CHECKOUT
IMPORTANT
Operating the system through one complete cycle is
recommended to verify that the valve and actuator
function properly.
Valve
Check Body and Connections for Leaks
Before installing actuator, make sure that the valve stem
operates freely by using the protective cover/manual handle.
Impaired stem operation may indicate that the body was
twisted by faulty piping or that the stem was bent by rough
handling. Either of these conditions may require replacement
of the valve or cartridge insert.
If leaking or other problems occur:
1.
Remove pressure from the valve.
2.
Remove the cartridge insert.
NOTE: Instructions for removing and replacing the
cartridge insert are packed with the WV3000R
Insert Replacement Tool.
3.
Make sure the cartridge insert O-ring is properly seated
and not damaged.
4.
After installing the actuator, check actuator operation.
Actuator
Perform a functional checkout of the M6410A Actuator as
follows:
1.
Change the room temperature setpoint by at least 10°F
(6°C).
2.
Make sure the actuator either opens or closes the valve,
depending on the direction of the temperature change.
3.
If the actuator stem moves in the wrong direction,
reverse the connections for the blue and white actuator
wires.
4.
If step 3 does not resolve the problem, replace the
actuator.
Perform a functional checkout of the M7410F Actuator as
follows:
1.
Change the Y input signal. The movement of the
actuator stem (Fig. 14) indicates if the valve is opening
or closing.
2.
If the direction of the valve stem travel is not correct,
reset the direct/reverse switch.
