10. Installing the pump

10.1 Installation depth

The dynamic water level should always be above the 
pump, see fig. 10.
A = Dynamic water level 
B = Static water level 
C = Minimum 3 inch well diameter 
D = Drawdown 
E = Installation depth below static water level.

Maximum 500 feet.

Installation depth

Procedure:

To install the pump, proceed as follows:
1. Attach the enclosed data plate sticker at the well 

head.

2. Check the well for proper clearance. The well must 

be at least 3 inches in diameter. It is a good idea to 
check the well for clearance using a plumb ring 
(2.95 ø x 10 in.). 

3. Attach the first section of riser pipe to the pump. 
4. Lower the pump into the well. Make sure the mo-

tor cable is not damaged when the pump is lifted 
or lowered into the well, especially in 3 inch wells.

Note:

 Do not lower or lift the pump using the mo-

tor cable. 

5. When the pump has been installed to the required 

depth, the installation should be finished by 
means of a well seal. 
Note that the dynamic water level should always 
be above the pump.

6. Loosen the safety wire so that it becomes un-

loaded and lock it to the well seal using a cable 
clamp.

7.

Complete the electrical connections.

Note: 

The pump must never be connected to a capaci-

tor or to another type of control box than CU 300 or 
CU 301. 

Installation depths:

Maximum installation depth:
500 feet below the static water level. 
Minimum installation depth:
1.75 feet below the dynamic water level.

Vertical installation:

During start-up and operation, the pump must always 
be completely submerged in water.

Horizontal installation: 

The pump must be installed at least 1.75 feet below 
the dynamic water level. 
If there is a risk that the pump might be covered by 
mud, the pump must always be placed in a flow 
sleeve.

Note:

 Do not lower or lift the pump using the motor 

cable. 

11. Generator operation

It is safe to operate the SQ/SQE with a generator.
The generator must be sized 50% above the P1 (input 
power) values of the pump. See the following table.
