Refrigerants contain hydrofluorocarbons (HFC’s). Glycol/water mix is used during manufacture but drained before delivery. The quantities in use are minimal but care should be taken in disposal. We trust that this information is sufficient but should you require further information regarding our products or maintenance service, please contact our sales department.” Machine Card In order to comply with BS EN 378-2:2000 “Refrigeration Systems and Heat Pumps – Safety and Environmental Requirements”, an adequately protected card shall be situated near the operating site and must be clearly readable. The card shall at least contain the following information: 1) Name, address and telephone number of the installer, his service department, or the person responsible for the refrigeration and the addresses and telephone numbers of the Fire Department, Police, Hospitals and Burns Centres 2) The refrigerant is R134a or R407C (refer to Technical Data Table) 3) To shut down the Compressed Air Dryer in an emergency, switch off the unit using the ON/OFF isolating switch on the front panel. The mains supply to the Dryer should be isolated at the mains isolator. 4) Maximum Allowable Pressures Compressed Air 13 barg 5) Flammability Limits in Air NONE General Safety Instructions IMPORTANT: THE FOLLOWING SAFETY PRECAUTIONS MUST BE READ AND UNDERSTOOD BEFORE REPAIR OR MAINTENANCE WORK IS ATTEMPTED. General . Beware of the following danger areas within the dryer : a) Any rotating components (fan etc.) b) Sharp edges (coil fins, etc.) c) Hot refrigeration pipework d) Possible live electrical components or terminals . The refrigeration and compressed air circuits can operate at high pressures and unauthorised tampering may cause injury or damage. . Discharge from the condensate drain will contain oil, and therefore should be disposed of safely. . Do not place either temporary or permanent loads on or against the unit. Mechanical . The dryer shall be fully disconnected or isolated from the compressed air supply and any remaining pressure released safely. . The refrigeration circuit shall be fully emptied of gas safely BEFORE work is attempted on any associated components. Refrigerant gas may be toxic and/or harmful (burns -both hot and cold), therefore use the necessary protective equipment (such as goggles and gloves) at all times when emptying the system, . If any heat or flame is to be used on or near the unit care shall be taken to avoid contact with combustible surfaces. Furthermore, it should be noted that the insulation materials and refrigerant might give off toxic fumes when heated. Whenever heat or flame is used the working area shall be thoroughly ventilated BEFORE and DURING this operation. Proper fire precautions shall be observed and the necessary fire safety equipment on hand, typical for electrical, oil and foam fires, . The refrigerant used is refrigerant R134a or R407C. No other type of refrigerant or mixture shall be used. . If recharging or adding refrigerant to the unit ensure correct refrigerant and oil are used, check labels on compressor identifying refrigerant being used. . Ester oils used in systems with R134a & R407C are very hygroscopic (adsorb moisture very quickly), therefore care should be taken to ensure that the systems and any ester oil containers are not left open to atmosphere for any length of time. . If any oil is removed from the system it shall be disposed of safely. Do not re-use or use for any other purpose. . When working on the dryers beware of any rotating components and any hot refrigerant pipework. . Observe any safety labels fitted to various parts of the dryer. Electrical . The dryers are designed to operate only on a 220/240 volt, 1 phase, 50-60 Hz live neutral and earth supply. THE EARTH CONNECTION MUST NEVER BE OMITTED. The voltage tolerance for each model is shown on the respective wiring diagr...
