Manual

UPSTREAM AND DOWNSTREAM VALVES MUST BE CLOSED BEFORE ATTEMPTING TO REMOVE METER HEAD OR
COVER FROM HOUSING OR PERFORMING ANY SERVICE/MAINTENANCE REQUIRING DISASSEMBLY. FAILURE TO
DO SO CAN LEAD TO HEAD OR COVER BEING "EJECTED" FROM HOUSING, CAUSING PERSONAL INJURY AND/OR
PROPERTY DAMAGE!
1. Loosen each of the head or cover bolts about one and one- half turns. Do not completely remove the bolts.
2. If the O-ring between the meter head/cover and the housing is secure and not leaking, pry the measuring element
assembly loose by inserting a screwdriver blade where the head and housing join together.
BE SURE THAT ANY WATER COMING OUT OF THE METER HEAD DOES NOT SPRAY ONTO ELECTRICAL EQUIPMENT TO
CREATE A SHOCK HAZARD.
3. Allow the meter to drain and relieve internal pressure.
4. When pressure is relieved, remove the head bolts. Lift the measuring element assembly from the housing.
For specific maintenance of the Turbo Head, see the Recordall Turbo Series Meter User Manual.
5. When service is complete, start up the system as noted in “Performance Checks and System Startup” on page 7.
Check Valve
Periodic preventive check valve maintenance is highly recommended and should be practiced according to schedule to
assure continuous accuracy and trouble-free performance of your check valve. The valve is water lubricated and should be
regularly inspected for corrosion, obstructions in the waterways and for freedom of movement for all working parts. The
frequency of the inspections is dependent upon the quality of the water supply and authority having jurisdiction. Make sure
all equipment is adequately protected to prevent freezing and physical damage. Repair all leaks.
To remove or replace the knuckle joint assembly, follow these steps:
1. Shut down the water system and lock it out, if possible.
2. Loosen the vent screw in the lid slowly to relieve system pressure.
3. Loosen and remove all inspection port bolts and remove the lid and gasket from valve.
4. Install proper size clapper check removal tool (see diagram 1 in Figure 3 and Item 10 in Figure 5 ). Be sure tool is pushed
to within 1/2" of linkage.

5. Loosen equally the two knuckle joint mounting bolts until assembly is free. As bolts are loosened, the linkage will
release slightly and lock the clapper retainer tool in place.
6. Remove the knuckle joint from the body assuring the clapper retainer tool is not disturbed, as the preloaded knuckle
joint springs have considerable tension in this position.
7. Bolt the knuckle joint to the outside of the body using the new 3/8" bolts supplied with the new knuckle joint (see
diagram 2).
