2.0 INSTALLATION
2.1 Installing the Indicator
The unit must be installed away from any direct source of heat (e.g.
radiators) and areas where it would be subjected to steam or water
spray.
The mounting surface must be vibration free.
The unit is supplied complete with 10 metres of connecting cable with
plugs attached.
Fasteners for wall fixing are included in the package.
•Fix one end of the supplied 10m sensor connection cable to the
fans customer connection box (connection sockets marked NET).
•Select a suitable location for the sensor and arrange the cable
in position. Wire can be located behind a wall panel or fixed to
wall surface. Clearance aperture for wire should be approx 20mm
diameter to allow passage of plug end. Allow approximately 75mm
of the cable free at the mounting point to ease the connection of
the plug (Figure 1).
•Hold the base of the unit with one hand and the top half with the
other. Twist the upper half anti-clockwise to open the unit (Figure
2).
•Feed the cable through the hole of the lower half of the unit and
mark the locations of the fixing holes on the wall. There is a raised
line inside the base of the unit to aid alignment to the horizontal or
vertical (Figure 3).
•Fix the base of the unit to the wall using the fasteners provided, or
other suitable fasteners.
•Plug the cable into the socket of the PCB (Figure 4).
•Align the slots of the upper and lower halves of the unit and twist
the upper half clockwise to lock the 2 halves together (Figure 5).
