The function of the tank is to store a 
quantity of water under pressure. When 
full, the tank contains approximately 
2/3 water and 1/3 compressed air. The 
compressed air forces the water out 
of the tank when a faucet is opened. 
An air volume control automatically 
replaces air lost or absorbed into the 
water. The usable water, or draw-down 
capacity, of the tank is approximately 
1/6 of the tanks total volume when 
operated on a “20-40” pressure setting 
(Figure 2).

A pre-charged storage tank has a 
flexible bladder or diaphragm that acts 
as a barrier between the compressed 
air and water. This barrier prevents the 
air from being absorbed into the water 
and allows the water to be acted on by 
compressed air at initially higher than 
atmospheric pressures (pre-charged). 
More usable water is provided than 
with a conventional type tank. Pre-
charged tanks are specified in terms 
of a conventional tank. For example, 
a 20 gallon pre-charged tank will have 
the same usable water or draw-down 
capacity as a 40 gallon conventional 
tank, but the tank is smaller in size 
(Figure 2).

The pressure switch provides for 
automatic operation. The pump starts 
when pressure drops to a cut-in setting. 
The pump stops when pressure reaches 
a cut-out setting.

12.Do not run the pump dry or damage 

will occur and will void warranty.

13. For maximum safety, the unit should 

be connected to a grounded circuit 
equipped with a ground fault 
interrupter device.

14. Before installing the pump, have 

the electrical outlet checked by a 
licensed or certified electrician to 
make sure the outlet is properly 
grounded.

15. Make sure the line voltage and 

frequency of electrical current supply 
agrees with the motor wiring.

16. Do not attempt repairs to the 

electric motor. All repairs to the 
motor must be completed at a 
licensed or certified electrical motor 
repair shop.

17. Avoid kinking electrical cord 

and protect electrical cord from 
sharp objects, hot surfaces, 
oil and chemicals. Replace or 
repair damaged or worn cords 
immediately.

18. Keep fingers and foreign objects 

away from ventilation and other 
openings. Do not insert any objects 
into the motor.

19. To reduce the risk of electrical 

shock, the pump should be plugged 
directly into a properly installed 
and grounded 3-prong grounding 
type receptacle, as shown in 
Figure 1. The green (or green and 
yellow) conductor in the cord is the 
grounding wire. The motor must be 
securely and adequately grounded 
for protection against shock.

20. Where a 2-prong is encountered, 

replace the plug with a properly 
grounded 3-prong receptacle in 
accordance with the National 
Electrical Code, local codes and 
ordinances. To ensure a proper 
ground, the grounding means must 
be tested by a licensed or certified 
electrician.

21. Use only 3-wire extension cords that 

have a 3-prong, ground type plug, 
and 3-pole receptacles that accept 
the equipment plug.

22. Use wire of adequate size to 

minimize voltage drop at the motor.

The water supplies illustrated in Figure 
26 are possible sources for water. These 
water supplies can be divided into two 
categories:

SURFACE WATER

Water from a lake, stream, pond and 
cistern. This water is usually not fit 
for human consumption, but may be 
suitable for washing, irrigation or other 
household uses.

GROUND WATER

Water found in the water bearing 
stratum at various levels beneath the 
earth. Of all the fresh water found on 
earth only 3 percent is found on the 
surface and 97 percent is underground.
