A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of A.O. Smith 705 Series 100, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of A.O. Smith 705 Series 100 one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.

Unfortunately, only a few customers devote their time to read an instruction of A.O. Smith 705 Series 100. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.

What should a perfect user manual contain?

First and foremost, an user manual of A.O. Smith 705 Series 100 should contain:
- informations concerning technical data of A.O. Smith 705 Series 100
- name of the manufacturer and a year of construction of the A.O. Smith 705 Series 100 item
- rules of operation, control and maintenance of the A.O. Smith 705 Series 100 item
- safety signs and mark certificates which confirm compatibility with appropriate standards

Why don't we read the manuals?

Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of A.O. Smith 705 Series 100 alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of A.O. Smith 705 Series 100, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the A.O. Smith service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of A.O. Smith 705 Series 100.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the A.O. Smith 705 Series 100 item, and its use of respective accessory, as well as information concerning all the functions and facilities.

After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

    In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturer’s instructions for installation of the valves. Before[...]

    Closed System/Thermal Expansion CAUTION - PROPERTY DAMAGE HAZARD As water is heated, it expands (thermal expan- sion). In a closed system, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pres- sure due to thermal expansion. Thermal expan- sion can cause premature tank failure (leakage). T[...]

    Temperature and Pressure Relief Valve For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening on the on-demand storage tank. This valve must be design certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of listed eq[...]

    8 W a ter Quality and Scale A complete water analysis and an unde rstandi ng of system requirements are needed to protect the on-demand water heaters and water heating systems from scale. Water analysis shows whether water is hard or soft. Hard water, unless treated, will cause scaling or liming of the heat exchanger. The rate of scaling increases [...]

    9 Pump Sizing for Circulation 1. Use the chart below or one appropriate for your con ditions to determine the heat loss in the length of the hot water supply and return piping. For example, 100 ft of 1-1/2 in bare copper tubing results in a heat loss of 5300 Btu/h. 2. Determine the acceptable temperature drop at the last fixture in the loop. For ex[...]

    The following applies when using on-demand water heaters to recover a storage tank. Drawing H-1-TC is an example. On-Demand water heaters have a pressure loss which must be considered in the system design.
