1. First remove the UV lamp by following steps as outlined in the “Lamp Replacement” section on page 8.
2. Shut off the upstream water supply that feeds water into the reactor chamber.
3. Shut off the downstream water supply. If your system does not have a separate downstream valve, simply open a down-
stream faucet to release any pressure that may be built-up in the system.
4. Unscrew the two aluminum nuts from the reactor chamber. CAUTION: Care
should be taken when unscrewing the bottom aluminum nut, otherwise the
quartz sleeve could fall and break. Place a small pail under the reactor
chamber to catch any water that may leak from the system (if installed
vertically). See picture E.
5. Carefully remove the two o-rings from the aluminum nuts. Grasp the quartz
sleeve and fully remove from the reactor chamber. As with the lamp, make
sure the sleeve is removed from the reactor chamber being careful not to
angle the sleeve as it is removed from the reactor to avoid breakage. See
picture F.
6. Clean the sleeve as outlined in above, or replace with a new sleeve.
Reinstall the quartz sleeve. To install the sleeve, carefully insert the sleeve
into the reactor chamber (do not drop). Install the other side aluminum nut
and o-ring once the sleeve reaches the other end. Make sure to clean and
lubricate (silicone release grease part # 92360) the o-ring. Discard the o-ring and replace it with new one if required.
7. Reinstall the other aluminum nut with o-ring (make sure to clean and lubricate the o-ring, also replace if necessary)
8. Reinstall the lamp as outlined in the “lamp replacement” section on page 8.
9. Slowly turn on the water and pressurize the reactor to verify that there are no leaks.
10. Reconnect to power source.
NOTE: If the system is put on a temporary bypass or if it becomes contaminated after the disinfection system, it will be neces-
sary to shock the system with household bleach for a full 20 minutes before resuming the use of the water.
Control Box Operation
The control box is a dual voltage 115V/230V, 50Hz/60Hz. Make sure
the power cord of the control box is connected to GFCI recep-
tacle.
Lamp Countdown Timer
The lamp countdown timer keeps track
of the number of days of lamp has been
replaced since. The lamp needs to be
replaced after a year (or 365 days) of its operation.
The countdown timer works on a LR44 battery cell which can run
the timer for approximately five years.
When the 365 days have expired, the screen will start to blink and
alarm an audible beep. Replace the UV lamp (see instructions in
“lamp replacement” section) and reset the timer.
Reset the Countdown Timer
Press the reset the button once to
reset the countdown timer to 365 days. The 365 days will appear on the
screen
The countdown timer can also be removed from the holder and
installed in remote location with the help of the magnet location at the
back of the timer.
LED is GREEN when lamp
is working
LED is RED when lamp is
NOT working. The con-
trol box also sounds an
audible alarm during this
condition
