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.
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 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 minumum 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 UV Disinfection 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 ground screw from the ground 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.
Step 9
: Using a soft, lint-free cloth or towel wipe the sleeve down using a commercial
scale cleaner (i.e. CLR
®
or LIME-A-WAY
®
). This removes scaling or iron deposits that
may be on the outside of the quartz sleeve. Be careful not to get any moisture or liquids
inside of the sleeve.
