3.0 Installation of the Units

Installation of the three XBOXER 55 units, including all external
services and controls should be installed in accordance with
the appropriate authority and MUST conform to all governing
regulations e.g. CDM, CIBSE, IEE, and in strict accordance with
the applicable Building Regulations.
Having decided on the correct installation position for the units,
appropriate external wall grilles must be installed located to
combine with the spigots on the out facing side of the Mixing Box:
The three supplied units must be installed on the ceiling in the
following order:
1. The Mixing Box/Side Silencer must be installed first,
positioned against the outside wall.
2. The Central Fan Unit is the second unit for installation.
3. The third unit to be installed is the Room Side Silencer.
Installation begins by removing the 28 Cap Head fixing bolts and 3
ceiling mounting brackets (one for unit see figure 4).
The final assembled position of the units on the ceiling, must allow
for sufficient free space to be available adjacent to the units for
future inspection, maintenance, repair and replacement.
Mark positions for mounting the ceiling brackets for each of the
three units ensuring that the fixed brackets on the units will fit
into the same ceiling brackets they were first removed from.
(see figure 5 and 5a).
As previously mentioned the Mixing Box/Side Silencer must be
installed first, positioned against the outside wall.
Ensure that the fixed ceiling brackets will allow for the weight of
the XBOXER 55 units to be suspended from them. The first unit the
Mixing Box/Side Silencer may be lifted up to be aligned and
installed using the Cap Head bolts (see figure 6).
