INSTALLATION

The pump must be fitted in a well ventilated place, protected from unfavorable weather
7.1
conditions and with an environment temperature not exceeding 104 °F (40°C). Fig.B
A firm anchoring of the pump to the bearing surface favors the absorption of any vibrations
7.2
caused by pump operation. Fig. C
7.3 Ensure that the metal pipes do not exert undue strain on the apertures, thus preventing
deformations or breakages. Fig. C
7.4 It is always good practice to place the pump as close as possible to the liquid to be pumped.
The pump must be installed only in horizontal position. The internal diameters of the pipes must
never be smaller than that of the mouth of the pump. It is advisable to fit a foot valve on suction.
Fig. D For suction depths of over 13ft (4 m). or with long horizontal stretches it is advisable to use
an intake hose with a diameter larger than that of the intake aperture of the pump. To prevent the
formation of air pockets, the intake hose must slope slightly upwards towards the pump. Fig. D
If the intake pipe is made of rubber or flexible material, always check that it is of the reinforced
7.5
type to avoid throttling due to suction.

ELECTRICAL CONNECTION

Caution! always follow the safety regulations.
8.1 All electrical work should be performed by a qualified electrician in accordance with the
latest edition of the National Electrical Code, local codes and regulations.
8.2 In fixed installations, International Safety Standards require the use of isolating switches with a
fuse-carrier base.
8.3 Single-phase motors are provided with built-in thermal overload protection with automatic reset,
and may be connected directly to the mains.
Please follow the wiring diagrams inside the pressure box.
Ensure that the mains voltage is the same as the value shown on the motor plate.
A faulty motor or winding can cause electrical shock that could be fatal, whether
touched directly or conducted through standing water. For this reason, proper
grounding of the pump to the power supply's grounding terminal is required for
safe installations, the above-ground metal plumbing should be connected to the
power supply as a ground as described in Article 250-80 of the National
Electrical Code or Section 26-954 of the Canadian.
