2.1 General warnings
The following warnings are intended to help you to eliminate the dangers
that can arise while handling the dosing pump. Risk prevention measures
always apply regardless of any specifi c action.
Safety instructions warning against risks arising from specifi c activities
or situations can be found in the respective sub-chapters.
DANGER
Mortal danger from electric shock!
Wrongly connected or located cables or damaged ones can injure you.
Connect the device only to a socket outlet with earthing contact
protected by a ground fault circuit interrupter (GFCI).
Replace damaged cables without delay.
Do not use extension cables.
Do not bury cables.
Secure cables to avoid being damaged by other equipment.
DANGER
Danger to life through explosions!
When using dosing pumps without ATEX certifi cation in a potentially
explosive area, explosions can occur that result in fatal injuries.
Never use the MEMDOS SMART LK dosing pump in potentially
explosive areas.
WARNING
Caustic burns or other burns through dosing media!
After connecting the mains supply, residual dosing media in the
dosing head can spray out.
Before connecting the mains supply, connect the dosing lines.
Check that all the screw connections have been tightened
correctly and are leak-proof.
WARNING
Caustic burns or other burns through dosing media!
While working on the dosing head, valves and connections, you may
come into contact with dosing media.
Use suffi cient personal protective equipment.
Rinse the dosing pump with a liquid (e.g. water) which does not
pose any risk. Ensure that the liquid is compatible with the dosing
medium.
Release pressure in hydraulic parts.
Never look into open ends of plugged pipelines and valves.
WARNING
Caustic burns or other burns through dosing media!
The materials of the dosing pump and hydraulic parts of the system
must be suitable for the dosing medium that is used. Should this not
be the case, the dosing media may leak.
Make sure that the materials you are using are suitable for the
dosing medium.
Make sure that the lubricants, adhesives, sealants, etc. that you
use are suitable for the dosing medium.
CAUTION
Increased risk of accidents due to insuffi cient qualifi ca-
tion of personnel!
Dosing pumps and their accessories may only be installed, operated
and maintained by personnel with suffi cient qualifi cations. Insuffi cient
qualifi cation will increase the risk of accidents.
Ensure that all action is taken only by personnel with suffi cient and
corresponding qualifi cations.
Prevent access to the system for unauthorised persons.
CAUTION
Danger of personal injury and material damage!
Changing dosing media can lead to unpredictable reactions.
Thoroughly clean the dosing pump and appropriate sections of the
plant to avoid chemical reactions.
