There are three main components to the "Trifecta" system:
• Medium Pressure Bulk Tank (Minimum 175 psig)
• Vaporizer(s)
• Trifecta Pro Series Skid
The Trifecta Pro Series has been designed for ease of
installation and operation. An ideal install has the Trifecta

Safety Product Manual - Trifecta®Pro Series
Caution! Before locating oxygen
equipment, become familiar
with the relevant National Fire
Protection Association (NFPA)
standards for “Bulk Oxygen
Systems at Customer Sites,”
and with all local safety codes.
The NFPA standard (www.nfpa.org) covers general
principles recommended for installing bulk oxygen systems
on industrial and institutional consumer premises.
Caution! To prevent possible tip over, do
not leave tank standing upright
unless it is secured to its
foundation (bolted down).
Transporting and erection of the tank should be performed in
accordance with rigging instructions available from Chart.
Failure to comply with these instructions may result in
serious damage to the container.

Warning! If clothing should be splashed
with liquid oxygen it will become
highly ammable and easily
ignited while concentrated
oxygen remains. Such clothing
must be aired out immediately,
removing the clothing if
possible, and should not be
considered safe for at least 30
minutes.
Nitrogen and Argon
Nitrogen and argon (inert gases) are simple asphyxiates.
Neither gas will support or sustain life and can produce
immediate hazardous conditions through the displacement
of oxygen. Under high pressure these gases may produce

entering areas where the oxygen content is below 19%
unless equipped with a self-contained breathing apparatus.
Unconsciousness and death may occur with virtually no
warning if the oxygen concentration is below approximately
8%. Contact with cold nitrogen or argon gas or liquid can
cause cryogenic (extreme low temperature) burns and freeze

The backside (PB Side) of the Pro Series skid has two/three
connection points.
• Connection (A) serves as both the high pressure gas
outlet and the liquid inlet when the tubing connection
between A and B is in place
• Connection (B) is the high pressure gas outlet when the
tubing connector between A and B has been removed.
• Connection (C) is the high pressure liquid outlet to the

It is important that care is taken to install the Trifecta Pro
Series system on a dedicated electrical power circuit that is
clean and protected. Circuits that are susceptible to noise and
brownouts may cause erratic system behavior. Care should
also be taken to avoid installation on a circuit that regularly

Warning! It is important to purge the
entire Trifecta Pro Series and
piping with warm, dry nitrogen
before running the system with
liquid. Water vapor can cause
ice crystals to form that may
cause the solenoid valves and
other critical components to
operate improperly.

Purge and Pre-Charge of the Trifecta Pro
Series (Ref. to Fig. 4, Pg. 23 for valve tags)
Verify that the controller is in the manual mode (see details
below) and all valves are closed.
Before beginning purging, in
the top right hand of the screen
should say “Manual.” If it says
“Automatic,” you will need to
change it to manual
First, you will touch the Menu
button on the screen. This will
bring up a pop up box.
Then press the “Manual” button,
which should be blue when it is
in manual mode.
Note: The manual control screen
can be used to manually
open/close all the solenoid
valves. This will be
required for initially
purging the Trifecta and
for troubleshooting.
Then touch the “Manual” button
on the screen.
