SIZING
All Zurn solids interceptors are designed for gravity flow where
minimal head is expected. Zurn solids interceptors are designed
to accommodate the flow rate of their inlet and outlet pipe size,
provided they are maintained and kept clean.
Zurn solids interceptors should be sized by both expected flow rate
and holding capacity. Sizing for the Z1181 solids interceptor should
be sized by the number and size of the sinks being served as is the
case with the Z1170 grease interceptor.

Z1180 SOLIDS INTERCEPTOR – OPERATION and MAINTENANCE INSTRUCTIONS
SIZING
There are no sizing requirements for this interceptor except to specify
the inlet and outlet size. All units are made with a standard 2" [51 mm]
pipe size inlet and outlet, reduced to 1-1/2" [38 mm] with a bushing
when specified, and are capable of handling drainage volumes standard
to their respective pipe size.
DESIGN
The Zurn Z1180 Solids Interceptor is designed to recover all types of
solids from precious metal particles to plaster, clay, or similar materials.
This is accomplished through the principal of gravity separation.
Particles of various sizes and weights are trapped in the bucket.
OPERATION
The wastewater flows from the inlet piping into the removable bucket,
passing through the screen, into the main body chamber, then exits
the interceptor to the sanitary drain system.
MAINTENANCE
Cleaning should be done on a regular basis, either before or after the
bucket becomes clogged. First unlatch and remove the cover/bucket
assembly, twist and lift the bucket to remove from cover, take out the
screen and clean out all debris. Replace the screen in the bucket,
next place the bucket back on the cover, twist to reattach. Make
certain cover gasket is intact and clean. Apply a light coating of oil on
the cover gasket, which helps prevent the cover gasket from adhering
to the cover and aids in maintaining a complete seal. The cover/
bucket assembly should then be placed back in the unit, making sure
the screen in the bucket is on the outlet side as shown, and relatch
to secure cover. Efficiency of operation is directly related to the level
of maintenance.

Z1183-DF SOLIDS INTERCEPTOR with DISPOSABLE FILTER BAGS – OPERATION and MAINTENANCE INSTRUCTIONS
SIZING
The sizing of this interceptor relates to the size of the Z1170 grease
interceptor it is being used with. All units are made with a standard
no-hub pipe size inlet and outlet, and are capable of handling drainage
volumes standard to their respective pipe size.
DESIGN
The Zurn Z1183-DF Solids Interceptor is designed to recover food
waste from sinks, garbage grinders, and dishwashers. This is
accomplished through filtration. The food wastes are retained in the
disposable filter bags while allowing wastewater to pass through to
the outlet drainage line.
OPERATION
The wastewater flows from the inlet piping into the main body chamber.
It is then redirected through the solids filter bags by the retainer plate.
Solid material is captured in the filter bag allowing the wastewater to
pass through. Any solids that pass through the filter bag will settle into
the removable sediment basket. The filtered wastewater then exits the
interceptor to the sanitary drain system.
MAINTENANCE
Cleaning should be done on a regular basis, before the sediment
basket or filter bags become clogged. Remove the cover, lift out the
filter bags from the retainer plate and properly dispose of them.
Remove the retainer plate and sediment basket and clean out all
debris, hosing off the interior as necessary. Replace the basket and
retainer plate into the interceptor. Insert clean filter bags into the
retainer plate. Make certain cover gasket is intact and clean. Apply a
light coating of oil on the cover gasket, which helps prevent the cover
gasket from adhering to the body and aids in maintaining a complete
seal. The cover should then be placed back on the unit and secured.
Efficiency of operation is directly related to the level of maintenance.

Zurn Cast Iron conforms to ASTM Specification for Gray Iron Castings
A 48-83, Class 25. It is produced utilizing the latest equipment and
newest developed foundry techniques. Zurn cast iron castings are
characterized 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 for
grates and drain components that are subjected to severe and heavy
duty service. Its chemical characteristics make possible a degree of
corrosion-resistance far superior to that of cast iron. Zurn Duresist
exhibits remarkable stress qualities, possessing a yield strength in
the same range as that of cast carbon steel, while its ability to absorb
the shock loading of traffic areas is unequalled, making its use ideal
for all areas where extra heavy duty service is a requirement – whether
indoors or outdoors – in chemical and metal processing plants or
other industrial applications.
“Zurn Dura Coat” is a specially formulated paint designed to resist
cracking and chipping. Dura Coat is a latex based coating developed
to be used with cast iron substrate.
Zurn Galvanized Cast Iron is a process of applying heavy zinc coating
to a thoroughly cleaned iron casting. This coating contains 95% zinc.
Zurn galvanizing can be supplied on all cast iron parts. It increases
longevity and is recommended wherever the discoloration caused
by oxidation of cast iron is objectionable. Galvanize should be used
in coastal and industrial areas where corrosive atmosphere may
be encountered. Zurn galvanizing meets and exceeds Federal
Specification 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 cadmium
coating to a thoroughly cleaned iron casting. This coating contains
95% cadmium in a cold applied process. Cadmium plating can be
supplied on all cast iron parts. It increases longevity and is recom-
mended wherever the discoloration caused by oxidation of cast iron
is objectionable.
Zurn Bronze is a semi-red brass conforming to ASTM Specification
for Copper Alloy Sand Casting B 584-90, Copper Alloy No. 844. The
exposed surface is normally supplied possessing a satin sheen texture
which allows it to blend unobtrusively with surrounding finishes. When
the application requires, Zurn Bronze can be polished to a high gloss.
Zurn Nickel Bronze is a unique material that is ideally suited to
traffic-bearing grates and strainers in finished floor areas. It affords
the combined advantage of greater strength, better appearance, and
longer service life at the same price as chrome plated brass. Superior
ductility and shock resistance are the result of a copper nickel alloy
(Copper Alloy 997) having a wearing surface similar in appearance
to satin chrome plate; however, because it does not have a plated
surface it cannot chip, peel, crack, or wear off. It is highly resistant
to corrosion; however, the process of oxidation will naturally occur
over 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 is
not subject to the abrasive action of foot and other traffic. It is not
recommended for installations where the abrasion will eventually
wear through and cause peeling. It should always be specified for
swimming 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 containing
both silicon and copper. It is a solid cast metal in a pleasing light
gray color. The light weight, coupled with its exceptional strength
and corrosion resistance, makes it ideal for drain components such
as sediment buckets and strainers. When used with acid-resisting
porcelain 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 corrosion
resistant qualities. For some applications where conditions demand,
Type CF8M (316) stainless steel can be supplied. Items formed from
stainless steel sheet and other stainless steel products are regularly
furnished 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 based
coating offers high impact resistance and excellent life expectancy
in all drainage applications. Zurn A.R.C. coating conforms to the
requirements of F.D.A. (Food and Drug Administration) Regulation
21-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 high
temperature above 800°F. This coating offers excellent acid, abrasion,
and wear resistance. The coating is extremely hard and is the ultimate
for sanitation in drainage applications. Zurn A.R.E. coating conforms to
the requirements of F.D.A. (Food and Drug Administration) Regulation
21-CFR5 117.1360.
