In the working area the operator is responsible to third parties. Responsibilities for the various activities on the air dehumidifiers must be clearly defined and observed. Unclear competences are a safety risk. The user must:  make the instruction manual accessible to the operator and  make sure that the operator has read and understood the instruction manual. Page 5 of 32 SAFETY Safety instructions The air dehumidifiers must not be used under the following conditions:  In rooms with potentially explosive atmospheres.  In rooms with aggressive atmospheres, e.g. ammonia, wood acids, chemicals, excessive chlorine content etc.  In rooms with water with a pH value outside the range from 7.0 to 7.4. In case of lower pH values there is risk of corrosion for all metals and risk of damage to mortar-containing materials (joints). Higher pH values cause skin and mucous membrane irritations and increased lime deposits.  In rooms with salt or liquids with a salt content > 1% (incl. brine baths).  In rooms with ozone-treated air.  In rooms with high solvent concentration.  In rooms with extreme dust load. Please note that excessive air movements in the room may impair the function of the air dehumidifier because they could disturb the air flow of the dehumidifier. In addition the following must be observed when using the air dehumidifier:  Work on electrical equipment may only be carried out by skilled electricians.  Original spare parts or spare parts approved by the manufacturer shall exclusively be used.  In the event of any malfunction the air dehumidifier must be switched off and secured against unintended restarting. Page 6 of 32 PERFORMANCE DESCRIPTION 3 Performance description You bought an air dehumidifier manufactured by AERIAL and thus decided for a well-proven product "Made in Germany". Designated use The air dehumidifiers are designed exclusively for dehumidifying air at atmospheric pressure in enclosed indoor rooms. The air dehumidifier can prevent the formation of condensation water, remove excessive humidity and keep humidity at a defined constant level. Operating the air dehumidifiers within the limits of designated use also involves observing the specified operating conditions (refer to page 15). Any use of the air dehumidifier not in conformity with or going beyond the designated use is considered contrary to its designated use and will result in the forfeiture of all warranty claims. The operating time of the air dehumidifier until drying of the room and the humidity to be reached depend largely on the ambient conditions in the room in which the air dehumidifier is installed.

The fan (Fig. 4, item 4) draws the moist air in through a cooling coil (evaporator) (Fig. 4, item 2). In the cooling coil the air is cooled so far below the dew point that the water steam of the air condenses and flows into the outlet or pump kit (option). The cooled and dried air is re-heated at the condenser (Fig. 4, item 3). Due to the heat pump effect the output air is a few degrees warmer than the room air drawn in. The resulting energy gain can reach 3 times the electrical energy consumption.

Page 14 of 32 TRANSPORT AND INSTALLATION Operating conditions Series AD 420 / 430 air dehumidifiers are intended for mobile or stationary use in closed rooms, on building sites, in water works, indoor swimming pools, garages and storage rooms. The series AD 420 / 430 air dehumidifiers work without problems in the temperature range from +3 °C to +32 °C and the humidity range from 40% to 95% relative humidity. Using the appliance in rooms with higher temperatures will cause damage to the compressor. Using the appliance in rooms with lower temperatures is inefficient and can result in icing. Storage of the air dehumidifier at impermissible temperature conditions can result in damage / problems in case of immediate switching-on. Therefore allow the air dehumidifier to adjust to the temperature before switching it on. The suitable location for the air dehumidifier features:  230 V / 50 Hz power outlet  Flat ground  Free space of 1 metre minimum in front of the air outlet lamellae and air filter, better more!  Air must constantly flow unimpeded through the ventilation port next to the operating panel. Select the location in a way to ensure optimum circulation of the dehumidifier air in your room. The air dehumidifier must be installed on a flat ground. By using a condensation dryer humidity values of 40 – 45% r. h. minimum can be reached. If lower values are required an adsorption dryer must be used. Contact your technical advisor. In case of doubts about the operating conditions your technical advisor can help you. Page 15 of 32 TRANSPORT AND INSTALLATION Electrical connection Danger to life due to electric shock DANGER  Prior to commissioning the technical data of the air dehumidifier must be compared with the conditions prevailing in the room of installation! The following items must be checked prior to electrical connection of the air dehumidifier:  Is the mains voltage in conformity with the voltage of the air dehumidifier?  Are socket and supply system sufficiently fused?  Has an RCCB been installed?  Is the appliance coupler suitable for the building socket outlet?  Is the socket outlet used grounded properly? 1. Connect the mains plug of the power cable with the socket outlet. Page 16 of 32 TRANSPORT AND INSTALLATION Connect condensate drain hose CAUTION Material damage / insufficient performance due to improper connection of condensate drain hose       Handle water collecting tank and condensate drain pipe with care. In case of use without water collecting tank: The rear hose end must be in a lower position than the front hose end (drain pipe): minimum slope 5%, i. e. 5 cm / metre. Do not immerse the hose end in water (water back-up may occur). Never bend the hose. Do not place any objects on the hose. Check regularly whether condensate is properly discharged. 1. Remove the water collecting tank from the rocker. 2. Attach the condensate drain hose to the condensate drain pipe (Fig. 2, item 3) and fix it with a hose clamp. 3. Lay the hose with a slope (min. 5%, i.e. 5 cm / per metre) from the air dehumidifier to an outlet. If the air dehumidifier is installed on a wall bracket or in any other elevated position, the hose can also be directed down through the hole in the rocker.

