Danger of Entangling
There is a permanent impending danger of entangling or entrapping hair and clothing in the cooler fan inside the
protection itself near the fan cover casing on the electric motor. Tie long hair up and do not wear baggy clothing, long
laces or other items that could get caught up..
Danger Of Crushing and/or Shearing Caused By Moving Rotor Lobes
Through the openings in the intake and outlet it is possible to access the rotating lobes. Never insert your hands or any
kind of object through the openings. This danger also exists when the machine is not moving, when it is rotated manually.
Danger caused by the pump Seizure
If the use of the pump is NOT compliant with what is indicated in this manual, could cause pump seizure. If you hear an
unusual noise,
that might be lobes’ pump seizure, move away and turn the machine off immediately.
Danger caused by a Noise created by the pump
If the use of the pump is NOT compliant with what is indicated in this manual, during operation the pump could
generate sound emissions exceeding 80dB (A). If this is the case follow the relative instructions given in this manual.
High Temperature danger
If the use of the pump is NOT compliant with what is indicated in this manual, during normal operation, the pump
surfaces could exceed a temperature of 70°C. In this case follow the relative instructions given in this manual.
Moreover, install the pump in a protected area that follows the environmental conditions indicated in point 3.3 and that
can be accessed only by authorized personnel. Do not touch the pump surfaces during its operations and carry out
works only when the pump has stopped and cooled down.
Danger caused by Low Pressure
Avoid contact with pump intake while operating. Use fitting and connecting parts to the system’s piping that can
sufficiently resist the vacuum that arises. Let air into the intake circuit before any intervention. Contact with vacuum
points can result in accidents due to hair and/or clothing being sucked in.
Danger from the emission of Harmful Substances
Whenever air containing hazardous substances is sucked in (for example biological or microbiological agents), use
abatement systems located in front of the pump.
Slip and/or Fall danger
The pumps use oil to lubricate the motion transmission rotating parts and the seal on the shaft. NON conforming use
with respect to the indications of this manual can damage the gaskets of the compartments containing the lubricating
oil that spilling on the floor could cause personnel to slip and/or fall.
Electrical danger
Electrical equipment in the pump includes live parts which, upon contact, can cause serious damage to persons and
property. Any kind of repair work on the electrical system should only be done by specialized personnel and only after
insulating the pump from the mains power supply.
Fire danger
Use of the pump for any unforeseen uses or prohibited by this manual as well as a lack of proper maintenance can
cause malfunction with a risk of overheating and fire. In case of fire, do not use water to extinguish the flames, but use
a dry extinguisher or CO2 or other means compatible with the presence of electrical equipment
Danger caused by the Projection of Parts or Part of them
Arrange the installation of the pump in order to avoid those in charge of works being directly hit by parts or bits of parts
flying through the fan cover casing due to the cooling fan breaking.
