10. MAINTENANCE AND WINTERIZING
During winter, or when the ambient air temperature falls below 0°C, drain water from the heat pump to
avoid damage to the titanium heat exchanger caused by freezing of water in the machine. This would entail
cancellation of the guarantee.
From time to time, check that machine gratings are not obstructed with dirt (dust, grass cuttings, pollen
and dead leaves, petals, etc.).
For maintenance interventions or scrapping, contact an approved maintenance centre.
