INSTALLATION INSTRUCTIONS
HIGH PRESSURE PUMP
UNIT
Mount the high pressure pump unit in a cool and dry location, not higher than 30ft above low water level
at a distance not further than 100ft / 30m.
The electrical installation should only be done by a professional electrician. Check the correct
voltage before installing the system.
The “MAIN” marked cable is to be connected to the power supply. The smaller cable, marked “PUMP”
is to be connected to the raw water feed pump.
MEMBRANE VESSEL RACK
Mount the high-pressure membrane vessels with the provided brackets below the high pressure pump
unit. Vertical mounting is possible if space is limited but you will need to order different high pressure
hose lengths.
The membrane is sealed within its housing by plugs at both ends. Inside is a small amount of
preservative to keep the membrane moist and prevent bacterial growth.
It is important that this preservative does not evaporate and allow the membrane to dry out. If
this happens, the membrane will be destroyed.
The shelf life of the preservative, under best conditions, is one year. We recommend you install
and use your watermaker as soon as possible.
When all other components and hoses/pipes are completely assembled, remove the caps on the high
pressure fittings and the blue sealed tube from the product water outlet on the membrane housings, then
finish making all final hose/tube connections. This will insure that the membrane is kept moist until the
last possible moment before operation.
PRE-FILTER ASSEMBLY
Mount the pre-filter in a serviceable location and connect the intake port to the outlet of the raw water
feed pump or multi-media sand filter (optional). For short runs, use 5/8” reinforced PVC hose. For
longer runs, use a 5/8” or 3/4” PVC pipe. Connect the outlet of the pre-filter housing with a 3/4”
reinforced PVC hose to the intake of the high pressure pump.
INSTALL ALL PLUMBING TO ELIMINATE ANY AIR POCKETS IN THE SYSTEM
FRESH WATER FLUSH FILTER
Install the fresh water flush filter housing at a location near the seawater pre-filter assembly. Connect the
flush port of the three-way service valve at the pre-filter assembly with the outlet of the flush filter
housing (out). Supply pressurized fresh water to the shut off valve of the flush filter housing.
