OPERATING INSTRUCTIONS
Figure 6
A. FLOWING WATER
Once the oscillating flange is centered on the desired target, it is ready for operation. A minimum operating pressure of 50 psi is required. The speed
of oscillation is dependent on the pressure, flow through the nozzle, and the oscillation angle. The speed of oscillation can be adjusted with the SPEED
CONTROL knob. The SPEED CONTROL knob will stop the oscillation if it is fully closed.
NOTE: The unit will discharge water from the water turbine housing during use.
B. TESTING THE OSCILLATION RANGE
The oscillation angle can be tested using a hose supplied from an appropriate water source. The TEST PORT is a female ¾" GHT (garden hose thread)
swivel which can be connected to a hose.
1. The SPEED CONTROL knob must be fully closed.
2. Attach the garden hose to the TEST PORT.
3. Apply pressure to the garden hose.
4. If the oscillation needs to be stopped during the test, open the SPEED CONTROL knob or shut off
the main water supply.
C. COLD WEATHER
The water jet which drives the water motor has been designed to self-drain to withstand freezing temperatures as long as the water level in the main
water way is below the bottom of the oscillating flange.
CAUTION: It is recommended that either an automatic drain valve is installed below the oscillating flange or the water is drained from all plumbing.
CAUTIONS:
Your oscillating flange, monitor, and nozzle should be inspected prior to and after each use to ensure it is in good operating condition. Periodically, an
unanticipated incident occurs where the unit is used in a manner that is inconsistent with standard operating practices. A partial list of potential misuses
includes:
• Operating above maximum rated pressure or flow.
• Improper draining and allowing water to freeze in the unit.
• Prolonged exposure to temperatures above 140 degrees F, or below -40 degrees F.
• Operating in a corrosive environment.
• Other misuse that may be unique to your specific environment.
Also, there are many "tell tale" signs that indicate repair is in order, such as:
• Jerky or hesitant oscillation motion.
• Excessive wear.
• Poor discharge performance.
• Water leaks.
If any of the above situations are encountered, the oscillating flange should be taken out of service, inspected, repaired and tested by a qualified techni-
cian before placing it back in service.
ROUTINE MAINTENANCE INSTRUCTIONS
The following maintenance procedures will extend the service life of this appliance.
WARNING: Maintenance should not be performed while flowing water. Disconnect from water supply
prior to maintenance.
A. Use the test port to operate the oscillating flange or flow water through the main waterway once
every six months.
B. The gearbox lubrication should not need changed during the lifetime of the device.
C. The flange bearings are an engineered polymer that is self-lubricating and does not require maintenance.
D. Check for leaks, excessive wear, looseness of the flange joint, loose bolts in the oscillation mechanism every
six months or after each use whichever is shorter.
