WIRING

CAUTION

Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment 
circuitry.
Disconnect power supply before wiring.

IMPORTANT

All wiring must comply with applicable codes and 
ordinances.

MV876

Mount the 24 Vac transformer and wire as shown in Fig. 14. 

Reconnect power to the system. When the system is 
powered, the MV876 will run through one backwash cycle 
(approximately 20 seconds).

Set MV876 backwash interval to the desired setting. See the 
Operation section.

Check MV876 operation by interrupting primary power to the 
transformer. When power is switched back on, the MV876 will 
backwash the F74C once.
