Correct setup of your bigboi D-IonizR is essential to prevent leaks, avoid blow-by, and ensure accurate Total Dissolved Solids (TDS) readings. This guide walks you through how to properly use the included filter guides during setup for both the 2-Stage and 3-Stage units.

Step-by-Step Installation Instructions

1. Check O-Rings

• Open each tank and inspect the top edge.

• Ensure the black rubber O-rings are present and seated securely in their grooves.

• Damaged or missing O-rings can lead to water bypassing the filters and leaking from the system.

2. Lubricate the O-Rings

• Apply a light, food-grade silicone lubricant to the O-rings.

• This creates a tighter seal and prevents pinching or warping when the tanks are tightened.

3. Insert Filters and Filter Guides

• Place one resin filter cartridge into each tank.

• On top of each filter, insert the plastic filter guide locator.

• These guides centre the filter inside the tank, helping to eliminate side-flow (blow-by) that reduces efficiency and increases TDS levels.

4. Secure the Tanks

• Screw each tank back onto the top manifold (head) firmly by hand.

• Make sure each tank is tightened evenly to avoid unbalanced pressure or leaks.

5. Check for Leaks

• Once connected to the water supply, run water through the unit and inspect for leaks.

• If leaking occurs, re-check the O-rings, filter guide alignment, and tank tightness.

Why the Filter Guides Matter

Using the filter guides properly ensures:

• Maximum filtration performance

• Lower TDS output

• Reduced risk of internal leaks or water bypass

• Increased lifespan of the resin filters
