Introduction

3M™ High Flow Sanitary Design filter housing meets general-purpose industrial and food & beverage filtration needs, it is designed to accept a 10 inch 3M™ High Flow series filter cartridge. All wetted surfaces are constructed of 316L stainless steel. The housing closure V-band clamp is of 300 series stainless steel. A single V-band clamp housing closure and independently sealed cartridge within the housing provide quick and easy cartridge change-outs.

CAUTION

To reduce the risk associated with property damage:

• Do not exceed maximum operating pressure or temperature limits.

IMPORTANT NOTE

• Filter housings are normally shipped without a cartridge. Before putting filter housing in service, be certain that the proper filter cartridge is installed. 3M High Flow series filter cartridge installation/operating instructions are packaged with each box of filter cartridges.

Operating Instructions

Operating Data

I. Housing Installation

• 1. Unpack and inspect the housing for any shipping damage.
• 2. Remove the protective covers from inlet and outlet nozzles.

• WARNING

  To reduce the risk associated with crush related injuries:
  • Do not attempt to open the housing cover unless housing is bolted and anchored in place.
• 3. Ground the housing in accordance with local code requirements.
• 4. Using the appropriate fittings and fasteners (not provided), connect the inlet/outlet nozzles to the system piping. Installation of valves (recommended) into the system piping upstream and downstream in close proximity to the housing will allow for easier maintenance when replacing the filter cartridges. Additionally, installation of pressure gauges will facilitate identifying pressure drop, thereby indicating when filter element replacement is required. Refer to Figure 2.

II. Installing Vent Valves

The filter housings are supplied with a vent port and gauge port on the cover. Installation of a 1/2" sanitary vent valve (recommended) into the vent port will allow for easier evacuation of air from the housing during preparation for operation. The inlet pressure gauge can be installed on the gauge port on top of the cover. Refer to Figure 2.

III. 3M™ High Flow Filter Cartridge Installation/Replacement

CAUTION

To reduce the risk of exposure to contaminants:

• Always use appropriate personal protective equipment (PPE) when installing, operating or changing the product as per your standard operating procedure.
• Dispose of used cartridges in accordance with federal, state, and local laws and regulations.

Cartridge Installation

• 1. Remove cartridge from packaging and ensure that the cartridge O-ring is properly seated in the O-ring groove of the bottom end-cap. This O-ring is not reusable. Verify filter housing and filter cartridge compatibility with the chemistry and temperature of the process fluids. O-rings are available in a variety of materials designed to be compatible with most manufacturing processes.
• 2. Lubricate cartridge O-ring with water or process fluid to ease installation.
• 3. With the cartridge handle approximately perpendicular to the direction of the flow, insert the cartridge into the filter housing and onto the cartridge receptacle on the diaphragm. Push the cartridge into the filter housing until it is fully seated. To ensure proper cartridge seating, gently twist the cartridge handle back and forth while pushing the cartridge into the housing. Do not force, jam or drop the cartridge in place.
• 4. Slowly turn the cartridge clockwise (refer to Figure 3) holding the handle firmly until it stops (after 90° rotation). At this point, the O-ring is fully engaged into the cartridge receptacle. Maximum allowable turning torque: 100 inch-pound. To ensure that the cartridge is locked into the cartridge receptacle, gently pull the cartridge as if removing it but without rotating the filter cartridge handle. If the cartridge releases, repeat steps 3 and 4.
• 5. Lubricate cover gasket with water or process fluid to ease installation. Assemble gasket and housing cover; center cover flange with housing flange. Position the cover clamp and tighten by hand until T-bolt gap is closed within 1/2" (refer to Figure 4). Ensure the T-bolt is engaged vertically in the clamp channel. Do not overtighten.

IV. Starting

With the vent valve open, open the inlet valve and slowly fill the filter housing. When a continuous stream of liquid comes out of the vent hole, close the inlet valve and close the vent valve. Open the inlet valve and check for leakage. If leakage is detected, shut the inlet valve, open the vent valve to relieve pressure, and re-tighten the V-Band clamp. Repeat leakage check. Open the inlet and outlet valves. Filter housing is now in operation.

V. Cartridge Life

3M™ High Flow series filter cartridges have been designed to filter a wide range of industrial fluids. The period at which cartridges should be replaced can only be determined by actual experience in your system. However, it is generally recommended that the cartridges be replaced when differential pressure across the cartridges reaches 25-35 psi, or at least once per year whichever condition occurs first. Do not exceed 35 psid.

IMPORTANT NOTE

• Do not exceed recommended maximum pressure drop across the filter cartridge as doing so may result in physical damage to the filter cartridge.

Cartridge Replacement

• 1. Shut off inlet and outlet valves. Open vent valve to relieve pressure. Drain the vessel out the outlet port.
• 2. When the filter housing is drained, loosen cover clamp nut and unsnap T-bolt.
• 3. Turn the filter cartridge handle 90° (refer to Figure 5) counter-clockwise until it releases out of the cartridge receptacle. Pull the cartridge handle upward to remove the cartridge from the filter housing. Clean all parts thoroughly and inspect cover gasket and replace if damaged.
• 4. Inspect the following items for damage and replace if necessary:
  • T-bolt threads (look for deformed/sheared threads).
  • Cover flange seal surface (look for scratches/deformation).
  • Housing flange seal surface (look for scratches/deformation).
  • Clamp (inside surfaces, look for cracks, deformation).
