A good user manual
The rules should oblige the seller to give the purchaser an operating instrucion of Amtrol 420, 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 Amtrol 420 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 Amtrol 420. 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 Amtrol 420 should contain:
- informations concerning technical data of Amtrol 420
- name of the manufacturer and a year of construction of the Amtrol 420 item
- rules of operation, control and maintenance of the Amtrol 420 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 Amtrol 420 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 Amtrol 420, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Amtrol 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 Amtrol 420.
Why one should read the manuals?
It is mostly in the manuals where we will find the details concerning construction and possibility of the Amtrol 420 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.

This handbook will discuss the basic sizing used for our larger Well-X-Trol ® s such as WX-400, 420, 44 0, and 450 series. This allows you to use the Well- X-Trol ® “principle of separation of air and water” on larger jobs that are beyond the typical residential range. The Well-X-Trol ® models we’ll be working with in this handbook are lis[...]

-2- Utilizing the Maximum Capacity of Full Acceptance Well-X-Trol ® s Series 400, 420, 440 and 450 When used with conventional pressure ranges, these Well-X-Trol models use only a fraction of their maximum capacity. For Example: A WX-423 with a total volume of (275) gallons will accept the following: at 30/50 – (85) gallons or 30.9% at 40/60 –[...]

-3- For example, if we look at a typical pump curve for a ( 15) HP – (85) GPM submersible pump – we can sel ect a pump cut-in and cut-out point on the curve which will provide optimum pump operation. The pump curve shows pump performance as it s pressure rises from cut-off ( ( 0 ) head in test) to maximum head in feet. On this curve, for a (15)[...]

Subtracting the feet of head required for lift (240 ′ ) we can convert this point to PSIG: Maximum pump cut-out = 420 feet Less lift = 240 feet Maximum pressure = 180 feet To convert feet of head to PSIG, we divide by (2.31) (there is (2.31) feet of head for each PSI): 180 ÷ 2.31 = 77.9 or 78 PSIG. Or pump cut-out pressure (P3) is 78 PSIG. To Su[...]

-5- Step Three: Calculate Acceptance Factor (AF) Remember our formula for calculating the acceptance factor (AF) for diaphragm tanks? Step Four: Maximum Acceptance Factor Verification After calculating the acceptance factor (AF), we must compare the value to the maximum acceptance factors shown in Table 1. In the case of our example, an AF of 0.518[...]
