Transport
1. Transport
The AHU is delivered in 3 or 4 sections, which are to be assembled on site. The AHU can be lifted by fork-lift or by crane
using suitable lifting straps.
1.1 Accessories
Accessories such as adjustable feet, Disc-Lock, water trap for
condensate water from plate heat exchanger and cooling coil,
spare filters (to be ordered separately) and other loose items,
are packed into a box and put inside the AHU. On the outside
of the unit section, in which these items are placed, will be a
red sticker. Duct connection parts are also placed inside the
AHU (with exceptions). Remember to remove transport fixing
pieces. These are identified by red stickers.
1.2 Unloading by fork-lift
The forks must be long to avoid damage of the underside of
the AHU.
1.3 Unloading by crane
The straps must be secured to the supporting legs as shown in
the illustration. Avoid that the straps press and cause deformation to the top of the unit. Keep the straps on sufficient distance from the unit - use bars or similar - see the illustration
1.4 Pre-assembly storage
The AHU must be protected from weather and impact. The
protective plastic film wrapped around the unit must be removed on arrival on the site and the unit covered with tarpaulin or similar material. In order to minimise condensation, sufficient air circulation must be ensured between the covering
and the unit.
Avoid that the straps press and cause deformation to the top
of the unit. Keep the straps on sufficient distance from the
unit - use bars or similar

Installation of units and ducts
Minimum distance to
the ceiling - 700 mm
2. Installation mechanical
NB! When positioning the unit on the site, it must be ensured
that:
The necessary space requirements for service and inspection in
front of the unit are met. It is recommended that a distance
corresponding to the unit s width is kept free for service and
inspection in front of the unit.
The necessary space requirements for access to the
switchboard over the unit are met. It is recommended that the
distance between switchboard and ceiling is at least 700 mm
2.1 Floor
The floor must be level and even for the unit. The building
construction and floor must be able to resist the load of the
AHU. In the case of lightweight construction that might transmit noise and vibrations, tor especially sensitive areas, the unit
must be placed on an absorbing foundation. The adjustable
feet, delivered with the unit, must be replaced by vibration
absorbing material.
2.2 Install the adjustable feet before the sections are
pushed together
The adjustable feet must be fitted in the supporting legs to
level the sections before the sections are pushed together.
2.3 Assembling the AHU sections
Sections are kept together with the Disc-Lock system.
1. Ensure that the factory fitted rubber sealings are undamaged
2. The sections are then to be positioned directly opposite each
other. The feet must be adjusted to get the profiles parallel and
to get the pairs of locking pins for the Disc-Locks at the same
height.
3. The sections must then be pushed together so that the rubber
profiles fit directly into one another (please see the illustration).
Press the sections carefully together to ensure that the DiscLocks will not be used for pulling the sections together.
4. The sections are then to be locked together using the DiscLock system. Place a Disc-Lock on each pair of locking pins.
Each section is prepared for a Disc-Lock at the vertical part of
every corner usually 4 Disc-Locks between 2 sections.
Tighten the Disc-Locks loosely with the supplied tool, until
the sections are pressed hard against each other (please see the
illustration).

The pipes on the heating coil for hot water and cooling coil
for chilled water have external thread. If the unit is ordered
with valve motors and control valves, the valve motors and
control valves are packed in cardboard boxes and the boxes
are placed inside the air handling unit
If the unit is ordered with a cooling coil, a water trap for the
condensate is included in the delivery, and the water trap is in
a cardboard box inside the air handling unit. If the unit has a
plate heat exchanger, a water trap for the condensate is included in the delivery, and the water trap is in a cardboard
box inside the air handling unit.
3.1 Free access to extract components for inspection,
cleaning and repair/replacement
It must be ensured that pipes, cables etc. do not obstruct the
inspection doors and that fans and heat exchanger that can
be extracted from the unit can be withdrawn freely from the
unit.
3.2 Pipe connection to coils
Pipes for hot water must be protected by insulation against
frost and loss of heat. Further protection against frost can be
obtained by installing electrical heating wires around the
pipes and under the insulation combined with temperature
sensors and a control system. Circulation pumps in pipe systems are able to improve sufficient supply of hot water protecting the pipes further against frost (pipes, insulation, electrical heating wires, control system for heating wires and
circulation pump are not delivered by Systemair).
Pipes for cooling must be protected by insulation against
loss of cooling in the summer (pipes and insulation is not
delivered by Systemair). The coil and pipes from the coil are
not constructed to withstand the weight and stress from long
pipes and insulation of pipes. The system must be supported
carefully in rigid bearings to roof, floor and walls.

Plumbing
3.2.1 Pipe connection to heating coil
The heating capacity of the coil with only 2 rows is independent
of the connection of the hot water in equal flow or in counter
flow to the direction of the air. The pipes on the heating coil are
marked for inlet at the bottom and outlet at the top and this is OK
for air flow from the left side as well as from the right side.
NB! If Glycol is added, the Glycol must be without additives and
auto glycol must not be used.
Automatic bleeding have to be installed at the highest point of
the 2 pipes
supply- or return pipe.

