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 (2), the air

filter (9), the evaporator and 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 which is prepared in this way mixes with the air in the room.

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 condensation is fed

through a pressure-resistant pipe connection and out of the

device by a condensate pump. To do so, a condensation drain

hose is connected to the hose connector (6) and the condensation

is diverted.

The device has a control panel (1) for operating and controlling

the functions.

Because of the heat radiation which is tied up in operation, the

room temperature can rise by approx. 1 to 3 °C.

Note!

The condensate pump is fitted with a float switch. It completely

switches off the condenser dryer when a critical filling level is

reached in the condensation tank (emergency shut-off). A beep is

emitted and the condensation tank indicator light (4) is lit. After

troubleshooting, the condenser dryer must be switched back on

by hand.

Safety

5Operating manual — Condenser dryer DH 145 S EN

Always transport the device with the help of another person. To

lift the device, use a fork lift or an elevating truck.

Before transporting the device, proceed as follows:

1. Wait until the condensate pump stops pumping condensate.

2. Press the power button (11) to switch off the device.

3. Press the push switch for draining the condensation tank (3)

to drain the condensation tank.

4. Remove the mains plug from the mains socket. Do not use

the power cable to drag the device!

5. Detach the condensation drain hose and drain it.

After transporting the device, proceed as follows:

1. Set the device in an upright position after transport.

2. Wait one hour before switching the device on!

Storage

When out of use, store the device as follows:

•Dry,

• Under roof,

• 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.

• After being switched on, the device operates fully

automatically.

• The fan runs permanently until the set nominal value is

reached or the device switched off.

• Avoid open doors and windows.

Positioning

When positioning the device, observe the minimum distance from

walls or other objects as described in chapter Technical data.

• Set the device in a level and stable position.

• When positioning the device, keep a sufficient distance away

from sources of heat.

• When positioning the device, particularly in wet areas, secure

it locally with an RCD (residual current device) which

complies with the respective regulations.

• Ensure that extension cords are completely unrolled.

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

greater the dehumidification performance.

For use in living rooms, a relative humidity of approx. 50 to 60 %

is sufficient. In store rooms and archives, the humidity should not

exceed approx. 50 %.

Continuous operation mode

In continuous operation mode, the device continuously

dehumidifies the air — depending on the humidity, until

switch-off or until the programmed switch-off time.

To start continuous operation, set a humidity nominal value

<30%.

Setting the timer

There are two ways to use the timer:

• The device switches on automatically after a specified

operating time.

• The devices switches off automatically after a specified

operating time.

Proceed as follows if the device shall automatically switch on

after a set time:

1. Press the timer button (12) once.

2. Adjust the time until automatic switch-on in steps of one hour

using the plus (14) and minus (13) button.

3. Press the timer button again to program the automatic

switch-off time. Press again to exit the menu.

4. Press the power button (11) to switch over to automatic

mode.

5. After the set time, the device switches on. It runs until the set

time until switch-off is up or until the device is manually

switched off.

Proceed as follows if the device shall automatically switch off

after a set time:

1. Press the timer button (12) twice.

2. Adjust the time until automatic switch-off in steps of one hour

using the plus (14) and minus (13) button.

3. Press the timer button (12) again to exit the timer settings.

Automatic defrost

At low ambient temperatures, ice may form at the evaporator

during dehumidification. The device then carries out an automatic

defrost. The duration of the defrost can vary.

Do not turn off the device during the automatic defrost. Do not

remove the mains plug from the mains socket.

Memory function

During short power failures, the device memorises the

programmed nominal value for relative humidity.

Programmed start and stop times for the automatic mode are not

memorised.

Shutdown

1. Press the power button (11).

2. Press the push switch for draining the condensation tank (3).

3. Do not touch the mains plug with wet or damp hands.

4. Remove the mains plug from the mains socket.

5. Remove the condensation drain hose and any residual fluid

from it.

6. Clean the device, and especially the air filter, as described in

chapter Maintenance.

7. Store the device according to chapter Storage.

9Operating manual — Condenser dryer DH 145 S EN

The accurate functionality of the device was tested during

production a number of times. However, if functionality faults do

occur, then check the device according to the following list.

Note!

The device is provided with a safety timer. Switch-on and

switch-off can be up to 3 minutes delayed.

The device does not start:

• Check the power connection.

• Check the mains plug for damages.

• If the fault indicator for the condensate pump lights up or a

beep is emitted, have the error repaired by a specialist

company for cooling and air-conditioning or by Trotec.

• Have the electrics checked by a specialist company for

cooling and air-conditioning or by Trotec.

The device runs but forms no condensation:

• Check the condensation drain hose is positioned correctly.

• Check that the condensate pump functions properly. Check

for abnormal vibrations and sounds. Remove external dirt.

• Check the room temperature. Check the device's permissible

operating range complies with the technical data.

• Ensure that the relative humidity complies with the technical

data.

• Check that the selected relative humidity is realistic. Relative

humidity in the room where the device is positioned shall be

at least 3 % above the nominal value. If necessary, reduce

the set relative humidity.

• Check the air filter is not dirty. If necessary, clean or replace

the air filter.

• From the outside, check the condenser and the condensate

pump are not dirty (see Maintenance chapter). If the inside of

the device is dirty, have it cleaned by a specialist company for

cooling and air-conditioning or by Trotec.

The device is loud or vibrates; condensate is leaking:

• Check whether the device is standing upright and on an even

surface.

The device gets very warm, is loud or is losing performance:

• Check the air inlets and air filter are not dirty. Remove

external dirt.

• From the outside, check the inside of the device and

especially the fan, the fan housing, the evaporator, the

condenser and the condensate pump for dirt (see

Maintenance chapter). If the inside of the device is dirty, have

it cleaned by a specialist company for cooling and

air-conditioning or by Trotec.
