COMPONENTS REQUIRED FOR
CORRECT INSTALLATION
13
Control panel equipped with a main switch and thermal
•
relay for overload protection.
Non-return valve at 10 meters' distance from the delivery
•
ports, plus an additional non-return valve every 30÷50
meters of piping.
Gauge and gate valve at well mouth.
•
Electronic probes or floats for protection against dry
•
running.
Secure the drop cable to the pipe every 2÷3 meters of
•
piping.
Make sure the electric pump is installed at a safe
•
distance from the bottom of the well.
Make sure there is a minimum distance of 3 mm
•
between the diameter of the pump and the internal
diameter of the well.
During operation, make sure that the water circulation
•
speed around the motor is at least 8 cm/sec.
Make sure that the minimum dynamic level of the water
•
in the well is at least 1 m above the pump's delivery port.
