General information
Preface
This manual contains technical data and information on installation, operation and maintenance.
Areas of use
TX 75A is a decentral ventilation unit for heat recycling in homes, which can be installed on a
window or wall.
Incorrect use
•The window models are not designed for point extraction, and are therefore not suitable for
this purpose.
•The unit is not fitted with a condensate pump or drain, and should not be used in humid
environments, such as bathrooms.
Deliverables
•Ventilation unit including TX control system
Mounting components:
•Mounting frame
•4 x M6 machine screws
Optional extras
•TX controller (control panel)
•CO2sensor
•PIR sensor (movement sensor)
•Facade grille

Function principle
The unit is designed to change the air in a room to ensure a better indoor climate. The TX 75A has
two fans which blow the same amount of air in as is extracted via a heat exchanger. The heat
exchanger is designed to heat cold outdoor air by transferring the heat from extracted air to the
intake air, reducing heat loss by approx. 85%. The heat exchanger can also be used to cool intake
air if the outdoor temperature is higher than the room temperature.
The air volume can be adjusted using a CO2sensor (optional extra) to ensure the level of air change
is in line with activity in the room.
Figure 1 - Function principle
Outdoor air is sucked in by the intake motor and blown through the intake filter. The air then passes
through the heat exchanger and out via the intake grille into the room.
Room air is sucked out by the extraction motor through the extraction grille. It is then blown
through the filter and heat exchanger into the open air.

Placing
The unit is usually placed on the wall by a window, with the
extraction grille near the ceiling. This position makes the
most of the coanda effect, which circulates fresh air well into
the room. This gives the air longer to mix with the existing
air in the room, avoiding drafts.
Installation on wall/window
Reinforcement according to local building regulations is
required between the unit and window, which permits the
window to be retained by min. 3 frame fixing screws. The
hole in which the unit is fitted must be minimum 200 mm
wide and 1210 mm high to take the mounting frame.
The mounting frame supplied is
attached to the reinforcement and wall,
or between two reinforcements (if the
unit is placed between two windows)
using suitable screws.
Connect the unit to mains electricity,
and fit it in the mounting frame using
the M6 machine screws supplied. The
holes are located by the unit air filter
the lowest behind the filter cover.
Finish off by sealing around the unit.
Refer to the sealant compound
manufacturer's instructions.

Service
Changing filter
We recommend changing the filter and cleaning the heat
exchanger once or twice per year. Remember to disconnect from
the mains before opening the front.
Open the front using a 6 mm Allen key (1). The locks are located
behind two holes in the side, and can be unlocked by turning the
Allen key anticlockwise, and locked by turning it clockwise.
The extraction filter (2) is easily accessible when the
cover is opened. Pull out the filter and replace with a
new one.
If the following is printed on the filter:
"Staubluftseite/Dust Air Side", the text should face away
from the heat exchanger. If there is no printed text, the
filter cannot be fitted the wrong way round.
To remove the intake filter, unscrew the two finger
screws (3). The cover (4) can now be removed and
filter taken out.
Ensure the filter is inserted correctly when replacing
with a new one. The side which must face away from
the heat exchanger (downwards according to the figure)
has the following printed text: "Staubluftseite/Dust Air
Side". If there is no printed text, the filter cannot be
fitted the wrong way round.
Replace the cover and tighten the finger screws.

Cleaning the heat exchanger
Requires two people!
Start by removing the door by slackening the 4 screws (1)
securing the hinges. One person should support the door and
the other remove the screws. This method avoids damaging
the hinges.
To remove the heat exchanger, remove the cover (2). To do
so, remove the 8 screws (3) with a Philips screwdriver.
When the heat exchanger is out, clean it carefully with a
vacuum cleaner.
Reassemble the unit after cleaning. Ensure the heat exchanger
is correctly positioned. The visible ribs on the sides must face
downwards and to the right, and upwards and to the left
respectively.

Mains connection
Connect Turbovex TX 75A to 230V AC mains electricity at the terminal clamp fitted behind the
cover on the end of the unit. Remove the cover by removing the four screws (M3 x 10 mm). Pass
the cable through the middle cable grommet in the cover, and connect the three wires to Phase,
Neutral and PE.
NB – Mains connection must only be performed by an authorised
electrician!
