Top enclosure
Note
Removing the air-water radiator
The air-water radiator is very heavy. To make removal of the top enclosure easier, remove it
and then refit it after the operation is complete.
9.2.2.1
Air-to-water heat exchanger
Disassembly
1. Please observe the instructions of the heat exchanger manufacturer.
Air-water heat exchanger instructions (Page 129).
2. Shut off the feed and return pipes and use the discharge device to empty the heat
exchanger.
3. Undo the water lines and the connections for the leakage electrodes, flow meters, etc.,
where fitted.
4. Release the tensioning straps on the air-to-water heat exchanger.
5. Slide the heat exchanger slightly out of the top enclosure. The lifting eyes are then
accessible; attach a lifting gear to them to pull the heat exchanger out further. Use suitable
strap guiding or spreading devices for this.
6. There are two holes on the guide strip of the air-to-water heat exchanger for points at which
to secure it. Secure the heat exchanger with an additional sling rope and pull it out as far
as the center. Suspend the heat exchanger from the attachment point on the guide strip.
7. Pull the air-to-water heat exchanger out beyond the second hole and suspend it from there.
8. When the heat exchanger has been pulled all the way out, suspend it from the lifting eyes
at the rear and put it down carefully.
WARNING
The connecting flanges on the air-to-water heat exchanger are not suitable for lifting or
supporting.
The connecting flanges are not strong enough to bear heavy loads. The heat exchanger
can fall. This can result in death, serious injury or material damage.
● Do not stand the heat exchanger on the connecting flanges for the cooling water pipes.
● Do not suspend the heat exchanger from them.
