Installation & Maintenance Tips

n

n
• Install vertically with cap up and sufficient clearance above for cartridge removal.

n

• Use a bracket or sturdy shelf to support the housing weight when full.

n

• Before inserting a new cartridge, lubricate the O-ring lightly and ensure it seats correctly to avoid leaks.

n

• To change cartridges, push the pressure-relief button (if fitted) before unscrewing the cap.

n

• Replace cartridges at the recommended intervals (sediment every 6-12 months, carbon blocks as needed) and switch to a new housing if you notice any cracks or clouding in the clear body.

n

• After servicing, check for leaks and ensure expected flow is maintained. Clear housings can help you see early signs of bypass or O-ring failure.
