1. Remove machine from packaging.
2. Check both sides of wall, mark out apertures 'D' and 'E' in required location
and ensure they are level.
3. Cut out apertures 'D' and 'E' with due consideration to structure and safety
using a suitable lintel to bridge the gap.
4. Remove the four bolts holding the dehumidifier to the wall plate and also
the earth lead.
5. Locate the wall plate in apertures and ensure it is level. Drill and fix using
12 'C' holes and wall plugs /screws provided. Hole size 6mm (No 10) x
60mm.
6. Lift the dehumidifier on to wall and replace six M6 bolts ald wall plate earth
lead.
7. Fix supplied cavity bridging pieces and air inlet/outlet grilles, ensure all joints
are sealed with silicon caulking.

8. Electrical supply to the unit must be sized according to data on serial
number label paying special attention to I.E.E. regulations latest edition
regarding the special conditions governing electrical supply to machines in
potentially damp areas. The machine should be installed in accordance with
EMC2004/108/EC.
9. The electrical supply should be connected to the terminal block mounted
on the side of the bracket supporting the compressor. Brown/red to 'live',
blue/black to neutral and earth to the stud provided.
10. Fan mode switch can be set to cycle fan when humidistat senses demand
but should be set to continuous to promote good air circulation and reduce
condensation. Note that on models fitted with LPHW the fan(s) will start
automatically whenever there is an air heating demand. On 'X' models
fan(s) will stop during defrost cycle.
11. Locate pipe from drip tray and run away to waste, a short length of 10mm
pipe is provided which should be led into a fixed waste pipe (ensure an air
gap, tun dish).

machine as per diagram below:
13. It is recommended that isolating valves are fitted to enable isolation of the
machine in the event of service.
Complete water circuit as per diagrams overleaf.
(a) Circulating pump must be sized to take into account the design flow
rate of the machine plus the water system resistance. For Pressure drops
