WARNING

Examine all parts for transport damages at receipt. Immediately inform the shipping company in writing of
the found damages.

Examine individual parts for damages in detail. Immediately inform the manufacturer in writing if any
damages have been found.

Vibration generated by pump operation should be absorbed. Take it into consideration when mounting it.

The running pump may generate noise. Its level will depend upon conditions of use (kind of fluid being
pumped, discharge pressure).

Install a cushioned pressure gauge (range up to 0.6 MPa or 1.0 MPa) on the discharge side to measure a
pressure ratio. A vacuum gauge (range: -0.1 to +0.1 MPa) is also recommended in the suction line.

In the event that a cut-off device is located in the discharge line, or there is a possibility that a discharge
line is added, a safety device must be provided (e.g. a pressure switch with differential pressure control,
contact pressure gauge, etc.).

A suction flow stabilizer is advisable in the event that:
- suction line is longer than 3 meters
- suction head is longer than 3 meters

In the event that the medium to be pumped is slightly gas-emitting, a positive head must be created at the
suction side of the pump.

In the event that pumping is carried out to a pressure line or against a pressure control valve, an air valve
must be installed in the discharge line.

DME Series Pumps are not intended to be working in total or partial submersion.

The end of the hose must be equipped with a pit, a protection box, etc. (in case the diaphragm gets
damaged and a leakage of the fluid follows).

Pump exhaust should be directed to a safe place, away from people, animals and food.
