Qualicationofpersonnel
Repair work must be carried out only by qualiedandwelltrainedprofessionals authorised by the
owner.
Repair work relating to the electrical installation must be carried out by an electrician or professionals
authorised by the owner.
General notes

Safety
Before starting repair work on the Condair RS set the unit out of operation and disconnect it from the
mains (see chapter 4.5).
DANGER!
Make sure the Condair RS is separated from the mains (check with voltage detector) and the shut-off
valve in the water supply line is closed.
CAUTION!
The electronic components inside the control compartment of the Condair RS are very sensitive to
electrostatic discharge.
Prevention: Before carrying out any repair work to the electrical or electronic equipment of the Con-
dair RS, appropriate measures must be taken to protect the respective components against damage
caused by electrostatic discharge (ESD protection).
7.2 Fault indication
Malfunctions during operation detected by the control software are indicated by a corresponding Warning
message (operation still possible) or Fault message (operation not longer possible) in the maintenance
and fault indication eld in the standard display of the control unit.
Warning
Temporary problems (e.g. water supply interrupted for a short time) or malfunc-
tions which cannot cause damage to the system are indicated with a warning
message. If the cause of the malfunction disappears of its own accord
within a certain period of time, the alarm message will automatically
switch off otherwise an fault message is triggered.
Note: warnings can be indicated also via the service relay of the remote op-
erating and fault indication. Therefore the warning indication via the service
relay must be activated in the communication menu of the control software
(see chapter 5.4.5).
