Instructions
- The Culligan D-40A under sink water filter life is up to 6 months or 600 gallons, depending on the quality of your water
- The Culligan D-40A should be installed with the end of the filter with the hole, facing up
- If no water is passing through the system, the filter is likely installed upside down
- If the flow restriction in the Culligan D-40A is too great, you can increase the flow rate by drilling a larger hole, where the existing hole is, with a 1/8-inch drill bit
