- Page 2 INSTRUCTIONS FOR USE Safety Precautions and Good Practice It is essential that distributors ensure users of the Point Four diffusers are informed both verbally and in writing about the safe and correct use of diffusers. WARNING: THE DIFFUSER MUST ONLY BE OPERATED WHEN SUBMERGED. When the diffuser is under pressure substantial potential energy is stored in it.

Page 3: Installation
INSTALLATION To avoid bubble coalescence, place the diffuser horizontally and do not obstruct the surface with protective screens. The deeper the diffuser is placed in the water the more effective it will be. Secure diffuser to a flat surface using "Velcro" strips, silicone or screws. - Page 4 Recommended (and not recommended) pressure regulator-flowmeter combinations used to supply oxygen to microbubble diffusers...

Page 5: Maintenance And Care
MAINTENANCE AND CARE The only maintenance required is periodic cleaning to maintain an even bubble pattern over the full surface of the diffuser. Diffuser fouling or plugging manifests itself by a noticeable decrease in flow at the original flowmeter and pressure regulator settings. Pall-off in flow due to gradual plugging can be compensated for by increasing the supply pressure Do not increase the line pressure beyond 50 psi (3.5 bar) to offset the decrease in gas flow because of plugging. - Page 6 REPAIRING DIFFUSERS Cracks and Fractures: Occasions do arise when the diffusers’ ceramic cracks or fractures due to physical abuse or over pressurization. In many cases the diffusers can be repaired. We recommend that the diffusers are returned to Point Four for repair. There are cases where it might be advantageous to repair at the customer’s or distributor’s site.

Procedure to remove a cracked fitting: 1.
