Sensor Installation
The TJ-K10K sensor is positioned in the To Atmosphere (Stale air
Out) duct.
1. An Ø 8.0 mm hole is drilled through the duct and the EPP of
the HRV unit in the position shown on the diagram.
2. The sensor is secured to the ducting with two Ø3.0mm self-
tapping screws (must be suitable for the ducting material),
using the two holes in the ange on the sensor.
3. Apply a suitable sealant around the outside diameter of the
ange to seal around the duct.
4. The sensor position may need adjustment to ensure that
the temperature of the airow at the centre of the duct is
measured. See diagram for positioning dimensions.
