Mini retractor system TANKO-RF
WARNING
Risk of crushing during maintenance, cleaning and repair work! The container and the interfaces of the device (e.g. media connections) may be pressurized. There is a risk of death or severe physical injury. • Before starting work, depressurize the container and all lines. • Switch off all moving parts in the container and secure them to prevent them from being inadvertently switched back on or set in motion. • Only remove the device if it has been depressurized. • Wear protective gloves.
7.2 Switch-off Procedure In accordance with the type of device activation and how it is integrated (e.g. manual or automatic) on the cleaning plant, the switch-off procedure must be integrated and the following instructions must be observed when switching off. WARNING Risk from sudden, unforeseeable or unauthorized reactivation of the device (e.g. triggering of a start command as a result of incorrect operation of a start-up control device)! There is a risk of death or severe physical injury. Before performing any disassembly, maintenance, repair or cleaning work on the device, it is essential to carry out the following work steps in the specified order: Switch-off Procedure 1. Interrupt the supply of cleaning medium (e.g. slowly close the shut-off valve or ball cock). • Check that the supply of cleaning medium is stopped and there is no media pressure at the device. 2. Safeguard the supply of cleaning medium to prevent sudden, unforeseeable or unauthorized reactivation (e.g. lockable switch/shut-off elements). • Check that any supply of media is reliably prevented and insert dummy disks if necessary. Observe a cooling-down phase for media temperatures above 80 °C. • Make sure that the cleaning device and supply line for cleaning medium have been completely drained. 3. Disconnect the power supply to the higher-level plant/the device. • Check that the power supply is disconnected • Safeguard the power supply to prevent sudden, unforeseen or unauthorized reactivation (e.g. lockable switches) 4. Depressurize the container against the ambient pressure. • Safeguard the supply of steam or other media that affect the pressure to prevent sudden, unforeseen or unauthorized reactivation (e.g. lockable switches/ shut-off elements). • Make sure that the pressure inside the container matches the ambient pressure.
