Installation & Maintenance Tips

• Install vertically, with the cap at the top and sufficient clearance for cartridge changes.
• Use a sturdy wall-mount bracket capable of supporting the full housing weight when filled.
• Before inserting a new cartridge, lightly lubricate the O-ring with food-grade silicone grease to extend seal life.
• Use the included or compatible pressure-relief button (if fitted) to safely release housing pressure before opening.
• Replace cartridges according to your water quality and system use (e.g., sediment every 6–12 months, carbon blocks as required). Inspect the housing body and brass connections regularly for signs of wear or leaks.
• After servicing, ensure all connections are tight and check for leaks under standard pressure.
