5.5. Outdoor installation

ATTENTION:
When the pump is to be installed outdoor, we recommend that the motor
is fitted under a rain cover.

5.6. Hot surfaces

DANGER:
When hot liquid is to be pumped, it must be ensured that people cannot
accidentally touch the equipment hot surfaces.
Figure 13 shows the parts in the pump that may get as hot as the hot liquid being
pumped.
