Safety Information
Do’s and Don’ts
• Do read and understand these instructions before installing or using the strainer.
• Do use Dixon spare parts when replacing any components of the strainer.
• Do Not attempt to service the strainer while under pressure.
• Do Not place the strainer in an application where the service ratings are exceeded.
• Do Not attempt to modify the strainer assembly as it may compromise the integrity of the assembly and will void all warranties.
Safety Precautions When Installing Strainer
• Do relieve product line pressure before attempting to install strainer assembly.
• Do check the distance between the clamp ferrules to assure there is proper clearance for the strainer assembly.
• Do Not install a damaged lter or strainer.
• Do Not install strainer between damaged clamp ferrules.
• Do Not install strainer between tubing that is signicantly out of alignment.
Safety Precautions When Strainer is in Operation
• Do monitor the strainer assembly for any signs of leaks.
• Do check all clamp assemblies often to ensure that they have not loosened from any excessive vibration.
• Do check the pressure on either side of the strainer to monitor for any possible blockages.
• Do Not attempt to loosen any clamp assemblies while the strainer is in operation.
• Do Not attempt to perform any type of service or adjustment to the strainer during operation.
Safety Precautions When Servicing the Strainer
• Do drain piping run as much as possible.
• Do vent line to relieve any pressure.
• Do secure necessary lifting equipment to strainer assembly if necessary.
• Do remove line clamps rst before removing strainer body clamp.
• Do use caution and wear protective clothing if strainer has been used in applications using acids or other chemicals that may be
harmful.

Care of Stainless Steel
The stainless steel components in Dixon Sanitary equipment are machined, welded and assembled by skilled craftsmen using
manufacturing methods that preserve the corrosion-resistant quality of the stainless steel.
Retention of corrosion-resistant qualities under processing conditions requires regular attention to the precautions listed below.
1. Regularly check all electrical devices connected to the equipment for stray currents caused by improper grounding, damaged
insulation or other defects. Corrosion: Pitting often occurs when stray currents come in contact with moist stainless steel.
2. Never leave rubber mats, ttings, wrenches, etc. in contact with stainless steel. Corrosion: Pitting or galvanic action. Objects
retard complete drying, preventing air from reforming the protective oxide lm. Galvanic corrosion occurs when two dissimilar
metals touch when wet.
3. Immediately rinse equipment after use with warm water until the rinse water is clear. Clean the equipment (manual or CIP)
as soon as possible after rinsing. Corrosion: discoloration, deposits, pitting. Product deposits often cause pitting beneath the
particles.
4. Use only recommended cleaning compounds. Purchase chemicals from reputable and responsible chemical manufacturers
familiar with stainless steel processing equipment, they continuously check the effects of their products on stainless steel.
5. Use cleaning chemicals exactly as specied by the manufacturer. Do not use excessive concentrations, temperatures or exposure
times. Corrosion: Pitting, discoloration, stress cracks. Permanent damage often occurs from excessive chemical concentrations,
temperatures or exposure times.
6. For manual cleaning, use only soft non-metallic brushes, sponges or pads. Brush with the grain on polished surfaces, avoid
scratching the surface. Corrosion: Pitting, scratches. Metal brushes or sponges will scratch the surface and promote corrosion
over a period of time. Metal particles allowed to remain on a stainless steel surface will cause pitting.
7. Use chemical bactericides exactly as prescribed by the chemical manufacturer in concurrence with local health authority. Use
the lowest permissible concentration, temperature and exposure time possible. Flush immediately after bacterial treatment. In no
case should the solution be in contact with stainless steel more then 20 minutes. Corrosion: Protective lm destroyed. Chlorine
and other halogen bactericides can destroy the protective lm. A few degrees increase in temperature greatly increases chemical
activity and accelerates corrosion.
8. Regularly inspect the joints in pipelines. Be sure all connections are tight tting without binding. Corrosion: Crevice corrosion.
Small crevices caused by improperly seated gaskets will promote crevice corrosion. Stainless steel under stress will develop
stress cracking especially in the presence of bactericides containing chlorine.
9. Regularly inspect equipment for surface corrosion (i.e. pitting deposits, stress cracks, etc.). If deposit or color corrosion is
detected, remove it immediately using mild scouring powder and detergents. Rinse thoroughly and allow to air dry. Review
production and cleaning procedures to determine the cause. Note: If corrosion is not removed, the protective lm cannot be
restored and corrosion will continue at an accelerated rate.

Installation & Start Up
Inline, Side Entry and Side Outlet
1. Be sure adequate line supports exist to prevent stress on ttings and strainer body.
2. Install supports approximately every ten feet on either side of the strainer assembly.
3. All Dixon strainer assemblies operate in any position. However, to maintain 3A certication, the unit must be installed in the
vertical position.
4. Ensure that the strainer assembly is in the proper orientation so that the inlet and outlet are congured according to the markings
on the strainer body.
5. Align the lter, strainer and gaskets such that they are centered with the clamp ferrule faces.
6. Clamp ends must be parallel in all planes and on center line. CAUTION: Failure to ensure line ends are centered and parallel in
all planes, could result in leaking from the valve or strainer assembly.
7. Tighten all standard clamp assemblies to 25 in-lbs and high pressure bolted clamps to 20 ft-lbs.
8. Once strainer assembly is installed, cycle water through the unit to ensure there are no leaks from any of the connection points.
Dual Strainers
1. When installing a dual strainer assembly with ball or buttery valves, install supports on both sides of the valves as close to the
connections as possible.
2. Before starting product ow through the dual strainer unit, ensure that the valves are in the correct position. On manual ball
valves, check the ow path machined in the valve stem to ensure that the valves are positioned so that product is only owing
through a single strainer at any one time. For actuated valves, check the indicator beacon located on top of the actuator.
3. For proper ow direction and orientation, please refer to the following diagram.

General Maintenance
1. WARNING: Prior to loosening the ferrule clamps, be sure to drain piping as much as possible to prevent injury.
2. Vent line to relieve any pressure that could potentially be built up in the strainer housing.
3. Loosen clamps to decompress valve gasket seals.
4. Secure any necessary lifting equipment required to remove the strainer from the line.
5. Completely remove clamps from the strainer ends and remove the unit from between the clamp ferrules.
6. Check all wetted components for any sign of damage that could have resulted from large particulate or water hammer.
7. For dual strainer units, inspect valves for any signs of damage and replace wetted components as necessary. Refer to Dixon ball
and buttery manuals for instructions.
8. Remove and replace as necessary the lter bag or mesh over screen.
9. The strainer back up tube should not need to be replaced unless signicant damage has occurred as a result of abnormally harsh
media.

Page 9
Changing Filter Media
1. When installing a lter sock or over screen, save the original packaging. This will aid in identifying your lter media type when
reordering.
2. Relieve all pressure inside the system and make certain the ltration system is drained of all liquid.
3. Refer to the disassembly section of the manual for procedures on removing the back-up tube and lter bag or over screen
assembly.
4. If you are using a lter bag (8), remove retaining rings (9) from either end of the strainer back-up tube (4). Check the retaining rings
for any sign of wear or damage, and replace as necessary.
5. If you are using an over screen (7), slide the over screen off of the strainer back-up tube (4) and clean or replace as necessary.
6. Insert a new lter bag (8) or over screen (7) over the strainer back-up tube (4). If using a lter bag, insert the retainer rings (9)
inside each end of the strainer back-up tube to hold the lter bag in place.
7. Refer to the Assembly section of the manual for reassembly of the strainer unit.
