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.
•
Perform the following operations at least once per year
(the frequency of operations depends on the installation and
operating conditions):
- Check the composition and condition of the coolant.
- Check operating points and setpoints.
- Check the safety devices:
- Dusting of electrical boxes.
- Ensure that all electrical connections are properly tight.
- Check the ground connections.
- Check the hydraulic system (cleaning of the filter, water quality, purge, flowrate, pressure etc.).
