OPERATIONAL INFORMATIONWe DO NOT use multiple choice menu driven voice mail in response to your important telephone call.WE ANSWER THE TELEPHONE with actual human beings experienced in taking your order for standard products or provid-ing technical application assistance.Our PERSON TO PERSON order desk is open 7:30 am to 4:00 PM (PST), Monday through Friday.Our voice mail is on at all other times. We WILL respond to your important message at the beginning of our next businessday.Our FAX machine is never turned off. (805) 988-6804 TECHNICAL APPLICATION ASSISTANCEIn depth technical information to help you select the optimum HARWIL product for your particular application is as close asyour telephone and fax machine. • PHONE: (805) 988-6800, FAX (805) 988-6804 • We can modify standard units for special applications. • We also design and manufacture completely new models for O.E.M. applications. EMERGENCY DELIVERIESOur 50 year history of supplying support items such as level controllers, fluid flow and liquid level switches to a broadspectrum of industries has “burned” into our collective brains the importance of fast delivery of emergency orders to keepour customers “on line.” To this end we: • Attempt to keep reasonable numbers of all standard models in stock, i.e. physically on our “emergency shelf” for instantaneous delivery of small orders. • We have shipped orders received by 9:00 AM local time that same day. ORIGIN OF PRODUCTS99% of the products listed in this catalog are conceived, designed, developed, manufactured and marketed by HARWILCorporation. The exception in the current catalog is The Intrinsically Safe Relay which is a product of Warrick Controls, Inc.(USA) BACKGROUNDHARWIL Corporation was formed in 1956. Electromechanical fluid flow and liquid level switches were one of our initialproduct lines and are now the major product line. Current development is directed toward electronic and electro-optical flowand level switches and controls. TRADEMARKSViton is a registered trademark of DuPont performance Elastomers. i 10-8-15

Intrinsically safe electrical equipment and wiring may be installed in any hazardous location ofany group classification for which it is accepted without requiring explosion-proof housings or other means or protection.OPERATIONAL FEATURES: • Modern, cost effective, solid state technology eliminates expensive, old style, explosion proof enclosures. • Installation and maintenance of equipment is fast, simple, and inexpensive. • Long-term safety and reliability is increased substantially by elimination of sealed joints, special housings, and gaskets. • Epoxy encapsulation of solid state circuitry provides protection against harsh industrial environments. • Immunity to normal shocks, vibrations, thermal expansion, and contraction.SINGLE UNIT PROVIDES TWO MODES OF OPERATION FOR LIQUIDLEVEL APPLICATIONS 1. Single Non-Latching Input for high or low level alarm. 2. Dual Latching Input for Pump Up/Pump Down liquid level control.APPROVED FOR USE IN THE FOLLOWING HAZARDOUS AREAS:CLASS 1 AND 2 DIVISION 1 GROUPS A, B, C, D, E, F, AND GCLASS 3Approved: Factory Mutual System and U.L.Versatile Single and Dual Input Switching Logic also allows one Unit to be Usedin a Multitude of Alarm and Control Applications, Such as: Fluid Flow Pressure Temperature Limits Speed Proximity Conductivity Position 40 10-8-15

EPOXY AND PTFE COATINGS OF FLUIDFLOW AND LIQUID LEVEL SWITCHESLONG-TERM PROTECTIVE COATINGSAll metal wetted materials of our fluid flow switches (Models Q-1, Q-4E, Q-5, Q-5SS, QD Series) and liquid level switches (Models L-5,L-5SS, LD series) are now available with baked on epoxy or PTFE (Polytetrafluoroethylene)* coatings.PTFE coatings are similar to the non-stick coatings commonly found on household cookware, from spoons to frying pans. These plasticcoated surfaces provide greater long-term protection against chemical corrosive attack of virgin metal substrate, such as brass, 316 Stain-less, or Hastelloy C.Plastic coated surfaces also provide protection on the other end of the scale, (e.g. leaching of alloy components from brass by ultra-purewater). The coating of low cost substrate metals to provide superior chemical resistance is thus a cost effective solution of special situa-tions where all plastic or exotic metal solutions are not available at any reasonable price, or time scale. These epoxy and PTFE coatingsprovide increased protection against:• Chloric Acid • Sea Water• Chromic Acid • Sewage• Contaminated Water • Skydrol• Ferric Chloride • Sulfuric Acid• Gasoline • Ultra-Pure Water• Hydrocarbons • Waste Waters• Hydraulic Acid• NaOH• Nitric AcidCOATINGS AVAILABLEEverlube 6108 thermal cured PTFE.Everslik 1201 thermal cured epoxy.PIN HOLES AND SCRATCHESAll coating of metal substrate for corrosion protection from automobiles to super tankers is subject to imperfections such as pin holes and scratches. Dili-gent adherence to mil spec quality procedures and careful handling minimizes these effects.DELIVERYA small quantity (10 to 50) of epoxy coated parts of all standard models are normally in stock for immediate delivery. Larger quantities of epoxy andPTFE coated parts are normally available within 4-6 weeks.HOW TO ORDERAll standard fluid flow and liquid level switch models with exposed metal surfaces are available with EPOXY or PTFE coating of these surfaces.Adding EC (epoxy coating) or PTFE to the end of a model number is all that is required.EXAMPLESUNCOATED MODEL NO: Q-1 / 3 / F COATED MODEL NO: Q-1 / 3 / F / EC COATED MODEL NO: L-30CR / A / PTFEUNCOATED MODEL NO: L-30CR / A WARRANTYThe Epoxy Coating No. 1201 & PTFE Coating No. 6060 are guaranteed to be applied per mil spec procedures.Coatings cannot be guaranteed to be free of pin holes and scratches, however all coatings are subject to written QC procedures and are 100% visuallyinspected for pin holes and scratches. All units with visible pin holes and scratches are rejected. 42 10-8-15

CHEMICAL RESISTANCE CHART FOR VARIOUS PUMP MATERIALSThe recommendations listed on the following pages are based upon information from material suppliers and careful examination of available informa-tion and are believed to be accurate. However, since the resistance of metals, plastics, and elastomers can be affected by concentration, temperature,presence of other chemicals and other factors, this information should be considered as a general guide rather than an unqualified guarantee. Ultimatelythe customer must determine the suitability of the pump used in various solutions.All recommendations assume ambient temperatures unless otherwise noted. The ratings for these materials are based upon the chemical resistance only.Added consideration must be given to pump selections when the chemical is abrasive, viscous in nature, or has a specific gravity greater than 1:1.How to use this chart: Column at left lists chemicals in alphabetic order. Columns at right list various pump materials, and their resistance to the chemicalsare rated by a letter code. Chemical Effect Ratings FOOTNOTES A – NO EFFECT - ACCEPTABLE 1. P.V.C. - Satisfactory to 72°F B – MINOR EFFECT - ACCEPTABLE 2. Polypropylene - Satisfactory to 72°F C – MODERATE EFFECT - QUESTIONABLE 3. Polypropylene - Satisfactory to 120°F D – SEVERE EFFECT - NOT RECOMMENDED 4. Buna-N - Satisfactory for “O” Rings * – NOT TESTED 5. Polyacetal - Satisfactory to 72°F 6. Ceramag - Satisfactory to 72°FThe performance comments and limitations listed above are supplied by Harwil Corporation for information only.
