HMF2 Series Filter System Operating & Maintenance Manual Process Efficiency Products (PEP) filtration equipment has been designed to give long, trouble-free service when properly installed, operated and maintained. This manual includes installation and start-up procedures, and instructions for shutting down the HMF2 filter. Note: Recommendations for service frequency are minimums. For severe applications, more frequent service intervals are required.

HMF2 Series Filter System Operating & Maintenance Manual GENERAL DESCRIPTION PEP HMF2 Series Industrial Water Filters are permanent media type units specifically designed to remove suspended particulates from industrial and process water. HMF2 filters are suitable for both side-stream and in-line applications on pressurized systems. The standard pressure rating for HMF2 filter systems is 100 psig (700kPa). Optional higher pressure ratings and ASME coded vessels are available.
HMF2 Series Filter System Operating & Maintenance Manual 3. After the unit has been installed, the pressure gauge and air relief valves should be installed on the top of the filter vessel (some units will have vents already installed). The filter media (sand, gravel, etc.) should be loaded into the filter at this time. Refer to the “Loading Media” section in this manual for a description on how to load the media into the filter tank and the quantity of media necessary for each filter size.
HMF2 Series Filter System Operating & Maintenance Manual Note: The ¾” (20 mm) drain plug on HMF2 units is located on the tank bottom. Actuator Requirements PEP HMF2 filters utilize electric actuators to control the valve action between the filtration and backwash cycles. The electric actuator is designed for 110 VAC control. Air operated actuators are available as an option.
HMF2 Series Filter System Operating & Maintenance Manual current for standard models is listed in Table 5. 2. Install a service disconnect switch in plain sight of the filter and not more than 50ft (15m) away. 3. Install an externally operated manual or magnetic starter with thermal overload and fuse protection. If the unit is to be controlled remotely with a time clock, switch, or other device, a magnetic starter must be used.
HMF2 Series Filter System Operating & Maintenance Manual Operation And Maintenance Initial And Seasonal Start-Up Before initial start-up or after a shut down period, the HMF2 filter should be thoroughly inspected and cleaned. Caution: Perform the first five of the following recommendations with power off. Refer to the Safety Precautions on Page 8, regarding the safeguarding of maintenance personnel from biological contaminants, prior to initial and seasonal start-up. 1.
HMF2 Series Filter System Operating & Maintenance Manual do so could result in poor performance and/or personal injury. 11. Backwash the filter. After back washing the filter, check and record the inlet and outlet pressure gauge readings. The media should be back washed whenever the pressure drop across the filter (the difference between the two gauges) reaches approximately 10 psig over starting pressure. After First Hour Of Operation 1. Open the air relief valve on top of the filter tank.
HMF2 Series Filter System Operating & Maintenance Manual Seasonal Shutdown The following services should be performed if the unit is shut down for a prolonged time period. 1. Shut off all electrical power. 2. Close the shut-off valves in the filter inlet and outlet water lines. For units using a backwash source other than the system, close the shut-off valve in the line from that source. 3. Drain all external piping to and from the filter. 4.
HMF2 Series Filter System Operating & Maintenance Manual For manual control units using a backwash water source other than the system: 1. Shut off the electrical power to the pump motor. 2. Move the handle on the linkage to position the valves in backwash mode. 3. Allow the filter to backwash for approximately two minutes. 4. Move the handle on the linkage to position the valves in the filtration mode. 5. Re-start the pump motor. For manual control units using the system water for backwash: 1.
HMF2 Series Filter System Operating & Maintenance Manual Water Treatment Filtration is an effective way of reducing suspended particulates in fluids but is only one component of a water treatment program. Dissolved solids originally present in water remaining after evaporation cannot be eliminated by filtration. The concentration of these dissolved solids increases rapidly and can cause scale and corrosion.
HMF2 Series Filter System Operating & Maintenance Manual Safety Precautions All electrical, mechanical and rotating machinery constitute a potential hazard, particularly for those not familiar with its design, construction, and operation. Accordingly, adequate safeguards should be taken whenever working with or near HMF2 filter systems. Equipment operation, maintenance and repair should be undertaken by qualified personnel only.
