NOTICE
•
We recommend that you use only genuine Delta® replacement parts.
•
DO NOT USE EXCESSIVE FORCE to close the inlet stop stem. We RECOMMEND that the flushometer be flushed while closing the inlet stop. The
noise created by the water flow or the flow into the fixture will stop when the inlet water is shut off.

DÉPANNAGE
Cause
Check that the four "AA" Alkaline batteries are positioned properly in the
battery holder. Use the +/- signs on the batteries and the +/- signs on the
battery holder for correct positioning.
Replace with four new "AA" Alkaline batteries. See
(see Figure 14)" on page 37
Check for damage or corrosion of the battery terminals in the battery
holder. Replace battery holder and batteries if necessary.
Check for power coming from the transformer. Replace if required.
Check power coming from the hardwire converter. Replace if required.
While the TECK® Flushometer will operate up to 125 PSI, the preferred
operating range is between 35 to 65 PSI.
1. Lower the flow rate by reducing the flowing pressure upstream of the
flushometer by adjusting the screw stop. Close the stop completely
and re-open 1 turn. Then adjust the screw to stop the noise.
2. Other options include installing a Pressure Reducing Valve (PRV), or
ball valve upstream to the flushometer.
On flushometers that have been installed for a number of years, check
the renewable seat for wear and replace if necessary.
OPEN inlet stop.
Close the stop completely and re-open 1 turn. Adjust the stop to meet
the required flush volume specification.
WARNING
ONE TURN OPEN may cause EXCESSIVE NOISE. The lowest
open setting for the inlet stop may vary depending on the
installation.
Adjust by slowly turning the regulating screw LEFT (counter-clockwise)
(except on models that have a fixed volume). See
Adjustment (see Figure 9)" on page 14
1. Clean bypass slot.
2. Replace cap/solenoid & regulating screw assembly if required. See
"Cap/Solenoid & Regulating Screw Assembly Maintenance (see
Figure 17)" on page 40
1. Check for damage and alignment of the diaphragm.
2. Replace Diaphragm/Guide Assembly if required. See
Guide Assembly And Seat Maintenance (see Figure 18)" on page
42
for instructions.
1. Check for damage and alignment of the diaphragm.
2. Replace Diaphragm/Guide Assembly if required. See
Guide Assembly And Seat Maintenance (see Figure 18)" on page
42
for instructions.
1. Clean MMO button assembly.
2. Replace MMO button assembly if required. See
Maintenance (see Figure 19)" on page 43
Verify sensing range of the flushometer and adjust if required.
See section
See
"Inadvertent Flushing (see Figure 16)" on page 39
on sensor angle adjustment.
OPEN inlet stop fully.
CHECK supply line for size or obstruction, partially closed gate or other
supply line valve, corroded or under size water piping.
CHECK water pressure and flow rate.
Water supply may be restricted upstream. Open any devices being used
to restrict pressure and/or flow rate to the flushometer (PRV, ball valves,
supply stops).
