1.General advice You have bought an air dryer made by AERIAL thus deciding for a proven quality product. If there are any questions, you will find some advice in this manual how to eliminate such difficulties as quickly as possible. ATTENTION: Immediately after receipt, you should check your air dryer for transport damage! In the case of damage, you should inform the forwarding agent, parcel service, post office etc.
3. Safety The condensation dryers DH 18 are furnished with protective devices. The devices were subjected to a safety examination. Dangers threaten in the case of operating error or abuse - for the user. - for the machine and other real values. - for the efficient work of the machine. All persons who have to do with the installation, service and maintenance of the devices must be qualified correspondingly and consider this operating manual precisely.
Responsibilities for different activities on the device must of course be determined and kept. Unclear competences are a safety hazard. The operator must make the operating instruction available for the user and make sure that the user did understand the manual. 4.Installation and transport The DH18-series is planned for the stationary and mobile effort.
5.2 electrical connection Before connecting the air dryer, the following items must be checked: Ø Does the mains voltage coincide with the voltage of the appliance? Ø Adequate fusing of socket and supply system? Ø Has the required residual-current-operated circuitbreaker (r.c.c.
Ø Check whether the bucket is placed in the unit or a drain hose has been fastened and laid appropriately.(refer to 5.7) Ø Set the required humidity value at the hygrostat (refer to 5.5). Ø If the existing humidity is higher than the set value, the air dryer will start to operate. If the existing humidity is lower than the set value, the air dryer will not start to operate. Ø The fan starts first and the compressor will start after approx. 3 Minutes. 5.
Pos. 0 = switched off Pos. 1 = continuous working > 90 - 80% = The dehumidifier switches off when a humidity between 80% and >90% r.h. has achieved. And switches on again when humidity is higher than 80%.... > 90% r.h.. 80 - 70% = The dehumidifier switches off when a humidity between 70% and 80% r.h. has achieved. And switches on again when humidity is higher than 70%.... 80% r.h.. 70 - 60% = The dehumidifier switches off when a humidity between 60% and 70% r.h. has achieved.
5.7 Condensate outlet The dehumidifiers DH 18 are provided with water collecting bucket (4 ltr) and connection for hose 12 mm. The water tank (refer to 5.1 – Pos. 4) is placed below the air inlet grit (Abs. 5.1 – Pos. 3). By a float mechanism the dryer swiches off automatically when the tank is full. The red neon lights up. To remove the tank, seize with both hands into the lateral case hollows and pull the tank forward from the dryer.
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.
7.Technical data Among other things, many different components which are installed in the condensation dryer decide on the capacity of the device. Since these components can never be completely identical, in accordance to DIN EN 810 the capacity may deviate up to 5% of specified capacity. Generell: Operational range: Protection class: Voltage: Air volume: Power consumption: Noise level: refrigerant: capacity: +15°C up to + 32°C / 40% r.h. up to 95% r.h. IP X0 230 V / 50 Hz 160 cbm/h max.
9.Trouble shooting Assign that dehumidifier a putative defect on, please, first check the following points. If this should provide no relief, please contact your technical consultant. 1)The dehumidifier shows a bad or no drying capacity - The humidity is lower than 40% r.h. or the temperature in that room is lower than +15°C. The using of the dryer is uneconomical in the case of these conditions. It is recommended to disconnect the dryer. Tipp: Put the built-in hygrostat (refer to 5.
