Service
This valve should be serviced by a trained, experi-
enced service technician.
1. If the valve is leaking, drain system OR isolate valve
from the system. Do not remove body from plum-
bing.
2. Check to see if the cartridge needs to be replaced.
3. If the motor or other internal parts of the actuator is
damaged, replace the entire actuator assembly
Note: Honeywell hydronic valves are designed and
tested for silent operation in properly designed
and installed systems. However, water noises
may occur as a result of excessive water
velocity. Piping noises may occur in high tempe-
rature (100°C) systems with insufficient water
pressure.
