The mixer is deactivated during decommissioning, but remains installed. This ensures
that the mixer is always ready for operation.
‡
To protect the mixer from frost and ice, always immerse the mixer completely in
the fluid.
‡
The fluid temperature must always be above +3 °C (+37 °F).
1. Switch off the mixer at the operating point.
2. Secure the operating point against being switched on again by unauthorised per-
sons (e.g. lock main switch).
▶ The mixer is decommissioned and can now be dismantled.
If the mixer remains installed after decommissioning, observe the following:
▪ Ensure that the aforementioned requirements are maintained for the complete period
of decommissioning. If these requirements cannot be guaranteed, dismantle the mixer
after decommissioning!
▪ For an extended period of decommissioning, carry out a 5‑minute function test at reg-
ular intervals (monthly to quarterly). CAUTION! A function test should only be carried
out under the applicable operating conditions. Never run the machine dry! Non-
compliance can lead to irreparable damage!
