9.3 Transport
!
Material losses
If possible, transport the appliance to the installation lo-
cation in its original packaging.
If the appliance is transported without packing and with-
out using a pallet, its outer casing may be damaged.
Make sure that no objects drill through the outer enve-
lope of the appliance.
!
Material losses
Never use the air connections as handles for carrying
the appliance.
10. Installation
WARNING Electrocution
Do not install the appliance if it is damaged and there is
a risk that live components could be touched.
f Check the appliance for external damage.
!
Material losses
f Make sure that there are no sharp objects at the in-
stallation location that could drill through the outer
envelope of the appliance.
10.1 Mounting the appliance
!
Material losses
f Check whether the ceiling can bear the weight of the
appliance.
!
Material losses
f LWZ 130: Always install the appliance horizontally
so that any condensate arising can flow into the con-
densate drain.
Note
The filter cassettes are located at the bottom of the ap-
pliance.
Note
Install the appliance before mounting the ceiling panels
of the suspended ceiling.
Note
f When positioning the appliance, ensure there is
sufficient space to install the supply and extract air
ducts (see chapter "Preparations/ Specification/
Installation site/ Minimum clearances").
f Drill holes in the ceiling for mounting the appliance with
threaded pins or double ended screws.
f Fit the following parts onto each threaded pin in the se-
quence described.

f Use a spirit level to check whether the appliance is level
horizontally.
f Level the appliance horizontally by turning the nuts.
10.2 Connecting the condensate drain hose
Note
A condensate drain hose must not be connected in the
case of appliances with an enthalpy heat exchanger.
!
Material losses
The weight of the condensate drain hose and condensate
pump must not exert a leverage effect on the appliance
condensate drain connection. This could cause the con-
densate drain connection to leak or break off.
f Secure the condensate drain hose, e.g. to the ceiling.
!
Material losses
To ensure that condensate drains correctly, always lay
the condensate drain hose without any kinks. Lay the
condensate drain hose with a fall of at least 10%. Ensure
the appliance is level after installation.
The drain pipe may only contain one siphon. The con-
densate must be able to drain freely downstream of the
siphon.
The condensate must drain away via the domestic sewer
system. The pipes must not rise in the domestic sewer
system downstream of the siphon. The condensate drain
must be free from the risk of frost.
