OPERATION OF AIR HANDLING UNITS
AND ACCESSORIES
WARNING
Before taking the air handling unit into
operation fit any unused connections with
protective mesh.
In addition, all electrotechnical and me
chanical safety devices must be
installed before taking the air handling
unit into operation.
– Before opening the unit check that its power has been
disconnected.
– Take care when opening the isolating valves for the hot
water to the air heater. There is a risk of water hammer
or steam discharge.
– When servicing or inspecting the unit, turn off the
safety switch before opening the inspection doors.
Reset all safety devices before restarting.
– The clearance in front of electric heaters and electrical
cabinets shall conform to applicable electrical safety
regulations.
– Use the control panel to stop the unit.
– The unit’s hatches are fitted with locking handles.
Ensure that the unit is always left locked, and that the
keys cannot be accessed by unauthorized persons.
– Do not open inspection hatches when the unit is in
operation.
– Use protective gloves during installation and service.
1. SAFETY INSTRUCTIONS

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 adYescent 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
connections 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 adYescent areas. For sensitive in
stallations 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 13.3.
3. TRANSPORT AND PLACEMENT
UNIT WEIGHT
Size 03 = 260 kg
Size 04 = 300 kg
Size 06 = 400 kg
SPACE REQUIREMENTS
Make sure that it is enough space around the unit for routine
service work, such as replacing filters and cleaning the fan and
casing.
Consideration has to be taken for future replacement of
com ponents.
PLACEMENT
The unit can be placed directly onto the surface if this is flat and
horizontal, otherwise use adjustable feet.

NOTE! The weight of the duct system
with components must not lay weight on the unit.
4. CONNECTIONS
4.1 DUCT CONNECTIONS
Size 03 (Ø250 mm) and 04 (Ø315 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 separate 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.
PIPE CONNECTION
Size 03 = 3/8”
Size 04 = 12 mm
Size 06 = 12 mm
Maximum operating pressure 3.0 MPa
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.

STARTING THE UNIT
When the electrical connections are made and all the accessories are mounted the unit is ready to start up.
1. Turn the safety switch to 1 (ON).
2. Start the unit.
DAMPERS
Check that all dampers opens and closes correctly.
VALVE ACTUATORS
Check that valve actuators for heating and cooling works correctly.
DIRECTION OF ROTATION
Check that the direction of rotation for the heat exchanger corresponds to the alternatives below.
LEFT-HAND VERSION:
The rotor should rotate upwards when looking from the front.
RIGHT-HAND VERSION:
The rotor should rotate downwards when looking from the front.
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 (R/W) 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.

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.
If the unit is supplied with Constant Air Volume control the air
flow can be read in the control panel.
