Test Shutoff Valve Monthly
The Optional Solenoid Shutoff valve should be tested monthly to confirm it opens
and closes. Unplug valve from unit to confirm water stops flowing. Plug the valve
in again to confirm water continues to flow.
Clean Air Filter Periodically
The Upstream contains a washable air filter in the blower housing panel (See
Figure 1H). Periodically check and clean the filter to ensure blower operation is
not impeded.
Replacing and Cleaning UV Lamps
The Upstream contains two ultraviolet (UV) lamps that emit high-intensity UV
light in the germicidal range, providing effective disinfection of the water flowing
through the unit. The lamps in your unit will decay over time and should be
replaced every 12 months for optimum performance. Avoid continuously starting
and stopping the unit within a 24 hr period, as this will accelerate the aging of the
UV lamps (note: however shutting down the system for seasonal use will extend
lamp life)
Your unit has an internal timer to keep track of the lifetime of the lamps. It will
issue a warning when the end of their lifetime approaches (see Troubleshooting
Guide). The amount of life remaining on the lamps is measured in hours and can
be seen in the main section of the menu.
The lamps can be replaced in a few minutes. Draining the unit is not required.
See Figure 3.
Caution:
The lamps in the unit emit ultraviolet (UV) light that can cause
permanent damage to the skin and eyes.
Never look at a lamp when it is
operating. Always unplug the unit before replacing lamps.
Caution:
Never touch the bulb (quartz portion) of a lamp with your fingers.
Handle the lamp by its ends only. If the surface of the lamp becomes dusty or
dirty, use a clean lint-free cloth and some rubbing alcohol to remove the dirt. For
more difficult stains such as water spots, use a scale remover to remove the
stain and then rubbing alcohol afterwards. The lamps are fragile and must be
handled with care.
