responsible

1.6.1 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.

1.6.2 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.
There is no intent for the user to perform any maintenance tasks on the HVAC unit.

  D A N G E R

This appliance is not destined for use by people (including children) with limited physical, sensorial or

mental capacities, or without adequate experience or knowledge, unless they have received instructions

or been supervised in the use of the appliance by an individual responsible for their safety.
Children must be supervised at all times to ensure that they do not play with the appliance.
Only  trained  Johnson  Controls  Inc.  personnel  with  the  necessary  means  and  tools  may  carry  out

maintenance and upkeep work on the unit.
Trained personnel must be aware of the health and safety regulations and procedures applicable to

HVAC units. They should also be aware of general procedures and those applying specifically to this

unit.
