  • Page 3: Foreword

    Foreword Read the Manual Before WARNING Operation Do not use means other than those recommended by the manufacturer to accelerate the defrosting process or to clean. The appliance shall be stored in a room with no ignition sources (for example: open es, gas appliance, or electric heater).
  • Page 4 the components are constructed of materials that are inherently resistant to being corroded or are suitably protected against being so corroded. REPAIRS TO SEALED COMPONENTS DD.5.1 During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
  • Page 5 system. When the al OFN charge is used, the system shall be vented down to the atmospheric pressure to enable work to take place. This operation is vital if brazing operations on the pipework are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.
