Installing the electrical air valve

Operaon:

The pump head of the Jet Thruster system must be installed under the water line in order to prime this centrifugal pump. In some

limited cases of fast moving vessels a vacuum can be produced when the nozzles rise above the waterline and the intake remains

in the water. The sucon under the fast moving hull will retract the present water from the Jet Thruster system. When the boat

slows down or stops the water will automacally ow into the system due to the fact that the pump head and nozzles are under

the waterline.

However, it is possible that an air pocket can be trapped in the pump head prevenng the pump from self priming. In this unique

situaon an Electrical Air valve can be installed, this will release the present air from the pump head allowing the pump to rapidly

prime. Giving the operator immediate thrust pressure for maneuvering.

How to install the Electrical Air Valve:

A. Remove the winterization plug located on the pump outlet fitting.

B. Install the provided ⅛ hose connector.

C. Make sure to install the Electrical Air Valve above the waterline!

D. Apply the supplied exible hose and hose clamps between the pump unit and Electrical Air Valve.

E. Apply the supplied exible hose from the Air valve to outside of the vessel. In case of a technical failure,

water that comes from the pump unit when the Jet Thruster system is engaged, will be pumped outside the vessel.
