Diagnostics (cont’d…)
An alternative method is to set the temperature control several degrees above normal
and use the main supply meter to check how many Units (kWh) the heater consumes in
an hour. This figure should be slightly above the kW rating of the heater, allowing for the
filter pump and other domestic equipment on the same supply.
If the power consumption is less than the rating of the heater then the issue is elsewhere
in the system, for example:
Low voltage supplied to the heater, indicating that cable diameter is too small or
run is too long;
Inadequate mixing of the warm water from the heater with the cooler water in
the pool, leading to a layer of warmer water forming at the height of the inlets.
To cure this, aim the direction of the pool inlet jet downwards;
Incorrect setting of any time witches fitted to heater or filter pump;
The time switches are not synchronised with the main off=peak electrical supply
meter;
Lack of water flow caused by insufficient pump head, or blockages in the
pipework.
Warranty
The heater is guaranteed for two years against faulty workmanship or materials. This
does not cover damage caused by incorrect commissioning & maintenance or by other
neglect of the heater. In the event of a claim, Thermalec will at it sole discretion replace
the heater, provide replacement parts or effect a repair at its factory or its local
distributor.
