Page 4: General Safety Requirements
Delivery is an integral part of the manual. Other items of equipment, not supplied under the Scope of Delivery from Donaldson, should be installed, operated and maintained according to the documentation supplied with the respective equipment. Any modification carried out on the ‘as supplied’ equipment may reduce reliability and safety, and will nullify warranty;... - Page 5 Installation, Operation and Maintenance manual Series DCE HV500 Compressed air is recommended for collectors that operate using reverse jet cleaning. Alternative gases should be assessed before use to ensure that explosive atmospheres are not introduced during media cleaning. Where the equipment supplied is suitable for working within a potentially explosive atmosphere (as defined by Directive 2014/34/EU) it will be according to the categories and conditions marked on the collector serial nameplate.

Lifting collector to vertical position Once the DCE HV500 Series collector has been placed on the floor in a horizontal position it can then be two-point lifted, using the lifting points provided, into a vertical position (figure 2 and figure 3). - Page 9 Installation, Operation and Maintenance manual Series DCE HV500 FIGURE 3: Two-point lifting from horizontal to vertical position Lifting points (2) Longer legs FIGURE 4: Lifting from vertical position Whilst slung in a vertical position the legs provided should be bolted into position on the vessel (the longer legs are attached to the clean air chamber) and then the bracings fitted to the front and rear legs (figure 4).

Page 10: Compressed Air Requirements
Series DCE HV500 Compressed air requirements DCE HV500 Series dust collectors require an independent supply of clean, dry, oil- free compressed air. Details of atmospheric pressure and quantity are given in Table 3 (refer to ‘Specification’ section). A design label is also attached to each manifold. -
Page 11: Exhauster Motor
Installation, Operation and Maintenance manual Series DCE HV500 Exhauster motor The exhauster motor used in conjunction with the DCE HV500 dust collector will need to be wired to a suitable control panel for the type of motor installed. This control panel should be designed in such a way to comply with local legislation for electrical installations. -

Page 13: Commissioning Check List
Installation, Operation and Maintenance manual Series DCE HV500 The plastic liner must be fitted in the dust container before operating the collector. Dust containers are of heavy duty construction, supplied on castors for ease of handling. Full plastic liners may be of considerable weight depending of the type of dust being collected and therefore consideration should be made to the safe working load for lifting. -
Page 14: Commissioning
It is a requirement of the Supply of Machinery (Safety) Regulations 1992 to provide adequate isolation and emergency stop facilities. Due to the varied nature of site installations this cannot be provided by Donaldson but instead is the responsibility of the customer. -
Page 15: Shut-Down Sequence
This procedure is not recommended where an explosion relief assembly is fitted, as damage could result to the bursting panel. In such cases consult with Donaldson. 2. After 10-15 minutes, switch off controller and compressor but leave discharge equipment running to ensure that it is emptied. -
Page 16: Operation
Installation, Operation and Maintenance manual Series DCE HV500 OPERATION Principle of operation Dust-laden air is ducted into the chamber containing the filter elements where it collects on their outer surfaces. A layer of dust builds up on the outside of the elements as the air itself penetrates the media (figure 6a). -
Page 17: Maintenance
Before any work is carried out, ensure the equipment is adequately isolated. Ensure the pneumatic system is fully isolated and depressurised before any work is carried out. For ancillary equipment not manufactured by Donaldson, refer to manufacturer’s instructions. If it is unavoidable to work on the equipment while a potentially explosive atmosphere is present, care should be taken to avoid introducing ignition sources not present during expected operation. - Page 18 Installation, Operation and Maintenance manual Series DCE HV500 Filter resistance can be checked by connecting a U-tube manometer or differential- type pressure gauge to tapping points on the collector body (figure 1). This will give a continuous indication of the state of the filter. Once running, the operating resistance will be relatively stable, the actual value depending on the air volume and the characteristics of the dust being handled.

Page 19: Servicing Schedule
Care should be taken to avoid injury. If it is found necessary to replace a diaphragm, use the following procedure (figure 8): Use service kit available from Donaldson. Switch off exhauster and compressed air supply. 2. Remove nylon tube (A) by pulling out from valve. - Page 20 Installation, Operation and Maintenance manual Series DCE HV500 Annually Moisture separator – Isolate the compressed air supply and release the manifold pressure via the moisture separator. Remove and clean the filter element. 2. Air manifold – Having isolated the compressed air supply and released the manifold pressure, remove the drain plug and air inlet connections and clean out any accumulated sludge and inspect to any current local legislation.
- Page 21 Installation, Operation and Maintenance manual Series DCE HV500 Any dust falling into the valve exhaust port should be removed before restarting the collector. 5. Jet Tubes – Check that the jet tubes are clean and that the jet orifices are clear. 6. Flameproof maintenance – It is important that all flameproof enclosures, motors and cable glands are inspected for corrosion and tightness.
- Page 22 *To run filter clear, switch off main blower/exhauster only and allow the controller to perform several complete cleaning cycles before switching off compressor etc. This procedure is not recommended where an explosion relief assembly is fitted, as damage could result to the bursting panel. In such cases consult with Donaldson.
