Ø
The connection for fresh water rinsing must be done with water from the pressurized
freshwater system.
Ø
A solenoid valve is mounted behind the prefilter for automatic rinsing.
Ø
The valve handle must be in seawater position (see diagram above with the 3
positions of the 3-way valve).
For manual rinsing, put the valve handle in fresh water position (see diagram above with the
3 positions of the 3-way valve) and follow the instructions in
Appendix A3
.
To replace the filter cartridge, follow the procedure in
Appendix A4
.
During this procedure, be careful not to lose the tank’s O-ring. Fill the system with fresh water
for 30 seconds to 1 minute before putting the valve handle back into the seawater position
(see diagram above with the 3 positions of the 3-way valve).
Connections
Ø
Use Tricoflex Ø 12mm (inside diameter) for the seawater system and for pressurized
rinsing.
Ø
Fasten two stainless steel collars on each connection, with the clamping heads
positioned opposite one another.
Ø
Connect the pressurized fresh water from the outlet of the water unit to the 3-way
valve.
Ø
Connection can be made under a sink, a washbasin or on the path of the pressurized
cold water piping.
Ø
The valve handle must be aligned with the filter.
Tip
: If the pipes are to pass through walls or be in contact with sharp corners, provide
protection against wear and friction by inserting them into a sheath or pipe of greater
diameter.
