Some installations may benefit from remotely exhausting air from the pump to
eliminate unwanted air turbulence or to prevent potentially damaging chemical
vapors from entering the pump air cavities.

Remove existing Muffler Assembly from the back of pump head.

Install Exhaust Plug in Exhaust Port.

Install the appropriately sized (3/8” OD) fitting and tubing (not provided) to
remote exhaust. A remote muffler assembly may be installed at the point of
exhaust if required for condition needing the check muffler (see Section
1.3.b).

at a length of 10 ft. (3 meters) maximum.
