5.3. RESIDUAL RISKS
A residual risk of entering into contact (even if
not accidentally) with the rotor in the suction
port exists due to pump construction.
The residual risk exists in models with thermal
motor protection, that once the trip has activated,
the pump may restart without notice once the
motor has cooled to within the required operating
temperature limits.

Model
DML-DMLV
(see Nameplate)
6.2. USE FOR WHICH PUMPS ARE DESIGNED
Motor-driven pumps are designed to:
- Movement of water as described in paragraph 7.1
- Movement of dirty or sewage water with solids in
suspension as described in paragraph 7.1;
- Emptying cesspits, sceptic tanks, trenches, etc.
6.3. USE FOR WHICH PUMPS ARE NOT DESIGNED
Motor-driven pumps are not designed to:
- pump liquids other than water;
- pump water containing acids or alkalis, and corrosive
liquids in general;
- pump seawater;
- pump flammable liquids and hazardous liquids in
general;
- enter into contact with food products;
- be used in structures designed for living organisms
(pools, aquariums, fish farms, etc.);
- be used in significantly important systems (computer
cooling or refrigeration systems, etc.):
- be used in outdoor environments if equipped with
power cord under 10 m long;
- be used for purposes other than those described in
Chapter 6.2 "Use for which pumps are designed".
The motor-driven pumps must never be made

7.3 INFORMATION ON AIRBORNE NOISE
Given the type of use, the motor-driven pumps do not exceed
an A-weighted sound pressure emission level of 70 dB (A).

8. TRANSPORT, INSTALLATION AND DISMANTLING

On handling and installation work of the pump,
assure safety by confirming the mass and the
shape of the pump referring to the appearance
this instruction manual, drawing, the catalogue,
and other materials.
The handling and installation work of the pump
shall be done only by a qualified technician in
accordance with the applicable legal standards.
