Maximum Flow Rate: 20 GPM (76 L/min) Accuracy of Outlet Temperature: ±3°F (±2°C)
Notes:
1. Maximum allowable variation in either supply pressure in order to control
the outlet temperature to within ±3°F.
Warning: Pressure variations
outside of this range may cause changes in the outlet temperature.
MAINTENANCE:
The Taco Model 5000-HX Series of mixing valve does not require routine
maintenance but should be checked annually to be sure it is functioning prop-
erly. For installations with poor water quality it may be necessary to inspect
the mixing valve more frequently. Replacement element assemblies are
available.
O-RING/PISTON SUB-ASSEMBLY REPLACEMENT:
1. Isolate the valve from the water supply.
2. Unscrew the union nuts and remove the valve body from the system. For non-union valves remove the valve body from
the piping system.
Removing the valve from the piping system is not required but may make replacement easier
.
3. Using a screwdriver, pry the green cap from the valve.
4. Secure the valve body (using the flats on the body) and unscrew the brass cap to remove the internals of the valve.
5. Remove the piston assembly out of the top of the valve. If necessary, push the piston assembly from the outlet port of
the valve.
6. Using a clean cloth gently wipe out the valve body paying particular attention to the o-ring half way down the inside of
the valve body.
7. Remove the o-ring from the cap. Lightly grease the new cap o-ring and re-grease the o-ring half way down the inside
of the valve with the grease packet provided.
8. Assemble in the reverse order.
9. When re-fitting the brass cap do not over tighten, as this is an o-ring seal.
10. Reinstall the valve into the piping system and set the outlet mix temperature as indicated above in
