Condair UDC - Mounting Location; Installation in the Duct

109Condair MHD
8.4 Mounting location
Mounting in the supply air duct: Mount the Condair MHD in the supply air duct at least 3 meters
downstream from the nearest fan and coil and with a minimum distance of 5x the humidication distance
to the steam distributor (see manual of the humidier).
Mounting in a room: For applications with high requirements for IP protection, the Condair MHD can
be used as a room humidistat. Use the wall bracket included in the delivery and place the Condair MHD
at least 1.5 m above the oor in a protected location on the wall.
Observe the following placement notes
– Do not place the Condair MHD in niches, behind curtains, etc.
– Do not place the Condair MHD near heat sources, within the area with direct air draft or direct sun-
light.
8.5 Installation in the duct
1. At the place of location drill a hole with a diameter of 22 mm (0.87") as well as 2 holes for the self
tapping screws into the duct.
2. Loosen the two screws on the housing cover and remove cover.
3. Lead connecting cable through the cable gland and connect wires to the terminals according to the
wiring diagram. Reattach the housing cover and secure it with the two screws.
4. Align the duct ange concentrically with the hole and fasten it to the duct with the self-tapping screws.
5. Push the sensor probe through the duct ange into the duct. Determine the insertion depth and x
it with the screw in the duct ange.
