Arizona Solar Plumbing, Liquid Systems Only Residential / Commercial Contractor (CR-78) Highlighted & Tabbed Books Allowed into Exam Package

Prepare for the Arizona Solar Plumbing, Liquid Systems Only Residential / Commercial Contractor (CR-78) exam with a coordinated set of reference books prepared for efficient exam-room use. This package includes the six listed publications with highlighting and permanent tabs designed to help you locate important code sections, trade information, formulas, safety requirements, installation guidance, and technical references more efficiently during an open-book contractor examination.

Contractor exams can require more than simply understanding the trade. Candidates must also know how to work with multiple reference books under time pressure. A person may understand solar plumbing systems, piping methods, jobsite safety, and mechanical principles but still lose valuable time searching through unfamiliar chapters, indexes, definitions, tables, and appendices. Highlighted and tabbed books create a more organized reference system so you can move between publications with greater confidence.

This package is designed for candidates pursuing the Arizona CR-78 Solar Plumbing, Liquid Systems Only residential and commercial contractor classification. The included references address plumbing and mechanical codes, construction safety, trade mathematics, piping practices, and solar water or pool-heating system design. Together, they provide a structured library for studying the technical concepts associated with liquid-based solar plumbing work.

The books are prepared with permanent tabs that identify useful chapters and major subject areas. Important material is highlighted to make key provisions and commonly studied information easier to recognize. Highlighting and tabs do not replace studying, trade experience, or careful reading. They serve as navigation tools that help candidates use their approved references more effectively during preparation and on exam day.

Because each publication is organized differently, candidates should practice using the books before the examination. Learn where definitions are located, how chapters are arranged, what information appears in tables, and how each index directs you to relevant material. Familiarity with the books can reduce unnecessary searching and help you make better use of the time available during the test.

Exam Details

The Arizona CR-78 examination is associated with the Solar Plumbing, Liquid Systems Only residential and commercial contractor classification. Preparation should combine practical trade knowledge with the ability to research answers in approved reference materials. Candidates should be comfortable identifying the correct publication for a question and moving quickly to the applicable chapter, section, table, formula, illustration, or definition.

Study should include the relationships among plumbing requirements, mechanical requirements, workplace safety rules, mathematical calculations, piping principles, and solar thermal system design. Questions may require direct code research, interpretation of technical language, application of trade knowledge, or calculation-based problem solving. Effective preparation therefore involves both reviewing the material and practicing how to find it.

Begin by learning the purpose of each book. The plumbing code should be your primary resource for plumbing-system provisions, materials, system components, installation requirements, and related definitions. The mechanical code addresses mechanical systems and technical requirements within its scope. The OSHA publication focuses on construction safety. The mathematics reference supports calculation practice, while the pipe trades handbook provides field-oriented technical information. The solar design and installation manual addresses concepts specific to solar water-heating and pool-heating systems.

During study sessions, avoid relying only on memorization. Practice reading a question, identifying its subject, selecting the correct reference, and locating the answer. This routine helps develop the research habits needed for an open-book exam. Repeated use of the same tabs, chapter headings, indexes, and highlighted passages can strengthen familiarity with the complete book set.

Open Book Test

This package contains books identified for use in the exam room for the Arizona CR-78 Solar Plumbing, Liquid Systems Only contractor examination. Open-book testing allows candidates to consult approved references, but it still requires preparation. There may not be enough time to research every answer from the beginning, so candidates should enter the exam with a working understanding of the trade and a clear navigation strategy.

Permanent tabs can help you reach major sections without repeatedly searching the table of contents. Highlighting helps important material stand out when reviewing a page. The strongest results come from combining these features with consistent practice. Work with the exact books you plan to use during the examination so their organization becomes familiar.

As you study, assign each subject to its most likely reference. Safety questions should direct your attention to 29 CFR Part 1926. Plumbing provisions should lead you to the International Plumbing Code. Mechanical-system requirements should point toward the International Mechanical Code. Calculations should suggest the mathematics reference, while piping data and field information may be found in IPT’s Pipe Trades Handbook. Solar-specific questions should direct you to the Solar Water and Pool Heating Design and Installation Manual.

