10.2 Dealing with faults
Various Faults "Er. XXX" as well as troubleshooting
options are displayed on the OTE controller. In the
event of a fault, your installer is your first point of
contact. The installer must be notified of the faults
and can provide you with valuable information for
troubleshooting. Your installer knows your
hydraulic system and how it operates. The causes
of faults can be found in the settings or hydraulics.
If it is nevertheless not possible to identify or
rectify the causes, OCHSNER customer service is
available to help.
10.3 Rectifying minor causes
independently
Your heat pump is extremely maintenance
friendly. To operate the heat pump efficiently and
without faults, you can remedy minor causes
simply on site.
Before you start:
•
Disconnect the system from the power supply,
•
Safeguard against unauthorised reconnection,
•
Ensure it is voltage-free,
•
Before carrying out any further work, wait at
least 4 minutes after switching off the power
supply!
•
Do not reach into the fan!
•
Do not remove the protective grille from the
fan.
Ensure that:
•
the evaporator is free from leaves and twigs or
other foreign bodies.
•
condensate can drain away.
•
there is sufficient water in the heating circuit.
•
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.
10.4 Cleaning and care
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.
Ensure that no ice is formed, especially around
walking surfaces and entrances around the
outdoor unit.
