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, ...).

Turn off

GENERAL

put the main switch on 0: OFF when you finish the works.

LANCE AND GUN

uncouple the lance and put it away. Close the water supply. Roll up the high
and low pressure hoses.

WATER OUTLET

See chapter "Safety – general warnings"on page 9

PUT AWAY MACHINE

Clean when necessary the water filter. See that the machine is parked frost-
proof. Furthermore, it is recommended to empty the cleaner and accessories
of water, or rinsing with antifreeze. press the wheel clip protections at the front
side (at both wheels - @ ECn-l).

ENVIRONMENTALLY SAFE DISPOSAL OF USED FLUIDS

no fluids (anti-scale product, oil, ...) may be disposed randomly because of the
environment! So make sure, if you are user, that the applicable local guidelines
for environmentally friendly disposal of these fluids (without soil pollution) are
complied.
