2. Locate bracket on wall in required position. Drill hole Ø 6.0mm (no. 10) by 60mm
deep as shown at 'A'. Insert wall plug and screw bracket in place.
3. Set bracket level with spirit level 'D' as shown, drill through and fix it at 'B' with wall
plug and screw.
4. Ensure bracket still level, tighten screws 'A' and 'B', finally drill and fix as above at
position(s) 'C'.

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 (if fitted) 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 it away to waste. A short length of 10mm pipe is
provided which should be led into a fixed waste pipe. Two pipe outlet holes are
provided, one to rear of unit, one below the unit.

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.

Remove cover to gain access to manual reset thermostat.
19. Replace front cover, turn on electrical supply and turn humidistat
towards 'drier'. (Unless remote humidistat fitted, see note 16 above)
unit fan will start, followed 6 minutes later by the compressor.
20. It is recommended that the fan mode switch is set to continuous, as in
cycle mode the fan and heaters only run together if there is a demand
for dehumidification.
