RECOGNITION OF ABNORMAL OPERATION

1. PRESSURE & TEMPERATURE RELIEF VALVE RUNNING

It is not unusual for this to allow a small quantity of water to escape during the heating

cycle. The amount of discharge will depend on hot water usage. As a guide, if it

discharges more than 20 litres of water in 24 hours there may be a problem.

Continuous trickle:

Likely build up of foreign matter. Try gently raising the easing lever on the Pressure &

Temperature relief valve for a few seconds. This may dislodge a small particle of

foreign matter and rectify the fault. Release lever gently.

Steady flow:

Likely causes are excessive water supply pressure, a faulty Pressure & Temperature

relief valve or a faulty thermostat. Turn off the electricity supply and contact your Dux

agent.

2. NO HOT WATER

Is the Pressure & Temperature relief valve discharging too much water? See "Pressure

& Temperature Relief Valve Running".

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 flow

rates with a bucket and a watch. If it is not possible to adjust water usage patterns, an

inexpensive flow control valve can easily be fitted to the shower outlet.

3. HIGH ELECTRICITY BILLS

Is the Pressure & Temperature relief valve discharging too much water? See "Pressure

& Temperature Relief Valve Running".

Is one outlet (such as the shower) using more hot water than you think? See "No Hot

Water".

Is there a leaking hot water pipe or dripping hot water tap? A small leak can waste a

large quantity of hot water.

Replace faulty tap washers and have your plumber rectify any leaking pipework.
