2.3 Intended use
- The Alfa Laval Agitator is only for mixing/stirring of liquids in a tank.
- The Agitator is only for mounting positions as specified on the nameplate by the first group of letters of the type designation.
ALT(B)- is for top mounting, ALS- is for side mounting and ALB- is for bottom mounting.
The exact mounting angle is specified on the Name Plate and must be followed. Definitions on mounting angles can be seen in
section 6.2 Mounting angle for top mounting agitator type ALT.
- The different duties and operation data like pressure, speed and media temperature, which the Agitator is designed for, can
be found in the Alfa Laval quotation agreement1) and may not be exceeded by all means.
- If the Agitator is installed in pressurized tanks local regulations and legislations must be met.
1) The Alfa Laval quotation agreement has been exchanged during the quote process between a technical purchaser and Alfa Laval. If you are
not in hold of the Alfa Laval quotation agreement, please get through to your local Alfa Laval contact, inform the Agitator serial number and
article number which is stated on the Name Plate and you will obtain the Alfa Laval quotation agreement.

Installation:
Always read the technical data thoroughly (see chapter 6 Technical Data).
Always follow installation instructions thoroughly (see chapter 3 Installation).
Never expose the Agitator to undue vibrations or shocks.
Never start Agitator in the wrong rotation direction.
Ensure that the tank media is not corrosive to the Agitator.
Only install the Agitator in environments within temperature limit: -20°C and +40°C.
Only install the Agitator in altitudeslessthan1000mabovesealevel.
!
Never touch the moving parts while the Agitator is connected to the power supply.
Operation:
Always read the technical data thoroughly (see chapter 6 Technical Data).
Always read supplier instructions thoroughly (see chapter 8 Appendix).
Never start Agitator in the wrong rotation direction.
Always rinse well with clean water after cleaning.
Beware of temperature limitations.
Beware of Agitator in operation can produce sound levels in excess of 85dB(A).
Never operate continuously within 20% of critical oscillation speed (see chapter 6 Technical Data).
!
Never touch the moving parts while the Agitator is connected to the power supply.
Maintenance:
Always read the technical data thoroughly (see chapter 6 Technical Data).
Always follow the maintenance instruction thoroughly (see chapter 5 Maintenance).
Always follow the maintenance instruction from drive unit supplier (see chapter 8 Appendix).
Always study the parts list and assembly drawing carefully (see chapter 7 Part lists, part drawings and service kits).
!
