Care and maintenance Shut-down
Temporary shut-down
1. Shut down the interior units
using the remote control.
2. Shut the unit off over the
internal control in the chiller (or
using the remote control).
3. Check the proportion
(percentage) of glycol.
4. Check the unit for visible signs
of damage and clean it as
described in the chapter "Care
and maintenance".
5. As much as possible, cover the
unit with a plastic foil to protect
it against the weather.
If only water and not a
mixture of water and glycol
is used, in regions subject
to freezing, water must be
drained from components
when these are at standstill.
The drained water volume
must be replaced when
components are put back into
operation!

Ensure that equipment and
components are disposed of in
accordance with local regulations,
e.g. using certified firms and
recycling specialists or at collection

to provide a list of certified firms
near you.
Regular care and observation
of some basic points will ensure

work, ensure the equipment
is isolated from the voltage
supply and secured to prevent
accidental switch-on!
