Franklin Electric ESP50AM Mode D'emploi page 2

Before installation, check your local electrical and
plumbing codes. These regulations are for your
safety.
1) location: The pump should be installed in a location
that:
a) Has adequate room for servicing.
b) Is protected from freezing.
c) Will require minimal piping to keep friction losses
as low as possible.
2)
warning
- risK of electrical shocK
All installations must be made into a grounded
outlet. A ground fault interrupter (GFI) protected
circuit is recommended for use with any electrical
appliance operating in or near water. For installa-
tions consult a licensed electrician.
Make sure the line voltage and frequency of the electri-
cal current supply match the specifications printed on
the pump nameplate. The ground terminal on the plug
is provided for your protection. Do not remove.
Plug the pump cord into a grounded service and con-
nect the discharge piping, your pump is then ready for
operation.
3) sump preparation requirements:
a) level bottom - can be levelled with bricks.
b) size: minimum 24" deep x minimum 18" diameter
(For vertical float switch models the minimum
sump diameter is 14".)
4) float switch: (where applicable)
The float switch (if so equipped) is sealed and factory
adjusted to be suitable for most sumps. Be sure that
the float has adequate clearance and cannot become
stuck on the sides of the sump. Do not allow the power
cord to interfere with the free movement of the float
or to drape over the motor housing. The power cord
should be taped to the pump discharge piping with
electricians tape.
note: For "piggy-back" style float switches the range
of pumping levels can be varied by adjusting the free
length of cable between the float switch and the cable
clamp. The free length of cable must be at least 4" to
allow free movement of the float. Longer free length
allows a larger pumping range. Always check opera-
tion of switch after making any adjustments!
5) discharge piping:
a) The pump has a threaded discharge opening.
b) PVC or ABS adapters may be used to adapt to
other sizes of pipe.
c) We recommend that you not reduce the discharge
pipe size, use as large as possible.
d) Keep piping length to a minimum (extra length
increases friction losses).
e) A check valve must be installed for proper instal-
lation.

6) operational check: (never operate pump dry)
Upon installation manually fill the sump to check the
float switch operation. Ensure the start and stop levels
are satisfactory and the float has adequate clearance
to the sump sides. While the pump is operating check
that all connections are tight and are not leaking.
important: To avoid freezing in the discharge line
during cold weather operation drill a 1/4" hole in the
discharge pipe above the check valve in sump pit. This
will allow any liquid in the discharge pipe to drain back
into the sump pit and avoid freezing.
If the back flow of water in the discharge pipe causes
the pump to turn on again, then the length of the dis-
charge pipe needs to be reduced.
