the installer MUST check for leaks at all connections
made during installation.
Power On
Turn on the 110-120 VAC power to the Manifold.
Make sure the circuit breaker is switched to on near
the power supply.
The Powerex FirstCall™ Manifold is pre-programmed
for the appropriate gas and standard NFPA 99 pressure
settings from the factory. However, some settings are
able to be adjusted from the touchscreen HMI control
panel.

Pigtail & Cylinder Installation
The check valve outlet fittings on the manifold header
bars are CGA gas-specific threads. Each of these fittings
has an integral check valve. Make sure the 3-digit CGA
number stamped on the outer perimeter of these
fittings matches the CGA number stamped on the
mating CGA fittings on the pigtails. Attach the pigtails to
the check valve outlet fittings on the manifold header
bars.
Liquid x Liquid
Connect the other end of the pigtail to the “Use” valve
mating fitting on the portable bulk vessel. Open the use
valve (turn counter-clockwise to open). The pressure
building valve or regulator should be turned on or
opened for all vessels connected to the manifold (both
service and reserve banks). Allow approximately 1 hour
for the portable bulk vessel(s) to build pressure.
Cylinder x Cylinder
Connect the pigtails to the check valve outlets on the
manifold headers
Check the master valves to be certain they are open
(turn counter-clockwise to open). (Note: the master
valve should always be left open. It is to be used only in
the event of an emergency).
Check all cylinder and pigtail connections for leaks
using an oxygen safe leak test solution (any bubbles
forming around connections indicate leakage). The
manifold has been tested for leaks at the factory, but
