GENERAL MAINTENANCE:
All equipment must be properly maintained in order to provide optimum performance over time. Faulty maintenance can
result in the cancellation of the product guaranty. Depending on the products, maintenance operations consist in the
cleaning of filters (air, water), internal and external exchangers, casings, and the cleaning and protection of condensate
tanks. Treating odours and the disinfection of room surfaces and volumes also contributes to the cleanliness of the air
breathed by users.
TECHNIBEL proposes a wide range of perfectly adapted professional cleaning, maintenance and repair products for
complete and efficient maintenance. For an optimum result, TECHNIBEL air-conditioners must be maintained with
TECHNIBEL maintenance products.
