• If the cable must be extended do as follows:
- handle the joint carefully and avoid submerging it;
- do not extend the cable more than the necessary length choosing a suitable dimension
of the cable.
A voltage drop may occur if the cable is too long or if the dimension is too small, so as
to give you problems to start the motor.
• The installation depth has a great importance for the conditions of the motor. The more
the quantity of water increases the more the motor has to work. For safety reasons do not
exceed the following depths:
- Verify that the aerator is not in use until the motor is completely submerged by the
liquid to be aerated, otherwise a superheating of the motor will occur.
- You are advised to install the aerator in square or round tanks; if they are rectangular
it will be better to use lower power aerators. Alternatively we suggest using SC aerators
together with SC mixers in order to avoid the stagnation of the liquid to be aerated into
the basins.
- After a period of inactivity, check that the aerator contains the right quantity of oil.
When it is not the first installation, also check that there are no impurities and/or water
(consult the “Maintenance” chapter).
Before connecting the aerator to the electrical power, verify by hand that the impeller
has free rotation.
ATTENTION: Do never ever carry out this operation when the aerator is electrically
connected and before having checked the free rotation of the impeller
when the motor is put on a suitable floor.
(SEE TABLE WITH WEIGHTS
TABLE ON PAGE 25/26).
Specialised and authorised staff will carry out the electrical connections
of the power cable to the control panels, which is equipped with all the
suitable thermal and electrical protections. The very same spacialised
staff will verify that the rotation sense is clockwise.
