controlair CG330 Installation, Operation And Maintenance Instructions

INTRODUCTION
The Type CG330/CG340 Instrument Air, Compressed Gas Filter Regulator and Regulator are ideal for low emission applications that must comply with
strict fugitive emissions regulations. Maximum allowable inlet pressure is 250 psi (17 BAR). Operating temperatures are 0 to 160ºF. The Type
CG330/CG340 has low capacity internal relief which provides very limited down stream over pressure protection.

INSTALLATION
1. Install the regulator/filter as close as possible to the instrument or tool it is to service.
2. Clean all pipelines to remove dirt and scale prior to installation.
3. Install the regulator/filter so that the direction of flow is from the "IN" to "OUT" connection as marked on the body of the regulator/filter.
4. For best drainage, orient the drain valve so that it is at the lowest point on the drip well housing. Positioning of the drain valve may be
improved by rotating the drip well with respect to the body.
5. The exhaust port should be kept free and unplugged. Rotating the bonnet relative to the body may change the vent hole orientation.
