    INTRODUCTION Amiad filtration equipment has been designed to give long, trouble-free service when properly installed, operated and maintained. This manual contains important installation procedures and should be read prior to installing. This manual is also a guide for proper filter operation, maintenance and winterizing. It is important that maintenance personnel review this manual carefully, including the Safety Precautions and Warnings before performing any maintenance on this filter.

  • Page 5: Description And Filter Operation

    DESCRIPTION OF FILTER OPERATION Filtering process: The EBS series HVAC filter system is a sophisticated yet easy-to-operate automatic filter, with a self-cleaning mechanism driven by an electric motor. The filter system is also equipped with pump, control panel, isolation valves, and check valve all installed on a skid. The EBS filter system is designed to work with various types of screens in filtration degrees from 10 to 500 micron (HVAC STD is 50 micron).

  • Page 6: Installation

    Stages of cleaning cycle: Under normal operating condition the electrical control panel operates the "EBS" filter in the following manner; 1. The exhaust valve opens to atmosphere. 2. Five seconds delay. 3. The motor starts rotating the suction scanner shaft upward until it reaches the upper limit switch. 4.

  • Page 7: Commissioning, Start-Up And First Operation

    Electric wiring All electrical works at the installation site must be done by a qualified and authorized electrician only. Make sure that this electrician is fully aware of all the relevant safety instructions. Install the control board in a dry and protected place (In out-door installation sites make sure to use a special control board for out-door installation).

  • Page 8: Maintenance

    MAINTENANCE Before beginning any maintenance procedure, carefully read the safety instructions chapter of this document and make sure that all the workers at the filtration site are fully aware of and comply with, these and any other local safety instructions. General inspection of the filter operation This is the visual basic general inspection procedure of the filter for proper operation.
  • Page 9 Maintenance prior to long term cessation of filter operation The following must be done if the filter will not be operated for more than a month. Operate flushing cycle (If possible, with a closed downstream valve). Disconnect the control board from the power and lock the main switch before the limit switch disc reaches the switch.

    Please note that the screen is heavy and in order to avoid damage and injury it should be lifted only with Amiad’s standard Extractor and a standard lifting device operated by an authorized operator.
  • Page 12 Fold the Extractor upwards (Figure 1). Figure 1 Insert the Extractor into the screen, about a quarter from top. Make sure that the extractor cushions do not touch the stitch found along the screen interior. Pull the extractor up so that it is firmly set against the inside wall of the Screen (Figure 2) Figure 2: Attach a lifting device to the ring on the Extractor, and extract.
  • Page 13 REASSEMBLING THE EBS FILTER Before reassembling, visually check that all components are complete and in good mechanical condition. Before reassembling, carefully read the safety instructions in chapter 2 of this document and make sure that all the workers at the filtration site are fully aware of and comply with, these and any other local safety instructions. Install the seals (6) on the screen (7) and insert the screen into the filter housing (1).

  • Page 29: Safety

    The operating and maintenance instructions should be kept at the installation site of the Amiad Controller at all times. Applicable local regulations on the prevention of accidents and on the protection of the environment should be posted at the facility.

  • Page 30: Safety Devices

    It is available in a wide array of power classes and voltages to meet the needs of the market. The initiation of the Amiad filters’ self cleaning systems is by a signal from a differential pressure switch measuring the pressure of the filter inlet and outlet, a timer, control panel pushbutton for manual start or a remote start input.

  • Page 31: Transformer

    It is used to simplify the operation, thereby making the overall controller more robust. It has a special program designed by Amiad for this filter system. Although the software is available for download by the manufacturer, the program should not be altered without the consent of Amiad to avoid equipment malfunctions.

  • Page 32: Transportation

    • With the electrical source isolated, connect the appropriate electrical connections to the Amiad Controller. Check on the data plate to ensure the appropriate power supply is connected. • Add necessary short circuit protection as required on schematic.

  • Page 33: Deactivation

    • Check for leaks within the filter pipes and valves and tighten if necessary as described in the filter O&M. 4.2 Deactivation • Turn disconnect switch to the off position. • Turn all circuit breakers to the off position. • Apply appropriate lock-out/tag-out measures to ensure that power is not accidentally switched on.
