Install Instructions
MAINTENANCE MANUAL
General
1.   Detailed maintenance manuals are available from your local FEBCO rep-
resentative.
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.  Remove cover-bolts using the appropriate size wrench.
2.   Remove the spacer between the checks by grasping the flanged end of 
spacer and pulling straight up.
3.   Remove the inlet check assembly by pulling it out from the body bore, 
in the direction of flow, until it is completely exposed, then lift out of 
body.
4.   Remove the outlet check assembly by placing the tip of a medium 
sized flat nose screw driver in the slot of the seat and prying the check 
assembly back until the O-ring is exposed. Then, using your fingers, pull 
it out from the body bore until it is completely exposed. Lift it from the 
body.
5.   Both check assemblies are disassembled and reassembled in the same 
manner. To disassemble, grasp the seat section in one hand and the 
guide section in the other hand. Rotate in a counter-clockwise direction 
(approximately 
1
⁄8 turn) until the two parts disengage.
6.   Inspect for debris, damage or fouling of the seat disc. Clean and/or 
replace parts as required.
7.  Reassemble the valve in the reverse order of disassembly. 
Service and Maintenance
Relief 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.
2.   Remove the relief valve cover bolts, cover and relief valve assembly in 
accordance with the FEBCO maintenance manual.
3.   Inspect/clean seat surfaces, seals and diaphragm. Replace worn or 
damaged parts as required.
4.  Reassemble the relief valve in the reverse order of disassembly.
Test Procedures
FEBCO recommends the use of the appropriate test method presented in 
the ASSE Series 5000 manual that is consistent with your local codes.
