15.2.5 Installation prerequisites
The water is supplied to the humidifier from a hose al-
ready installed at the factory (connection diameter
⅛" external thread).

The humidifier discharge is made into the condensate
collection tray.

Ensure that the condensate discharge is installed cor-
rectly (see section 6.3 "Connecting the condensate
discharge").

Alternatively, connect the optional condensate pump
(see section 15.5 "Condensate pump").
15.3 Electrical heaters
15.3.1 General information
This option is particularly suitable
– for low ambient temperatures at the installation loca-
tion of the IT cabinet, or
– for low thermal loads such as those which occur typi-
cally during the first phase after the installation.
The electrical heaters guarantee a constant supply air
temperature to the installed devices even for such appli-
cation cases.
This option must also be installed when the "Dehumidi-
fication" option is used (see section 15.4 "Dehumidifica-
tion").
Fig. 49: Electrical heaters
The deployed 2 kW heaters are switched on automati-
cally by the LCP DX controller when the average value of
the air temperature falls below a specified setpoint.
In case of "Room" operating mode, the air temperature
is the return air from the servers, while for "Rack" and
Water supply pressure range 0.1...6 bar
Water supply flow rate 0.6 l/min
Water supply Demineralised water
Discharge flow 7 l/min
Note:
Drinking water can also be used for operating
the humidifier.
– If the humidifier is connected directly to the
drinking water system, the technical regu-
lations for protecting the drinking water
must be observed.
– The water used to operate the humidifier
must comply with the requirements of
VDI 2035.
– If the humidifier is used together with a con-
densate pump, failure to observe the
VDI 2035 specifications can cause the
condensate pump to malfunction.
– Rittal recommends that the device is oper-
ated with demineralised water as the ser-
vice life of the humidifier may otherwise be
adversely affected, depending on the qual-
ity of the drinking water.
Note:
The humidifier can also be installed subse-
quently in a previously installed LCP DX. In
this case, contact Rittal Service (see sec-
tion 18 "Customer service addresses").
