P15 - 3-WAY PLANT-WASHING TAP (For the models on which it is foreseen)
The cock (P15) is joined to the tank (P1) and, on one side, to the plant-washing tank (P17) through pipe
(T7), on the other side it is joined to the centrifugal pump (P4) through the suction pipe (T1).
The unit-washing circuit allows to wash the hydraulic circuit (with the exclusion of the tank), in every
moment and independently on the tank load conditions, i.e., also with the mixture present inside the
tank. When the tap (P15) is placed to position “b”the clean water for the unit washing is taken from the
unit-washing tank (P17) by simultaneously excluding the suction from the main tank.
The 3-way cock lever can be positioned as here following specified:
a –
TREATMENT (WORK)
The liquid gets out from the tank (P1) and is sucked by the pump (P4); this is the NORMAL operating
position, which is used in order to carry out the treatment and/or to keep the mixing on. The connection
with washing tank is closed.
b – WASHING PROCESS
The fluid gets out from the unit-washing tank (P17) and is sucked by the pump (P4); that is the position
which is used, in order to carry out the hydraulic circuit WASHING.
TO AVOID THE RETURN OF CLEAN WATER TO THE TANK, WITH CONSEQUENT
DILUTION OF THE MIXTURE CONTAINED IN IT, CLOSE THE FAUCET (P3) AND
COMPLETELY CLOSE THE REGULATOR by rotating the manual regulator handle (P5)
clockwise or by turning the pressure up (keep the joystick on “+” for about 15 seconds
for the versions with pressure regulation electrovalve), DURING THE WASHING.
c – EMPTYING OF THE TANK
In this position, the tank (P1) is emptied. The union with the centrifugal pump is closed. In order
to empty the tank, the drain plug of the union tee (P16) must be removed.
d – COMPLETE DRAINAGE
In this position, it is possible to empty: the tank (P1), the pump (P4) and all the pipes of the hydraulic
circuit. If the plant-washing tank is also filled, it is emptied too.
