Step 11:  Replace the o-ring and slide the sleeve back into the reactor following steps 7 and 8 

from the installation section of the manual.

Cleaning the UV Sensor

Depending on the water quality, the UV sensor may require periodic cleaning. At a minimum, 

the UV sensor should be cleaning on an annual basis. The following steps outline a basic clean-

ing procedure.

Step 1:  If a by-pass assembly is installed, shut the inlet valve off to prevent water flow through 

the system. Otherwise, turn off main water inlet valve (and/or turn off the water pump).

Step 2:  Disconnect power cord of UV system from electrical outlet.

Step 3:  Release water pressure by opening a downstream faucet and then close the outlet 

shut-off valve (if any). If there is no outlet shut-off valve, expect water to drain from the system 

as the head pressure in the system will cause the water to flow back down.

Step 4:  Place something under the reactor to catch any water that may come out of the reac-

tor during the removal of the UV sensor.

Step 5:  Unscrew (counterclockwise) sensor nut from the reactor and pull the sensor slowly out 

of the sensor port.

Step 6:  Holding the sensor in your hand wipe the flat portion (sensor face) of the sensor with 

isopropyl alcohol using a clean lint-free cloth.

Step 7:  Replace sensor following step 9 from the installation section of the manual.

Operation

RMS systems come with a feature laden controller that incorporates both the lamp driver (bal-

last) and control features in one water-tight case. Four main controllers are available for the RMS 

systems (depending on your model). All four models feature a power factor corrected, constant 

current lamp driver with a universal power input. 

Please Note: While the LED or display screen is red and the buzzer is sounding the water from 

the system should NOT be consumed. If any water does pass through the system during this 

period, please follow the disinfection procedure as outlined in this manual before the water is 

consumed. For RMS4 & RMS5 systems, even though they have a visual and audible warning built 

into the controller, a green LED or status screen does not necessarily indicate that the water 

coming from this system is in fact potable (safe to drink). These systems do not measure the level 

of disinfection; they simply measure the “on-off” status of the lamp. Please have your water 

checked for microbiological contaminants on a regular basis.
