Cleaning and Maintenance
Operations you can carry out
• For air-source heat pumps, the circulation of air around the outdoor unit must not be
obstructed. Check regularly that nothing is obstructing the free circulation of air
(leaves, pollen, miscellaneous objects, toys, etc.).
• Check the water filters for fouling.
• Check for water leaks and traces of oil around the unit.
• Check that the batteries in your remote control are working correctly
Important:
Never clean the outdoor coil of the air-source heat pumps with a water cleaner
or high-pressure steam cleaner.
For operational air-source heat pumps, the defrosting cycles involve the release of
steam and water.
These cycles are normal and not dangerous. However, it is important to make sure the
water flows away properly to prevent the formation of an ice sheet.
Operations to be carried out by a professional from the STAC network every year:
• Leak detection on the refrigerating circuit by qualified personnel (sheet to be retained
for 5 years).
• Check that the electrical connections are secure.
• Check the condition of the water in the heating circuit: presence of sludge, etc.
• Check the glycol proportion and pH (if the mix needs topping up, always do so with
the same type of MONOPROPYLENE Glycol mix initially used).
• Record the unit's operating readings (attached to this manual).
