In order to keep the voltage drop in the cable as low as possible and to avoid dangerous heating of
the cable, it is necessary to carefully determine the required cable cross-sections. The voltage (V) drop between
current source and consumer must not exceed the following values:
Navigation lights: 5% in 12 V on-board network = 0.60 V Other consumers: 7% in the 12 V on-board
network = 0.84 V
Since the current has an outward and return path through 2 cores, the length of the conductor is always
as long as the cable length. The constant conductance of copper is 56.

When you change the pump from manual to electric, the inlet and outlet tubes are the same, although of different sizes. The water inlet pipe has an arrow indicating the direction of water flow indicated on the pump. The outlet tube you must put an adapter to get the size of the outlet tube.
On the side you cannot see on the photos there is the inlet for fresh water (saltwater). On the other side is a black hose connection where the white hose (comes with the delivery) you connect with the hose connection in the bowl for flush water. Below the black connection is a white triangular formed connection where you connect the waste hose.
I've installed the toilet. It is located aprox 2m below holding tank and 40cm above water line. I also installed a goose neck throught the inlet. When i pump all water out, by closing the inlet seacok, few hours later i find water in the toilet.
Do i need also a check valve on the outlet side?
Dear Rodrigue, is that right, that you got a goose neck only for the fresh water, but not for the waste? Please have a look at our article -30133- You need a goose neck for the waste as well. / Your SVB-team.
La prise d'eau doit être raccordée. Je dirigerais la sortie de votre pompe existante vers le kit de conversion et alimenterais l'entrée d'eau des toilettes à partir de là. J'ai connecté le kit de conversion à un système d'eau sous pression. Cela fonctionne parfaitement.
question related to OCEAN TECHNOLOGIES Toilet Conversion Kit:
the rinse water inlet to the pump from the seacock, which side of the electric motor is it?
is it on the the same side of the waste outlet or the opposite side?
I am asking this question as the flow arrow marked on the housing of the pump is confusing me.
Dear Marialberto, the flow arrow is for the dishwater. So the intake side for the dishwater is the same side like the outside for the sewer pipe. This is logical for one reason, the thru-hulls are always one the same boatside, just on different heights. Hope we could help you. Your SVB-team.
