4. Appropriate use
TD420M series condensate drain is intended exclusively for the following purpose:
Draining condensate from compressed air system (air compressors, air receivers/pressure
vessels, air dryers and air filters).
Any other form of use or one going beyond this shall be considered as inappropriate. We shall have
no liability whatsoever for any damage incurred as a result.
5. Installation
Warning due to a sudden release of pressure!
High pressure could be dangerous and hazardous to the operator.
Before installing the device, check that the system is not under
pressure. Wear necessary personal protective equipment and keep
follow the safety rules when working with pressure equipment.
Condensate drainer can be assembled in many
ways. However, you must follow the arrows on
valves from inlet pointing to the outlet. You have
to screw the parts together. The bottle in the
picture left indicates where you have to use the
seal, such as Loctite 542. On other joints you can
also use a seal, although friction sealing will be
enough (well tighten the joints).

Connecting several condensate collecting points to one condensate drain device causes operating
problems (1). Make sure that each condensate collecting point has its own condensate drain (2).
After installation or maintenance, the test button should be pressed to empty condensate that has
been collected while the ball valve has been closed.
5.1Installation instructions
When you install device follow this instructions.
1. First step is to connect a nipple (1) and high-pressure valve (2). For sealing you can use a
seal, such as Loctite 542. You must follow the arrows on valves from inlet pointing to the
outlet.
2. Next step is to connect high pressure valve (2) with elbow (3). See picture on page 7. There
can also use a seal. You must follow the arrows on valves from inlet pointing to the outlet.
3. Then is needed to connect a second nipple (1) with elbow (3). There is not need a seal,
because sealing is guaranteed with coned 60°. An assembly is made with fittings and
pressure valve.
4. We need to connect this assembly with electromagnetic valve (4). There you can also use a
seal, such as Loctite 542. You must follow the arrows on electromagnetic valves from inlet
pointing to the outlet.
5. Next step is to use a connector gasket (5) and put this on the electromagnetic valve (4). And
then we can put timer (6) on the connectors of electromagnetic valve (4).
6. The end step is to connect an electric cable with timer. See instructions in chapter electrical
installation.
7. This assembly you can mount on the filter housing.

Danger due electrical voltage!
Electric could be dangerous and hazardous to the operator.
Be careful not to pinch wires by cover! Be careful to clamp all strains of wires into respective terminal
blocks (use ferrules)!
Electrical connection should be made as shown above. It depends on orientation of the cover.
6. Storage information
The following storage must be considered for proper operation:
Store the components and elements indoors in a dry place.
Store them in original packing until they are used.

7. Operation
For operation with TD420m follow next steps.
1. Connect condensate drain device with the filter housing. You must follow the arrows on
pressure valves and electromagnetic valves from inlet pointing to the outlet.
2. Connect outlet of the condensate drain to outflow.
3. Full open a high-pressure valve. High pressure valve must be open full all time, if we want
that device operate correct. For more, see chapter Inlet valve.
4. Connect a condensate drain device to the electric network.
5. Set time Ton and Tof. Instruction for this you can find below and in chapter Approximate
calculation of discharge capacity
6. Make a test by pressing a test button.
1 –Inlet from compressed air system to
condensate drain
2 –Outlet from condensate drain to
condensate collecting pipeline
Condensate drain consists of two timers, Ton and Toff. The Ton timer regulates the time duration of
discharging. The Toff timer regulates period between two discharges. At the moment, when the
device is connected to mains power supply, it activates the discharging process, which is noticed by
the sound of valve being open. Condensed water flows through inlet connection 1 and is discharged
through valve and outlet connection 2. After the set time Ton passes, the valve closes and green LED
light is turned on until the time Toff passes, when new cycle begins. Cycles repeats continuously.
The time between discharges Toff can be set from 1/2 to 45 minutes.
The time of discharge Ton can be set from 1/2 to 10 seconds.
For right settings refer to chapter Approximate calculation of discharge capacity

11
P Periods Ton and Toff are set by knobs on the
condensate drain device.
After some weeks of operation, when you check
electromagnetic valve test, you can may adjust
the periods, if notice that only air is discharged
when the test button is pressed, then the Toff
may be increased. On the other hand, if a lot of
condensate is discharged every time, we press
the test button then the Toff must be shortened.
Made this test shortly before draining.
Be aware that amount of condensate is higher in
summer and when compressed air consumption
is increased.
By pressing TEST button valve opens for Ton.
The green LED lights on during off period. But
during discharging, it is switched off.
7.1Inlet valve
The function of inlet valve is that you can make a service on condensate service or that you can
replace it. Inlet valve must be full open during operation.
Risk of material damaged!
Inadequate condensate drain intervals lead to the flooding of the filter and damage the downstream
pressure devices.

7.3Troubleshooting
If having a trouble with condensate drain device:
1. Test the device with pressing test button. Try several times.
2. If it not better and the device not draining water or air, disassemble and clean the valve and
fittings.
3. Check time Ton and Tof.
4. Check the electrical installation, if all contact are connected.
5. Replace timer or electromagnetic valve. For this change contact us or your local dealer.
8. Maintenance
Service:
Sealing elements are subject to wear, which depends on various operating parameters such as
pressure, temperature, dirt content, etc.
Warning due to a sudden release of pressure!
Pressure could be dangerous and hazardous to the operator.
Depressurize the filter before carrying out any work on the filter.
Never remove any parts of the filter, when the filter is still pressurized!
Before beginning maintenance work follow these steps:
1. Close ball valve
2. Depressurize the unit (push test button)
3. Cut off the power supply
Once per week make a visual check of the fittings and valve with timer controller. Next to a visual
check we must do timer and electromagnetic valve test by pressing the test button on timer
controller. If necessary disassemble and clean the valve and fittings.
After installation or maintenance (testing the settings, tightness or any other work), the test button
should be pressed to empty condensate that has been collected while the ball valve has been closed.
