 Place the new pleated filter (3285.700) at the rear of
the louvred grille.
 Extend the louvred grille to the rear and at the top of
the louvred grille labelled "Torx 30", turn the fasteners
at the left and right to the "Closed" position.
8.3.3 Maintenance of the fans
The installed maintenance-free fans are mounted on ball
bearings, protected against moisture and dust, and fit-
ted with a temperature monitor.
 Rittal recommends that the cooling unit fans should be
checked e.g. for unusual running noises after around
40,000 operating hours.
8.4 For the integration solution, remove the
cooling module
For service purposes and for its replacement, the cool-
ing module can be removed completely from the inte-
gration solution.
 First, disconnect all electrical connection cables from
the cooling unit.
 Loosen each of the two fastening screws on the left
and right (fig. 27, item 2) used to secure the cooling
unit onto the support rails.

4Limit stop

Pull the cooling unit forwards to the limit stop.
 Mount an eyebolt centred at the top of the cooling unit
(fig. 4).
 Secure the cooling unit with lifting gear and crane.
 Ensure that no persons are standing under a suspend-
ed load, even briefly, during crane transportation.
 Fasten the lifting gear to the crane hook to prevent the
load from moving because the centre of gravity of the
load can be eccentric.
 Finally, loosen the limit stop below the unit so you can
move the unit completely from the enclosure forwards.
9 Storage and disposal
 Store the cooling unit in the appropriate position for
transport.
The closed refrigerant circuit contains refrigerant and oil
which must be properly disposed of for the sake of the
environment. Facilities for disposal are available at the
Rittal plant or a specialist company. Give us a call (see
section 14 "Customer service addresses").
Warning!
When removing the cooling module from
the integration solution, there is the risk
of tipping caused by the centre of gravity
being moved forwards.
