2. General
2.1 Handling the air handling
unit before commissioning
The air handling unit and its duct connections should be
protected against wetness and condensation until the unit
is commissioned.
2.2 Range of Application
The SILVER C units are designed for use in comfort ventila-
tion applications. Depending on the variant selected, the
SILVER C units can be utilised in buildings such as office
buildings, schools, day nurseries, public buildings, shops,
residential buildings, etc.
SILVER C units equipped with plate/coil heat exchangers
(PX/CX) and separate supply air and extract air handling
units (SD) can also be used for the ventilation of moder-
ately humid buildings; however not where the humidity is
continuously high, such as in indoor swimming baths.
The separate SILVER C supply air and extract air handling
units (SD) are designed for applications in which the sup-
ply air and extract air flows need to be completely sepa-
rated from one another or where, due to limited available
space, separate units for supply air and extract air respec-
tively are needed. They can also be used individually if only
one of the variants is needed.
In order to fully obtain all the benefits the SILVER C system
has to offer, it is important keep in mind the air handling
unit’s special characteristics in conjunction with designing
the project, installation, commissioning and operating the
system.
The air handling unit in its basic design should be installed
indoors. The TBTA/TBTB accessory should be used if the air
handling units are installed outdoors.
Important!
Always read the safety instructions in Section 1 that
explain the risks involved in running the unit and
designate who shall be permitted to operate and
service the unit, and carefully follow the installation
instructions provided in each paragraph.
The product identification plates are located on the in-
spection side of the air handling unit and on a wall inside
the fan section. Refer to the particulars on the product
identification plate when you contact Swegon.
2.3 Mechanical Design
The SILVER C is available in 9 physical sizes and for 18
airflow ranges.
External and internal material: aluminium-zinc plated
sheet steel. Environmental Class C4. Panel thickness of
52 mm with intervening insulation consisting of mineral
wool.
The size 11-30 SILVER C units with plate heat exchanger
(PX) or rotary heat exchanger (RX) with air intake from
above and the separate size 04-08 supply air and extract
air units (SD) as well as the SILVER C RX Top are equipped
with pleated, class F7 filters. The units in other variants/
sizes have class F7 supply air and extract air filters made of
glass fibre.
The type RECOnomic or RECOsorptic rotary heat exchang-
ers are variable speed of rotation controlled and have a
temperature efficiency of up to 85%.
The plate heat exchangers are as standard equipped with
bypass and shut-off dampers for variable and automatic
control of the heat exchanger’s efficiency on heat recovery.
Pipework packages in unassembled form are available for
the size 35/120 SILVER C CX one-piece units and for the
size 12-120 SILVER C SD separate supply air and extract air
handling units.
The supply air and extract air fans are of SILVER C Wing+
type, an axi-centrifugal fan with backward-curved blades.
The fans are direct-driven and have a motor control system
for variable speed control.
2.4 Environmental Documenta-
tion
For a complete Declaration of Construction Materials, see
our home page at www.swegon.com (applicable to Swe-
den only).
The air handling unit is designed in such a way that it can
be easily dismantled into its component parts. When the
unit has ended its useful product life, the services of an ac-
credited recycling company should be utilised for disposal.
Approximately 94% of the parts in SILVER C air handling
units are recyclable.

have any questions regarding the dismantling instructions
or the air handling unit’s impact on the environment.
2.5 To run internal cables
The installation and wiring work must be carried out by a
qualified electrician.
Cables from external sources can be run into the air han-
dling unit through the rubber diaphragm on the rear side
of the junction hood (RX 04-30) or on the inspection side
of the unit (Other sizes).
The unit is equipped with cable holders in the centre sec-
tion and cable grommets and rubber diaphragm between
the unit sections. The internal running of cables must
be run in a safe manner and follow applicable rules and
standards.
