5.0 NOZZLE CONTROLS
ER Bubble Cup nozzles have a twist shut off position controlled by the electric drive.
The twist shutoff is a low-cost alternative to a separate remote controlled valve. Slight fuzzing occurs as debris gradually wears the
valve seat. Over time this may result in minor dripping. The valve seat is simply a nylon washer under the baffl e that’s easily replaced
by removing a screw holding the baffl e (use 3/16” hex key). The seat is a wear-type part that’s not covered under warranty. Order
part #F650 SEAT. If the potential for dripping is unacceptable, then a separate manual shutoff valve with drain at the system’s low
point is suggested.
Electrical controls are connected to the monitor with a 6 pin plug. Refer to LIY-700, Manual: Tactile Touchscreen Controller Users
Guide, for electronic remote operation.
5.1 PATTERN AND FLUSH CONTROL
5.1.1 PATTERN CONTROL
NOTICE
If the nozzle is manually adjusted with the power off , its needs to be reset for accurate electronic
control. Activate the electronic control to the off position for at least 3 seconds to reset.
The ER Bubble Cup nozzles have full pattern control from Off through low fl ow patterns and high fl ow patterns. The nozzle can be
operated manually by turning the SHAPER clockwise (as seen from the operating position behind the nozzle) to move to the straight
stream position. The pattern can be adjusted either by operating the electric actuator or by manually rotating the shaper.
When operating electrically, the shaper will move in slow mode from shutoff to low fl ow straight stream and stop. This is to prevent
unintentional excessive water usage. Pressing the fog button again will move the shaper in slow mode until low fl ow medium fog
is achieved. If the fog button is held past or pressed again after low fl ow medium fog, the shaper will move in fast mode through
straight stream high fl ow and medium fog high fl ow, fi nally stopping at high fl ow, wide fog. Release the fog button at any time to stop
the shaper at the desired fl ow/pattern.
Since the stream trim point varies with the fl ow, the stream should be ‘trimmed’ after changing the fl ow to obtain the straightest and
furthest reaching stream. The nozzle reaction is greatest when the shaper is in the straight-stream position.
To properly trim a stream, fi rst open the pattern to a narrow fog. Then close the stream to parallel to give maximum reach. NOTE:
Moving the shaper further forward will cause stream crossover and reduce the eff ective reach of the nozzle.
