ELECTRICAL CONNECTIONS

ISOLATE ELECTRICAL SUPPLY BEFORE 

ATTEMPTING SERVICE WORK.

A 230V, 50Hz, single phase supply is required.  Wiring 
must be installed by a qualified electrician and conform 
to current local and national regulations.

1.

Wire mains to unit via a double pole isolating switch, 
fused to IEE regulation.  Refer to diagrams indicating 
electrical wiring details.

2.

The electrical connection is via a 2m flying lead with 
factory fitted connector into socket on control box 
where an electric heater is NOT fitted.  If an electric 
heater is fitted, to connect mains supply to unit, 
slacken off the screw holding the control box front 
cover.  Carefully pivot the cover to support it, making 
sure the wires connecting the cover to the unit are not 
strained.   Connect the mains lead via grommet hole 
in the side panel to the LIVE, NEUTRAL and EARTH 
positions on the 12-way terminal block.  Replace 
cover and tighten screw.   

3.

If a Condensate Lift Pump is specified, this  w i l l   b e  
pre-wired back to the control box, but the pump 
assembly will be taped to the unit and must be fixed to 
the end of the drip tray before installing the unit, using 
the screws supplied.

4.

The fan motors are of the permanent split capacitor 
type and have a capacitor fixed to the outside of the 
motor.  All motors have thermal overload protection 
as standard.  Access to the fan tray is via removable 
panels on the bottom face of the unit.

CONTROLS

All units are fitted as standard with an ON/OFF switch and 
a FAN SPEED selector switch for three speeds.

When specified, the water control valves will have a 
controller that will be fitted to the exterior of the control 
box.

These are all fitted into the control box and pre-wired.

1. Fan Speed

Out of 6 speeds available, SL (Super Low), EL(Extra Low), 
L(Low), ML(Med/Low), M(Med), and H(High), the fan 
speed selector switch will be wired for three speeds. 
Speed adjustment and fine tuning is achieved by 
following the instructions indicated on the label that is 
positioned on the underside of the unit, adjacent to the 
control box.  

Each model size has its specific settings, examples as 
detailed on page 5   of this document.

An example of adjusting the speed setting is described 
below:-

E.g.:

If unit is selected for Medium/Low (ML) speed, 

then the speed selector switch is set at position II and 
other positions L and M, as below:

Position I

=

L (Low Speed)

Position II

=

ML(Med/LowSpeed)

Position III

=

M (Medium Speed)

If selected speed is EL then this would be Position II with 
SL and L other positions. If selected speed is H then this 
would be posiition III with M and ML other positions.
