Positioning

The R NexPolar devices must:
— be positioned on a level surface that's capable of supporting
their weight
— be positioned on a sufficiently rigid surface that will not
transmit any vibrations to the underlying or adjacent rooms
It is recommended to place a rubber slab (hardness 60 shore, thick-
ness 10 mm.) or properly sized anti-vibration supports between the
device and its support surface.
The unit should be raised off the ground, as follows:
— 100 mm for installations in ordinary zones.
— 300 mm for installations in zones that are extremely cold or
subject to heavy snowfall

Adequate antifreeze systems should be used for installations
in zones that are extremely cold or subject to heavy snowfall,
where the possibility of freezing is present.

While operating in heating mode, the unit generates conden-
sation, which will be deposited on the support surface. This
could freeze if the outdoor temperatures are below zero, thus
creating a hazard. In this case, appropriate barriers should be
installed in order to prevent people from approaching the unit.
