  • Page 3: Introduction

    The filters may be used for both side-stream and full stream applications in pressurized and non-pressurized systems. Standard BMF series filter vessels are rated for 100 PSI for the 54” thru 96” tanks. All pressure ratings are based on a maximum temperature of 100 degrees Fahrenheit.
  • Page 4 Rigging Amiad BMF filters should be lifted with a forklift or overhead crane. If these units are lifted with an overhead crane, lifting straps must be located below the filter skid and should not come in contact with the filter components. If no skid is supplied, lift from the lifting lugs located on the filter vessel top.

  • Page 5: Start-Up & Operation

    Loading the Filter Media The special sand media used in Amiad BMF media filters is shipped in one half cubic foot bags and each bag weights 50 lbs. Refer to Table 5 for media loading quantities. Media quantity may vary with vessel pressure ratings.
  • Page 6 Cold Weather Operation Amiad BMF media filters that will be exposed to below freezing ambient temperatures require protection to prevent freezing. Installation in a heated indoor space is the best means of preventing water from freezing in a filter. When indoor installation is impractical because of filter location or space limitations, supplemental heat must be supplied through the use of electrical heater tape and insulation.

    Maintenance Procedures Refer to Table 1 for suggested operation and maintenance schedules of Amiad BMF systems. Pump Pre-strainer (if equipped) Warning! Disconnect all electrical power prior to performing pump maintenance. The filter pre-strainer basket on the pump inlet must be checked regularly and kept free of debris. Failure to do so may damage the pump and/or motor.

    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 29: 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.

    and checked before shipment. Raising the overloads current value over the factory settings or removing the overloads from the controls will inhibit the ability of the controller to properly protect the motor. This setting should not be modified without contacting the manufacturer first. Transformer The transformer steps the high voltage down to a usable low voltage for the control components.
