Shutting Down the Unit

Temporary shutdown

1. Switch the system off using the remote control and

disconnect the main switch or fuse protection from
the power supply.

2. Check the outdoor part for visible damage.

3. Clean the outdoor part as described in the section

"Maintenance and Service" and, if possible, cover it
with a plastic sheet to protect it from weather condi-
tions.

Before any work on the unit is performed, it must
be disconnected from the power supply and se-
cured against switching on!

Maintenance and Service

Regular care and the observation of a number of basic
rules will ensure the unit long service life and reliable
operation.

Keep the unit free of dirt, plants and other deposits
and only clean the units with a damp cloth.
Do not expose the units to a direct stream water.

Do not use an abrasive cleaning agent or one that
contains solvent; if the units are extremely dirty, only
use suitable cleaning materials.

Before taking the unit out of operation for a longer
period of time, clean the plate fins of the outside part
while the ventilator is in operation and cover the out-
door part with a plastic sheet to prevent dirt from en-
tering the unit.

We recommend concluding a maintenance agree-
ment with a company who specialises in this type of
work.
This will guarantee that the system operates safely
at all times!

Permanent shutdown

For environmental safety reasons, the air conditioners
may only be disassembled by authorised service cen-
tres. REMKO GmbH & Co. KG or your contract partner
would be happy to provide you with the name of a serv-
ice centre in your area.

Troubleshooting

This unit has been designed based on state-of-the-art manufacturing methods and it has been tested repeatedly to
ensure that it is working properly. However, should problems occur, refer to the following list.
Please keep in mind that the outdoor part is controlled via the indoor unit. As a result, we recommend also reading
the section "Troubleshooting" in the operating instructions for the indoor unit.
Should the unit still not work after performing these functional checks, please contact an authorised service centre.
