TYPICAL INSTALLATIONS

Z1185 LINT INTERCEPTORLint interceptors are designed primarily for laundry equipment.Connected in the discharge line from any washing machine,they intercept debris from soiled water. Interceptors contain apermanently affixed Acid Resistant Coated steel straining baffleto remove large items, buttons, stones, etc., and a removablestainless steel secondary screen to remove lint.

Note: The Z1185 Lint Interceptor can be sized based upon thenumber of washing machines which it serves.

Z1185 LINT INTERCEPTOR – OPERATION and MAINTENANCE INSTRUCTIONS

SIZINGThe sizing of this interceptor is generally based on the number ofwashing machines it will service. All units are made with a standardpipe size inlet and outlet and are capable of handling drainage volumesstandard to their respective pipe size.

DESIGNThe Zurn Z1185 Lint Interceptor is designed to separate solids suchas buttons, stones, string, and lint. This is accomplished through theprincipal of gravity separation. The bigger and heavier buttons, stones,etc., will be retained in the first compartment, while smaller andlighter particles, such as string and lint, will be trapped in the secondcompartment and on the removable screen.

OPERATIONThe wastewater flows from the inlet piping into the interceptor’s mainchamber passing through the affixed perforated primary screen andremovable secondary screen, into the main body chamber, then exitsthe interceptor to the sanitary drain system.

MAINTENANCECleaning should be done on a regular basis, either before or after thescreens become clogged. Remove the cover and clean out any largedebris from the first chamber and accumulation of lint in the secondchamber. Remove secondary screen assembly and clean off any lintbuild up. Reinstall the secondary screen into the interceptor. Makecertain the cover gasket is intact and clean. Apply a light coating ofoil on the cover gasket, which helps prevent the cover gasket fromadhering to the cover and aids in maintaining a complete seal. Thecover should then be placed back on the unit and secured. Efficiencyof operation is directly related to the level of maintenance.

MATERIALS and FINISHES

Zurn Cast Iron conforms to ASTM Specification for Gray Iron CastingsA 48-83, Class 25. It is produced utilizing the latest equipment andnewest developed foundry techniques. Zurn cast iron castings arecharacterized by a high degree of strength, corrosion-resistance,workmanship, and finish.

Zurn Duresist is a ductile iron complying with ASTM Specification A 536-84, Grade 60-45-10. Its physical properties make it ideal forgrates and drain components that are subjected to severe and heavyduty service. Its chemical characteristics make possible a degree ofcorrosion-resistance far superior to that of cast iron. Zurn Duresistexhibits remarkable stress qualities, possessing a yield strength inthe same range as that of cast carbon steel, while its ability to absorbthe shock loading of traffic areas is unequalled, making its use idealfor all areas where extra heavy duty service is a requirement – whetherindoors or outdoors – in chemical and metal processing plants orother industrial applications.

“Zurn Dura Coat” is a specially formulated paint designed to resistcracking and chipping. Dura Coat is a latex based coating developedto be used with cast iron substrate.

Zurn Galvanized Cast Iron is a process of applying heavy zinc coatingto a thoroughly cleaned iron casting. This coating contains 95% zinc.Zurn galvanizing can be supplied on all cast iron parts. It increaseslongevity and is recommended wherever the discoloration caused by oxidation of cast iron is objectionable. Galvanize should be usedin coastal and industrial areas where corrosive atmosphere may be encountered. Zurn galvanizing meets and exceeds FederalSpecification MIL-P-21035, MIL-P-26915A, MIL-P-26433, and MIL-C-10578 (Type II). It also meets ASTM A239-89 and is listed by Underwriters Laboratories, Inc. (U.L.)

Cadmium Plated Cast Iron is a process of applying a heavy cadmiumcoating to a thoroughly cleaned iron casting. This coating contains95% cadmium in a cold applied process. Cadmium plating can besupplied on all cast iron parts. It increases longevity and is recom-mended wherever the discoloration caused by oxidation of cast ironis objectionable.

Zurn Bronze is a semi-red brass conforming to ASTM Specificationfor Copper Alloy Sand Casting B 584-90, Copper Alloy No. 844. Theexposed surface is normally supplied possessing a satin sheen texturewhich allows it to blend unobtrusively with surrounding finishes. Whenthe application requires, Zurn Bronze can be polished to a high gloss.

Zurn Nickel Bronze is a unique material that is ideally suited totraffic-bearing grates and strainers in finished floor areas. It affordsthe combined advantage of greater strength, better appearance, andlonger service life at the same price as chrome plated brass. Superiorductility and shock resistance are the result of a copper nickel alloy(Copper Alloy 997) having a wearing surface similar in appearanceto satin chrome plate; however, because it does not have a platedsurface it cannot chip, peel, crack, or wear off. It is highly resistantto corrosion; however, the process of oxidation will naturally occurover time with most metals. Methods have been developed to prevent,preserve, and restore metals affected by oxidation.

Chrome Plated Bronze is ideal for installation in walls, gutters,and other areas where a bright decorative finish is desired, and isnot subject to the abrasive action of foot and other traffic. It is notrecommended for installations where the abrasion will eventuallywear through and cause peeling. It should always be specified forswimming pool fittings due to its high resistance to the halogens(chlorine, etc.), encountered in swimming pool sanitation.

Aluminum supplied is casting grade 319. This is an alloy containingboth silicon and copper. It is a solid cast metal in a pleasing lightgray color. The light weight, coupled with its exceptional strengthand corrosion resistance, makes it ideal for drain components suchas sediment buckets and strainers. When used with acid-resistingporcelain enamel coated drains, the possibility of chipping is minimized.

Zurn Stainless Steel castings are normally produced in Type CF8 (304)which is an 18-8 Austenitic Stainless possessing excellent corrosionresistant qualities. For some applications where conditions demand,Type CF8M (316) stainless steel can be supplied. Items formed fromstainless steel sheet and other stainless steel products are regularlyfurnished in Type 304 with 316 as an optional material.

A.R.C. Acid Resisting Epoxy Coating is a baked-on powder coating,which produces a smooth, hard, high gloss finish. This epoxy basedcoating offers high impact resistance and excellent life expectancyin all drainage applications. Zurn A.R.C. coating conforms to therequirements of F.D.A. (Food and Drug Administration) Regulation21-CFR5 117.1360.

A.R.E. Acid Resisting Porcelain Enamel is a substantially vitreous or glassy inorganic coating bonded to metal by fusion at a hightemperature above 800°F. This coating offers excellent acid, abrasion,and wear resistance. The coating is extremely hard and is the ultimatefor sanitation in drainage applications. Zurn A.R.E. coating conforms tothe requirements of F.D.A. (Food and Drug Administration) Regulation21-CFR5 117.1360.
