Frequently Asked Questions - DH 60 AX TROTEC

How does the DH 60 AX dehumidifier work?

The device uses the condensation principle. A fan draws moist room air through an evaporator, where it is cooled below the dew point, causing water vapor to condense. The condensed water is collected and drained via the condensation drain hose. The dry air is then reheated and expelled.

What are the recommended maintenance intervals?

Regular maintenance includes: before each start, check the condensate drain; every 2 weeks, clean the air filter and housing; every 4 weeks, visually inspect interior; every 6 months, check for damage and test run; annually, replace the air filter. See maintenance log in manual.

Why is no condensation forming?

Possible causes: the room humidity is below the set level, the air filter is dirty, the room temperature is outside the operating range, or the drain hose is blocked or kinked. Check the hygrostat setting and ensure proper drainage.

What should I do if the device is loud or vibrating?

Ensure the device is mounted horizontally on the wall. Check for loose screws or objects. If vibrations persist, inspect the internal components for dirt or damage. The sound pressure level is 54 dB(A) at 1 m.

Can I use an extension cord?

Only use extension cords that are suitable for the device's power consumption (1200 W) and are completely unrolled. Avoid electrical overload. For safety, the device should be connected directly or via a proper RCD.

How to clean the air filter?

Remove the air filter and clean it with a soft brush or by vacuuming. If heavily soiled, wash with mild detergent and water, then dry thoroughly before reinstalling. Replace the filter at least annually.

What is the maximum dehumidification capacity?

The DH 60 AX can remove up to 90 liters of moisture per 24 hours under optimal conditions (high temperature and humidity). Actual performance depends on room conditions.

What are the safety precautions?

Do not use in explosive atmospheres. Keep air inlets/outlets unobstructed. Never insert objects into the device. Disconnect power before maintenance. Use an RCD in wet areas. Only qualified personnel should perform electrical work.

How to adjust the humidity level?

Access the hygrostat control dial by removing the protective housing. Turn the dial to the desired relative humidity (e.g., 50-60% for living spaces). The device will automatically maintain that level.

What to do if the device does not start?

Check power supply (230 V/50 Hz), fuse, and power cable. Ensure the room humidity is above the selected setting on the hygrostat. If still not starting, contact a specialist or Trotec service.

Information about the device

Description of the device

This device uses the principle of condensation to automatically dehumidify rooms.

The fan sucks damp room air through the air inlet (3), the evaporator and to the condenser located behind it. The air is cooled at the cold evaporator until it is below the dew point. Water vapour contained in the room air precipitates on the evaporator fins as either condensation or frost. The dehumidified, cooled air is rewarmed at the condenser and blown out at a temperature of approx. 5 °C above room temperature. The drier air, thus conditioned, mixes with the air in the room via the air outlet (1). The humidity in the room where the device is positioned is reduced as air constantly circulates through the device. Depending on the air temperature and the relative humidity, the condensed water either drops continuously or only during the defrost phase into the condensation tray. The condensate is discharged from the device via a pre-assembled condensation drain hose (4).

To set the desired humidity level, a hygrostat with control dial (5) is provided in the device's interior. This control dial can be easily accessed once the protective housing (2) has been removed.

The device can reduce the relative humidity of a room by up to approx. 30 %. Because of the heat radiation which is tied up in operation, the room temperature can rise by approx. 1-3 °C.

Storage

When out of use, store the device as follows:

• d r y ,
  • with a roof overhead,
• in an upright position where it is protected from dust and direct sunlight,
• with a plastic cover to protect it from invasive dust, if necessary.
• The storage temperature is the same as the range given for the operating temperature in the chapter Technical Data.

Operation

• After being switched on, the device operates fully automatically.
• So that the built in sensor can correctly detect the relative humidity, the fan continues to operate until the device is switched off.
• Avoid open doors and windows.

Notes regarding the dehumidification performance

Dehumidification performance depends on:

• the spatial composition of the room
• the room temperature
• the relative humidity

The higher the room temperature and relative humidity, the higher the dehumidification performance.

For using in living rooms, a relative humidity of approx. 50-60 % is sufficient. In store rooms and archives, the humidity should not exceed approx. 50 %.

Positioning the condensation drain hose Note:

The condensation drain hose is already installed when the device is delivered.

1. Ensure that the condensation drain hose is properly connected to the device and is free of damage.

2. Depending on use, position the end of the condensation drain hose as follows:

- Position a sufficiently large container (at least 20 litres) beside the device and insert the hose end. Check the fill level of the container regularly.

– Position the end of the condensation drain hose above a water drain. For larger distances, a longer hose of the same type can also be used.

1. Ensure that the condensation drain hose always descends.

Switch device on

1. Ensure that the condensation drain hose has been laid and connected properly. Do not create tripping hazards.
2. Ensure that the condensation drain hose is not bent or jammed and that there are no objects on the condensation drain hose.
3. Ensure that the condensation can run off properly.
4. Only have an electrically skilled person connect the power cable!

Room humidity adjustment

Set the desired humidity level via the control dial (4) of the hygrostat.

Automatic defrost

If the room temperature is below 15\ °C , the evaporator becomes covered in frost during dehumidification. The device then carries out an automatic defrost. The duration of the defrost can vary.

Shut down procedure

1. Only have an electrically skilled person disconnect the power cable!
2. Remove the condensation drain hose and any residual fluid from it.
3. Clean the device, and especially the air filter, according to chapter Maintenance.
4. Store the device according to chapter Storage.
