Installation Instructions
1. The pressure switch should be installed with reasonable
accessibility for service. Pipe joint compound should be
applied sparingly, and only to the male threads, never to the
female threads. Do not use PTFE
tape to seal joints - pieces
have a tendency to break off and lodge inside the unit,
possibly causing malfunction.
2. Install pressure switch in gauge ports, manifold blocks, or
any airline application. Mounting may be in any position.
3. Installing a filter upstream of the pressure switch will provide
added protection against rust, pipe scale, and other foreign
matter.
