3. Remove the mounting plate to enable access to the control board and connection of the ventilator to power supply and connection of other ventilators as stated in Unit
connection. To enable access to the control board in the mounting plate remove the four fixing screws.
Then disconnect the mounting plate from its fame with care and push it aside to enable access to the control board. While doing that avoid abrupt movements not to damage
the connecting cables between the control board and the mounting plate. Disconnect the mounting plate from the ventilation unit by disconnecting the two connectors. Re-
assemble the mounting plate in the reverse order. Install the cables with care.
4. Install the mounting plate unit using the supplied mounting template and expansion anchors.
Lean the mounting template
against the wall and mark four
holes for expansion anchors
as well as holes for routing the
cable.
Take o the mounting template,
drill the holes and insert the
expansion anchors.
Lean the mounting plate unit
against the wall and screw it
to the wall.
5. Install the air flow rectifier, the filter, the ceramic regenerator, one more filter and one more air flow rectifier inside the telescopic air duct.

diagram below. Connect the second ventilator with the third ventilator in the same way, ect. Up to 10 ventilators may be connected in series.
For easy electric installations use a 3G AWG18 (3G 1,0) cable and a 2xAWG23 (2x0,25) cable (not included in the delivery set). The cable must be rated for operation in an
alternating current power supply with the country-specific mains voltage.
Disconnect the power cable while connecting the second, third, etc. ventilator in series.
