Determine Installation Location
Space:
Make sure there is sufficient space under the counter for installation (an area of about
16”L x 6”W
x 18”H
for the system,
11”D x 18”H
for tank).
The RO system is best installed under the kitchen sink. But if that is not feasible you can install the system
anywhere where there is a cold water supply with sufficient water pressure for the chosen RO model, and
an outlet to drain off the drain water from the system.
Avoid locations where the system might come in
contact with hot water pipes or other hazards.
Mounting:
No need to mount the RO system on the wall. The RO system can stand in the sink cabinet
without mounting, this makes future filter change easy and convenient. If you prefer to mount the system to
the wall, please make sure it can be taken down easily for filter replacement.
Determine the location of the cold water
feed line to use for the system supply.
Notice:
Accidentally hooking up the system to the hot water supply line will permanently
damage the membrane (see conditions for operation). To assure you are using the
cold water line, turn on both the hot and cold faucet. After the water is warm to the
touch, feel the pipes under the sink. It will be easy to identify the hot and cold pipes.
Determine the location for the faucet. Check to see that drilling the faucet hole will not damage pipes or
wires running underneath the sink.
Determine the location for the storage tank. A maximum distance from tank to faucet of 15 feet is possible
(additional tubing will be needed). The system will produce a faster flow at the faucet with the shortest
tubing run from tank to faucet. The storage tank can lay on its side if needed.
Assemble Filter Housings onto
System
Manifold
Note: The RO Membrane Element has already been pre-installed
Remove plastic/paper wrappings on the 3 filters and housings, put filters into the 3 housings, and assemble the
housings onto the main system as follows:
1. Stand the 3 housings upright. Make sure each housing has a rubber O-ring in its groove.
2. Put the sediment filter into the “1st stage” housing on the right. Put the CTO filters into the “2nd and
3rd stage” housing in the middle and left.
3. Starting from the 3rd stage housing on the left, hand twist the housing onto the main system turning
counterclockwise, one by one, for all 3 housings.
4. Use the wrench provided to completely tighten the housing starting from 1st-stage. Repeat this step
for the 2nd stage housing in the middle, and for the 3rd stage housing on the left.
Note
:
For some people it is easier to use the wrench with the system laid down (face up).
