INSTALLATION PROCEDURE
Step 1:
Remove grille (if applicable) and shut off water supply. Actuate sensor to relieve
pressure in the system. Then, disconnect power from plug-in transformer.
Step 2:
Disconnect transformer electrical connector. Discard old transformer.
Step 3:
Connect replacement transformer electrical connectors. Refer to VRKHO7 Wiring
Schematic on page 4 of 4.
Step 4:
Reconnect power to transformer. Turn on water supply and adjust the
bubbler’s flow
using the black regulator mounted next to the solenoid valve. Clockwise adjustment
increases flow and counterclockwise decreases flow. Finally, check fountain for
leaks.
Step 8:
Clear the area in front of the sensor. Allow the sensor to calibrate for at least 10
seconds before operating.
When the sensor is activated continuously for 30 seconds, the sensor will
automatically shut off the water supply to the bubbler. To resume activation, remove
obstruction and reactivate the sensor. This feature prevents flushing of water due to
unintentional activation or vandalism.
Step 9:
Re-install bottom plate and grille (if applicable).
