7.1
Max. pressure valve
Max. pressure valve onto the tank plug is maintenance free.
The action of the pressure discharge pin onto the tank plug avoids any clogging of the relief valve
and - at the same time - ensures its proper operation.
7.2
Machine down for up to 7 days
For periods of disuse up to 7 days, proceed as follows:
Horizontal foam markers
•
Fully depressurize the tank as shown in Par. 6.1
•
Slacken the band (
B
) and remove the diffusor (
A
).
Only for horizontal foam markers
(Fig. 14a):
completely slacken the bands and remove the diffuser in the arrow’s
direction.
•
Wash the diffuser (
A
) with water.
•
Remove the grid (
C
) turning it anticlockwise.
•
Extract the sponge (
D
) from the generator (
E
).
•
Carefully wash the foam diffusers and sponge with water.
•
Reassemble the parts taking care when inserting the sponge that must go into its seat
freelyand without compression, as this may compromise foam marker operation.
•
Repeat the above operations for the other foam marker as well.
