controlair 330 Installation, Operation And Maintenance Instructions

INTRODUCTION
The Type-330/335/340/345 Instrument Air Filter Regulators, Air Regulator & Filter Series are designed for air or gas service. Maximum allowable inlet
pressure is 250 psi (17 BAR). Operating temperatures are 0 to 160ºF (-62
capacity internal relief which provides very limited down stream over pressure protection. Note: Non-relieving version does not provide internal relief.
To avoid exceeding outlet pressure limits in service, a pressure-relieving or pressure-limiting device should be provided.

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.
