EN | Operating manual Start-upWVM 40 -1450 31Vessel pressure gaugeOn both vessels, pressure gauges are fitted which show the operating overpressure. Theoperating overpressure indicates the operating phase of the relevant vessel:◊ During adsorption the pressure gauge should indicate the nominal operating overpressure.◊ During regeneration the indication of the pressure gauge on the regenerating vessel— must drop from the operating gauge pressure to < 0.5 bar gauge pressure during theexpansion phase,— must indicate a vacuum of 50 – 100 mbar during the drying phase.◊ During the pressure build-up phase the indication on the pressure gauge should again riseto operating overpressure level (both vessel gauges indicate the same operating pressure).Commissioning of the dryerRisk of injury from escaping hot regeneration gas!Hot humid air might escape from the the regeneration gas outlet at the vacuumpump. Therefore, keep clear of the blow-off outlet during operation of the unit.Risk of injury from crushing!During the switching from adsorption to regeneration, there is a risk of injuryfrom crushing at the universal shaft and the drives. During switching, stay clearof these components!Risk of injury from hot surfaces!During operation, certain surfaces of the dryer are heated to temperatures ofover 120 °C. At insulated dryers, screw connections might protrude from theinsulation. Do not touch hot surfaces. Allow surfaces to cool before you carryout any work at the dryer.Risk of injury from suddenly escaping gas!While the unit is under pressure, never remove any components or otherwiseinterfere with the dryer! Suddenly escaping gases can lead to serious injury!Prior to any work, release all pressure from the unit.◊ Operate the dryer only within the permitted limits. Operation of the dryer under conditionsfor which it is not designed may lead to malfunctions.◊ On no account should the factory settings of the control programme and the frequencyconverter be altered without consulting the manufacturer.◊ The higher the capacity of the dryer, the more noise it produces during operation. The oper-ator must therefore provide suitable protective equipment (e.g. earmuffs).◊ Depending on the size of the dryer, the compressed air network and the respective legalrequirements in your country, it may be necessary to perform initialisation according to thedirective for pressure equipment.◊ Check the dryer for visible damage and faults at regular intervals. Immediately reportchanges, also those regarding operational behaviour, to the institution or person in charge.In the event of an emergency or if safety-relevant malfunctions are observed, immediatelyswitch off the dryer. The dryer may only be restarted after the malfunction has been eliminat-ed.
