TROUBLESHOOTING
PROBLEM
CAUSE
RECTIFICATION
The desired mixed
water cannot
be obtained, or
temperature is
difficult to set
Hot and cold supplies are fitted
to the wrong connections (cross
connection)
Re-fit the valve with hot / cold supplies fitted to
the correct connections
Thermostatic cartridge contains
debris or is damaged
Clean the cartridge ensuring that all debris is
removed and components are not damaged.
Replace cartridge if necessary
Strainers contain debris
Clean strainers ensuring debris is removed
Water supply pressures are not
within specification
Check that the dynamic pressures of hot and
cold water supplies are between 20kPa - 500
kPa and within 10% of each other
Supply hot / cold water
temperatures are not within
specification
Check supply hot water temperature is set to:
min 55°C - max.85°C, cold 5°C - 25°C
Non-return device is jammed
or faulty.
Check non-return device is not jammed.
Clean or replace if necessary
The valve will not
shut down during
thermal shut down
test
Flow rate is below 4Lpm
Rectify any supply pressure deterioration
Supply hot water temperature
is too low
Check supply hot water temperature is set to:
min 55°C - max.85°C, cold 5°C - 25°C
Thermostatic cartridge contains
debris or is damaged
Clean the cartridge ensuring that all debris is
removed and components are not damaged.
Replace if necessary
Strainers contain debris
Clean strainers ensuring debris is removed
Non-return device is jammed
or faulty
Check non-return device is not jammed.
Clean or replace if necessary
Mixed water
temperature
unstable
Flow rate is below 4Lpm
Rectify any supply pressure deterioration
Thermostatic cartridge contains
debris or is damaged
Clean the cartridge ensuring that all debris is
removed and components are not damaged.
Replace if necessary
Strainers contain debris
Clean strainers ensuring debris is removed
Inlet conditions (pressures or
temperatures) are fluctuating
Install suitable pressure control devices to
ensure inlet conditions are within specification
as stated in Technical Table on page 6.
Non-return device is jammed or
faulty
Check non-return device is not jammed.
Clean or replace if necessary
Mixed water
temperature
changing over time
Inlet conditions (pressures or
temperatures) are fluctuating
Install suitable pressure control devices to
ensure inlet conditions are within specification
as stated in Technical Table on page 6.
Strainers contain debris
Clean strainers ensuring debris is removed
Water is leaking
from mixer body
Mixer body o-rings are worn or
damaged
Replace sealing o-rings
Fitting connections have loosened
Tighten all connections and threads, ensure
they are sealed
