How to thaw & reset the pump freeze protection circuit on your EMV carpet extraction machine.

Well it’s that time of year again where technicians are taking they're portable extraction machines out of there van to find they have a frozen pump. With a pump head frozen the pump motor will stall resulting in it trying to compensate by drawing as much amperage out of the socket as it can achieve.

If you are unlucky and the fuse doesn’t blow, it is very likely that your pump will be permanently damaged with the motor winding failing. This is not the case with an EMV machine as it is fitted with an industry first system curing this potential problem.

In the event that your EMV machine pump is frozen we have designed an automatic inbuilt pump freeze protection circuit. The EMV pump freeze protection circuit will monitor your pump and ensure that the pump is disabled before any damage can occur. Once you have thawed your pump out you can reset this circuit and start working.

Instructions on how to reset your frozen pump can be found on page 7 of your EMV manual.

In the event that you have not got your manual to hand, we have made a video showing how simple it is to thaw out and reset the freeze protection circuit on your EMV machine.
