TROUBLE-SHOOTING<br />
SERVICE<br />
1. Check both motor fuses - F 3 = 2.0 Amp & F 4 = 3.15 Amp<br />
2. Replace control box<br />
19.5 .....No Air - Motors Running -<br />
1. Check compressor control fuse - F 5 on control box =<br />
200mA.<br />
2. Check the mains supply to the compressor. The<br />
compressor start contactor is housed inside the rear<br />
electrical panel. Check across pins 1Ll and 5L3 which<br />
should be at mains supply voltage.<br />
3. Check that the pins in the connector inside the roof of the<br />
base unit are clean, and there are no signs of sparking, or<br />
replace as required.<br />
4. Unbolt the compressor and remove it from the machine.<br />
Inspect and replace the complete unit if necessary.<br />
19.6 .....Loss of Power when Starting Compressor<br />
1. Ensure that an extension cable is not being used causing a<br />
drop in voltage. Due to the relatively high current required<br />
to start the compressor, the mains cable supplied should<br />
not be extended in any way<br />
2. Check the main fuse in the plug or distribution board.<br />
3. Check the main isolator switch on the rear panel.<br />
4. Check filters are not clogged and change them frequently.<br />
Cleaning has only a short term effect.<br />
WARNING<br />
EXPENSIVE DAMAGE WILL OCCUR IF THE<br />
COMPRESSOR IS ALLOWED TO RUN WITHOUT ITS<br />
FILTERS.<br />
5. Check customers supply voltage and if necessary fit a<br />
Voltage Boosting Transformer of sufficient output level.<br />
