MAINTENANCE
DeltaPoint water savers require no maintenance. If the flow tubes become clogged with debris, the unit
should be removed for service and cleaning. Significant clogging may result in erratic operation, errors
or faults. Do not place tools into the tubes, as this may permanently damage the vortex sensor. The
vortex sensor
cannot
be repaired.
To clean the flow tubes, remove the shut-off valve and check valve. Run clean water into the
downstream end of each leg. Large objects jammed against the bluff body may be dislodged by lightly
tapping the upstream end of the flow tube against a firm surface.
CAUTION: Do not tap the flow tube
too hard or damage may occur.
Shut-Off Valve
The manufacturer recommends that the diaphragm be removed and cleaned periodically. The
operation of the valve is based on small orifices functioning properly. Depending on the level of water
contamination, cleaning frequency could vary from monthly to yearly. If a low-maintenance type valve
is required and air is available, please contact factory and request information on the air-operated shut-
off valve.
Check Valve
If check valve is leaking, it may be disassembled and cleaned.
See
APPENDIX
for information on this valve.
Cleaning
These meters do not require any special cleaning of the external surfaces. If cleaning is deemed
necessary, strong solvents, detergents, or chemicals should not be used. A damp cloth may be used to
wipe off dirt or debris.
Note
If used outside the parameters specified in this manual, the proper operation of the flowmeter cannot
be guaranteed.
