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.

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.
