B – THE LP PUMP
1 – LP PUMP INSTALLATION
The booster pump must be installed 200mm below the water line, between the hull valve and the filter 5µ (as indicated in Fig. installation on
board in Appendix). There should be no air accumulation.
Only use the pipe provided by SLCE respecting the diameters and type of hose (see installation drawing board 111121-08).
If the pump is placed too far or too high compared to the hull fitting, cavitation is possible. Cavitation produces jangling that might completely
destroy the pump. The LP pump must be installed horizontally and or vertically (provided it is below the engine).
This type of LP pump prohibits operation without water. The pump must be installed below the water line, between the hull valve
(V0) and the filter 5µ (4).
Some examples of LP pump installation:
- The pump is imperatively at 200 mm below the water line,
- The hull valve (V0) should be placed below the LP pump,
- The rising line should be installed above the LP pump, so as to avoid air accumulation or trapped air.

2.1 – MAINTENANCE OF THE PUMP
The only required maintenance of the pump, is to flush it with fresh water during cleaning operation of the unit.
For a long term stop, it is necessary to store the PROCON pump (with glycerin), see Technical Note NT0809 (end of manual).
NB : A rinsing operation of the LP pump-barrel with fresh water before a 3 day operating stop or longer considerably increases the life of the
LP pump.
