VI. Assembling the System (Photos Below)
1. Disconnect tubing from the membrane
housing cap, unscrew the cap and
check the o-rings to ensure they are it
working order.
2. Unwrap the Reverse Osmosis
Membrane and install it into the
membrane housing, ensure that you
only handle the membrane by the
end stems as shown. The
membrane is inserted firmly o-rings
first. Replace the membrane cap –
be careful to keep the o-rings lined
up correctly to avoid pinching them if
they fall out while tightening.
3. Firmly hand tightening the cap is usually sufficient, the opening
handle membrane attachment can help nip up the housing further if
required.
4. Unscrew the vertical pre filter housings and unwrap the internal
cartridges – maintain minimal contact with the surface of the carbon
filter, handle by the end caps only to avoid contamination
5. Screw up the housings while they are in a vertical position to ensure
the cartridges remain cantered until you begin to feel resistance. (if
you gently shake the housing you should not be able to feel/hear the
cartridge rattle inside. Hand tightening these housings is generally
enough to seal them due to the dual tapered o-ring seal of the
housings. Only use the opening spanner if the housings need to be
tightened further to avoid leaks. DO NOT over tighten the housings
– doing so causes stress on the caps and may cause a split or crack
causing potential flooding.
NOTE: The rim of the housing and the cap should not be touching –
this is too tight. The gap should be approx. 3 mm – 4 mm between
the cap and the rim of the housing.
You are now ready to connect the system.
