24 Operation
4.5 Decommissioning the system
In order to take the humidification system Condair DL out of operation (e.g., to perform maintenance)
perform the following steps:
1. Close the shut-off valve in the water supply line.
2. Switch off
<Control unit On/Off> switch on the control unit, and if applicable deactivate control unit
via the external enable switch.
3. Disconnect then control unit from the mains supply : switch off electrical isolator in the mains
supply line and secure electrical isolator in the "Off" position against accidentally switching on.
DANGER!
Risk of electric shock!
The frequency converter in the control unit of systems with booster pump contains capaci-
tors. These can remain charged with a potentially deadly voltage for a certain period of time
after the control unit has been disconnected from the power supply. Therefore, wait at least
10 minutes after disconnecting the power supply. Then make sure the appropriate contacts
on the frequency converter and the terminals on the pump motor are free of voltage before
starting any work on these components!
4. Mind hygiene! Let the fan of the ventilation system run until the humidification unit is dry .
5. If work has to be carried out on the humidification unit switch off the AHU and secure the system
against accidentally being switched on.
Important information on extended periods of non-use
Important!
For reasons of hygiene, we basically recommend that the control unit and the supplying re-
verse osmosis system should be left switched on. With the system switched on, the water circuit is flushed
at regular intervals to eliminate standing water and reduce the risk of contamination in the supply lines.
If the humidification system Condair DL is not be used for a longer period of time observe the following
points:
–
Mind hygiene! Drain all water conduits .
Note: Regarding the emptying of the water supply line from the RO system please refer to the speci-
fications of the manufacturer of the RO system.
– Remove the sterile filter, drain the water in the filter housing, dry filter housing and install a new filter
cartridge.
– Drain the Ag ionization cartridge.
– For safety reasons the
post-evaporation elements should remain in their working position ,
even if the humidifier is not used for an extend ed period. This prevents the water from being sprayed
directly into the duct in case the humidifier is powered up inadvertently.
