1 Introduction
The VETUS electric diaphragm pump has been designed for use as
a pump for contaminated fluids (with large particles) such as waste,
shower and bilge water.
The pump is self-priming. Therefore it is possible to install the pump
at a higher position than the holding tank or above the bilge water
level.
Running dry of the pump is allowed. However, unnecessary running
dry will shorten the service life of both the motor and the diaphragm.
Always shut off all seacocks when leaving the ship.
Obstructions in pressure and/or suction hose may be harmfull
to pump and/or electric motor.
By using a fuse with the recommended amperage in the plus
cable, the fuse will blow if there are any blockages or when the
outboard shut-off valve is closed.
This will prevent damage to the pump or electric motor.
2.2 Flow direction
The desired flow direction relative to the foot determines how the
valves should be fitted.

2 Installation
2.1 Setting up
The space where the pump is installed must be dry and well venti-
lated.
When selecting a place for the installation enough room for carrying
out maintenance work must be kept in mind.
The pump can be mounted in all positions without impairing the
correct operation.
The pump is self-priming; the maximum suction height is 3-meter
(10 ft). It is recommended to install the pump below the minimum
fluid level in the holding tank. Possible contaminants, remaining in-
side the pump during stand-still, will then be flushed out easily dur-
ing the next operation of the pump.
When increasing suction height and/or head the capacity of the
pump will decrease.
Keep the length of the tubes as short as possible; a Iarger lenght of
the tubing will diminish the capacity of the pump.
Every bend, valve and connection in the system will also diminish the
capacity of the pump.
The maximum head is 5 meter (16 ft).
