MAINTENANCE INSTRUCTIONS
These instructions are for cleaning the drain. If your drain requires servicing, i.e. replacement of wearing components, please refer to our dedicated service instructions (supplied with the service kit).
2.1 Stop the condensate supply, i.e. close the ball valve which is installed in front of the drain.
2.2 Press the TEST button to empty the drain of any residual condensate and to depressurise the drain.
2.3 Switch off the power supply and remove the power connector by unscrewing the connector screw. Make sure the display is off to check if the power supply is successfully disconnected.
2.4 Open the housing by unscrewing the four housing bolts using a 5mm Allen key and remove the top part from the reservoir.
2.5 Slide the electronics compartment up and unscrew the valve from the bottom part of the housing using a 23mm wrench.
WARNING: make sure the electronics compartment does not get wet, this will damage the unit!
2.6 Clean all valve parts thoroughly. Make sure there’s no debris left in the other parts of the drain.
2.7 Use a 10mm Allen key to remove the plug and strainer. Clean the strainer thoroughly. Replace the strainer and plug, using a 10mm Allen key.
2.8 Reassemble the valve inner parts and screw the valve back in to the bottom part of the housing, using a 23mm wrench (max. torque 10 Nm).
2.9 Close the housing by replacing the electronics compartment and top part on the reservoir and fixing the 4 housing bolts (max. torque 10 Nm).
Make sure the gaskets are secured properly to ensure IP65(NEMA4) rating and make sure the electronics have not been in contact with water.
WARNING: make sure the cable connected to the electronics compartment does not get damaged while re-assembling the components!
2.10 Replace the power connector, tighten the connector screw (max. torque 0,3 Nm) and turn on the power supply. Make sure the gasket is secured properly to ensure IP65(NEMA4) rating.
Make sure the display lights up to check if the power supply is successfully connected.
2.11 Slowly open the ball valve to restore the condensate supply.
2.12 Press and hold down the TEST button to check the valve function. Your drain is ready for operation! Check the drain periodically by pressing the TEST knob. A purging sound must be heard.
ALARM CYCLE
The alarm is triggered when the drain has to open too many times consecutively (20* without a pause), see section 1. The reason for the alarm may be debris (rust) particles blocking the valve inside the
drain, indicating a service interval is required. If the alarm has been activated, the drain will open for two times and run a diagnostic cycle, see section 2. After the alarm cycle, the alarm will be deactivated
automatically and the drain will return to its normal operation. If the reason for the alarm has not been solved, the drain will repeat the alarm cycle.
Depressurise the system before installation or
maintenance is carried out!
ALARM INSTALLATION INSTRUCTIONS
The drain is equipped with an alarm feature. The alarm feature can be connected to
an external alarm device with its own power supply.
1. Unscrew the connector screw and remove the cap from the alarm connector to connect the alarm cables to
the connector as shown below. Caution is required as you may be working with hazardous voltages!
2. Connect the cable to your alarm device, any device of your choice can be applied
i.e. a (flashing) light or alarm panel.
3. Connect your alarm device to a power supply. The
alarm switch type is a ‘contact output switch’. An
external power supply is required as the alarm
connection point on the drain works like a relay switch
only.
4. Connect the power supply to the drain alarm
connector to close the circle. Replace the
connector and tighten the connector screw (max.
torque 0,3 Nm). Make sure the gasket is secured
properly to ensure IP65(NEMA4) rating.
