6For your safety
2 For your safety
General
The service technicians assigned to working on the Condair MN must have read and
understood this service manual as well as the installation instructions and the operating
instructions of the Condair MN before starting work on the unit.
An understanding of the contents of the service manual as well as the installation and
operating instructions is a basic prerequisite for protecting personnel from danger, avoid-
ing improper operation and thus for the safe and proper operation of the Condair MN.
Personnel qualications
All work described in this Service Manual must be performed only by trained Condair
service technicians.
It is assumed that the service technicians are familiar with and will abide by the regula-
tions on occupational health and safety and accident prevention.
Hazards that may arise from the Condair MN:
DANGER!
Risk of electrocution
The Condair MN's central unit runs on mains power. If the central unit is open,
live parts may be touched. Touching live parts may cause severe injury or death.
For this reason: Before starting work on the central unit, disconnect it from the
mains power supply (remove plug from socket).
Warning!
System contamination hazard
If the Condair MN is switched off, there is a risk of the water supply line and
the internal water system becoming contaminated, as the water system is then
not being ushed regularly.
For this reason: The Condair MN must not be switched off after being commis-
sioned. This will ensure that the water system is purged at regular intervals,
and any contamination is counteracted.

7For your safety
Warning!
UV-C radiation
A UV lamp is built into the Condair MN's central unit. In principle this should
pose no risks, as it is installed in a radiation-proof housing. If the UV lamp is
operated outside of this housing, harmful UV-C radiation may be released. This
may cause damage to the eyes and skin.
For this reason: the UV lamp must never be operated outside of the protec-
tive housing. The central unit must be switched off and disconnected from the
mains power supply (remove the plug from the socket) before the central unit
is opened.
Warning!
Waste from damaged UV lamps may lead to injury and cause damage to human
health and harm to the environment.
For this reason: the waste from damaged UV lamps must be disposed of in
accordance with local provisions on hazardous substances and the site of the
damage must be cleaned properly.
CAUTION!
Leaky or defective water pipes/connections may lead to water damage.
For this reason: After replacing components, make sure the system is tight.

1. Mark the four attachment points of the mounting plate at the desired location using a level.
2. Secure the mounting plate to the appropriate place with suitable mounting hardware (not supplied).
Before tightening the screws, align the mounting plate horizontally using a level.
3. Hook the drain module into the tabs of the mounting plate and press down until it stops.
Important: Record the height difference in metres between the peripheral drain module(s) and the central
unit and convert to "centibar". This value must be entered when commissioning the system in the MN
service application (see Section 3.13.1).
Example:
– The drain module for spray loop 1 is 16.40 ft (5 m) above the central unit
– The drain module for spray loop 2 is 9.84 ft ( 3 m) below the central unit
This results in the following input values in centibar:
