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 pressure (at least 3 bar) and with a sufficient quantity of
water.
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’ cleaning 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!
Intended Use: this pressure washer has been developed for use in various
professional applications (eg: building technology, cleaning technology,
industrial, transport sector, ...).
REMOTE CONTROL (OPTION)
• The remote control is optional. The burner switch (white) switches on/off the
burner on a distance and has to positions:
• Turn to the right (1): burner on.
• Turn to the left (0): burner off.
• The on/off switch (red) switches on/off the cleaner on a distance and has to
positions:
• Turn to the right (1): machine on, LED on.
• Turn to the left (0): machine off, LED off.
The remote control is not equipped with a cable! The type of cable has to be
the next: 7x0.75 mm² or 7x1.5 mm² and can be maximum 50 m long. This to hold
down the tension drop over the distance.
• 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. In case of disturbance you can reset this by turning on/
off this switch.
