9 - TROUBLESHOOTING
9.4 - Rectifying minor causes independently
Your heat pump is extremely maintenance friendly. To operate the
heat pump efficiently and without faults, you can rectify minor
causes simply on site.
Before you start:
■ Isolate the system from the power supply
■ Secure the system against unintentional reconnection
■ Before carrying out further work, wait at least 4 minutes after
switching off the power supply!
■ Check there is sufficient water in the heating circuit.
■ Check that the system pressure is adequate
You can optimise your system by checking the heating circuit and
DHW heating settings. Keep records and only adjust 1-2 settings
in a day.
9.5 - Heat pump repairs
Once a date has been agreed with or requested from CARRIER
customer service, repairs to your heat pump are carried out by a
trained customer service specialist on site. In order for service
work to be carried out, the accessibility of the heat pump and
auxiliary equipment must be ensured at all times!
9.6 - Customer service
We recommend an annual inspection (to assess the appliance's
actual condition) and if necessary maintenance (to restore it to its
expected condition) by CARRIER customer service.
In Germany, Austria and Switzerland, you can contact our
troubleshooting service:

9.7 - Cleaning
Protect the appliance from dust and dirt during building work. A
large plastic bag is provided for this purpose. A damp cloth is
sufficient to look after plastic and sheet metal parts. Do not use
any abrasive or corrosive cleaning materials.
