1)Material: high quality brass, in high polish and plating finish 2)Surface: polish and with chrome plating. 3)The flushing rate: 5seconds-12" about 4.5L-12L water 4)Choice: customers can choose our wave pipe or S pipe to match this product, and it is applicable for bathroo Flush Valve Installation and Maintenance Manual PRIOR TO INSTALLATION Prior to installing the flush valve, install the items listed below. · Closet/urinal fixture · Drain line · Water supply line Important: · ALL PLUMBING IS TO BE INSTALLED IN ACCORDANCE WITH APPLICABLE CODES AND REGULATIONS. · WATER SUPPLY LINES MUST BE SIZED TO PROVIDE AN ADEQUATE VOLUME OF WATER FOR EACH FIXTURE. · FLUSH ALL WATER LINES PRIOR TO INSTALLING FLUSH VALVE The flush valve is designed to operate with 0.02 to 0.8 MPa of water pressure. THE MINIMUM PRESSURE REQUIRED TO THE VALVE IS DETERMINED BY THE TYPE OF FIXTURE SELECTED. Consult Fixture manufacturer for minimum pressure requirements. Protect the Chrome or Special finish of this flush valve - DO NOT USE TOOTHED TOOLS TO INSTALL OR SERVICE THE VALVE. IMPORTANT: WITH THE EXCEPTION OF CONTROL STOP INLET, DO NOT USE PIPE SEALANT OR PLUMBING GREASE ON ANY VALVE COMPONENT OR COUPLING! TOOLS REQUIRED FOR INSTALLATION · A wrench and a screw INSTALLATION Step 1 - Control Stop Installation Install Control Stop (also called inlet vale) and Supply Flange to the water supply line with the outlet positioned as required Step 2 - Install Flush Connection Hand tighten Spud Coupling onto Fixture Spud, in order to make outlet be further connected with the flush valve. Step 3 - Install Flush valve ADJUSTABLE TAILPIECE The Adjustable Tailpiece compensates for “off-center” roughing-in on the job. Maximum adjustment is 1/2" (13 mm) IN or 1/2" (13 mm) OUT from the standard 4-3/4" (121 mm) (centerline of Flush valve to centerline of Control stop. Insert Adjustable Tailpiece into Control Stop. Wet O-ring seal with water to lubricate. Secure by hand tightening Tailpiece Coupling. Align Flush valve on top of Flush Connection and secure by hand tightening Coupling. Align Flush valve Body and securely tighten Tailpiece Coupling, Outlet Coupling and Spud Coupling, respectively. Step 4 - Install Handle Install Handle Assembly to Valve Body and tighten securely. Step 5 - Flush Out Supply Line Shut off Control Stop and remove Flush valve Cover. Lift out the Inside Parts Assembly. Install Flush valve Cover wrench tight and open Control Stop. Turn on water supply to flush line of any debris or sediment. After completion, shut off Control Stop, remove Flush valve Cover and reinstall Inside Parts Assembly. Install Flush valve Cover wrench tight. Open Control Stop and activate Flush valve. Step 6 - Adjust Control Stop Adjust Control Stop to meet the flow rate required for the proper cleansing of the fixture. Open Control Stop COUNTERCLOCKWISE l/2 turn from the closed position. Activate Flush valve. Adjust Control Stop after each flush until the rate of flow delivered properly cleanses the fixture. CARE AND CLEANING OF CHROME AND SPECIAL FINISHES DO NOT use abrasive or chemical cleaners to clean Flush valves as they may dull the luster and attack the chrome or special decorative finishes. Use ONLY soap and water, then wipe dry with clean cloth or towel. While cleaning the bathroom tile, the Flush valve should be protected from any splattering of cleaner. Acids and cleaning fluids can discolor or remove chrome plating. TROUBLE SHOOTING GUIDE I. Flush valve does not function. A. Control Stop or Main Valve is Closed. Open Control Stop or Main Valve. B. Handle Assembly is worn. Install Handle Repair Kit or replace handle. C. Relief Valve is worn. Replace Inside Parts Kit. II. Insufficient volume of water to adequately siphon fixture. A. Control Stop not open enough. Adjust Control Stop for desired delivery of water. B. Urinal Flush valve Parts inside a Closet Flush valve. Replace Inside Urinal Parts with proper Closet Flush valve Parts. E. Inadequate volume or pressure at supply If no gauges are available to properly measure supply pressure or volume of water at the Flush valve, then remove the Relief Valve from the Inside Parts Kit, reassemble the Flush valve and open the Control Stop. If the fixture siphons, more water volume is required. If fixture does not siphon or if a Low Consumption fixture is installed, or if the above steps do not prove satisfactory, steps must be taken to increase the pressure and/or supply. III. Flush valve closes off immediately. A. Ruptured or damaged Diaphragm. Install Inside Parts Kit to correct problem and update Flush valve. B. Enlarged By-pass orifice from corrosion or damage. Install Inside Parts Kit to correct problem and update Flush valve. IV. Length of flush is too short (Short Flushing). A. Diaphragm Assembly and Guide Assembly are not hand-tight. Screw the two assemblies hand-tight. B. Enlarged By-pass orifice from corrosion or damage. Install NEW Inside Parts Kit to correct problem and update Flush valve. C. Handle Assembly is worn. Install Handle Repair Kit or replace The Handle. V. Length of flush is too long (Long Flushing) or fails to close off. A. Relief Valve is not seating properly or By-pass orifice is clogged because of foreign material, or By-pass orifice is closed by an invisible Gelatinous film from “over-treated” water. -- Disassemble the working parts and wash thoroughly. NOTE: SIZE OF THEORIFICEIN THE BY-PASS IS OF UTMOST IMPORTANCE FOR THE PROPER METERING OF WATER INTO THE UPPER CHAMBER OF THE FLUSH VALVE.DO NOT ENLARGE OR DAMAGE THIS ORIFICE. REPLACE INSIDE KIT IF CLEANING DOES NOTCORRECT PROBLEM. B. Line pressure has dropped and is not sufficient to force Relief Valve to seat. Shut off all control stops until pressure has been restored, then open them again. C. Inside Cover is cracked or damaged. Replace the Inside Cover. VI. Chattering noise in Flush valve. A. The Segment Diaphragm has been installed upside-down. Replace the Segment Diaphragm to the proper position as instructed by Markings on the Diaphragm. B. The Inside Cover has become distorted from wear, freezing or abuse. Replace Inside Cover. VII. Leaking at Handle Assembly. A. The Seal is worn or deteriorated. Install new Seal. NOTE: The Seal will easily slide onto the Bushing if it is wet. B. Handle gasket has been omitted. Install Handle Gasket or Handle Repair Kit. C. Valve Handle Bushing is worn. Install Handle Repair Kit. Refer to the Flush valve Maintenance Guide for additional Trouble shooting and Repair Part information.
