Product Usage Instructions
WARNING
Read this Manual BEFORE using this equipment. Failure to read and follow all
safety and use information can result in death, serious personal injury,
property damage, or damage to the equipment. Keep this Manual for future
reference.
WARNING
Local building or plumbing codes may require modifications to the
information provided. You are required to consult the local building and
plumbing codes prior to installation. If the information provided here is not
consistent with local building or plumbing codes, the local codes should be
followed. This product must be installed by a licensed contractor in
accordance with local codes and ordinances.
WARNING
Need for Periodic Inspection/Maintenance: This product must be tested
periodically in compliance with local codes, but at least once per year or
more as service conditions warrant. All products must be retested once
maintenance has been performed. Corrosive water conditions and/or unauthorized
adjustments or repair could render the product ineffective for the service
intended. Regular checking and cleaning of the product’s internal and external
components helps assure maximum life and proper product function.
NOTICE
For Australia and New Zealand, line strainers should be installed between the
upstream shutoff valve and the inlet of the backflow preventer. Fittings such
as end connectors intended to join alternative pipe systems made from other
materials (such as plastics) shall also conform to the relevant dimensional
and performance requirements of the appropriate Australian, New Zealand, or
joint Australian–New Zealand Standard for the alternative pipe system.
Testing
Check the ASSE Series 5000 manual for an appropriate test method that is
consistent with local codes of the area. For Australia, refer to Australian
standard AS/NZS 2845.3. Series 825Y and LF825Y each include a sensor on the
relief valve to detect excessive discharge and trigger notification of a
potential flood event.
NOTICE
An add-on connection kit is required to activate the flood sensor. Without the
connection kit, the flood sensor is a passive component and has no
communication with any other device. (A retrofit sensor connection kit is also
available for existing installations. See “Add-on and Retrofit Sensor
Connection Kits,” for ordering details.)
NOTICE
Use of the flood sensor does not replace the need to comply with all required
instructions, codes, and regulations related to installation, operation, and
maintenance of this product, including the need to provide proper drainage in
the event of a discharge. Watts® is not responsible for the failure of alerts
due to connectivity issues, power outages, or improper installation.
**Installation Guidelines
**
Before installation, consult local building and plumbing codes. Follow the provided installation diagrams for proper setup.
- Consult local codes for specific installation requirements and restrictions applicable to your area. FEBCO recommends that system supply pressure is at least 20 psi (138 kPa).
- Install the assembly in the horizontal position with the relief valve on the side.
- Install the valve assembly where relief valve discharge is acceptable or where it can be completely drained. The valve assembly must be installed where it is accessible for periodic testing and maintenance. Clearances shown in the installation views apply to exterior, interior, and pit/vault installations and are recommendations only. (See Figures 1 and 2). These minimums do not apply to removable protective enclosures. Refer to local codes for actual requirements in your area.
NOTICE
The gap drain is not designed to catch the maximum discharge possible from the
relief valve. The installation of a FEBCO air gap with the drain line
terminating above a floor drain handles any normal discharge or nuisance
spittingthrough the relief valve. However, the floor drain size may need to be
designed to prevent water damage caused by a catastrophic failure condition.
Do not reduce the size of the drain line from the air gap fitting.
- Before installing the valve into the line, flush the supply line of all foreign material. Failure to flush the supply line may cause the check valves to become fouled and require disassembly and cleaning.
- After installation, slowly fill the assembly with water and bleed air from the body using test cocks No. 3 and No. 4. Test the valve assembly to ensure correct operation.
NOTICE
All assemblies are tested at the factory for proper operation and leakage. If
the valve does not pass the field test, its failure is most likely due to a
fouled check valve. This is not covered by the factory warranty. The valve
cover(s) must be removed and the check seats inspected and cleaned. Any damage
or improper operation caused by pipeline debris or improper installation
/start-up is not included in the factory warranty. In case of a possible
warranty claim, contact your local supplier or FEBCO representative. Do not
remove the valve assembly from the pipeline.
- Protect the assembly from freezing and excessive pressure increases. Thermal expansion or water hammer can cause pressure increases. These excessive pressure situations must be eliminated to protect the valve and system from possible damage.
- Use the plastic test cock plugs and tethers provided for areas that require them.
Service and Maintenance
Before following either or both disassembly procedures, close the outlet shutoff valve, then close the inlet shutoff valve. Bleed residual pressure from the assembly by opening test cocks No. 4, No. 3, and No. 2 in this sequence. Also, observe the following points.
- Rinse all parts with clean water before reassembly.
- Do not use any pipe dope, oil, grease, or solvent on any parts unless instructed to do so.
- Do not force parts. Parts should fit together freely. Excess force can cause damage and render the assembly inoperable.
- Carefully inspect seals and seating surfaces for debris or damage.
- After servicing, repressurize the assembly and test to ensure proper operation.
For more information on maintenance, check with your FEBCO representative or go to FEBCOonline.com.
Check Valve Disassembly
-
Unscrew the cover and remove the spring and disc holder assembly.
CAUTION
Practice safety. The covers are spring loaded. -
Inspect the disc and seat area, and clean out any debris. Replace worn or damaged parts as required.
-
Apply FDA Approved grease to the cover O-ring and reassemble the valve in the reverse order of disassembly.
Relief Valve Disassembly
- Detach the activation module, if installed, from the flood sensor.
- Use a #2 Phillips screwdriver to remove the sensor from the relief valve.
- Remove capscrews, diaphragm cover, diaphragm, and port bushing of relief valve and then remove the internal assembly from the body by pulling straight out.
- Inspect for debris, damage, or fouling of the seat disc. Clean and/or replace parts as required.
- Reassemble in the reverse order of disassembly.
- Reattach the flood sensor to the relief valve and mount the activation module to the sensor.
Troubleshooting
If you experience continuous or intermittent relief valve discharge, follow
the troubleshooting guide provided in the manual. Call customer service if you
need assistance with technical details.
