Pumps Ht; Mist Sprinkler Function (Option) - Dibo ECN Mode D'emploi

4.5. Pumps HT

There must be present a pre- pressure (pump) at HT pumps (pumps with high temperature).
The pre- pressure (pump) must provide for sufficient flow of water to feed the high pressure pump and to occur
cavitation. Cavitation is the phenomenon that in a moving fluid the local pressure is going to be lower than the
vapour pressure of the fluid.
Because of this mist bells will arise who can implode with high power in the pump and could cause damages.
For all these applications at high temperature, it is ABSOLUTELY ESSENTIAL to feed the pump with positive pres-
sure (at least 3 bar) and with a sufficient quantity of water.

4.6. Mist sprinkler function (option)

At the mist sprinkler function a command is given to the ECN cleaner and it's rinsed there during 1 minute.
Afterwards the cleaner will stop 20 minutes.
Next there will be rinsed again during 1 minute. This cycle is repeated.
At the ECN with mist sprinkler function you need a mist sprinkling tripod (see pic. below at right).
This function can be set active by turning the black switch at the control panel (see photo).
The time to rinse - stationary position can be adjusted.
This happen by adjusting the time relay (see photo).
Ton = stationary time - blue button: calibration, white button: regulation (begin- and end values of calibration).
Toff = rinsing time - blue button: calibration, white button: regulation (begin- and end values of calibration).
Example photo:
- Toff calibration: position 1 at regulation 1-10 min, then the regulation time shall be 1 minute, at position 10 this will
be 10 minutes.
- Ton calibration: position 3.5 at regulation 6-60 min, then the regulation time shall be approx. 20 minutes, at posi-
tion 10 this will be 60 minutes.
