a)
b) Manually - The valve push button rotated to the right shuts off the drain permanently, until it is
rotated to the left when it can be pushed up to drain even when the unit is pressurised.
Ensure the regulator is correctly earthed using the marked wall bracket on the outlet side of
the unit as the earthing point as shown below and verify continuity from each Ball Valve (6) to
another known earth point. A resistance of less than 1 K ohms should be achieved for
dissipation of electrostatic charge. PRO AIR-2 shown.
Do not exceed the maximum working pressures and temperatures.
When regulating the pressure always adjust from a lower pressure increasing to the desired
pressure, rather than from a higher pressure down.
To lock the set pressure depress the knob which prevents it being adjusted. To release the
lock lift the knob up.
INSTALLATION
OPERATION
Do not install the unit above electrical or any other equipment that could be damaged by
discharged condensate oil.
Semi-Automatic - The valve push button is rotated to the left, in this mode when the air
pressure is exhausted from the unit the push button opens under spring operation.
The drain valve on the bottom of the filter and coalescer can be used manually or semi-
automatically.
Ensure air flows through the unit in the direction of the arrows on the body.
Install the unit as near as possible to the point of use.
An isolation valve is fitted (8) to the inlet of the PRO AIR 2 & 3 for convenience when
maintaining and to release condensate and oil from bowl. (see operation) Slide to the right
towards the regulator to open. Slide to the left to close.
The unit should be mounted in an upright position.
