Method of Installation Two methods of installation are recommended for the proper placement of the spray ball within the tank. The “Removable” options is recommended as it allows for removal, inspection, and maintenance of the spray ball. Removable – This consists of a tank inlet adapter that has a clamp cap welded to the tube and which in turn clamps to a tank port. The clamp ferrule at the outer end of the tube connects to the CIP supply line. Generally, the spray ball recommended for this arrangement is one of a smaller diameter than the tank port through which it is installed, unless the spray ball can be installed by reaching into the tank.
Permanent – This consists of a supply tube that is permanently welded through the top of the tank. The tube should be mounted in place with weld collars inside and outside to provide rigidity to the assembly and a proper sanitary radius within the tank. The interior welds need to be ground to a proper finish to match the interior of the tank. Supply Tube Hole Location for Spray Ball Attachment - Sani-Matic static spray balls are typically supplied with a slip connection, allowing the spray ball to be removed for inspection and cleaning. The slip connection is designed to allow flow between the collar and the inlet pipe to assure that area gets cleaned during CIP. Sani-Matic manufactured supply tubes are designed to ensure this flow. The inlet pipe needs to be carefully cut and drilled at the required distance from the end to ensure this solution bypass. the pipe to mark both sides of the hole prior to drilling. After drilling, the hole should be deburred on both the ID and OD. Inlet adapters and supply tubes should be polished ID / OD to the same finish as the vessel they are installed in, or a minimum of 32 Ra to meet sanitary requirements. Also note that the supply tube must have at least (3) 1/16” holes drilled below the cap to clean the tank inlet fitting, and that the inlet tube must be welded to the cap with a 1/8” radius minimum to prevent a sharp inside corner that can trap residue.

Hole Size – Each Sani-Matic spray ball is provided with a pin to attach the spray ball to the supply tube. The diameter of the pin varies according to the diameter of the supply tube. It should be slightly oversized for ease of pin insertion and to allow some solution to bypass to clean the orifice. Align the spray ball on
