Continuous working period
The rating plate states the motor's electrical data as well as the year of manufacture and the serial no. With regard to
maintenance of a specific unit please state serial no. when contacting Landia.
Please note
It is important that the electrical cable is tightened to
prevent the cable from getting into contact with the
propeller. The cable can be ensured against damage
by means of a cable mesh or a chain.
Power connection
Every mixer is equipped with the above mentioned rating plate with technical motor data. It must be ensured that the
other electrical parts correspond to the motor data. For each agitator there is an electrical diagram. A protective motor
switch must be applied at connection of the mixer to the mains.
Only a certified electrician is allowed to connect the unit.
Operation
The mixers have thermal sensors as standard equipment. Often the mixers are exposed to extremely difficult
operation conditions. Therefore, it is important to connect the thermal control. Burning of the motor due to overheating
can thus be avoided. If the safety function has been activated the agitator must not be re-started until the cause of
the disconnection has been found.
Among other things the disconnection can be caused by reduced mains voltage, a propeller blockage or an
overheated motor. The cooling period for overheated motors can be up to 1 hour.
The unit must not operate above liquid level.
