5INSTALLATION
5.1 INSTALLATION KIT
The included installation kit contains all necessary components for the installation – both for
installation on concrete floor, wooden floor or on a steel installation plate.
Figure 11 – Installation kit (AN-210)
5.2 INSTALLATION OF THE UNIT STAND
Make sure to place the unit stand correctly in the operatory. See Figure 1.
Prior to drilling holes in the floor, be sure that the supplies and connections have
been laid out correctly in accordance with the requirements mentioned in section 2.1.
Start by placing the 1:1 installation plan (YB-235) on the floor and mark the five hole-positions shown
on the drawing.
For this purpose, a steel drill template can be supplied (AP-919).

XO FLEX – Installation instructions Installation
16
As the floor in the dental operatory is not completely horizontal the unit stand is
designed to be installed on bushings and lifted about 5 mm from the floor surface.
To tighten the gap between floor and unit base a rubber gasket is supplied.
INSTALLATION OF THE UNIT IN A CONCRETE FLOOR
1. Drill four holes for fitting the unit stand. Use drill Ø18, drilling depth min. 105 mm.
2. Drill one hole for fitting the support leg. Use drill Ø10, drilling depth min. 80 mm.
Make sure to drill the holes precisely with a tolerance of + 2 mm.
Also, be sure to drill the holes perpendicular to the floor surface.
If the above is not completely respected, it will be difficult to push the rods through
the holes of the unit base!
3. Remove dust from the holes.
4. Fit four expansion Ø18 anchors – (18) in Figure 11 – and one Ø10 expansion plug – (1) in Figure
11 – into the holes, flush with the floor surface, using a hammer.
5. Assemble the four parts as shown in Figure 12 – see also parts (4), (8) and (17) in Figure 11.
Figure 12 – Pre-assembly of mounting accessories
6. Use this assembly to secure the expansion anchors. Use a torque wrench and tighten to 75
Nm.
7. Once the expansion anchors are tightened to the correct torque, remove the hex cap screw at
the top (1) in Figure 12. Use a wrench to hold the bushing (4) in Figure 12, while unscrewing the
hex cap screw.
8. Remove the bushings and the washers and place the fire protection plate (9) in Figure 11. Re-
mount the washers and the bushings and continue at 5.2.4
INSTALLATION OF THE UNIT STAND IN A WOODEN FLOOR STRUCTURE
1. Start by drilling the hole to fix the supporting leg, Ø 6 mm.
2. Then drill the four other holes, Ø 8 mm.

XO FLEX – Installation instructions Installation
17
Make sure to drill the holes precisely with a tolerance of + 2 mm.
Also, be sure to drill the holes perpendicular to the floor surface.
It the above is not completely respected, it will be difficult to push the rods through
the holes of the unit base!
3. Insert the four mounting bolts – (6) in Figure 11 – in the 8 mm holes and tighten the screws until
the heads are approx. 24 mm above the floor surface.
4. Place the fire protection plate (9) in Figure 11.
5. Fit four washers – (17) in Figure 11 – and four bushings – (4) in Figure 11.
6. Turn the bushings until they rest on the floor.
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.
Figure 13 – sealing the floor installations with flame-retardant foam
5.2.4 POSITIONING THE UNIT STAND
Position the four long rods – (5) in Figure 11 – 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.

XO FLEX – Installation instructions Installation
18
Place the rubber unit base gasket on the floor over the long rods, as shown in Figure 14 and Figure
15.
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.
Figure 14 – Positioning of the rubber gasket
Figure 15 – Positioning of the two parts
When lifting the unit stand, use the carrying handles – see Figure 16.

XO FLEX – Installation instructions Installation
19
Figure 16 – Lifting the unit stand
Adjust the rubber gasket for accurate positioning under the unit base and the supporting leg.
Place an 8mm washer – (10) in Figure 11 – and an M8 screw – (9) in Figure 11 – loosely into the
supporting leg.
Insert the four long rods – (5) in Figure 11 – through the four holes of the unit base into the
bushings in the floor and tighten.
Place four Ø12 washers – (12) in Figure 11 – and M12 nuts – (11) in Figure 11 – loosely on the
studs. See Figure 17 and Figure 18.

Figure 18 – Adjusting the unit base, (1) adjustment nut and (2) bushing in the floor
ALIGNMENT OF THE UNIT BASE
1. With the special wrench (MG-416), adjust the brass adjustment bushing – (5) in Figure 19 –
in the supporting leg and allow for approximately 10 mm clearance between the supporting
leg and the floor surface.
2. Fit the screw and the washer – (9) and (10) in Figure 11 – in the hole through the adjustment
bushing – (5) in Figure 19 – do not tighten.
3. Turn the adjustment nuts – (1) – (4) in Figure 19 – into the unit base, allowing for
approximately 5 mm clearance all the way between the unit base and the floor surface, and
make sure that all four adjustment nuts are resting on the bushings in the floor. The nuts on
top of the long rods should be loose.
4. Place a spirit level on top of the bridge arm post in the longitudinal direction – (A) in Figure
19 – see Figure 20.
5. Turn the adjustment nut – (2) in Figure 19 – until the post is plumb in the longitudinal
direction and then tighten the nut on top of the long rod.
6. Turn the spirit level to adjust the unit stand in the cross-wise direction – (B) in Figure 19 –
see Figure 21.
7. Turn the adjustment nut – (4) in Figure 19 – counter-clockwise and make sure it does not
contact the bushing in the floor.
8. Turn the adjustment nut – (3) in Figure 19 – until the bridge arm post is horizontal in the
cross-wise direction and tighten the nut on top of the long rod.
9. Turn the adjustment nut – (4) in Figure 19 – clockwise until it contacts the bushing in the
floor and tighten the nut on top of the long rod.
10. Turn the adjustment nut – (1) in Figure 19 – clockwise until it contacts the bushing in the
floor and tighten the nut on top of the long rod.
