make sure to install the check valve before
installing the hose and ports. The check
valve for the [1 1/8” or 1 ¼”] model will
include a stainless steel washer and a flap-
per. To install the check valve, place stain-
less steel washer into the discharge area
of pump. Next place the Nitrile flapper over
the washer. Then thread on the port on to
pump’s discharge. Tighten port until port
is bottomed out with pump body.
For ¾” model install check valve such that
the tapered end is towards the direction of
flow. To install check valve, remove gasket
in Duraport and replace the gasket with the
check valve which also acts as the gasket.
Save the old gasket in case you intend to
not use the check valve at a later time.
Make sure to avoid loops or bends in the
hose. Support hose if necessary. It is im-
portant that the hose be constantly rising
and not be allowed to dip below the outlet
port as this may cause an airlock situation.
For maximum performance use smooth
bore, reinforced hose.
NOTE:
The check valve supplied with your
Ultima Bilge pump is used to prevent the
backflow of water. The utilization of the
check valve requires you to be mindful of
its functionality. The check valve material is
made of Nitrile material to be used for wa-
ter applications only. Also, the check valve
will reduce the flow of the pump. If flow is
critical to the application of the pump, it is
recommended that the check valve not be
used. Also, when winterizing your boat, re-
move the check valve to avoid ice formation
and/or degradation of the check valve.

Wiring Instructions:
Refer to wiring diagram below. Use appro-
priate sized connectors for 16 Gauge wire.
The wiring connections should be made
with water resistant permanent terminals.
Liquid electrical tape should be used to
coat terminals. The mount connections
should be above the highest water level.
The warranty will become void on this
product if any electrical cord is cut back
more than 3 inches, if electrical splices be-
come submerged, failure to properly fuse
or if pump is installed contrary to instruc-
tions or warnings.
You may install a three way switch panel
that will allow the pump to be in manual
or automatic mode. Make sure to fuse
the pump. The fuse holder should be be-
tween positive battery terminal and three
way panel switch. Make sure to use the
appropriate fuse size for the models. To
check the operation of the pump, place
two fingers over the raised circular areas in
the back of the pump. After a short delay
[5 seconds], the pump should turn on. If
you remove your finger from the top circle,
the pump should remain on. If you remove
both fingers, the pump should turn off.
