PROBLEM SOLVING & MAINTENANCE SUGGESTIONS
We recommend that you use only genuine Delta
®
replacement parts to maintain the warranty.
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.
NO LIGHTS - NO POWER
1. Check that the four “AA” batteries are positioned properly in the battery holder. Use the +/- signs on the batteries and the +/- signs on the battery holder for
correct positioning.
2. If the batteries are positioned correctly, but there are still no lights, replace with four new “AA” Alkaline batteries (“TO REPLACE BATTERIES (see Figure
3. Check for damage or corrosion of the battery terminals in the battery holder. Replace battery holder (060334A, item #3) if necessary.
EXCESSIVE NOISE
1.
PARTIALLY
close the inlet stop.
2. Pressures OVER 75 PSI may lead to an increase in
NOISE
, water could
SPLASH
out of the fixture more easily and the
LIFE
of any plumbing valve may
be
SHORTENED
.
3. Install a Pressure Reducing Valve set at a lower pressure if actual pressure is over 75 PSI. While the TECK Flushometer will operate up to 125 PSI, the
preferred operating range is between 35 and 65 PSI.
4. On flushometers that have been installed for a number of years, check the Renewable Seat (062007A, item #11) for wear and replace if necessary.
EXCESSIVE WATER FLOW RATE
1.
OPEN
inlet stop
ONE TURN
and adjust Regulating Screw (061024A, item #7) to the fixture requirement (except on models that have a fixed volume).
2. Operation of flushometer with inlet stop
BELOW ONE TURN OPEN
may cause
EXCESSIVE NOISE
. The lowest open setting for the inlet stop may vary
depending on the installation.
SHORTAGE OF WATER TO PROPERLY FLUSH BOWL
1.
OPEN
inlet stop fully.
2.
CHECK
pipeline for size or obstruction, partially closed gate or other supply line valve, corroded or under size water piping.
3.
CHECK
water pressure.
4. Water flow rate is determined by
BOTH
the water pipe size
AND
the water pressure available.
5. A water closet flush valve requires a minimum water supply of 1” (or larger), depending on a number of different factors including water pressure (PSI)
available, pipe size and length of pipe run, number of fixtures per washroom and per building, fixture type, fixture usage factor, elevation of valve above the
water main, etc. We strongly recommend that pipe size calculations be done to insure proper water supply sizes.
Flushometers
DO NOT
provide a water supply; they are merely automatically timed self-closing valves. The inlet supply piping is the water reservoir that
must supply sufficient water volume in a short period of time (4 to 10 seconds) to properly flush and clear the fixture.
CONTINUOUS FLUSHING
1. The Regulating Screw (061024A, item #7) may be turned
RIGHT
(clockwise)
TOO FAR
. Adjust by slowly turning the Regulating Screw
LEFT
(counter-
clockwise) (except -48, -42, -19 and -05 models, which are fixed volume).
2. If flush is still continuous, close inlet stop, remove Regulating Screw (061024A, item #7),
CLEAN
bypass slot in the Screw,
REPLACE
it in the valve and
ADJUST
slowly for proper flush (except on models that have a fixed volume).
3. Remove cap assembly (item #8) and Diaphragm/Guide Assembly (061323A - W/C, item #10a or 061324A - UR, item #10b), check for contaminants at
renewable seat (062007A, item #11) and diaphragm and check for debris in the cap for blockage. Also
CHECK
that the Diaphragm/Guide slides easily in
the Renewable Seat.
4. If sensor is picking up a reflective surface, or flushes when someone walks by, range too long; shorten range or adjust sensor angle (“Sensor Angle
Adjustment / Réglage de l’angle du capteur” on page 10).
VALVE WILL NOT FLUSH
1. When the valve has been taken apart for servicing and re-assembled and
DOES NOT
operate, check that the Cap has been put on the body properly. The
Regulating Screw (061024A, item #7) should always be on the same side as the inlet stop.
2. When all lights operate as expected but valve will not flush, check that the solenoid wires are connected and the solenoid is making a clicking sound. If no
clicking sound is present, then replace with cap/solenoid & regulating screw assembly (item #8).
3. If the valve will flush but shuts off immediately when activated, the Diaphragm (060079A-MMO, item #10c) may be worn or split and need to be replaced.
4. The flushometer may not detect a user if the toilet seat is left in an upright position. This can be due to the Flushometer being installed too low or there is
no gap in the front toilet seat. Adjust the height of the valve or change the toilet seat.
5. The sensor may have trouble detecting certain types of clothing material.
SLIGHT WATER LEAK INTO FIXTURE
1.
EXAMINE
the seating surface of the Diaphragm (060079A-MMO, item #10c) for embedded sediment.
