- ALWAYS stop the pump prior to touching it for whatever the reason. Wait for the complete pump stopping and make
sure that all the installation control devices are properly set in order to avoid any return flow.
- Pump and piping connected to the pump must NEVER be under pressure when maintenance or repair is carried out.
- NEVER work on the pump when it is hot.
- NEVER touch pump or piping having temperatures higher than 70°C or lower than -10°C.
- ALWAYS be careful when handling pumps that convey acids or hazardous fluids.
- NEVER step on pump and/or piping connected to the pump.
- ALWAYS make sure that the pump is permanently fixed and steady to the installation (i.e. during removal, handling,
installation, etc.)
CAUTION!
Pumps type TCK, TBK and TBAK create a high magnetic field. Personnel should take proper precautions if they
are wearing pace-makers or if they are using instrumentation sensitive to magnetic fields.
The listed below minimum distances must be kept:
- When the magnetic rotor parts are disassembled:
users of pace-maker = 2 meters
floppy disk; magnetic cards, etc. = 1 meter
- When the magnetic rotor is mounted in the pump:
users of pace-maker = 1 meter
floppy disk; magnetic cards, etc. = 0,5 meter
DANGER!
Possible contact with hazardous media and hazardous substances There are certain components in the pump
which may be dangerous to people coming in their contact even during normal operation procedures and/or
maintenance, see table 1.
Take care of their possible disposal according to the laws into force and to a safe local environment
management.
CAUTION!
Danger due to smokes or vapours. In case smokes or vapours are released by the pump do not inhale and
immediately stop the pump for inspection.

3 - IN CASE OF EMERGENCY
In the event of pump break-down and/or loss of pumped fluid, immediately disconnect the electrical power to the motor
(see chapter 11) and contact the responsible personnel in charge of the installation, which should intervene with at least
two people paying particular attention to the fact that the pump may be handling dangerous fluids, hazardous to the health
and environmentally unsafe.
After the causes for the emergency have been addressed and resolved, it will be necessary to follow the starting
procedures (see chapter 10) for the start-up of the pump/motor assembly.
3.1 - BASIC FIRST AID
In the event dangerous substances have been inhaled and/or come in contact with the human body, immediately follow
the instructions given in the company’s internal medical safety procedures.
