Set To Work; Pumps Ht; Scope Of Application - Dibo PTL-S Bedienungsanleitung

4.7. Set to work

Put the high pressure cleaner as much as possible in a horizontal position.
Connect the spray gun with the high pressure hose (without spray lance) to the high pressure cleaner.
Turn the main switch to position ON.
Starts the engine with key (electrically) or with the pull rope (by hand) until the engine starts.
Aim the spray gun in to the free space and operate the spray gun until the water jet is completely deaerated (+-
30 sec.). Turn the main switch to position OFF.
Connect the spray lance to the spray gun.
Operate the spray gun and check the working pressure on the pressure gauge.
Adjust if necessary the pressure regulator for the right spray pressure.

4.8. 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.

4.9. 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!
