1.1 Unpack the unit and visually inspect for any transport damage incurred after leaving our factory.
1.2 Depressurise the system before installation or maintenance is carried out!
1.3a Top inlet connection: If you choose to use the top inlet, locate a suitable condensate draining point in
your compressed air system and connect your drain as illustrated. The use of a ball valve is advisable.
1.3b Top inlet connection: Connect the outlet to an Oil/Water-Separator. We advise to use the nipple supplied
with your drain. If it is necessary to use an alternative nipple, make sure it is of the correct thread (1/4” BSP). Do
not over tighten!
1.4a Side inlet connection: If you choose to use the side inlet, locate a suitable condensate draining point in
your compressed air system and connect your drain as illustrated.
The use of a ball valve is advisable. The use of a venting line may be required.
1.4b Side inlet connection: Connect the outlet to an Oil/Water separator. We advise to use the nipple supplied
with your drain. If it is necessary to use an alternative nipple, make sure it is of the correct thread (1/4” BSP). Do
not over tighten!
1.5 Power cable connection: Unscrew the connector screw and remove the cap from the connector to connect
your power cable as illustrated. Replace the power connector, tighten the connector screw (Max. torque 1Nm)
and turn on the power supply. Make sure the gasket is secured properly to ensure IP65(NEMA4) rating.
- If your drain is pre-wired, go to step 1.6.
1.6 Slowly open the ball valve to restore normal system pressure.
1.7 Press and hold down the TEST button to check the valve function.
A purging sound must be heard.
1.8 Your drain is ready for operation!
Note: Clean the strainer periodically to avoid possible blocking causes by rust and/or debris.
Note: Check the valve function periodically. A purging sound must be heard.
