- Drill with 1/4-inch and 1/2-inch drill bits (if drilling a new faucet hole)
- Utility knife or tube cutter
- Bucket and towel
- 테프론 테이프
2.2 수도꼭지 설치
- If your sink has a pre-drilled hole (e.g., for a soap dispenser), remove any existing fixture. If not, drill a 1/2-inch hole in a suitable location on your sink or countertop.
- Assemble the dedicated faucet by screwing the spout onto the faucet body.
- Place the rubber gasket onto the threaded faucet stem.
- Insert the faucet stem through the hole in the sink/countertop.
- From underneath the sink, slide the metal washer and then the plastic stem nut onto the faucet stem. Hand-tighten the nut to secure the faucet.
2.3 물 공급 연결
- Turn off the cold water supply to your main kitchen faucet.
- Disconnect the cold water line from the 1/2-inch threaded stub on the bottom of the cold water faucet inlet.
- Apply Teflon tape to the male threads of the faucet stop and the supply adapter.
- Screw the water supply adapter onto the threaded faucet stub.
- Reconnect the cold water line to the male supply adapter threads. Hand-tighten and then snug with a wrench.
2.4 Filter Head Mounting
- Choose a location under the sink to mount the filter head. Ensure there is at least 1.5 inches of clearance below the filter cartridge for future changes. The filter head should be mounted vertically on a firm surface.
- 장착 브래킷을 본떠서 나사 위치를 표시하십시오.
- Drill pilot holes using a drill bit slightly smaller than the supplied screws.
- Mount the filter head using the supplied screws.
2.5 배관 연결

- Insert one end of the tubing into the supply adapter until it is fully seated.
- Insert the other end of the tubing into the filter inlet until it is fully seated.
- Measure and cut the plastic tubing to connect the filter outlet to the dedicated faucet.
- Slide the compression nut and ferrule over one end of this tubing, then insert the plastic insert into the end of the tubing.
- Push this end of the tubing firmly into the dedicated faucet stem. Hand-tighten the compression nut onto the threads until secure, then tighten approximately half a turn with a wrench.
