SAFETY WARNINGS
Misuse
• Never exceed the recommended safe working pressure/temperature for any of the equipment used.
• Do not use paint solvents to clean the unit or filter element.
• The fitting of non- recommended or non- original accessories or spare parts may create hazardous
conditions.
• Do not install the unit above electrical or any other equipment that will be damaged by discharged
condensate.
• Before dismantling the equipment for cleaning or maintenance, all air pressures must be isolated and
released.
• When assembling an air pressure gauge to the unit DO NOT use a spanner, always tighten by hand.
The disposal of non-metallic materials must be carried out in an approved manner. Burning may
generate toxic fumes.
Installation / Operation
1. Always install the unit so that the air flows in the direction indicated by the arrows on the body.
2. Install the unit as near as possible to the point of use.
3. Always depressurise the unit before periodic maintenance and installation.
4. Ensure the earth lead is connected to an earth point and verify continuity from each ball valve (item
4) to another known earth point, a resistance of less than 1k ohm should be achieved for dissipation
of electrostatic charge.
5. An isolation valve is fitted (6) to the inlet of the unit to allow condensate to be drained and for ease of
maintenance. Slide to the right towards the regulator to open. Slide to the left to close.
6. When reducing the pressure, always turn the regulator below the required pressure and adjust
upwards. When assembling the pressure gauge to the unit always tighten by hand. DO NOT USE A
SPANNER.
7. To lock the regulator press the adjusting knob down . To release the lock lift the knob up.
8. The condensate drain valve on the bottom of the filter can be used semi-automatically or
manually.
a) With the push button in the central position the valve is semi-automatic (i.e. when the filter bowl is
depressurised the valve will open allowing the condensate to drain from the bowl). When the bowl is
pressurised the drain valve will automatically close.
b) If necessary, it is possible to drain the condensate while the filter bowl is pressurised. To do this,
the simple operation of pushing the valve up will open the drain and release the condensate.
c) By rotating the button clockwise, the valve becomes locked closed. Drainage is impossible in this
position and can only occur when the button is returned to the central position.
Note: To unscrew the bowl from the unit , use a compass key (pin spanner) with 2 mm diameter
pins.
Maintenance
Cleaning: The filter element can be cleaned or replaced by unscrewing the bowl and then the central tie-rod
It is recommended that filter/coalescer/activated carbon elements are replaced periodically i.e. when a drop
in pressure is noticeable through the unit or every 6 months.
Ensure earthing of the unit is not affected by maintenance activities , see installation above.
