Useful advice:
To reduce running costs and speed up the heating process, insulate the pool wherever possible. A floating
solar cover is an essential minimum to retain heat.
4. TROUBLESHOOTING
➢
Quick Function Test
Observe the main electricity meter when the heater is on
(i.e. red light ‘On’) and then observe it again
when the heater is in the standby mode. The test should show that the meter is recording more electricity
being used by the heater when the red light is ‘On’. It is impossible for an electric heater to waste energy,
if it is drawing power then that power will be turned into heat that will be transferred to the water.
➢
Accurate Function Test
If a more accurate test is required to confirm that your heater is delivering the specified heat output, two
electricit
y meter readings will need to be taken from the property’s main electricity meter, at one hourly
intervals (i.e. take one-meter reading and then a second reading exactly one hour later). By subtracting
the first reading from the second reading the number of units (kilo Watts kW) consumed can be calculated.
Note that your heater is also rated in kW hours.
The pool pump and heater will need to be running continuously during the test (i.e. with the heater red light
‘On’. To avoid inaccurate results when performing this test, it is important to refrain from using other high
current consuming appliances in the property, such as tumble dryers, showers, cookers etc. A large
domestic pool pump of one horsepower will draw less than 1-kW in a one-hour period. The conclusion of
the test should prove that for example a 6-kW heater and a half horsepower pump will draw between
6.3-kW to 6.5-kW in one hour.
➢
Heater will not switch from standby to ON (Red light):
In most cases this will be the result of one of the following points not being met:
Possible Cause 1:
The temperature set point has been achieved. To confirm the
increase of the temperature set, turn the dial to a value greater than
the current water temperature.
Possible Cause 2:
Insufficient flow.
Make sure circulation pump is powerful enough to deliver min flow
required to operate the heater (see 3.1 flow requirements).
If using a cartridge filter:
Confirm this by running the system with the cartridge removed from
your pump
and filter unit, this will supply the heater with the maximum
flow rate your unit is capable of. If the heater then switches ‘On’ (i.e.
red light ‘On’) a blocked cartridge can be confirmed to be the cause.
The cartridge should be cleaned or replaced.
If using a sand filter:
Check the pressure indicator on your sand filter and back wash if
necessary.
