warranty on the system. We are not responsible for any damaged

caused by using Vaseline or other petroleum lubricants. To ensure

a good seal and minimize any possibility of leaks, it is

recommended you replace your O-rings periodically, usually every

1-2 years.

Housings

With the regular stress of removal and tightening, filter housings

will weaken over time. To help prevent unwanted system failure

the filter housings on your system need to be replaced every 5

years.

UV Filter:

The UV filter uses a bulb to kill bacteria. When the filter is plugged

in and operating, the white cap where the wire comes out will

glow a purplish color. If you ever notice that the filter is not

glowing it means the UV bulb is no longer working. IMMEDIATELY

STOP using the system, as bacteria may be contaminating your

water. Replace the bulb and sanitize the system to ensure safe,

treated drinking water. The bulb does wear out and needs to be

replaced; recommended replacement is every 12 months. It is

important to note that the bulb may glow for longer, but the

intensity of the bulb diminishes over time and after 12 months

full, effective treatment is not assured.

Buildup on the quartz sleeve can also decrease the amount of

effective light that treats the water, so regular checking and

cleaning of the sleeve is recommended.

To change the lamp:

The lamp is enclosed inside a quartz sleeve, so the water does

NOT need to be shut off to change the lamp. Unplug the white

wire from the transformer and grasp it near the white cap on the

end of the filter. Ensure you have a firm grip on both the filter and

the wire, and pull on the wire. The white cap will pull out with the

lamp. Then, simply push the new lamp in place.

To clean/replace the quartz sleeve:

1. Turn off the feed water supply. This is done by closing the angle

adapter 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.

2. Shut the ball valve on the tank. The valve is closed when the

fitting and tighten until snug, making sure to not over-tighten,

which would cause the filter to crack or could strip out the

threads.

3. Now we will install the filter(s) in the order shown by the

diagram on the back of this sheet. Start by installing the UV filter

(if applicable). First, cut the line between the auto shutoff valve

(ASV) and the membrane housing, making sure that you leave

enough tubing coming from the ASV to reach the UV filter. Next,

place a stem elbow on the end of the piece of tubing. Then run a

piece of tubing from the membrane housing cap to the opposite

side of the UV filter. Place a stem elbow on the end of this tubing

that connects to the UV filter also. Connect the other end of the

tubing to the membrane housing. Place the relevant clips onto the

membrane housing, push the UV filter into the clips, and insert

the stem elbows into the UV filter.

4. Next, disconnect the tee fitting from the carbon post filter that

is currently installed on the RO system and remove the filter.

Place the relevant clips onto the membrane housing, then push

the first filter into the clips, making sure the water flow is going

the same direction as the carbon filter was going. Insert the tee

fitting into the input side of this first filter.

5. Follow the same process for each filter, making sure that the

flow coming out of the previous filter enters the input side of the

next filter, following the direction of flow indicated on the filter.

Faucet Installation

Locate the installation point for the faucet; you will need a hole at

least 1/2" in diameter for the RO faucet shank. If the sink has a

sprayer the RO faucet may be installed in the hole used for the

sprayer, simply disconnect the sprayer and plug the sprayer

connection. If the sprayer hole is not an option you will need to

drill a hole. To drill a hole, determine where it will be located

before starting. You will need a 2" flat surface no more than 2"

thick. Ensure the chosen location will not interfere with anything

below, and position the faucet so it will empty into the sink and

can swivel freely for convenience. Once you have confirmed your

faucet location, proceed with drilling the hole in your sink.

Drilling a hole for the faucet

Be careful when drilling the faucet hole. Be sure to drill slowly to

prevent chipping or scratching, and be sure to wear proper safety
