5 General description General This product is designed for outdoor location and is intended for refrigerants that are not aggressive in contact with copper. The product is provided with axial fans and the casing is made of aluminium sheeting as standard. Important Do not allow the product to be covered by foreign objects when in operation. Unobstructed circulation of air is necessary to achieve the highest cooling efficiency. The laminar surfaces of the coil must be free of deposits Item Designation Item Designation Item Designation 1 Cooling coil 4 Connecting pipe 7 Junction box 2 Leg 5 * Air vent. 8 Fan guard grill 3 * Drain 6 Axial fan 9 Safety switch *= Applies to Dry Cooler 5

7 Receiving and fitting The product is subjected to thorough inspection of quality and function before leaving the factory. If faults or damage due to transportation are detected on the product, the transporter and point of sale is to be contacted without delay. Assembly 1. Move the product to the place of installation before removing the packing. The cooler is provided with eyebolts (A) and shall only be lifted using these according to instructions on the cooler and the directions for use. 2. The legs on are mounted in the transport mode during transportation. These are to be fitted for installation in the two upper pairs of holes on the outermost part. A 3. Bolt the product through the pre-drilled mounting holes to a firm base. 7

8 Installation The following instructions should be read together with the technical leaflet. Location Place the product so that air can pass freely over the entire coil surface and if possible so that the wind direction does not affect the evacuation air because re-circulation could otherwise occur. This applies particularly to models that have low revs. The product is to be mounted on a firm base and secured with foundation bolts. The frame of the product is provided with pre-drilled holes. >Y >2xY Y >Y >2xY Y Y 8

10 Installation 1 Tube installation for Condensor The product is to be filled with the amount and type of refrigerant stated by the installation engineer. The connecting tubes are located on one end of the unit. The hot-gas inlet is connected to tube (1). The liquid outlet is connected to tube (2). 2 Tube installation for Dry Cooler The product is to be filled with the amount and type of heat transfer medium stated by the installation engineer. The connecting tubes are located on one end of the unit. 1 2 The air vent is at the highest point of the manifold tube (1). The incoming lead is connected to tube (2). The return lead is connected to tube (3). The drain (4) is located at the bottom of the manifold tube

11 Installation Installations may only be made by authorised persons and in accordance with national standards. The cooler may not be connected to other voltage or frequency than its rated data. 2 1 Connecting the fan To be connected to the safety switch as follows: Loosen the screws (1) with a screwdriver and remove the cover (2). Connect the cable through the screw fitting (3) on the side of the cover. N.B. Ensure that the fan rotates in the direction indicated by the arrow. 3 Setting the motor protector The maximum current valu e at -30ºC is indicated on the rating plate. Refer to the diagram for dimensioning of over-current protection at other ambient temperature. The overcurrent protection should have an adjustment range of +/- 20%. I C 11

13 Preventive maintenance Warning. Make certain that the power supply is disconnected. 3 Changing the fan Disconnect the electric terminals in the junction box for the fan (1). Remove the bolts (2) (4 off) and washers and take off the fan (3). 2 1 Mounting the fan Fit the bolts (2) and washers in the four holes. Observe that there is a tagged washer between the casing and the fan grille. Upright model Fit the bolts (2) and washers loosely in the two upper holes. Then fit the lower bolts and tighten them. Standstill During long periods when the unit is not in operation the fans should be run at least twice a month. They are to be run until the motor reaches normal working temperature, ie, about 15 minutes. 13

14 Preventive maintenance Warning. Make certain that the power supply is disconnected. Cleaning the cooling battery 1. Cooling batteries that are lightly soiled can be cleaned by brushing and blowing with compressed air. 2. Then wash the battery with water and environment-friendly detergent that does not corrode aluminium or copper. Ammoniac may not be used. 3. Rinse and allow to dry. Caution Always wear protective gloves when cleaning or when in contact with the batteries. 14
