(1) Pump down into a receiver or empty cylinder using Reclaim Equipment. (2) Use refrigerants to clean coils etc. (2) Clean coils etc. using a hand brush, vacuum or compressed air. (3) Leak test using pure refrigerant. (3) Leak test using Nitrogen and just a trace of refrigerant gas. (4) Recharge before mending leaks. (4) Find and mend leaks before recharging system. (5) Dispose refrigerant gas to waste. (5) Send used refrigerant gas back for reprocessing. Note: Disposal of refrigerants must be closely controlled. To dispose of refrigerant or a refrigerant system an approved agent must be used. If you have any doubt contact Denco Limited. Log Book In order to comply with BS EN 378, the user should keep an updated log book of the Compressed Air Dryer. The log book should record: (a) The details of all maintenance and repair work. (b) The quantities of new, re-used, or recycled refrigerant which have been charged on each occasion, and the quantities of refrigerant which have been transferred. (c) Any analysis of re-used refrigerant. (d) The source of re-used refrigerant. (e) Changes and replacements of components of the system. (f) The results of all periodic routine tests. (g) Significant periods of non-use. The log book should be kept in the machinery room or stored in a computer system. It must be accessible to the competent person when servicing or testing. Routine Maintenance It is not normally necessary to open the refrigerant circuit. If a problem is suspected it is strongly recommended that unit maintenance or repair is undertaken by a CITY & GUILDS 2078 (or equivalent) COMPETENT REFRIGERATION ENGINEER. A City and Guilds 2078 (or equivalent) certificate will soon be mandatory. Daily . Check that the "ON / OFF" switch/isolator is in the "ON" or " I " position. . Check condenser fan for airflow. Weekly . Check condensate drain operation. Monthly . Check condenser fins and grilles for cleanliness or damage. Repair as necessary. . Check condenser fan blades for damage. Quarterly . Check tightness of electrical connections. . Check all wiring for damage to insulation. . Check running current. . Clean condensate line strainer. Bi-annually . Check operation of refrigerant circuit (including temperatures and pressures) . Check the pipework connections for Annually . Thoroughly clean unit including condenser fins. . Check internal pipework and components for signs of wear or damage. Note: . Some safety cut outs are auto reset, and unless isolated from the mains the unit can be re-started without warning. . Pressure switches should be adjusted with the power off. . Any work done to the Compressed Air Dryer involving entry into the control panel, fitting gauges, adjusting controls, charging the system, evacuating the system or opening the system in any way, must be carried out by a FULLY QUALIFIED REFRIGERATION ENGINEER. Fault Finding The following fault finding chart relates various symptoms and faults of the refrigeration system. Before attempting to identify a refrigeration system fault it must first be established that the DESIGN CONDITIONS to the compressed air system are being met i.e. flow, pressure and temperature. Excessive overload will be caused by: 1. Excessive compressed air inlet temperature. 2. Compressed air pressure too low. 3. Compressed air flow in excess of design. 4. High ambient air temperature. Dirt, scale and/or excessive oil in the compressed air may cause one or more of the following: . Drain blockage leading to moisture being carried over into the compressed air system. . Excessive pressure drop in compressed air circuit. . Excessive fouling of the heat exchanger internal surfaces. PROBLEM CAUSE SYMPTOM REMEDY A Dew point too high Compressed air temperature too high. The digital display panel indicates a value > 4C° permanently Return the air inlet temperature to within the limits. Compressed air f...
