This is a Lift/Amps/Flow Chart for the Flojet pump model used in the 24 Volt Submersible Pumps. For 12 Volt Pumps, the lift and GPM Flow is the same but the amperage rating is double.

GENERAL GUIDE TO INSTALLATION & OPERATION 

PREFACE: This document is intended as a general guide to understanding the installation and operation of the Submersible/Flojet Pump Unit. It does not contain complete information regarding safe and proper plumbing and electrical practice as well as information regarding the differing conditions of specific installations. If in doubt, proceed with caution and/or seek professional assistance. 
SYSTEMS - Typically, a storage tank, a pressure tank, or a combination of both (storage tank to booster pump to pressure tank) is part of a submersible pump water system. 
OTHER FACTORS include power source voltage and regulation, distance between power source and pump, and height between pumps and tank (head). 
Available power source voltage determines pump voltage. 
Distance between pump and power will determine gauge of electrical wire relative to pump amperage. (See Chart.) 
For longevity of small submersibles, use either a storage tank or combination system. 
EXAMPLE: 
Well depth..............................................60' 
Distance pump to power..........................65' 
Static water level..................30' below grade 
Level of pump.......................40' below grade 
Pump amps-volts.....................3.5 @ 24VDC 
Wire size.......................................12 gauge 
Height pump to tank.................................55' 
Tank type................storage w/float switch 
INSTALLATION PROCEDURE: 
1. Thoroughly read all literature included with the Pump. 
2. Lie out delivery pipe, electrical wires, and pump near wellhead. 
3. Connect one end of pipe to pump (use s.s. hose clamp). 
4. Install appropriate fitting at other end of pipe. 
5. Solder electrical wires to pump leads, or connect wires with uninsulated crimp connectors or other crimp connect device. Embed connection in marine sealant (3M 4200 or 5200 Fastcure or equiv.) and cover w/heat shrink tubes or other standard submersible pump wire splice seal device. Allow ample time for sealant to set prior to immersion. WARNING: Take Care! If this connection leaks your pump will fail. 
6. Bundle pipe and wire at 5' +/- intervals with cable ties and be sure that spliced wires at pump do not protrude beyond diameter of case. 
7. Lower pump into well to a point below static water level (1' to Maximum 20'). Note: A safety line is not required. 
8. Connect pipe from tank to pipe from well. 
9. Connect electric wires from tank switch to wires from pump. (Protect circuit w/10 - 12-amp fuse.) 
10.Review all procedures in thorough detail to determine if entire system and all plumbing and electrical connections have been installed and secured in complete accordance with professional standards. 
CAUTION: Only proceed with plumbing and/or electrical connections if qualified. Otherwise, seek advise of professional plumber/electrician. 
WARNING: Major damage to pump motor can result if pump is operated when water in delivery pipe is frozen or otherwise obstructed; the pumps are not equipped with bypass valves. 
OPERATION - To prevent pump damage or excessive wear, Pressure Tank Systems must be fitted with a pressure switch that switches pump off before total system pressure exceeds maximum rated pump pressure. Total system pressure is equal to the poss. of head (each 2.31of head = 1 poss.) plus poss. Of pressure switch shut-off setting. Total system pressure should not exceed maximum rated pump pressure (up to 100 poss. for standard Flojet pumps). 
To prevent overflow and excessive pump wear, a Storage Tank System (best system for small subs) must be fitted with a float or water level sensor switch. Being that a storage tank is not under pressure, total system pressure is simply equal to poss. 
Pumps operated direct from photovoltaic modules should be protected from excessively high voltage inputs via a manual or automatic disconnect switch at power source, and/or, an appropriately sized and compatible linear current booster (LCB) device. 
For proper operation of pump, electrical circuit must be suitably fused, grounded, and equipped with main disconnect switch at power source. 
APPROPRIATE USE: Our Pumps are primarily designed to efficiently supply potable water to off-grid remote site dwellings and for other low volume intermittent duty applications. Expected years of maintenance free service will be proportionately shortened if high volume continuous duty applications exceed the designed use. 
TROUBLE PREVENTION NOTE - Most pump failures are caused by improper installation and/or operation. Extra careful attention should be given to electrical wire connection and waterproofing, submergence depth, total system pressure, motor overload conditions, and under or over voltage inputs. 
(NOTE-The text above is the formal version of the installation procedure, with all the superfluous cautions, warnings, details, etc. In actual practice, the procedure is much simpler than this inflated document suggests. But please do read it; there are a few important points included that could spell failure if ignored.)

IMPORTANT! We need to know the depth of your well, and the depth to the water. No estimates please. It is important to the proper installation and operation of the pump. There is a 230-foot limit and a maximum operating pressure of 100 PSI only allowed.

ANSI/IEEE 62.41

In the power industry, transients from lightning strikes form the most powerful transient/surge electrical equipment has to deal with. The Institute of Electrical Engineers (IEEE) along with the American National Standards Institute (ANSI) developed a standard, dubbed 62.41 as a reasonable simulation for test of a lightning strike on electrical equipment.

This test, in essence, is to subject the device under test with 4,000 volts 8/20 uS combination surge with a 10,000 amp capacity directly on its terminal: both differential mode (across the terminals), and also common mode (either terminal to ground). All the while, the unit must be on and operating and suffer no degradation of performance.

The Power Tracker™ 30 amp unit passed this test as well as the 6,000 V common mode (either terminal to ground - usual lightning strike) requirement.

The Power Tracker™ user should feel secure some passing transient will not affect their system. If it passes the "direct" lightning strike test, local storms which have been known to fry some regulators won't affect it.

FCC

FCC Section 15J Part B (simplified)

The FCC is a U.S. federal commission that regulates the radio spectrum in the United States. Each region of the world has their own equivalent governing body.

They have published a number of requirements that any and all equipment must pass in order to be sold and manufactured in the United States. This is a "global" specification on all equipment that produces, either intentionally or unintentionally, RF (radio frequency) interference.

Testing of a product not only takes the form of measuring the radiated RF field strength around the unit, but also the RF conducted through each wire connected to the unit. All these tests view the RF spectrum from 10 KHz through hundreds of megahertz. So the testing is quite thorough.

The governing bodies have the authority to seize and impound equipment and property as well as impose fines if any product sold or manufactured in the United States does not conform to their specifications. This requirement is not to be taken lightly.

This is a time bomb in the solar field. The previous relay based controller had no RF, hence FCC impact. As PWM controllers and microcomputers are fairly new in this field, the issues of FCC compliance are raised.

The switching action of all PWMs, not to mention the microcomputers that control them, produce RF interference. Unlike safety UL type issues where there is little or no existing relevant specifications or guidelines, FCC certification is an enforceable existing real requirement as yet un-addressed in the solar power field.

This issue for PV systems is also made worse by the long lines and large PV panels that form a large radiating antenna. Not only does the potential exist for RF interference, but the PV wiring and array make an excellent antenna to broadcast it to the world.

The Power Tracker™ is certified to FCC Section 15J part B, the tightest and hardest to meet specification of FCC. Also it passes the specification by 20 db (a factor of 100). This effectively means unrestricted use of it in North America and effectively the world.
