9. Troubleshooting/Appropriate measures
The CTC EcoAir 600M 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 materials or design fault,
then they will contact us to check and rectify the issue. Always provide the
product’s serial number.
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.
Alarm
Any alarms and information texts from the CTC EcoAir 600M are displayed
in the product which is used to control it; you should therefore consult the
manual for that product.
Circulation and defrosting
If the circulation between the indoor and the outdoor unit is reduced or stops,
the high pressure switch is triggered.
Possible reasons for this:
• defective circulation pump/circulation pump too small.
• air in the pipes.
• condenser clogged.
• other intermediate obstructions to the water flow.
During defrosting the fan stops but the compressor operates and the melted
snow and ice flows into the condensation tray under the heat pump. When
defrosting stops, the fan starts again and initially a vapour cloud, consisting of
damp air which condenses in the cold outdoor air, is created. This is perfectly
normal and stops after a few seconds. If the pump heats poorly, check that no
unusual ice formation has occurred.
Possible reasons for this:
• defective defrosting automation.
• Lack of refrigerant (leakage).
• Extreme weather conditions.
