If installing in position where condensation is likely to run backwards into the fan you will need to use a suitable
condensation trap or ensure the discharge ducting has a fall towards the external extract grille.
Orientation of the Unit:
The unit is designed to be screwed down to a robust impermeable surface horizontally, vertically, or inverted as shown
below.
The humidity sensor is located in the inlet identified below. This inlet must be used as the inlet from the wet
room. If this inlet is not used the sensitivity and reaction time to humid air may be reduced or not sensed.
DO NOT install this product in areas where the following may be present or occur:
Corrosive or flammable gases, liquids or vapours.
Ambient temperatures are higher than 50°C or less than -5°C
Possible obstructions which would hinder the access or removal of the fan.
This fan is rated to IPX2
Position of air inlet grilles:
As far as possible from and opposite to the main source of air replacement to ensure air flow across the room
(e.g. opposite an internal doorway).
Near the source of steam or odours.
Not where ambient temperatures are likely to exceed 50
ƒ
C, or above a cooker hob or eye level grille.
Ceiling Mounted
Horizontal position (Recommended)
In the vertical position the outlet
must face vertically upwards only

The Xplus2 EC RFH has infinite speed control, this will enable you to control the air flow of your Xplus2 EC RFH to
your specific systems requirements, while maximising the Xplus2 EC RFH’s energy efficiency.
Step 10 – Switch off the mains electrical supply and remove all fuses before commencing.
Step 11 – Identify the correct speed controller for the speed you wish to adjust.
Step 12 – Using a small long handled screwdriver, adjust the speed control as required by turning the controller head.
Turn clockwise to increase the speed and anti-clockwise to decrease the speed.
If the speed controls are turned fully anti clockwise the fan will not operate!
Step 13 - Refit the electrical termination cover by replacing the 3 captive screws removed in step 2.
Step 14 - Connect the cable from the isolating switch to the electrical supply wiring
Step 15 - Refit fuse before turning on the electrical supply.
To prevent interference between other RF systems the fan and RF switch need to be ‘paired’ together.
Step 16 – Locate the ‘Pairing Switch’
Step 17 - Press the ‘pairing’ switch to activate.
Step 18 - Take the RF switch and operate adjacent to the fan. Once the fan operates, switch and fan are ‘paired’
Step 19 - There is a 2 minute period after the switch is activated, when pairing can take place. If this time period is
exceeded the switch will need to be re-activated. This time limit is to prevent erroneous ‘pairing’ with other RF
switches that are not intended for use with this product.
