General
2. Operation and maintenance
3. Troubleshooting/appropriate action
The CTC EcoPart XL is designed to provide reliable operation and a high level
of comfort, as well as having a long service life. Here are some tips that may be
helpful and guide you in the event of an operational malfunction.
If a fault occurs, you should always contact the installer who carried out the
installation. If the installer believes the malfunction is due to a material or design
fault, then they will contact Enertech AB to check and rectify the fault. Always
quote the product's serial number.
3.1 Air problems
If you hear a rasping sound from the heat pump, check that it has been bled
properly. Top up with water if necessary, so that the correct pressure is achieved.
If this noise happens again, get a professional to investigate the cause.
3.2 Alarms
Any alarms and information texts from the CTC EcoPart XL are displayed on the
product used to control it or on the CTC Basic Display; for this reason you should
consult the appropriate manual for alarm codes.
When the installer has installed your new heat pump, you should check together
with the installer that the system is in perfect operating condition. Let the installer
show you where the power switch, controls and fuses are so that you know
how the system works and how it should be maintained. Bleed the radiators
(depending on system type) after about three days of operation and top up with
water if necessary.
2.1 Periodic maintenance
After three weeks of operation, then every three months in the first year. Then
once a year:
• Check that the installation is free of leaks.
• Check that the product and the system are free of air; bleed if necessary, see
the section Connecting the brine system.
• Check that the brine system is still pressurised and the fluid level in the brine
vessel is adequate/correct.
2.2 Operational stoppages
The heat pump is turned off with the power switch. If there is a risk of the water
freezing, drain out all the water from the CTC EcoPart XL.
