Specifications

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.
HIGH PRESSURE HOSE
Never bend the high pressure hose tighter than a 4”/10cm radius.
Run one of the high-pressure hoses from the outlet of the HP pump (O ring sealed fitting) to the O ring
sealed fitting at the end of the membrane that is marked “IN”.
A minimum hose length of 3 feet / 1m is required for pulsation dampening. The hose can be coiled
where needed.
Run the second high-pressure hose from the flow control box to the O ring sealed fitting at the end of the
membrane that is market “OUT”.
CAUTION: WHEN CONNECTING THE HIGH-PRESSURE HOSE TO THE MEMBRANE
HOUSING(S), AVOID OVERTIGHTENING. THE FITTING IS O-RING SEALED AND DOES
NOT REQUIRE MUCH TORQUE.
PRODUCT WATER TUBING
Connect the blue product water tubing (for longer runs than 10ft / 3m on the models 1200 and larger, use
a 1/2" PVC hose or pipe) from the center fittings of the membrane housing(s) to the inlet of the flow
control panel. Connect the tubing or hose from each output port of the flow control panel to your fresh
water storage tank/s and to a taste/test station of your choice.
Do not allow the product line to become blocked while the system is running. It must be avoided
that chlorinated water from your storage tanks can flow back into the RO membranes. Therefore,
the product discharge must be above the tank’s waterline.
HARDENER / pH NEUTRALIZER KIT
Install the hardener / pH neutralizer housing at a serviceable location in line with the product water
tubing from the diverter valve on the control panel to the freshwater storage tank. Observe the flow
direction indicated on the housing.
REJECT WATER TUBING/HOSE
Connect the outlet of the pressure control valve on the back of the flow control panel with a 1/2”
reinforced PVC hose to a thru hull preferably above the waterline.
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.
