Except for "PREWASH" programs only, the pump P1 is activated automatically during washing.
The neutralising agent for rinsing is automatically dispensed by pump P2 during the phase after washing.
It is important to use good quality detergents to obtain good results. Keep detergent bottles closed in a dry place to
prevent the formation of lumps which might lead to poorer washing results.
Once bottles have been opened they must not be kept for too long, since the detergents tend to lose their efficacy.
ATTENTION
If the jerry can level sensors are not fitted: check the levels of product in the cans / bottles to ensure
that programs are not performed without detergent or neutralising agent.
During installation, or when a completely empty jerry can of product is replaced, run program no. 16
SERVICE to charge the system with liquid. The pipeline from the jerry can to the pump must be filled to
ensure that the product is dispensed properly during subsequent washing cycles.
