16. Connect the power cable (4043) to the ballast and then to the AC
supply (with surge protector). The green lamp-on LED will light up
followed by three buzzer beeps and three red timer LED flashes. Your
Rainfresh UV Disinfection System is now ready for service.
(E) DISINFECTION PROCEDURE
Before service begins, all household plumbing lines should be disinfected to prevent the possibility of re-contamination
after UV disinfection. You should also disinfect your plumbing system if the power goes out for several hours or more or if
the unit has been accidentally shut-off for several hours or more. It is advisable to disinfect the plumbing lines at least
once a year.
The following is a general method for disinfection of plumbing lines. If you are uncertain about the efficacy of this
procedure you are advised to contact your local health authority responsible for water safety.
1. Shut off the supply valve and de-pressurize the lines by opening a tap until it runs dry.
2. Remove the filter in the filter housing and add about 1-2 cups (250-500ml) of unscented household bleach (5 to
6% sodium hypochlorite) to the empty filter housing and put it back on the filter head.
3. Open the supply valve and slowly open a faucet and let the water run until you can smell the chlorine and then
shut the faucet off. Repeat the procedure for all hot and cold outlets in the house. Add more bleach as required.
Run hot faucets longer to allow the chlorine to come through the hot water tank.
4. Leave the bleach solution in the plumbing system for about 6 to 8 hours preferably overnight.
5. Shut-off the supply valve again and open a faucet to depressurize the system. Open the filter housing and re-
install the filter cartridge and then re-attach the filter housing. Make sure that the UV system is ON.
6. Take off aerators (if any) on the faucets and thoroughly flush all outlets until the chlorine smell is minimal.
7. Open the supply valve slowly. You are ready to use the water now.
(F) UV BALLAST FEATURES
The micro-processor controlled electronic UV ballast
supplied with your Rainfresh UV system has both audio
and visual alarm indicators to indicate the lamp
operation and an integral annual lamp change reminder
timer.
UV Power Source Initialization Sequence: When AC power is applied to the UV ballast, the lamp is ignited as indicated by
the green lamp-ON LED and alarm buzzer consisting of three buzzer beeps and three red timer LED flashes.
Normal Operation: During normal operation only the green lamp-ON LED is illuminated.
Lamp-Change Timer Operation: At the end of 11 months (one month before end of lamp life), the red lamp-change timer
LED will flash and the buzzer will sound indicating that the timer is in a 28-day grace period. You can silence the buzzer
for seven days by pushing the timer button, but the LED will continue to flash. At the end of the 28-day period, the red
timer LED illuminates continuously and the buzzer sounds. Pressing the timer button at this point will not silence the
buzzer until the lamp is replaced. The UV lamp is not shut down in this alarm mode.
