3.3. Fitting the air hose
3.4. Fitting the pressure switch.
A.- The hose (18) must be attached to the wall to form an air trap, or at a level above the maximum height of the
swimming pool, so as to avoid emptying the pool. Use a securing staple to ensure correct fitting. Mount the filter
(22) on the end of the hose in order to prevent dirt entering.
The maximum length to ensure correct operation of the pressure switch is 8 metres. It is advisable to cut the
capillary pipe to just the right length to reach the panel, ensuring that the connecting pipe is passed through
again.
(when there is not air regulator)
1- Connect the capillary pipe (24) at the ends of the capillary pipe (17) and then connect it to the presure
switch,ensuring that is firmly connected.
