Troubleshooting
Water Discharge From The PTR
Valve
Pressure & Temperature Relief Valve
(PTR)
It is normal for the PTR to allow a small
quantity of water to escape during the
heating cycle. The amount of discharge
will depend on hot water usage.
Continuous trickle (PTR)
This is most likely due to a build up of
foreign matter. In this case try gently
raising the easing lever on the Pressure
& Temperature Relief Valve for a few
seconds then release gently. This may
dislodge a small particle of foreign
matter and rectify the fault.
Steady ow (PTR) – more than
20L per day
This may be caused by excessive water
supply pressure, a faulty Pressure &
Temperature Relief Valve or a faulty
thermostat. Turn off the electricity supply
and contact your Dux agent.
No Hot Water
Is the Pressure & Temperature Relief •
Valve discharging too much water?
Do you have the correct size water •
heater for your requirements? Sizing
details are available from your Dux
supplier.
Is one outlet (such as the shower) •
using more hot water than you
think?
Carefully review the family's hot •
water usage and if necessary
check the shower ow rates with a
bucket, measuring the amount of
water used over that period of time.
If it is not possible to adjust water
usage patterns, an inexpensive ow
control valve can easily be tted to
the shower outlet.
Consider that during night time •
heating, the time taken to heat the
tank can take longer (less energy
in the air) so you may nd that the
tank has not fully recovered from a
period of heavy usage the previous
evening.
