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 fi lters (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
effi cient maintenance. For an optimum result, TECHNIBEL air-conditioners must be maintained with TECHNIBEL maintenance
products.
• Air fi lter:
- Clean every two weeks. See "Operating instructions".
• Electric connections:
- Once a year, check that the electric wires are well fastened
to their terminals.
