System Maintenance

Filters:

Filters need changed regularly to ensure
protection of the membrane and high
purity water production.
The replacement filter set you need
depends on the optional filters you have.
You can use the chart as a guide, or call
us with the name it was ordered under
and we can assist you. All of the listed
items, as well as individual & specialty
filters, may be ordered securely online

. With average

usage and normal water conditions filters should be changed every 6 months. The more water you use
or the dirtier your water the more often you will want to change filters. If the first filter (sediment filter)
gets dirty quickly it may need changed more often than the rest, part number for the individual sediment
filter is SED105. All filters (excluding the membrane) should be changed at least every 12 months. The
UV bulb can be checked to determine if it is still on by looking at the end with the wire coming out, it
should glow purple. If it is not then the bulb has burnt out. Average life on the bulb is 12-18 months,
though it is recommended to change it every 12 months to ensure effective filtration, as the bulb
intensity diminishes over time. To change, simply pull on the wire and the bulb will slide out.

How to change filters:
Note

: The tank will need to be emptied when changing filters. If you would like to save the water in the

tank for use, follow the instructions below, opening the faucet and collecting the water from the tank
after turning the feed water off.

Turn off the feed water supply. This is done by closing either the angle ball valve or the feed water
ball valve. The valve is closed when the handle is at a 90° angle to the tubing (when handle is NOT
parallel to tubing). If saving water from the tank, do so after closing the valve.

Shut the ball valve on the tank. The valve is closed when the handle is at a 90° angle to the tubing
(when the handle is NOT parallel to the tubing).

Open the faucet to release any remaining pressure.

Pull the system out to where it can be easily worked with. If the system was installed with enough
tubing to do so, simply pull it out to where it can be worked on. If the system does not have enough
tubing, you will need to disconnect the lines to pull it out. (When changing filters, it helps to have a
towel handy, as some water may leak out.) Make note of which tube goes where to ensure the
system will be hooked up the same way it was.

Remove the first filter housing. To remove, use the filter housing wrench supplied with your system.
When looking down at the top of the system, the filter housing will turn clockwise to loosen,
counterclockwise to tighten. Once the filter housing has been removed, pull the filter out and replace
with the new one. At the top of each housing is an O-ring, when changing filters it is recommended to
remove the O-ring and check for any damage such as nicks, gouges, or kinks. If damage is found,
replace before continuing, otherwise, use a silicon based lubricant (vegetable oil can be used if no
silicone lubricant is available) and lubricate the O-ring, place it in the filter housing and screw the
housing back in place. This will help prevent leaks.

Repeat step 5 with each housing, replacing the old filter with the similar new filter and checking the
O-rings. If any of the filters have only one gasket (the middle filter on most systems will have only one
gasket) the filter will need to be installed with the gasket at the top of the housing, unless dictated
otherwise by the filter itself.
