5.7 Condensate outlet AD 740 / AD 750

The dehumidifiers AD 740 / AD 750 are provided with a water collecting bucket (12 l)

and a connection for hose 15 mm.

The water bucket is in the device on a balance. The balance is activated by the

weight of the full bucket and the device is switched off. Switch off the unit at the

on/off-switch and empty the bucket. After the bucket is placed in the device again,

turn on the device at the on-/off-switch.

A connection outlet 15 mm is placed above the bucket. Remove the bucket

provided that you would like to guide the condensate directly into a drain. Attach a

hose to the drain 15 mm and secure this with a hose clamp. Proceed cautiously in

order not to burst the drain from the condensate tub.

Guide the hose with slope of the device into the drain away (at least 5 cm per

meters slope).

5.8 Condensate outlet AD 770 / AD 790

The air dryer AD 770 / 790 are serially equipped with fitting for 15 mm hoses. As an

accessory, a water tank (25 ltr., optional extra) is available which is put under the

device at the back. A piece of hose which is led into this bucket is already mounted.

ATTENTION:

Make sure that the condensate can always be handled safely.

The water tank at AD 770 / 790 (optional extra) does NOT disconnect the device in

the case of full state. During unattended using, AD 770 / 790 with built-in pump is

advisable.

5.9 Condensate pump (optional)

Optional the devices are available with built-in condensate pump. In that case, a

connection piece is found at the back wall of the device for hose 12 mm.

A red pushbutton is also found at the back wall. In this way, the pump can be

emptied manually, for example before transportation of the device.

We recommend the manual pumping out before transportation since otherwise

water from the pump can run onto the ground while tilting the device.

During air drying, ice may form at the evaporator. The volume of ice depends on the

ambient conditions prevailing in the room to be dried. The air dryer is equipped with

an automatic hot-gas defroster. It ensures that, depending on the extent of ice

formation, the appliance will be defrosted automatically according to the following

principle:

Ø A temperature sensor measures the condition existing in a critical area of the

evaporator.

Ø It transmits the signal for defrosting to the DryLogic-electronic. The DryLogic

finds out if defrosting is necessary, and it will start defrost-mode on its own.

Ø During defrosting the compressor works and the fan does not work.

When the ice is defrosted, the dehumidifier will start again with dehumidifying.
