Franklin Electric E-Tech EG Instructions Pour L'utilisation page 12

Never use the electric power cable to
suspend the pump.
GB
In order to avoid the risk of mechanical or
electrical injury all portable pumps should be
securely isolated from electrical power supply
prior to their relocation.
Attach the power supply cable to the delivery pipe or
to the safety rope with cable clamps. The power
cable should not be taut: allow for a certain degree of
slackness to avoid the risk of strain caused by
expansion of the pipe during operation.

The automatic coupling system allows for quick and
efficient inspection operations.
The coupling foot is fastened to the bottom of the
sump together with the delivery pipe; two guiding
tubes connect it to the anchoring bracket secured to
the edge of the sump cover.
The pump is lowered along the guiding tubes until it
reaches the exact coupling position; the seal will be
tight thanks to the weight of the pump.
This operation can be repeated any number of times
and it makes checking and inspection operations
easier; the pump is simply extracted from the sump
by means of a chain (even if the system is flooded).
6.8 Electrical connection
Electrical connection must be carried out only
by a qualified electrician in accordance with
local regulations.
Follow all safety standards.
The unit must be always earthed, also with a non-
metallic delivery pipe.
Make sure the frequency and mains voltage correspond
with the name plate data.
For use in swimming pools (not when persons are in
the pool), garden ponds and similar places, a residual
current device with I∆N not exceeding 30 mA must be

installed in the supply circuit.
Install a device for disconnection from the mains
(switch) with a contact separation of at least 3 mm on
all poles.
When extension cables are used, make sure the
cable wires are of adequate size to avoid voltage
drops and that the connection stays dry.
6.8.1. Single-phase pumps
Supplied with incorporated capacitor and thermal
protector, with power cable type H07 RN8-F, with
plug and float switch.
Connect the plug to a socket with an earth lead.
Electrical diagram (paragraph 12.2 Annexes).
6.8.2. Three-phase pumps
Cable without plug.
Install in the control box an overload-protective devi-
ce in accordance with the name-plate current.
With three-phase pumps, when the water level is not
under direct visible control, install a float switch con-
nected to the control box and to set the water levels
to stop and automatically start the pump.

7 STARTUP AND OPERATION
Off
7.1 Preliminary checks before start-up of the
Do not start-up the device in case of damaged parts.
7.2 First starting
With a three-phase power supply make sure the
direction of rotation is correct.
Before installation, momentarily start the motor to
check through the suction opening that the rotation of
the impeller is as shown by the arrow on the pump.
Otherwise disconnect electrical power and reverse
the connections of two phases in the control box.
Operation with wrong direction of rotation will cause
vibration and loss of delivery capacity.
Reverse rotation can also demage the mechanical
seal.
When in doubt, take the pump out of the water and
check rotation of the impeller by sight.
The motors with supply current directly switched
by thermally sensitive switches can start automa-
tically.
Never take the pump out of the water while the pump
is still operating.
Avoid running dry.
Construction with float switch: the float switch
connected directly to the pump controls starting and
stopping.
Check that the float switch is free from any obstacle.
pump
Never introduce fingers in the suction
opening unless it is absolutely certain the
electric power has been disconnected (that
the pump cannot be accidentally switched on)
and the impeller has stopped rotating
completely.
