Step 2: Remove the cartridge from the filter housing and fill with 1-‐2 cups of household bleach (most household
bleaches are 5.25% chlorine). Replace filter housing and slowly turn on the water supply.
Step 3: Go to each location in the home or facility (including outdoor taps) and run some water until chlorine can
be detected (by smell). Ensure all taps, dishwashers, shower heads, washing machines, toilets, showers,
refrigerators, etc. are all checked. Once the chlorine is detected at each location close all taps and let the chlorine
sit in the lines for a minimum of 30 minutes.
Step 4: After 30 minutes, reinstall the filter cartridge into the filter housing and then flush the chlorine solution by
opening all taps and let them run until chlorine can no longer be detected (by smell). Your home has now been
completely disinfected with your CALMAG YORKSHIRE LIMITED UV system ready to inactivate any microorganisms
that enter the home.
PLEASE NOTE: This procedure must be performed following any time the UV is shut down for service, without
power, or is inoperative for any reason in order to avoid possible contamination of the water lines.
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 the system has an inlet shut-‐off valve, shut this valve off to prevent water flow through the system. If
there is no inlet shut-‐off valve, turn off main water inlet valve (and turn of water pump if you have one).
Step 2: Disconnect power cord of the UV system from the electrical outlet.
Step 3: Release the water pressure by opening a downstream tap and close the outlet shut-‐off valve if the
installation incudes one (if there is no outlet shut-‐off valve, be prepared for water leakage from the system as the
head pressure in the system will cause water to flow back through the outlet plumbing and through the unit).
Step 4: Remove the captive ground screw from the ground lug on the UV unit.
Step 5: Remove the lamp connector from the unit (gland nut) by pushing the connector in and turning it ¼ turn
counter-‐clockwise (gently pull on the lamp cable to ensure the connector is seated properly).
Step 6: Pull lamp out of unit still attached to connector.
Step 7: Remove the gland nut from the unit exposing the end of the quartz sleeve.
Step 8: Carefully pull the quartz sleeve out of the unit and remove the O-‐ring.
Step 9: Using a soft, lint-‐free cloth or towel wipe the sleeve down using a good commercial scale cleaner to
remove any scaling or iron deposits that may be on the outside of the quartz sleeve. Be careful not to get any
moisture or liquids on the inside of the sleeve.
Step 10: Wipe the sleeve with separate dry cloth.
Step 11: Once the sleeve is cleaned replace the O-‐ring and slide the sleeve back into the unit following the steps
outlined on page 8 of the manual. Be careful not to damage/crack the sleeve on insertion.
