ORDINARY MAINTENACE
Every 2-3 days disassemble and carefully clean manifolds, washing arms and nozzles. If
any nozzle is obstructed, disassemble it wth a screwdriver to remove the obstruction.
Cleaning operations should be carried out with clean water and a non-abrasive brush or
compressed air jets. Do not use pins or unsuitable objects.

EGENERATION CYCLE FOR MODELS WITH WATER SOFTENER
The following procedure describes the regeneration process of the decalcifying resins
contained in the water softener, which has to be performed at regular intervals, depending
on water hardness and the number of washing cycles (see following table).
- Drain the tank. Do not insert the overflow after this operation.
- Open the salt reservoir by unscrewing its cap and fill it with water conditioner salt or com-
mon coarse salt up to 2-3 cm from the upper border (if the reservoir is not filled with water,
fill it before pouring the salt). Then, pour 2 Kg of salt every 10-12 regeneration cycles.
- Clean the reservoir thread of any salt residue before screwing its cap. Remove any salt
residue spilt into the tank.
