CTC EcoPart 400
General information
3. Operation and Maintenance
4. Troubleshooting/measures
The EcoPart Heat Pump is designed to provide reliable operation and high
levels of comfort, and to have a long service life. Various tips are given
below which may be helpful and guide you in the event of an operational
malfunction.
If a fault occurs, you should always contact the installer who installed your
unit. If the installer believes the malfunction is due to a material or design
fault, then they will contact the supplier to check and rectify the issue.
Always provide the product’s serial number.
4.1 Air
problems
If you hear a rasping sound from the heat pump, check that it is properly
bled. Top up with water where required, so that the correct pressure is
achieved. If this noise recurs, call a technician to check the cause.
4.2 Alarms
Any alarms and information texts from the CTC EcoPart 400 are displayed
in the product which is used to control it; you should therefore consult the
manual for that controller.
When the installer has installed your new heat pump, you should check
together that the system is in perfect operating condition. Let the installer
show you where the power switches, controls and fuses are so that you
know how the system works and how it should be maintained. Bleed
the radiators (depending on type of system) after around three days of
operation and top up with water if required.
3.1 Periodic
maintenance
After three weeks’ operation and then every three months during the
fi
rst
year. Then once a year:
• Check that the installation is free of leaks.
• Check that the product and the system are free of air; air bleed if
necessary, see the section Connecting the brine system.
• Check that the brine system is still pressurised and the
fl
uid level in
the brine vessel is adequate.
3.2 Shut-down
The heat pump is shut down using the operating switch. If there is a risk of
the water freezing, all the water shall be drained out from the heat pump!
