6.2 Installation Notes
1. Do not make any electrical connections without adequate grounding.
2. Conduit connections can carry fluids and vapors into the AVA causing damage and voiding the
warranty. Care should be taken when installing conduit to protect against fluid/vapor entry. If
necessary, provide sealed entries or conduit drains near the point of entry.
3. It is recommended that the AVA be powered from a Ground Fault Circuit Interrupter (GFCI) protected
electrical circuit.
6.3 Electrical Wiring
The AVA is available in two voltages, and is rated as follows:
115 VAC, 50/60 Hz, 0.2 A
OR
230 VAC, 50/60 Hz, 0.1 A
Figure 3
Install wiring to the unit using a minimum of 18 inches of flexible conduit or cable attached to the
automatic 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 AVA
voltage and frequency matches that of the power supply. It is recommended that the AVA be powered
from a Ground Fault Circuit Interrupter (GFCI) protected electrical circuit.
1. Remove the enclosure cover from the front of the valve assembly. 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
appropriate wiring diagram, see Section 11. 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 pulls the
valve lever down every 30 seconds.
4. Reattach cover and replace plastic screw hole plugs.
