SOUND TRANSMISSION
When a unit is positioned next to a wall, low frequency sound can
generate vibrations in the wall, even if the sound level from the
unit is acceptable. Generally the unit should be positioned against
a wall to a room that is not sensitive for noise. When this is not
possible the unit should be positioned 400-500 mm from the wall.
Duct lead-through must be designed with care so that rigid con-
nections between the duct and wall do not occur. In addition, the
seal around the duct must be carefully installed to prevent the
transmission of noise to areas. For sensitive installations it may
be a good idea to connect ducts using flexible connections.
If the floor structure is weak, noise can be transmitted to other
areas in the building. Use of a heavy insulating mat can prevent
that problem.
TRANSPORT
Use a fork lift truck, pallet truck or platform trolley for transport on
site. The unit can be lifted from the front or from the side.
To move size 06 through a 900 mm opening remove the door and
the center strut. See section 12.3.

NOTE! The weight of the duct system
with components must not lay weight on the unit.
4. CONNECTIONS
4.1 DUCT CONNECTIONS
Size 03, 04 (315 mm) have circular duct connections. Size 06 has
rectangular duct connections (600 x 300 mm).
4.2 POST HEATER, ELECTRICAL
The electrical post heater for size 06 is duct mounted, see sepa-
rate instruction. The rectangular connection is PG on the unit and
the accessories. If the unit is selected with flange connection the
unit is delivered with an adapter for flange. This can be placed on
the unit or on the accessories. If the accessories are not placed
directly at the unit more adapters are available with the code
RDTZ-25-06-1.
4.3 POST HEATER, HOT WATER
Connect the pipes for the heating coil inside the unit according to
pictures below. View from gables.
NOTE! To avoid freezing the temperatures for frost
protection must not be set too low. If the building
has to be left unheated for long periods during
winter, the water must be drained from both the
pipework and the heating coil.
WARNING! Wear protective gloves
when using a fin comb.
Warning - hot water!!
FläktGroup takes no responsibility neither for
the connection of air heaters to the heating
system, nor for damage or injury caused by
incorrect planning, installation or maintenance
of this system. Pipework, valves etc. are to be
designed due to pressure drop and function, not
the dimensions of the air heater connections. The
weight of the pipe work system with components
must not lay weight on the water coil.
PREVENTING FREEZING
There is a risk of freezing in the hot water coil at low outdoor
temperatures. This can cause water damage. The risk can
appear:
1. if the temperature of the water is too high. The risk increases
in spring and autumn. Adjust the water temperature in relation
to the outdoor air temperature.
2. if the post heater is oversized. Decrease the temperature of
the water to increase the water flow.
FINS
Any deformed fins can be adjusted using fin comb EQAZ-14.
VENTING
The air must be properly vented from the system to ensure good
function. The venting is made through the pipe system.

6.10 AIR QUALITY SENSORS
Instead of external supply air duct pressure sensor an air quality
sensor can be connected to either measure the CO
2
or VOC.
6.11 EXTERNAL CONTROL/EXTENDED FUNCTIONS
The unit can be controlled by an external source, e.g. push but-
tons to activate profiles and profile bypasses. External control
inputs can also be used to vary fan speed from a remote source.
For configuration see chapter 9, control functions.
If configured, External Stop is a NC circuit which lets the unit
operate according to the current profile number. If the contact is
open, the unit is switched off and a message is shown on the
HMI.
External Control contacts are used as
1. NO circuits activating configured profiles with Ext. Control 1
being low and Ext. Control 2 high priority.
2. Push button circuits activating a profile bypass for a configured
time with Ext. Control 1 being low and Ext. Control 2 high
priority.
3. External setpoints for fan control (manual/volume flow/
pressure) with Ext. Control 1 being fan control 2 and Ext.
Control 2 fan control 1.
Please note that only two functions can be configured at the
same time for external controls.
6.12 FIRE PROTECTION FUNCTION
Two external fire alarms can be connected to the unit to stop it in
case of fire by using universal analogue inputs. Smoke detectors
and fire dampers cannot be connected directly to the air handling
unit, a separate fire system is needed.
Several functions which are activated if fire alarm is triggered
can be implemented. Therefor the fan speeds can be set inde-
pendently or completely stopped if needed.
6.13 SUMMARY ALARM
There are two separate alarm outputs for indicating A- and
B-alarms. Both can be connected as either NO or NC potential
free contacts.
6.15 7" HMI CONNECTION
6.14 UNIT OPERATION ON/OFF INDICATION
There is a digital output on the DDC that indicates whether the unit
is on/off.

STARTING THE UNIT
When the electrical connections are made and all the accesso-
ries are mounted the unit is ready to start up.
1. Turn the safety switch to 1 (ON).
2. Start the unit (see chapter 8).
DAMPERS
Check that all dampers opens and closes correctly.
VALVE ACTUATORS
Check that valve actuators for heating and cooling works correctly.
AIR FLOW MEASUREMENT
The eCO Side has measuring nipples for air flow measurement.
Using a measuring pressure Dpm (Pa) and a constant (k) the air
flow q
20
at 20 °C can be calculated using the following equation:
NOTE! When the unit is supplied with
Constant Air Volume Control there will be
no measuring nipples on top of the unit.
TEMPERATURE CORRECTION
The air flow formula above applies to air with a temperature of
+20 °C. At other air temperatures the air flow must be corrected
using the formula:
The value of the constant (k) is shown in the table below.
q

The measuring pressure, Dpm, is the difference between the
pressure in the empty section at the fan inlet and the pressure
inside the inlet cone. A manometer (RDTZ-56) can be connected
to view the measuring pressure. This is used as a reference for
monitoring the unit. Connect hoses with 4 mm diameter between
the nipples on the top of the unit and the manometer, see Fig. 1.
If the unit is supplied with Constant Air Volume control the air
flow can be read in the control panel.

Bypass current profile for a certain number of minutes by another
profile.
Change configuration of profiles. Unit needs a switch of profile
before applying changes to current operating profile.
The home screen will always contain at least 3x3 tiles. If the
configuration doesn’t include enough settings this tile will be used
as a placeholder.
CHANGING CONTROL TILE VALUES
To change the basic settings mentioned above there can be two
different ways. Press a control tile and one of the following menus
show up.
Setpoints are changed by using the control wheel, which can
easily be dragged to the desired value. Also, the up and down
arrows allow accurate setting by predefined steps. The amount
of each step depends on the control value that is edited (e.g. air
volume flow steps are 100 m³/h, regarding this is the determined
unit for air volume flow).
Control types are changed by using an option dialog, from which
the user can choose a preconfigured number of behaviours.
USING AUXILIARY TILES
Auxiliary tiles do not allow individual changes to the current
operation of the unit but most of them have a temporary or
permanent effect on its behaviour.
Profile bypass Allows to run another profile for up to 60 min
(5 min steps) and switching automatically back
to time scheduled profile afterwards.
