Description And Use Of Motor-Driven Pump; Specifications - EBARA DL Operating And Maintenance Instructions Manual

5.2. PROTECTION AND SIGNIFICANT CAUTION
All live wires or parts are electrically isolated
from the earth. However, there is an additional
safety feature, which composes of all accessible
conducting parts being connected to an earth wire
so that these parts cannot become hazardous
if the main isolating system fails.
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.

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
