Ht Pumps; Scope Of Application; Disturbances Ibh-M/L - Dibo IBH 1.780.020 Gebrauchsanweisung

Settings (remote control 2)
- Machine off (main switch off) = LED on/off switch does not glow.
- Machine on & functioning ok (main switch on) = LED on/off switch lights continuously irrespective if the on/off
switch will be switched on/off.
- Machine in failure = LED on/off switch flashes, flash frequence depending type off disturbance (see 4.6).
In case of disturbance you can reset this by turning on/off this switch.

4.4. HT pumps

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 pres-
sure 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 pressure (at least 3 bar) and with a sufficient quantity of water.

4.5. Scope of application

Efficient high pressure cleaning is achieved by following a few guidelines combined with your own experiences.
Each cleaning job is different and specific, therefore contact DiBO for the best solution in your application sector.
Using cleaning products (if applicable): the surface to clean should be sprayed so the product can act during
some time (do not let it dry!) before cleaning with high pressure jet.
Cleaning agents can increase the cleaning effect if they are used correctly!
Always follow/consider the safety instructions of the used product!
Cold water (high pressure) cleaning: removal of (mild) impurities/pollution and rinsing.
Hot water (high pressure) cleaning (if applicable): the cleaning effect will be such improved through increasing the
temperature (set the temperature experimentally according to the application).
Cleaning via lance with rotating head (if applicable): cleaning method to remove tough layers of dirt.
Cleaning using a steam lance (if applicable): this steam function (by overheating water) is used in 'sensitive' clean-
ing applications (eg: damage sensitive surfaces) where there is stubborn dirt (eg: degreaser) is removed by using
steam.
Please note: this application has high cleaning temperatures and requires various safety measures!
