1.1.4 Regular maintenance activities for which the user is responsible
Maintenance Schedule
The HVAC unit is designed to require as little maintenance as possible. Nevertheless, to ensure the
correct operation of the unit with a minimal use of electricity, a long working life and compliance with the
regulations of each country, regular maintenance inspections must be made.
Johnson Controls Inc. shall not be considered responsible for any damage caused by improper
maintenance of the HVAC unit, which includes anything inconsistent with that described in this document
or others specifically provided with the unit.
To make them easier, maintenance tasks have been grouped by time intervals in a series of tables.
Maintenance responsibilities of the user
, see on page 24.
Maintenance responsibilities of the user
Like any other machine, the HVAC unit requires regular maintenance, as the wear to which some of its
parts are subjected can affect its mechanical reliability and the safety of those responsible for its
maintenance.
In compliance with current regulations, the unit must be regularly inspected and the results recorded on
the forms provided by the Labour and Health Authorities of the country where the HVAC unit is installed.
Users cannot access this form to perform maintenance and upkeep tasks on the unit.
