Care of Chrome Plated Surfaces
The suggested cleaning of chrome plated surfaces is simply to clean them with mild 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 valve
internals to allow the water to drain from the fl ush valve itself.
*See previous page for numerical references.
Corrective Action*
1.) Open stop valve.
2.) Open supply valve.
1.) Open stop valve for desired volume of water.
2.) Replace urinal part with proper closet valve part.
3.) If gauges are not available to measure supply
pressure or volume of water at the valve, completely
remove the working parts and open the stop valve to
allow water to pass through the empty valve. If the
supply is adequate to siphon the fi xture, the guide ring
(#16) may be removed from the guide assembly to
provide additional fl ow (see page 5). Should this prove
unsatisfactory, steps should be taken to increase the
pressure and/or supply.
1.) Install new P6000-EUR or P6000-ECR replacement
kit to remedy the problem. (#12 thru #17)
2.) Install new P6000-EUR or P6000-ECR replacement
kit to remedy the problem. (#12 thru #17) "
"1.) Install the proper P6000-EUR or P6000-ECR
replacement kit to remedy the problem. (#12 thru #17)
2.) Install closet trip mechanism (white #12).
1.) Disassemble parts and rinse thoroughly.
2.) Examine by-pass orifi ce and clean if necessary
being certain not to enlarge orifi ce opening.
3.) Pressure is inadequate or has dropped below
minimum operating range. Steps should be taken to
increase the line pressure.
4.) Replace cover with new one.
1.) Adjust downward on control stop.
2.) Remove the lime build up.
1.) Adjust the control stop for quiet operation keeping in
mind the fi xture evacuation requirements.
2.) Check noise created by fi xture by placing a cover
over the bowl opening to separate valve noise from
bowl noise. If it is deter-mined the fi xture is too noisy
consult with fi xture manufacturer.
3.) High pressure in the system can sometimes be
controlled by the stop valve. Other sources of noise
may be the absence of air chambers and shock
arrestors, loose pipes, improper size pipes, etc. In
these cases the building engineer should be consulted.
1.) Tighten handle assembly.
