5.8 Automatic defrosting

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 air-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 If a temperature of -1°C has been measured for at least 5 minutes, it passes a

signal on to the defrost-system. During the defrost mode the fan keeps running,

the compressor stands still. The ice on the evaporator is defrosted with the help

of the ambient air. Depending upon ambient temperature this takes more or less

time. After conclusion of the defrost mode (at the latest after 10 minutes) the

dryer begins to work again in the normal dehumidifying mode.

DH-condensation dryers are suitable for the effort in heated residential buildings,

garages and storerooms. DH-condensation dryers work problem-free at the

temperature range of +15 to +32°C and in the case of relative humidity from 40% to

95% r.h. .

The use in rooms with higher temperatures (> +32°C) leads to disadvantages at the

compressor. The use in rooms with lower temperatures (< +15°C) is ineffective and

can lead to icing.

Also the storage of the dehumidifier at inadmissible temperature conditions can lead

to damages / problems while immediate switch-on. Therefore, make possible short

time for adaptation for the device before switch-on.

ATTENTION:

The appliance must not be used under the following conditions:

Ø in rooms of potentially explosive atmosphere

Ø in rooms of aggressive atmospheres, for example ammonia and wood acid

Ø In rooms with water which shows a pH-value outside of 7,0 to 7,4. Remark: In

The case of lower pH-value, corrosion occurs at all metals and damages occurs

at mortar containing materials. In the case of higher pH-value, it comes to irritation

of skin and eye mucous membrane and extreme lime deposits.

Ø In rooms with salt or salty liquids. Salt content >1% (also sole baths).

Ø In rooms of air treated with ozone

Ø in rooms featuring a high concentration of solvents

Ø in rooms of an extremely high ratio of dust.

In the case of doubtful operating conditions it is recommended to contact the

Technical Department of Messrs. AERIAL or a specialized dealer.

Using a DH-air dryer under inadequate operating conditions will entail that the

warranty becomes null and void.
