1.1 General
All staff concerned must acquaint themselves with these
instructions before beginning any work on the unit. Any
damages to the unit or parts of it due to improper han-
dling or misuse by the purchaser or the fitter cannot be
considered subject to guarantee if these instructions have
not been followed correctly.
The product identification label is affixed on the inspection
side of the air handling unit. Refer to the particulars on the
product identification plate when you contact Swegon.
The air handling unit is supplied in packaged condition.
Possible ordered accessories are supplied in separate pack-
aging with the unit.
1.2 Transport within the site
Before removing the transport pallet/transport cradle, if
used, determine whether a forklift truck or a pallet trans-
porter will be used for further transporting the unit within
the site to the spot where it will be installed.
1.3 Parts packed together with the unit
Components such as the commissioning plates, bolts and
document pocket are supplied in separate packaging and
delivered together with the air handling unit.
1.3.1 Document pocket
Secure the document pocket to the exterior of the air
handling unit or another appropriate place.
1.4 Arrangement
The air handling unit must be mounted horizontally on a
flat and firm supporting surface and this surface must be
constructed in a way enabling it to support the weight of
the unit.
When installing the air handling unit and connecting pipe-
work and electric cables, make sure that adequate free
space is provided for opening the inspection doors and
covers and withdrawing functional sections, such as filter
cassettes and fan assemblies, clear of the unit casing.
Inspection space required
A clear space of 1,000 mm should be provided in front of
the unit for opening the inspection doors.

1.7 To assemble the heat exchanger unit
section, if required (SILVER C RX only)
If the heat exchanger unit section is supplied in parts, they
must be jointed together. This can be done in two ways:
Alternative 1 is appropriate for use if there is sufficient free
space upward since this alternative is simpler. If sufficient
space is not available, Alternative 2 should be used.
If the heat exchanger unit section is supplied as one unit,
go on to Section 1.8.

1.7.3 Common for Alternatives 1 and 2
1.7.3.1 To adjust the rotor’s inclination
L
L
≈ 0,5xL
≈0,5xL
The illustration shows a suitable rotor inclination setting
for Fan Arrangement 1. The inclination must always be
towards the filter, which means that the inclination for
Fan Arrangement 2 is in the other direction.
The rotor’s inclination may need to be greater in ap-
plications that involve high airflows with associated high
pressure.
Slightly back off the locking bolts. Do not dismantle
the shaft bracket.
Adjust the inclination of the rotor by means
of the adjusting bolts. Tighten the adjusting
bolts equally.
When you have adjusted the inclination,
tighten the locking bolts.

1.7.3.2 Sealing plates/purging sector
Back off the screws
for the sealing plates/
purging sector. Arrange
the sealing plates/
purging sector so that
the bristles are against
the rotor. Tighten the
screws.
1.7.3.3 Pressing roller
Tension the pressing roller against the rotor hub until you no
longer can roll the pressing roller with your hand.
1.7.3.4 Vinyl-coated fabric seal
Slip the vinyl-coated fabric seal of the rotor (blue) over the rim
all the way around on both sides of the rotor.

1.8 Version and fan arrangement
1.8.1 SILVER C RX
The SILVER C RX 120 is delivered in a right-hand or a left-
hand version. The arrangement of the functional sections
can be vertically reversed (specify when ordering), see the
illustration below.
For particulars of the delivery configuration and installa-
tion of the relevant air handling unit, see the decal on the
lower section of the heat exchanger.
Outdoor air Supply air Extract air Exhaust air
1.8.2 SILVER C CX
The SILVER C CX 120 is supplied in the right-hand or a
left-hand version and with Fan Arrangement 1, 2, 4 or 5,
see the illustrations below.
For particulars of the delivery configuration and installa-
tion of the relevant air handling unit, see the decal on the
lower section of the heat exchanger.
NOTE!The supply air fan is marked 1; the extract air fan is
marked 2. These identifying decals are affixed to the inner
wall of the fan sections.
NOTE! If extract air flows through the lower level: The air
handling unit must be raised at least 50 mm (Higher than
the upper edge of the base beams) to provide space for
the water trap. This can be done by mounting adjustable
feet (accessories, a minimum of 24 feet).

1.9 The docking of unit sections
Place the fan, filter and possible coil heat exchanger
sections on top of one another, according to the deliv-
ery configuration (see Section 1.8). Secure the upper
section to the lower section with the bolts supplied,
screwing them into the pre-fitted rivet nuts (a total of
4 pcs.).
The illustrations in Section 1.10 show a SILVER C RX unit with Fan Arrange-
ment 2. The principle is however the same for the other units.
1.9.1 Fan/filter/coil heat exchanger sections (Coil
heat exchanger sections SILVER C CX only)
1.9.2 Fastening, front/middle section
Secure the fan/filter sections to the
heat exchanger section inside the
air handling unit’s middle section
using the supplied screws in the pre-
fitted rivet nuts (total 2x8 pcs.). The
anchoring points inside the unit are
shown in the illustration.
In order to access the anchor points
in the fan section, you must unfasten
the flexible connections and the fan
assemblies and move them outward
toward the inspection door. You can
then tighten the screws from the
opening of the duct connection.
NOTE! You do not need to remove
the fan assemblies completely!
Locate the fan/filter sections by the heatexchanger section
according to the delivery configuration (see Section 1.8).
Fix the fan/filter sections at thefront side of the air handling
unit to the heat exchanger section with the bolts supplied,
screwing them into the prefitted rivet nuts (a total of 2x4 pcs.).

Alt. 1
External fixing.
Dismantle the blanking plate and insulation inside the
cover on the rear side of the air handling unit. Secure
the fan/filter sections to the heat exchanger section
with the bolts supplied, screwing them into the pre-
fitted rivet nuts (a total of 2x4 pcs.). Refit the blanking
plate and the insulation.
Securing with screws at the rear of the air handling unit
can be done in two ways, internally or externally. External
fixing (Alt. 1) is appropriate for use if there is sufficient free
space behind the air handling unit, since this alternative
is simpler. If sufficient space is not available, Alt. 2) can be
used.

Internal installation.
Secure the fan/filter sections to the heat exchanger
section with the bolts supplied, screwing them into
the pre-fitted rivet nuts (a total of 2x4 pcs.). The
anchoring points inside the unit are shown in the il-
lustration.
In order to access the anchor points in the fan section,
you must unfasten the flexible connections and the
fan assemblies and move them outward toward the
inspection door. You can then tighten the screws from
the opening of the duct connection.
N.B.! You do not need to remove the fan assemblies
completely!
