Trouble Shooting
THE CLEAR NO / LOW FLOW NEON INDICATOR IS ILLUMINATED:
Possible Cause A:
The flow volume through the heater has fallen below 200-litres
per minute (12m
³
/h) or has stopped completely.
Solution:
Increase the volume of flow through the heater, check for blockages
or if the filter(s) require backwashing.
Possible Cause B:
The heater has been plumbed incorrectly
Solution:
The TITAN heater has a fixed flow direction indicated on the manifold
that houses the flow switch, ensure that the water has been plumbed in the
correct direction through the heater.
THE AMBER OVER TEMP. TRIP NEON INDICATOR IS ILLUMINATED:
Possible Cause:
The ‘thermal safety cut-out’ has tripped.
Solution:
Unscrew the black cover on the water exit side of the heater, press
the red button, if a positive click is felt it is likely that an air pocket has built up
within the heater and needs to be purged to prevent damage to the heating
elements (see diagram below).
IF A POSITIVE CLICK IS NOT FELT:
Cause:
The air temperature within the control enclosure is above 60˚C to reduce the
temperature run the circulation pump for 5 minutes to act as a heat sink to cool the
enclosure - the electrical cabinet thermal cut-out will automatically reset itself when
it has cooled to a safe operating temperature.
N.B
-
The Amber OVER TEMP. TRIP neon indicator will only ever illuminate when
the required temperature is above the current water temperature