3.5 Draining of condensate water
Drip trays to collect condensate water are installed under plate
heat exchanger and cooling coil. Each drip tray is provided with
a drainage outlet. To avoid freeze ups and frost bursts of pipes,
sufficient insulation is recommended and installation of heating
between the pipes and the insulation could even be necessary
(insulation and heating is not included).
3.5.1 Draining from plate heat exchanger
The drip tray under the plate heat exchanger works under negative air pressure. To ensure that the water escapes from the tray
under the plate heat exchanger, a water trap is included in the
delivery, but not installed.

Electrical connection
4.1 Quick guide for the installation.
Before shipment the unit has been assembled and has passed a
final functional test. A copy of the test report is delivered with the
unit. After the final test the unit is divided into separate sections to
facilitate the transport. When the unit has been reassembled on the Step 1 - Cables in winches prepared for connection
building site, the cables between the sections must be reconnected
to the terminals in the switchboard. The cables are marked for
reconnection.
Cables to external components are included in the delivery and the
cables are connected to all external components. All external components with connected cables are packed into a cardboard box placed besides the switchboard on the top of the unit.
Step 1: Cables prepared for connection.
The cables to be connected to the terminals in the switchboard
are very visible in the small winches. Make the cables free for
connection.
Step 2 - Pull back cables to the board
Step 2: Pull the cables through the cable entries
Pull the cables through the rubber seal in the roof panel, behind the switchboard. Pull the cables through the cable entries
on the back of the switchboard
Step 3: Install the cables in terminal blocks
All cables are marked with numbers. Install cables in terminals
with the corresponding numbers.
Step 4: Install external components
These are the supply air temperature sensor, valve motor(s) (if
requested), control valve(s) (if requested), sensor for water temperature in the heating coil (if water heating coil was requested),
circulation pump (if water heating coil in the system), 2 air pressure transmitters if it is a solution for constant pressure in the
ducts, a repeater (if requested) - see the information below under
step 9 about external components.
Step 3 - Reinstall in the board
Step 5: Install cables from external components and cable for
mains supply. It must be ensured that cables do not obstruct the
inspection doors and that fans and heat exchanger can be withdrawn freely from the unit.
12
Electrical connection
Step 6: Install the Systemair Control Panel.
The Systemair Control Panel with cable is in a box on the top
of the unit and the Systemair Control Panel is connected to the
controller inside the switchboard because the cable with socket
is pulled through a cable entry in the switchboard. Mount the
Systemair Control Panel on the wall and take into consideration
that the cable is 10 metres long.
If the installer on the final site must pull the cable through a
narrow whole in a wall because the unit is in one room and the
Systemair Control Panel in another room, the installer must
demount the cable on the backside of the Systemair Control
Panel - pull the cable through the narrow whole - adjust the
length of the cable and remount the cable (Wiring diagram
about the cable colours and terminals are show here to the
right).
The control Panel is supplied with power from the controller,
and it is not possible make this cable longer. If 10 metres of
cable is not sufficient, a repeater must be installed between the
Systemair Control Panel and the controller. This is described in
step 8 below.
13
Electrical connection
Step 7: Pressure transmitters over the fans for control
in m3/h.
If the air handling unit was ordered for control in m3/h
through the supply fan and the exhaust fan, the pressure
transmitters are installed inside the unit by the factory. The
system has been tested, - no installation to do - this is ready
for start-up.
Step 7 - pressure transmitters in the ducts
or
Pressure transmitters in the ducts for control of duct
pressure in Pa.
If the air handling unit was ordered for control in Pa of pressure in the ducts, the air volume from the air handling unit
must be adapted continuously to maintain the set point pressure in the ducts. With control of pressure in ducts, there are
no pressure transmitters installed inside the unit over the
fans, but the pressure transmitters must be installed in the
main ducts one pressure transmitter in the main duct for the
supply air and one pressure transmitter in the main duct for
the exhaust air. The pressure transmitters are packed in a box
placed beside the switchboard on the top of the unit. The
pressure transmitters are connected in the switchboard.
Pressure transmitter
installed on duct
Exhaust: Install the
hose on minus for negative pressure
Supply: Install the hose
on plus for posivtive
pressure
It is important to select positions for the pressure transmitters without heavy turbulences in the ducts, because stable
signals to the controller are very important.
Step 8 - Installation of supply air sensor
Step 8: Installation of supply air temperature sensor
The supply air temperature sensor is packed in a box placed
inside the unit. Drill a hole in the supply air duct at least 1
2 metres away from the heating or cooling battery and mount
the sensor.

Electrical connection
Step 9 Details about electrical connection of external components
Repeater
If the distance between controller and control panel is
more than the 10 metres of cable from the control panel
allows, the repeater EO-R is necessary. Simple extension of the cable without the repeater will lead to malfunction and severe problems. Up to 1200 m cable
length between the controller and the repeater is possible. The distance between the repeater and the control
panel is restricted to the 10 metres of cable from the
control panel. Supply voltage for the repeater is 24 V
AC from the switchboard and protection class is IP20.
One control panel is able to control up to six air handling units through one repeater with an E28 controller
in each air handling unit.
Repeater type EO-R
Extended operation (Push button)
When the unit is running at reduced speed or is in shutdown mode, it can be forced up one step by using a
Push button (impulse). Chose the required number of
minutes for The Extended operation in the control
