1.7.5 Restarting the air conditioning unit in the case of breakdown
Some of the failure indicators on the screen are false. They are apparent breakdowns caused my some‐
thing other than operation of the unit; for example, air intake is blocked by an excess of accumulated
snow or the presence of refuse (plastic bags, papers, branches, etc.).
In this case, the unit can be restarted by pressing the MODE key on the thermostat repeatedly until the
display indicates OFF.
Then, restart the unit by pressing the MODE key and select the required operating mode.
The unit will start up normally if the cause of the fault is no longer present. If the cause persists, it is
possible to start the unit a maximum of three times within a 24-hour period.
If the thermostat display keeps showing the pilot light -1- and any fault code or if the air conditioner does
not start, contact a Johnson Controls Inc. Authorised Technical Assistance Service.
1.8 Regular maintenance activities for which the user is respon‐
sible
1.8.1 Maintenance Schedule
The air conditioning unit is designed to require as little maintenance as possible. Nevertheless, to ensure
smooth operations with a minimal use of electricity, a long working life and compliance with the regula‐
tions of each country, regular maintenance inspections must be made.
Johnson Controls Inc. shall not be considered responsible for any damage caused by improper mainte‐
nance of the 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 11 .
1.8.2 Maintenance responsibilities of the user
Like any other machine, the air conditioning unit requires regular maintenance, as the wear to which
some of its parts are subjected can effect 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 air conditioning unit is
installed.
As the air conditioner is installed on a roof, it is not possible that the user access it to carry out mainte‐
nance and upkeep.
There is no intent for the user to perform any maintenance tasks on the air conditioning unit.
D A N G E R
It is strictly prohibited for the user to carry out any maintenance or upkeep tasks on the air conditioning
unit.
Only trained Johnson Controls Inc. personnel with the necessary means and tools may carry out main‐
tenance and upkeep work on the unit.
Trained personnel must be aware of the health and safety regulations and procedures applicable to air
conditioning units. They should also be aware of general procedures and those applying specifically to
this unit.
Contact a Johnson Controls Inc. Authorised Technical Assistance Service for scheduled maintenance
on this unit.
