pump for an extended period of time with the pump rotating backwards! If rotation is
backward, have a qualified electrician change pump motor leads to correct rotation.
6. Set pneumatic regulator to 85 PSI as indicated by the gauge on the regulator. Run a test on
the valve operation to ensure that enough air and pressure is available.
7. Differential pressure switch comes set from the factory at 16 PSI.
8. With the air relief valve open, check the isolation valves in the filter inlet and outlet water lines
to verify they are open. Make sure the pump is primed. Start the pump and allow the filter
vessel to fill. Close the manual air relief valve on top of the vessel after all air has been vented
from the vessel.
9. Check the voltage and current of all leads on the pump motor. The current draw should not
exceed the pump motor nameplate rating. Check for any unusual noise or vibrations.
10. Check the unit for any air or water leaks. Any air leaks in the pump suction piping must be
found and repaired. Failure to do so could result in poor performance and/or personal injury.
11. Backwash the filter 3-4 times initially to remove any fine grit or contaminants that may be in
the media. After backwashing the filter, check the pressure gauge on top of the filter tank and
record the clean media operating pressure (inlet gauge). The media should be backwashed
whenever the pressure drop across the filter media reaches 16 PSI, or every 24 hours,
whichever occurs first.
After First Hour of Operation
1. With the filter pump running, the auto air vent releases air from top of the filter vessel.
Excessive air release generally indicates a leak, which must be repaired. Air
accumulation in
the filter vessel can result in an unsafe condition due to the stored high energy potential of
any
compressed air within the vessel.
2. Again, check the unit for any unusual noise or vibration.
3. Again, check unit for any air or water leaks.
Operation
During operation, to ensure long term dependable operation, the filter should be inspected, cleaned
and lubricated on a regular basis. The required service functions and recommended frequency
(minimums) for each are shown in the Operating and Maintenance
Table 1 . If any problems occur,
please refer to Table 7 for Troubleshooting Procedures . If you have any questions, please contact the
factory.
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. The parts of the filter that must be heat traced and insulated are: pump, pump pre-
strainer, pump piping and valves,
differential pressure switch tubing and filter vessel. The unit should
be drained when it is to be shut down for any period of time. Refer to the following section, Seasonal
Shutdown , for recommendations.
Seasonal Shutdown
The following services should be performed when the unit is to be taken out of service for an extended
period of time.
1. Shut off all electrical power.
2. Close the isolation valves on the filter inlet and outlet water lines. For units using a backwash
source other than the system, close the isolation valve on the line from that source also.
3. Drain all external piping to and from the filter.
4. Loosen the bolts that hold the filter vessel access covers in place and remove the cover.
Lubricate the bolts if necessary. Replace the cover gaskets if necessary.
5. Inspect the over-drain assembly and media pack. If the media in contaminated, remove the
foreign material and replace the filter media if necessary. Replace the filter vessel access
covers and secure the bolts.
