Liquid and Air Circuits

Suction Filter

This is on the bottom left-hand side of the equipment and is easily reachable. To clean the filter you should follow
the steps below.
1. Close the three-way valve
2. Take out the closing valve
is inside.
3. Undo the filter housing
4. Clean the filter and put it all back together again.
Cleaning the filter must be carried out at the end of each treat-
ment, before the remaining liquid solidifies. In this way you will
avoid problems of blockage or lack of suction occurring when
you next use the machine.
Diaphragm pumps
The maximum number of revolutions when in use is 540 rpm. It
is self-priming and can be run dry. Depending on the model ac-
quired, the pump is fitted with 2 or 6 diaphragms. The operating
system is the same for both, but the one with 6 diaphragms pro-
vides more flow.
Be careful to make sure the pump is perfectly greased
when it is to be used.
See "Maintenance" for how frequently the pump has to be
checked.
