Safety precautions for the operator

The operator is responsible for ensuring the pumps are designed, installed and operated in
accordance with the relevant national provisions. In cooperation with the competent au-
thorities, the operator must mark off all ex-areas and ensure suitable equipment is in use.
This information must then be recorded in the "Explosion Protection Document".
The cable entry and motors are certified for a common operation and they are obliged to
be used just in this combination.
In case of repairing it is just allowed to make use of original spare parts.
2.5

Safety information for inspection and assembly

The operator is responsible for ensuring that inspection and assembly are carried out by au-
thorized and qualified personnel who have studied the operating instructions closely. All ap-
pliances must be disconnected from the mains before any service and repair work. Appli-
ances must not be switched on in the ex-area. Special repairs must only be carried out by our
customer service team or other WILO approved units. In the ex-area, never wipe plastic
parts using cloths or similar materials as this creates a risk of electro-static build-up.
The pump must be switched off for all repair work and secured against unauthor-
ised operation.
In order to avoid infection, maintenance work should only be carried out using
suitable protective gloves.
For reasons of safety, maintenance work should only be carried out in the pres-
ence of another person and never in the ex-area.
2.6

Unauthorised modification and manufacture of spare parts

Alterations to the pump or installation may only be carried out with the manufacturer's con-
sent. The use of original spare parts and accessories authorised by the manufacturer will en-
sure safety. The use of any other parts may invalidate claims invoking the liability of the
manufacturer for any consequences.
2.7 Unauthorised operating methods
The operating safety of the pump or installation supplied can only be guaranteed if it is used
in accordance with paragraph 1 of the operating instructions. All values must neither exceed
nor fall below the limit values given in the catalogue or data sheet as this could lead, for
example, to excess temperature.

Operation in ex-areas

encased three-phase current motor which is impermeable to pressurised water.
