It is the responsibility of the installer to utilise tubing suitable for the system; the use of unsuitable tubing can
generate problems with the pump, risks to persons and cause pollution.
The loosening of connections can cause serious safety problems and all such connections should be checked before
and after installation and tightened if necessary.
Never exceed the maximum operating pressure values allowed for the pump and the components to which it is
connected.
Before any maintenance or cleaning operations, close off the air supply and release the pressure from the pump
and the tubing to which it is connected.
Do not subject the pump, the tubing or other parts under pressure to violent impacts; damaged tubing or
connections are dangerous and should be replaced.
After prolonged periods of inactivity, ensure the tightness of all connections subjected to pressure.
It is required that personnel make use of protection devices, clothing and necessary tools, suitable to the place and
employment of the pump both while in operation and during the undertaking of maintenance tasks.