The air dehumidifier will switch off at a relative humidity of about 60% - 80% and switch on again when a humidity of 60% - 80% is exceeded. The air dehumidifier will switch off at a relative humidity of about 40% - 60% and switch on again when a humidity of 40% - 60% is exceeded. The air dehumidifier will switch off at a relative humidity of about 20% - 40% and switch on again when a humidity of 20% - 40% is exceeded. If very precise setting values are required, use a hygrometer with a precise humidity display to set the hygrostat. Page 21 of 32 OPERATION AND OPERATOR CONTROL Commissioning The air dehumidifier must have been properly installed and connected (refer to chapter 5, from page 12) before it can be commissioned. Before commissioning the air dehumidifier allow it to rest in its final position for about 15 minutes after transport. During this time, the oil distributed in the cooling system and churned up by transport will flow back to the compressor. This procedure will extend the service life of the compressor. 1. Connect the hot condition coupler of the power cable included in the delivery to the socket on the air dehumidifier. 2. Connect the power cable to the power outlet. 3. Ensure that the water tank is installed in the air dehumidifier or a drain hose (option) has been properly fitted and laid to a collecting vessel or an outlet. 4. Turn the hygrostat to position "I“ and switch the air dehumidifier on via the "On / Off switch" (Fig. 5, item 1). If the air dehumidifier has been correctly connected and the existing humidity is higher than the set humidity value the air dehumidifier will start to work. Operator control 1. Select the desired humidity on the hygrostat (Fig. 6) and switch the air dehumidifier on via the On / Off switch (Fig. 5, item 1). If the existing humidity is higher than the set value the air dehumidifier will start to work. If the existing humidity is lower than the set value the air dehumidifier will not start to work. The On / Off switch lights when the air dehumidifier is switched on. The fan can be operated at two speeds (Fig. 5, item 5). During operation condensate is produced. This condensate can either be fed directly to an outlet via the condensate drain hose or collected in the water tank. When the water tank is full, it will actuate the rocker by its weight and the air dehumidifier will switch off. The pilot lamp (Fig. 5, item 2) will light up. 2. Switch the On / Off switch on the air dehumidifier off and empty the water tank. After re-inserting the water tank into the air dehumidifier switch the air dehumidifier on again. Page 22 of 32 OPERATION AND OPERATOR CONTROL Automatic defrosting: During dehumidification ice may build up on the evaporator. The volume of ice depends on the ambient conditions in the room to be dehumidified. The series AD 420 / 430 air dehumidifiers are equipped with an automatic hotgas defrosting system. Depending on the extent of ice build-up, the air dehumidifiers will automatically be defrosted on demand according to the following principle:  A temperature sensor monitors the status in a critical area of the evaporator.  It transmits the defrost signal to the DryLogic electronics which will determine the defrosting demand and automatically start the defrost cycle. During the defrost cycle the compressor continues to run whereas the fan is stationary. After defrosting the air dehumidifier resumes work in the standard dehumidification mode. For living space, climate conditions of 20 – 25 °C and 50 – 60% r. h. are recommended. For quick building drying the hygrostat is set to continuous operation (item I). For drying and keeping rooms with wood furnishing (e.g. parquet flooring) or paintings, antiques etc. dry, a minimum moisture of 55 – 60% must be observed. In case of doubt please contact your technical advisor.

Page 25 of 32 TROUBLESHOOTING 8 Troubleshooting If problems arise with the dehumidifier please check the following points. Should the fault not be located please contact your technical advisor. WARNING Danger of injury by electric shock and risk of material damage Problem Air dehumidifier shows poor or no humidification performance. Page 26 of 32  The air dehumidifier may only be repaired by trained specialised staff. Within the warranty period, any work on the dehumidifier shall only be carried out by the manufacturer or persons commissioned by the manufacturer. Any work carried out by unauthorised persons shall lead to the forfeiture of all warranty claims! Possible cause The ambient humidity is lower than 40% r. h. or the ambient temperature is less than +3 °C. Under these conditions operation of the air dehumidifier is uneconomical. The air filter is severely soiled. The air flow is insufficient. In the long run, soiled filters can cause damage to the air dehumidifier. Compressor and/or fan motor are/is defective. Remedy Switch the air dehumidifier off. Tip: set the hygrostat to an achievable value (e.g. to about 50% r. h.) to ensure that the dehumidifier will switch off in time in respect of the ambient humidity. Clean or, if required, replace the filter. Tip: perform maintenance as described in chapter 7 at regular intervals! Use only original AERIAL air filters. Entrust a specialised company with the repair of the air dehumidifier. TROUBLESHOOTING Problem The fan of the air dehumidifier is out of operation, the compressor is working.

An ice block builds up. Possible cause Wrong ambient conditions or air dehumidifier defective. The humidity set on the hygrostat is not achieved or the air dehumidifier does not automatically switch off. Hygrostat set to a value < 45% r. h. The air dehumidifier is not sufficiently dimensioned for the application. There is a lot of humidity in the walls, the floor etc. Page 28 of 32 Remedy Place the air dehumidifier in a room with a minimum room temperature of +10 °C and wait until the ice has defrosted. Switch the air dehumidifier on and let it run for about 3 hours. Should a new ice block build up, please contact your specialised dealer. Make sure to operate the air dehumidifier in rooms with a minimum temperature of +3 °C. Problems may arise of the dehumidifier is immediately switched on after storage in colder environments. Depending on the ambient conditions your air dehumidifier can reach a minimum value of 40 – 45% r. h. Set the hygrostat to an achievable value (e.g. to about 50% r. h.) to ensure that the air dehumidifier will switch off in time. Room temperature, air exchange rate and open water surfaces, if any, are decisive for the humidity load of the room. Ask your specialised dealer to calculate the capacity required for your application. In this case the air dehumidifier will need some time to remove the water and achieve an acceptable value in the room.
