Care of Chrome plated surfaces.
The suggested cleaning of chrome plated surfaces is simply to clean them with soap and water then dry. Commercial cleaning compounds are never
recommended.
Seasonal use.
Valves used in installations subject to shut down because of cold and freezing conditions should be maintained in the following manner. After the main
supply has been shut off and the water drained from the system,remove the stop valve cap and stop internals to allow the water to drain from the
flush valve itself.
Problem
Valve will not operate.
Cause* Corrective Action*
ZEM S-ISAQUAVANTAGE TROUBLE SHOOTING
1.)Stop valve is closed
2.)Supply valve is closed.
1.)Open Stop valve.
2.) Open supply valve.
1.)Stop valve not open enough.
2.)Urinal trip mechanism installed in closet kit. Urinal
kit installed in closet valve,or 1.0gal. urinal kit
installed in place of 1.5gal urinal kit.
3.) Insufficient volume or pressure at supply.
Insufficient volume of water to
adequately flushfixture.
1.)Open stop valve for desired volume of water.
2.)Install appropriate parts or kit.
3.)If gauges are not available to measure supply pres-
sure or volume of water at the valve,completely
remove the working parts and open the stop valve to
allow water to pass throughthe empty valve. If the
water supply proves unsatisfactory,steps should
be taken to increase the pressure and/or supply.
Flushvalve shuts off too quick. 1.)Damaged or punctured diaphragm.
2.)Enlarged by-pass orifice.
1.)Install new replacement kit to remedy the
problem.
2.)Install new replacement kit to remedy the
problem.
3.)Screw the two assemblies hand tight.
4.)Install new Z6000-ECA,Z6000-EUA replace-
ment kit to remedy the problem.
5.)Install closet trip mechanism (white).
3.)Cylinder guide assembly and diaphragm assembly are
not tight.
4. )Enlarged by-pass orifice.
5.)Urinal trip mechanism (black)in closet flushvalves.
Valve is flushing too long or not
shutting off.
1.)Trip mechanism not seating properly due to foreign
material between trip mechanism and retainer disc.
2.)By-pass orifice is plugged or partially plugged.
3.)Line pressure is not adequate to force trip mechanism
to seal.
4.)Cracked cover.
1.)Disassemble parts and rinse thoroughly.
2.)Examine by-pass orifice and clean if necessary being
certain not to enlarge orifice opening.
3.)Pressure is inadequate or has dropped below mini-
mum operating range. Steps should be taken to in-
crease the line pressure.
4.)Replace cover withnew one.
Water splashes out of fixture. 1.)Supply volume is more than is necessary.
2.)Lime accumulation on vortexor spreader holes of
fixture.
1.)Adjust downward on control stop.
2.)Remove the lime build up within the fixture.
Flushis not considered quiet. 1.)Control stop may not be adjusted for quiet
operation
2.)Fixture may be contributing to noise
3.)Piping system may be source of noise.
1.)Adjust the control stop for quiet operation keeping
in mind the fixture evacuation requirements.
2.)Checknoise created by fixture by placing a cover
over the bowl opening to separate valve noise from
bowl noise. If it is determined the fixture is too
noisy consult withfixture manufacturer.
3.)Highpressure in the system can sometimes be con-
trolled by the stop valve. Other sources of noise
may be the absence of air chambers and shockar-
restor,loose pipes,improper size pipes,etc. In
these cases the building engineer should be con-
sulted.
1.)Lens may be dirty.
2.)Power supply output is out of tolerance.
3.)Sensor is viewing stall door.
1.)Clean lens.
2.)DC voltage must be between 7.4-9volts. Check
for power fault or malfunction in a unit or replace
witha Zurn power converter.
3.)Re-calibrate sensor per step 11.
Sensor assembly leaking 1.)Sensor assembly is not tight. 1.)Tighten sensor assembly.
1.)Sensor does not recognize a user.
2.)Power supply may be disrupted.
1.)Re-calibrate sensor per step 11.
2.)Checkavailable voltage where escutcheon is
attached to wall withDC voltmeter. 7.4-9VDC is
required.
Flushvalve does not activate
after user leaves.
Flushvalve "ghost" flushes or
activates randomly withno user
present.
Valve activates repeatedly when
power is provided.
1.)Insufficient DC power level (less then 7.4volts DC) 1.)Upgrade the -HW 6 power supply to the new
ZURN power supply (greater than 7.4volts DC)or
replace the PC6 supply.
