

Adjust the temperature supply and return set points (if necessary, via the chosen
control management scheme) to call for 100% cooling (refer to the

Controls

section).



Ensure all KNOBS and SWITCHES are adjusted to suit the design requirements
(refer to the

Controls

section).

To switch the unit ON

, use the microprocessor keypad as follows:

Press

Prg

, press

& finally

CAUTION

There will always be a delay between the enabling of the unit and the energising of
the compressor contactors, anything between 1 to 2 minutes. Be patient.



Check that each circuit trips on low pressure. The alarm should appear within
3 minutes.



The alarm will be recognised at the display circuit trip, to clear the alarms refer
to
