Install wiring to the unit using a minimum of 18 inches of flexible conduit or cable attached to the

auto valve assembly in order to facilitate removal of the valve assembly from the reagent head for

cleaning or maintenance.

Wiring must conform to all applicable codes. Prior to pump startup; always check to ensure that the ADV

voltage and frequency matches that of the power supply. It is recommended that the ADV be powered

from a Ground Fault Circuit Interrupter (GFCI) protected electrical circuit.

1. Remove the enclosure front cover. Note: The plastic screw hole plugs can be pried out using a flat

bladed tool.

2. Bring AC power and ground wires into valve assembly enclosure through the 7/8” diameter hole in the

side of the enclosure. Use #18 AWG 105 degree C insulation wire size minimum. Connect per the

wiring diagram. The wiring diagram is also reproduced on a label affixed to the back of the enclosure

cover.

3. Apply power to the valve assembly with or without the pump running. Verify that the solenoid

mounted on the pump reagent head clicks every 30 seconds.
