Attach the damper to the ductwork at a distance of
around 2 m ahead of the fresh air inlet opening and to
the outlet ductwork at a distance of around 2 m from
the outlet opening. Install the actuators on the damper
shafts and to the corresponding connectors in the con-
trol housing. See chapter Connection of the electri-
cal wiring and the electrical equipment.
Adjust the damper in such a way that it is fully closed
when the unit is turned o and fully opened when the
unit is in operation. Other arrangements may damage
the unit.

All phases of the electric power supply must be
connected through a corresponding type of
circuit breaker. The distance between open
contacts must be greater than 3 mm.
The unit must be wired in such a way that it can
be disconnected from the electric power supply
using a single switch.
The unit must be connected to TN-S network, this
means that the neutral conductor must always be
connected.

READ CAREFULLY!
● Thesupplyandthecontrolcableshouldbeasfar
apartfromeachotheraspossible.
● Makesurethatthecablehasbeenproperlyin-
sertedintotheconnector.
● Becarefulnottodamagecableinsulationwhen
xingtheremotecontroltothewallortoother
surface.
● If you do not connect connectors or cables di-
rectly during the unit´s installation, protect
themagainstmechanicaldamageorshortcircuit
byaninsulatingtape.
● Cable connectors must not come into contact

6.4-4 Connection of the unit to
the BMS control system
The ventilation unit control is normally
equipped with the RS-485 interface.
For connection use a standard communication
cable. Connect the cable to the assigned
MODBUS connectors on the control board.
Connect the other end to the main control unit.
For the protocols details (ModBUS) contact
Barkell.
IMPORTANT NOTICE!
ItispossibletoconnecttheunittotheBMScontrol
systemandtheunitcontrolleratthesametime.
BMScommunicationisonlyavailablethroughthe
RS-485 Modbus interface. Other communication
protocolswillrequireagatewaytranslator.
ForadditionalinformationabouttheMODBUSco-
nnectionpleaseconsultthe THERM-X HRFLMod-
busProtocolmanual.
6.5 CONDENSATE DRAIN
CONNECTION
Condensate drain from the unit (either from the
recuperator, the cooling coil (if provided) or both
must be connected to the discharge pipeline.
If the unit has 2 drain connections an additional
trap or pump is required.
Ensure the unit is level or angled slightly towards
the condensate tray outlet to facilitate correct
conden-sate removal from the unit.
YOU WILL NEED
• 1siphon
• PVCdischargepipework
• sealtothedischargepipework
Siphon with a ball
The tube connection on the drain is connected
to the side discharge on the ventilation unit.
Ensure ALL connections are TRAPPED.
6. INSTALLATION
– Makesurethattheunitisinclinedby3°sothat
thecondensatedrainisensured.
