Installation Guide

Removing the existing filter:

• Turn off the water supply to the filter under the sink.
• Turn on the tap to empty water from the line.
• Hold the collet and gently pull the tube out.

Installing the new filter:

• Follow the arrow on the filter — Inlet to Outlet.
• Push the tube into the collet as far as it will go at each end.
• Gently pull the tube to confirm it has locked into place.
• Turn the water on and flush for a few minutes to clear carbon fines.

What Are VOCs?

Volatile Organic Compounds (VOCs) are chemicals that can enter drinking water from industrial, agricultural, or household sources. Common examples include formaldehyde, benzene, toluene, ethylene glycol, and xylene. The K5520 is effective at reducing these contaminants.

What Are Cysts?

Giardia and Cryptosporidium are microscopic parasites commonly found in untreated surface water and tank supplies. Cryptosporidium is highly resistant to chlorine — making a 1-micron filter like the K5520 an essential safeguard for rural NZ households.
