4. Installation
4.1 Foundation/Base frame
Before positioning the housing module, the foundation
and base frame must be checked for stability and a secure
seating of all threaded connections. The support surface
must be flat. Irregularities can result in door-twisting, lead-
ing to possible leaks and surface abrasion.
The support surface must be in horizontal level, in order
that draining of coils and trays are warranted.
Prior to positioning, the foundation and base frame must
be cleaned and free of ice.
Position the equipment on a level and secure foundation.
Irregularities must be compensated for with appropriate
base supports.
The foundation surface should correspond to the equip-
ment size. If a strip foundation (concrete or steel beam)
is used, the equipment must be supported on the outer
equipment frame.
For strip foundations, with equipment widths of over 2.0
m, cross-beams are also required under the equipment
start and ending, as well as under the component section
points.
Supporting point spacing between the equipment and
the foundation should be maintained to a max. 1.2 m in
length and width, while a max. equipment floor loading of
100 kg/m² should be heeded.
When determining the height of the foundation, the
required siphon height must be considered.
Freedom of movement of the doors, removability of
assembly elements and the fault-free sealing of assembly
connections depends upon exact alignment of the assem-
bly.
Equipment must be protected against construction dust
and contaminants, as well as damage until commission-
ing!
When equipment pieces are standing next to each other,
their foundation must also be supported at the midsec-
tion!
4.2 Equipment installation
Accessibility for repair and service work must be war-
ranted.
The equipment must be aligned horizontally and vertically
by means of base supports.
External installation
It must be observed that the roof frame is insulated, as
condensation build-up can occur!
Roof framing and weatherproof equipment are not a
substitute for roofing!
External component impact points are to be caulked with
the durable elastic and weather resistant sealing com-
pound as provided.
For roof units (weather resistant model), an additional tin
roof, rain covering will be provided.
The company reserves the right to make design changes without prior notice.
Assembly of the rain covering will be carried out at the
factory. Larger pieces of equipment will be only pre-
assembled, but must be bolted together and weather
stripped on-site.
Weather stripping will be carried out as follows:
Tape the sealing strip to the rain roof flange, caulk the
durable elastic sealing compound and cover with the loose
profiles as delivered. The covering profile is to be subse-
quently bolted to the rain roof flange.
Finally seal the gap on the inside of the unit between the
casing sections with elastic sealing compound.
If the paint finish is damaged during installation, this must
be touched up.
4.3 Structure-borne noise insulation
The equipment is to be installed, insulated from structure-
borne noise.
Foundation
In order to obtain structure-borne noise and vibration
insulation, the appropriate base supports (e.g. elastomeric
stripping) must on site be laid between the equipment
base frame and the foundation, whereby the manu-
facturer's information is to be observed. In general, the
equipment base should be supported under the face sides
and component attachment points and, if the component
length is greater than ca. 1.2 m, under the longitudinal
side, as well.
Ducting
The equipment is to be installed to the ducting system.
The decoupled ducting attachments for hygienic equip-
ment must not reveal any grooves or depressions.
4.4 Potential equalisation/Grounding
All non-conducting electrical attachment points must be
bridged over with a potential equalisation, e.g. flexible
attachments, ventilator motor unit. The entire assembly is
to be grounded.
