1.3. Responsibilities of the management and maintenance personnel
The management must ensure that:
- the maintenance personnel observe the safety instructions, as described in this
document;
- any equipment necessary for working according to the safety instructions is made
available;
- the maintenance personnel possess the necessary skills.
Maintenance personnel should follow these safety instructions when carrying out
installation, repair and maintenance.
1.4. Applying the safety instructions when installing a valve
After removing the packaging material it is possible to reach the inlet and outlet of the
valve. During this operation do not turn the rotor by hand.
Do not alter, remove or paint the type specification plates of the valve, drive unit or
fitted switches.
1.5. Applying the safety instructions when the valve is in operation
Only operate the valve when it is fitted with the protective safety parts supplied by
DMN. These are:
- mechanical protection e.g. chain guard and end cover plates;
- electro-mechanical protection e.g. safety switches (if fitted).
While the valve is in operation no maintenance or repair work must
be carried out.
1.6. Applying the safety instructions during maintenance and repair work
When product qualities necessitate supplementary safety instructions and wearing of
protective equipment, it is obligatory to follow the local safety instructions.
Before maintenance and repair work is carried out:
- electrical supply to the valve motor must be isolated.
- air pressure to shaft seals must be isolated (if fitted).
After the maintenance and repair work has been carried out, all safety parts removed
during the work should be re-assembled and their operation should be checked.
