•
Italic text
indicates a (sub)title and information that needs
special attention, example:
Read these instructions carefully
•"Monospace text" indicates a message shown in the user
interface, example:

2Introduction
2.1 Functional description
The Empas MCE is primarily intended for weed control on
(semi) hard surfaces. The machine is also suitable for high-
pressure cleaning.
The MCE is based on a three-wheel mobile chassis that carries
the unit. You can move the unit manually.
MCE
The machine can take its water supply directly from a tap water
supply, using a hose. The unit has a standard garden hose
connector for that purpose. A standard garden hose must be
supplied by the user.
A high-pressure pump delivers the water through the water
heating unit to the spray unit. The spray volume is set at 9 liters
per minute with a maximum pressure of 110 bar.
The Hot water unit can heat the water up to 102 °C. The
temperature can be set by the user. The Hot water unit has
three spray heads:
•A pourhead
•A dirt blaster
•A high-pressure nozzle.
17
Weed control
The pourhead is a low-pressure spraying nozzle, especially
intended for spraying a specified area with boiling hot water
(for weed control).
High-pressure cleaning
The high-pressure nozzle and the dirt blaster are high-pressure
nozzles for surface cleaning with hot or cold water. The pressure
is set at 110 bar bar.
