INSTALLATION
POSITIONING:
Position the dehumidifier unit in the center of the room to be conditioned if at all possible.
However if a damp patch is particularly apparent the outlet grille should be pointed towards it if
possible.
This unit can also be used in a duct system where applicable, please see the diagrams on the
following pages which identify the overall sizes of the unit and also the mounting points.
NOTE: Both inlet grille and outlet grille of the dehumidifier unit must have clear space around
them and not be obstructed in anyway.
For correct installation and operation the unit inlet
and outlet must have a clearance of 0.5M from all adjacent surfaces and or structures.
Before connecting this unit to the relevant power supply the following must be carried out.
Selecting the correct fan speed – The PD120 has a low fan speed and a high fan speed and the
required speed must be chosen before installation. To select the correct fan speed firstly remove
the air outlet cover via the 10off M4 hex head bolts, then remove the electrical box cover via the
4off M4 hex head bolts. Once the electrical box cover is removed the supplied link wire must be
wired between either the ‘C’ and ‘L’ or the ‘C’ and ‘H’ terminals on the terminal block. This is
shown below.
Before the unit will switch on it must have a low voltage humidistat wired into it with the NC
contacts wired to the terminal block inside the electrical box as shown below.
