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 signicantly 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 specied 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.
