RCM–2 AIR DISTRIBUTION MANIFOLD
Part Number 18159

Description
The RCM–1 and RCM–2 Air Distribution Manifolds answer the need for high quality low cost manifolds. Using quality
valves and a machined polyacetal manifold ensures pressure tight integrity, ruggedness and a long dependable life. The unique
vertical mounting scheme conserves scarce shelter wall space without sacrificing convenient access.
The only difference between the RCM–1 and RCM–2 is the full-scale pressure gauge calibrations. These are 15 oz/in2
(gauge) and 15 psig repectively.
An RCM–1 or RCM–2 Air Distribution Manifold provides nine ports. Each port provides a cut off valve with 1/8" NPT female
fitting. These manifolds can be used to connect an ADH or EDH series dehydrator to as many as 8 antenna transmission lines or
other pressure system devices. Alternatively, multiple dehydrators can be connected to a pressure system to add the additional
protection offered by redundant dehydrators.
Individual valves combined with the pressure gauge permit quick identification of a leaking antenna or dehydrator.
Isolation of the leaky system permits normal operation of the remaining antennas.
For complete information describing its application, installation and features, please contact Customer Service or check on
the web at www.networketi.com.
Unpacking
Inspect the shipping container and packing material for damage. Save the shipping container and related materials until
normal operation has been established. If the unit must be returned, take care to ensure that it is packed as it was received.
