INSTALLATION STEPS
We recommend that you install your pump in a clean and dry location where there is adequate room
for servicing at a later date. Protection from freezing temperatures and good ventilation should be
considered as well, to provide the pump an environment for long life. Locating the pump as close as
possible to the water source will reduce friction losses encountered in the suction pipe.
Friction losses in the suction pipe must be taken into consideration when the horizontal offset is greater
than 50 feet. The suction pipes should be increased from 1” to 1 1/4”. This will reduce friction losses and
allow the pump to give maximum performance.
A new well should be checked to determine that it is free from sand. Sand will damage the seal and the
impeller. Have your well driller clean the well before your installation.
Never run the pump dry. Damage to the seal may occur. Fill pump body and suction pipe with water
before turning on the power.
THE RUN OF HORIZONTAL PIPE FROM THE TOP OF YOUR WELL INTO THE HOUSE, WHERE
YOUR PUMP WILL BE LOCATED, MUST BE INSTALLED IN A TRENCH, BELOW THE FROST LEVEL
OF YOUR AREA.
STEP 1
Your ejector is factory pre-assembled with the venturi
510066.2, for an optimum performance when the
pumping level is between 25’ to 60’ (7.5 meters to 18
meters) depth, in reference to the pump position.
So, this is a deep well application mode. The ejector is
positioned into the well and is connected to the pump
using 2 pipes (see page 5).
If the pumping level is deeper than 60’ (18 meters)
in reference to the pump position, it is mandatory to
unscrew the pre-assembled venturi and to replace it
by the venturi 510066.3, also as a deep well mode
application with the ejector positioned into the well.
In the case of a pumping level lower than 25’ (7.5
meters), unscrew the pre-assembled venturi and replace

it by the venturi 510066.1. Then screw the
ejector to the pump body. This becomes a shallow well mode application where only one pipe is required
to pump water (see page 4).
