at
nominal static (0.15 in. wg) on medium speed (factory setting)
and rated airflow at a higher static (0.4 to 0.5 in. wg) on high
speed for applications where higher static is required. Low
speed will deliver approximately 85% of rated airflow at
0.10 in. wg. An optional ‘High Static’ blower is available by
using the special option code in the model nomenclature.

filter.
3. All units ARI/ISO/ASHRAE 13256-1 rated on high fan speed.
4. Only two-speed fan (H & M) available on 575-v units.
