4. Remove the protective film from the fire protection plate and position the fire protection plate – (8)
in Figure 10.
5. Fit four washers – (17) in Figure 10 – and four bushings – (4) in Figure 10.
6. Turn the bushings until they rest on the floor.
5.2.3 Seal opening in the floor
If the unit is supplied with, for example, air, water or power from an opening in the floor, the opening
must be sealed with a flame-retardant foam as a precaution to prevent the spread of fire.
Two-component flame retardant foam from Würth (part number 0893 303 200) must be used.
The flame-retardant foam should be level with the floor, cover the entire opening in the floor and seal
all around the edges of the fire protection plate.
If the hole in the floor for the ground installations is deep, rockwool can be used to fill out the hole and
create a support for the flame-retardant foam.
Please note that the foam hardens very fast, approx. 50 sec at 22 o C .
Ready for cutting after approx. 90 seconds.

5.2.4 Positioning the unit stand
Position the four long rods – (5) in Figure 10 – in the bushings.
Check that the bushings and long rods are perpendicularly in the floor using a spirit level.
If the long rods are out of level, try to straighten out the bushings by applying force to the
side of the bushings.
Remove the four long rods to make installation of the unit easier.
Place the rubber unit base gasket on the floor over the bushings, as shown in Figure 13 and Figure 14.
Lift the unit stand and place it carefully on top of the rubber gasket, and make sure that the four
bushings in the floor are placed precisely under the four adjustment nuts in the unit base.