Tabs and highlighting must be used as navigation aids rather than shortcuts around learning the material. Read surrounding sections carefully because code questions may depend on definitions, exceptions, conditions, notes, or related provisions. When a highlighted sentence appears relevant, review the complete section before selecting an answer.

Licensing Steps

Arizona contractor licensing is administered through the Arizona Registrar of Contractors. Applicants pursuing the CR-78 classification must complete the licensing requirements applicable to their business entity, classification, and qualifying party. The licensing process is separate from purchasing exam-reference materials and may include an application, examinations, business documentation, financial or bonding requirements, background information, and other items required by the state.

A practical licensing plan begins with confirming the correct classification. The CR-78 classification applies to Solar Plumbing, Liquid Systems Only work within its authorized residential and commercial scope. Applicants should review the classification description and determine whether it matches the work the business intends to offer.

The next step is identifying the qualifying party who will satisfy the experience and examination requirements associated with the license. The qualifying party should prepare for all required examinations and ensure that their experience documentation accurately reflects qualifying work. Business owners should also organize entity records and other application materials so the licensing submission is complete and consistent.

After completing the required examinations, the applicant must continue through the state’s licensing process. Passing an exam does not by itself create a contractor license. The license is issued only after the Arizona Registrar of Contractors accepts the application and determines that the applicant has satisfied the applicable requirements.

Applicants should use current instructions and forms when completing the process. Names, business records, qualifying-party information, and supporting documents should match throughout the application. Missing or inconsistent information can delay review, so careful preparation is important.

State Requirements

The Arizona CR-78 license is a regulated contractor classification. Candidates should understand that examination preparation is only one part of becoming licensed. The applicant must satisfy the state requirements that apply to the license classification and business structure.

State requirements may address the qualifying party’s experience, examinations, application documentation, business entity information, bonding, fees, and other licensing conditions. Requirements can differ depending on the applicant’s circumstances. Candidates should complete every item required for the CR-78 application rather than assuming that an exam score is the final licensing step.

The qualifying party has an important role in demonstrating trade knowledge and experience for the classification. Experience records should clearly describe relevant responsibilities and work. Applicants should also maintain accurate legal and business information, including the entity name used on the contractor application.

Once licensed, contractors are responsible for operating within the authorized scope of the classification and following applicable laws, codes, safety requirements, permit conditions, and professional standards. The license does not authorize work outside the classification’s permitted scope. Contractors should understand where CR-78 authority begins and ends before advertising or accepting projects.

Local jurisdictions may also enforce adopted construction codes, permit procedures, inspections, and project-specific requirements. Exam preparation should therefore build a strong foundation in code research and technical understanding that can continue to support responsible field practice after licensing.

Test Information and Study Materials

A productive CR-78 study plan should divide preparation into manageable subject areas. Begin with plumbing and mechanical code organization. Review the table of contents, definitions, chapter arrangement, indexes, tables, and appendices. Practice locating information by topic rather than reading each code only from beginning to end.

Next, review construction safety. Become familiar with how OSHA construction standards are arranged and where major jobsite subjects appear. Safety questions often require distinguishing between similar requirements, so read the complete applicable provision and pay attention to conditions or exceptions.

Trade mathematics should be practiced with a calculator and written steps. Review measurement conversions, fractions, decimals, percentages, ratios, geometry, area, volume, and piping calculations. Do not simply read solved examples. Work through problems independently, check the answer, and identify the step where an error occurred.

Use IPT’s Pipe Trades Handbook to become comfortable with field data, formulas, dimensions, and piping information. Since handbooks contain dense technical material, tab familiarity is especially useful. Practice finding a particular formula or table and then applying the information to a sample problem.

Solar thermal study should include system components, fluid circulation, collectors, storage, controls, heat transfer, installation practices, system protection, and troubleshooting principles covered by the provided manual. Focus on how components work together rather than treating each part as an isolated term.

Complete timed practice sessions using all six references. Place the books in a consistent order and return each one to the same position after use. This simple routine can reduce confusion during the exam. Mark difficult subjects for additional review and repeat the research process until you can locate the applicable material efficiently.
