BAPL-1397 has a description of ST-261-I UNLOADER W/INJECTOR 2.4mm

• Downstream injection at 10:1 ratio
• Low pressure limit setting eliminates need of additional metering devices
• Relies on pressure loss through a restrictive orifice, which is built-in on the ST-261. Restriction AFTER the orifice must be minimized in order for injection to occur. Therefore, this system must incorporate a large orifice spray nozzle which reduces such restriction. The usage of a nozzle with a minimum orifice size of 30.0 is recommended. A smaller nozzle could be used, but the added restriction may result in ineffective suction rates or no suction at all. In addition, remember that elbows, fittings, and even hose add to the restriction within the system and may affect or eliminate the suction capabilities
