Dry air hose
Insert the nipple in the dry air hose and tighten with a hose clamp. Press the nipple in the dry air
duct. Install the other end of the hose on the dry air connector on the dehumidifier using a hose
clamp.
Control unit
Homevision® control unit must be installed at approximately half the height of the crawl space in a
location that is not directly affected by dry air or radiation from hot or cold surfaces, so that the
measured temperature and humidity values are as accurate as possible.
Screw the holder into the sub-floor, the roof of the crawl space, and slide down the control unit with
cable and sensors. Connect the control unit cable to the dehumidifier. For further information about
Homevision®, see its manual.
Damper settings
CTR 300TT2 is equipped with dampers, both for wet air and dry air, which together give the
possibility of regulating wet air volumes and thereby the negative pressure in the crawl space. Wet
air damper positions are marked 1 and 2 and dry air damper positions are marked A and B.
• In normal spaces, setting 1A is used.
• In the event of strong odour, 2A until the odour has gone and then 1A.
• For radon 2B.
See Radon and odour problems, under pressure control on the next page for more information.
Electrical cable
The dehumidifier is connected, when the installation work is completed, to an earthed single phase
socket, 230VAC, 50 hz, with maximum 16A fuse. The socket that is used is recommended to be
protected by a earth-fault breaker.
