6.7 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 AD 550/650/580/680 is equipped with an automatic hot-gas defrosting. It

ensures that, depending on the extent of ice formation, the appliance will be

defrosted automatically according to the following principle:

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

evaporator.

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.

During defrosting the compressor works and the fan does not work

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

7. Operating conditions

AD-condensation dryers are suitable for the effort on construction sites, in

residential buildings, in swimming halls, in garages and storerooms. AD-

condensation dryers work problem-free at the temperature range of +3 to +32° C

and in the case of relative humidity from 40% to 95% r.h. .

The use in rooms with higher temperatures leads to disadvantages at the

compressor. The use in rooms with lower temperatures 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:

in rooms of potentially explosive atmosphere

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

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.

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

In rooms of air treated with ozone

in rooms featuring a high concentration of solvents

in rooms of an extremely high ratio of dust.

Please consider also, that extremely air movings around the dryer can annoy

or affect the function of the dryer as the air flow of the dryer can not flow as

planned.

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

Technical Department of Messrs. AERIAL or a specialized dealer.

Using an AD-air dryer under inadequate operating conditions will entail that

the warranty becomes null and void.
