Installation guide page 1

 

 

Caution:

  

 

Hose connections below the water line should secured with 2 hose clamps. 
All hose clamps must checked time to time and tighten if need. 
During assembly of the hose nozzles and fittings, few windings of Teflon-tape have to 
be wrapped around the screw thread  against screw direction as tightly as possible. 
The grommets may not be screwed too tightly in the filters or stop-cocks. If possible, 
install hoses moved upward from the thru-hull fitting to the filters and up to the high-
pressure pump. This will prevent accumulation of air in the hoses.  

 

Thru-hull fitting, Strainer and feed pump 

 

The thru-hull fitting, coarse filter and the feed pump have to be located in an area that 
will  always  be  under  the  waterline  when  the  boat  is  used  under  normal  running 
conditions. Install the feed pump close as possibly to the thru-hull fitting. 
Install  a  thru-hull  fitting  and  sea-cock,  preferably  deep  under  water  line.  The  best 
place is about amid-ships behind the keel.  
Install  afterwards  a  coarse  filter  for  protection  the  feed  pump.  To  avoid  mechanical 
stress, do not mount the strainer directly to the sea-cock. 

 

The  feed  pump  must  be  flooded  before  turn  on,  otherwise  the  bearings  will  be 
destroyed by drought. The system has to be fully de-aerated by means of the feed 
pump. To allow any air to escape, switch the pump on and off few times and open air 
release valve at pre filter. 

 

Note:

  

 

Depending on the type of boat, there might occur problems with the seawater intake 
at a speed of more than about 8 knots. 
Depending on the used thru-hull fitting, hull shape and speed, the inflow of seawater 
can be hampered or even be impossible. Damages to the plant due to insufficient or 
missing seawater inflow will not be covered by the warranty or guarantee. 

 

Caution:

  

 

Do not connect the feed pump directly to a filter housing, tap or similar. 

Only connect to other components with the enclosed hose nozzles and hose.  
The following installation position must be observed in order to make it difficult to set 
deposits and to allow the escape of air.
