1.7.2.
Electrical safety
Do not carry out any maintenance or/and operation on the pump while it is running or
before it has been disconnected from the power supply. Avoid any danger caused by
electric power (for details see current regulations in force). Check that electrical
specifications on the data plate are equivalent to the power supply to which it will be
connected.
1.7.3.
Chemical hazard
Whenever the pump is to be used for pumping a different liquid, it is essential to clean the
pump beforehand in order to avoid any possible reaction between the two products.
1.7.4.
Dry running
Do not start nor carry out running tests before filling the pump with liquid. Always avoid dry
operation of the pump. Start the pump when it is completely filled and with the valve on the
discharge side opened.
1.7.5.
Noise level
CT pumps, including the motor, in normal operating conditions produce a sound level
below 80 dB(A). The major sources of noise are: liquid turbulence in the
installation
,
cavitation or any other abnormal operation that is independent from the pump construction
nor the pump manufacturer. The user must provide suitable protective means if the
sources of noise could produce a harmful noise level for operators and for the environment
(in compliance with current local regulations).
1.7.6.
Temperature hazards
Raised temperature can cause damage on the pump and/or piping and may also be
hazardous for personnel in the vicinity of the pump/piping. The hot or cold parts of the
machine must be protected to avoid accidental contacts
1.7.7.
Rotating parts
Do not tamper with the protection of the rotating parts, do not touch or approach rotating
parts in movement.
1.7.8.
Cleaning and disinfection
Cleaning and disinfection of the pump system is of greatest importance when the pump is
used in a food process installation. Use of a pump system that is NOT cleaned or
disinfected can cause contamination of the product.
