Installation Instructions
1. Consult local codes for specific installation requirements and restrictions applicable to
your area. It is recommended that system supply pressure be at least 20psi (138 kPa).
2. These instructions apply to Series 880V/LF880V sizes 2
1
⁄2" to 10" (65-250mm) only. The
valve may be installed only in the orientation/flow direction as shown. The gate valves
may be rotated as permitted by the flange bolt pattern.
Note: Normal discharge and nuisance spitting are accommodated by use of a FEBCO
air gap fitting and a fabricated indirect waste line. The gap drain is not designed to catch
the maximum discharge possible from the relief valve. The installation of FEBCO air
gap with the drain line terminating above a floor drain will handle any normal discharge
or nuisance spitting through the relief valve. However, 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.
3. 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 only recommendations. These minimums do not apply to
removable protective enclosures. Refer to local codes for actual requirements in your
area.
4. PRIOR TO 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.
5. Lift the assembly by connecting lift hooks to the lift rings cast into the valve body. DO
NOT LIFT THE ASSEMBLY BY CONNECTING TO THE GATE VALVE HANDWHEELS
OR STEMS. The use of the optional valve setters (horizontal units only) provides for a
rigid connection to the supply line (with the correct centerline) without the need for con-
crete thrust blocks.
6. For vertical installation, loosen bolts on the groove coupling just enough to allow rotation
of the outlet check. Rotate the outlet check 180º. Install pipe support (pipe support to be
furnished by customer and shall fit same size pipe as the valve being installed, except
2
1
⁄2" (65mm) valves will use a 3" pipe support).
NOTE: THE VALVE BODY AND PIPE SUPPORT ARE INTENDED TO
SUPPORT THE WEIGHT OF THE SECOND CHECK VALVE AND OUTLET GATE
VALVE ONLY. THE PIPING ABOVE THE OUTLET GATE VALVE MUST BE
880V
SUPPORTED INDEPENDENTLY. Retighten bolts of groove coupling. Rotate outlet gate valve
as desired – required.
6a. For vertical installation of the RPDA, first remove formed tube from bypass piping, and then
follow instructions outlined in No. 6 above. When this has been completed, rotate the com-
pression fitting elbow 180º and reinstall the tube, rotating the pipe tee now at the bottom of
the outlet check to align with tube.
7. After installation SLOWLY fill the assembly with water and bleed air from the body using the #
3 and # 4 test cocks. Test the valve assembly to ensure correct operation.
NOTE: All assemblies are tested at the factory for proper operation and leakage. If the valve does
not pass the field test, it is most likely due to a fouled check valve. This is not covered by the fac-
tory 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.
8. The assembly must be protected from freezing and excessive pressure increases. Pressure
increases can be caused by thermal expansion or water hammer. These excessive pressure
situations must be eliminated to protect the valve and system from possible damage.

Service and Maintenance
General
1. Detailed maintenance manuals are available from your local Febco
representative.
2. Rinse all parts with clean water prior to reassembly.
3. DO NOT USE ANY PIPE DOPE, OIL, GREASE OR SOLVENT ON ANY
PARTS unless instructed to do so.
4. Do not force parts. Parts should fit together freely. Excess force may
cause damage and render the assembly inoperable.
5. Carefully inspect seals and seating surfaces for debris or damage.
6. After servicing, repressurize the assembly and test to ensure proper
operation.
Check Valve Disassembly
1. Close the outlet shutoff valve, then close the inlet shutoff valve. Bleed
residual pressure from the assembly by opening the #4, #3, and # 2
test cocks in this sequence.
