System Disinfection
With a new installation, or any time the UV system is shut down for service, without
power, or is inoperative for any other reason, the lines in the home or facility could be
contaminated. Use the following steps to fully disinfect the lines throughout the entire
home or facility.
For Rainwater tanks, add Acquasafe to your tank water supply and mainatin the
required result on test strips for the first month at least. This will clean your pipe lines
downstream without water wastage. Acquasafe can be used at the same time as UV
and is another protection against pathogens.
For other water sources or where the plumbing maybe suspected of having
contamination the use of stronger chemical flushing maybe needed.
Step 1:
Check for and remove any “dead ends” in the lines throughout the home as
these can harbour bacteria. Plug in the UV system and wait until it is ready for
operation.
Step 2:
Remove the filter cartridge from the last sump and fill it with the applicable
volume of plumbing sanitiser or 1-2 cups of household bleach (most are 5.25%
chlorine). Replace the sump and slowly turn on the water supply.
Step 3:
At a water outlet, run the water until bleach can be smelled. Repeat this for
all faucets, toilets, shower heads, refrigerators, outdoor taps, the washing
machine, dishwasher, etc. at the home or facility. Once finished, wait a
minimum of 30 minutes before continuing.
Step 4:
Reinstall the filter cartridge into the sump and flush the chlorine solution by
opening all faucets until chlorine can no longer be detected. Your home has
now been completely disinfected with your Microlene Aquashield Centurion
UV system ready to inactivate any microorganisms that enter the home.
Cleaning the Quartz Sleeve
Depending on the water quality, the quartz sleeve may require periodic cleaning. At
a minimum, the quartz sleeve should be cleaned on an annual basis. The following
steps outline a basic cleaning 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:
Remove the captive earth screw from the earth lug on the UV chamber.
Step 5:
Remove the lamp connector from the chamber (gland nut) by pushing the
Lamp connector in and turning it ¼ turn counter-clockwise. Disconnect the
lamp connector from the lamp. CAUTION: the lamp may be hot!
Step 6:
Being careful to touch only the ceramic ends, remove the lamp out of the
chamber.
Step 7:
Unscrew the gland nut from the chamber exposing the end of the quartz sleeve.
Step 8:
Remove the quartz sleeve and o-ring by
gently twisting and pulling
the
quartz sleeve.
