following way:

2 years warranty on motor

3 years on all other parts

Return to base.

Our warranty covers manufacturing faults, not wear and tear.  We will, at our 

discretion, repair or replace the faulty material or part. It is your responsibility to 

notify Theralux  at  the  earliest  possible  time of  any  issues  found  within  the 

warranty period.

Proof  of  purchase  is  required  to  be  presented  with  any  warranty  claim 

submission.

This  warranty  does  not  apply  to  any  misuse  of  the  pool  pump,  negligence  or 

incorrect  installation. We  will  not  cover  any  damage  due  to  the  pool  pump 

running dry, incorrect chemical balance of pool water, flood damage, damage 

caused by running the pump off an extension cord, damage caused by foreign 

material blocking the impeller (pebbles, organic matter, toys, etc.) or if the pool 

pump is used for any other purpose other than a swimming pool.

We will not be liable for any incidental or consequential damages, loss of time, 

inconvenience,  incidental  expenses,  labour  or  material  charges  in  connection 

with the removal or replacement of the equipment, or costs of transporting the

THERAFLO CARE & MAINTENANCE

It is strongly advised that you check the hair and lint pot basket area regularly for 

any debris. If debris is found within the basket, you should empty the basket, as 

a  full  basket  can  result  in  reduced  water  flow  and  an  increased  chance  of 

blocking the impeller.

To do this, please ensure that the power to the pump is turned off before you 

remove the lid. You may also need to re-prime the pool pump once the clean 

basket has been returned. Please follow priming instructions found on start-up 

page 10.

Regularly check the pump for any wet areas or leaks. If you find wet areas around 

the pump, please check and re-tension the 2 connecting unions on the inlet & 

outlet PVC lines.

If by chance you find water accumulating at the base of the motor, this could be 

a  sign  of  seal  damage  and  action  should  be  taken  immediately to  avoid  any 

further damage. It is best to consult your local swimming pool professional if this 

arises.

Please do not run your Theraflo TVS pool pump off an extension lead as this 

results in a drop in voltage current which can damage the motor.

Always ensure that the pump itself is free of flooding.

Always ensure that the pump itself is well ventilated. The pump motor will run 

hot  during  its  normal  operation  and  utilises  the  rear  mounted  fan  to  aid  in 

cooling. It is essential that the rear of the pump is clear of all debris and fixtures 

within 100mm.

Do not under any circumstances run your Theraflo TVS swimming pool pump 

without water as this will damage the internal components. Running the pump 

dry will void any warranty so it is imperative that you maintain adequate water 

levels within your swimming pool at all times. Please also be aware when using 

any small pool toys in the swimming pool that may be small enough to block the 

suction line.
