4. Check the refrigerant pipelines.
5. Inspect the report on the cooling system leak test.
6. Visually inspect the cooling system.
7. Check the labels.
This inspection must be documented; see EN 378-2,
section 6.4.3. No cooling system may be operated with-
out the correct documentation.
The installer must document the fact that the system
was installed in accordance with the construction re-
quirements and state the safety and control device set-
tings, if adjustable, following commissioning. This docu-
mentation must be kept by the installer and presented
upon request.
6.6
Installing the server
As a general rule, the cooling system is designed for
"front to back" cooling – in other words, the devices in-
stalled in the enclosure must likewise follow this air rout-
ing. To this end, the area in front of the 482.6 mm (19")
level is supplied completely with cold air. The servers
draw the cooling air they require from this area, and ex-
pel the warm air downwards or sideways. The area at
the rear may reach a high temperature. This is intention-
al, since it increases the transmission performance of
the heat exchanger in the internal unit.
Distribute the equipment you wish to install evenly
across the 482.6 mm (19") level.
Close any areas you do not require with 482.6 mm
(19") blanking plates.
Cover the side opposite the internal unit in the enclo-
sure with an air baffle plate (see section 13 "Accesso-
ries").

Air baffle plate
Exchange the brush strip of the standard air baffle
plate in the TS IT server enclosure for the brush strip
with shorter brushes included with the supply of the
LCU DX.
The brush strip is included with the supply in two
parts.
Remove the top corner of the air baffle plate near the
TS frame using an angle grinder or other suitable tool.

Partition the remaining gap between the 482.6 mm
(19") level and the internal unit, as well as above and
below the internal unit, using the foamed plastic sup-
plied loose with the LCU DX.
Cut the foamed plastic to the required size.
