Warranty: All Tri-Tech Medical manifolds are warranted against defects in materials and workmanship for
the period of five years from date of purchase.
Introduction
Tri-Tech Medical manifolds are cleaned, tested
and prepared for the indicated gas service and
are built in accordance with the Compressed
Gas Association guidelines. The manifold
consists of a regulator and a header, to provide
an increased supply of gas for the specific
application. Pressure gauges show system
status and alert the need to replace depleted
cylinders. Features of the manifold systems
include a regulator, flexible pigtails (copper
pigtails supplied with oxygen system –per
NFPA 99) with check valves and mounting
hardware.
Caution!
Failure to follow the following instructions can result in personal injury or property damage:
Never permit oil, grease, or other combustible materials to come in contact with cylinders,
manifold, and connections. Oil and grease may react with explosive force when ignited while in
contact with some gases –particularly Oxygen and Nitrous Oxide.
Cylinders, header and master valves should always be opened very S-L-O-W-L-Y. Heat of
recompression may ignite combustible materials creating an explosive force.
Pigtails should never be kinked, twisted or bent into a radius smaller then 3 inches. Mistreatment
may cause the pigtail to burst.
Do not apply heat. Oil and grease may react with explosive force when ignited while in contact
with some gases –particularly Oxygen and Nitrous Oxide.
Cylinders should always be secured with racks, chains, or straps. Unrestrained cylinders may fall
over and damage or break off the cylinder valve which may propel the cylinder from its current
position with great force.
Oxygen manifolds and cylinders should be grounded. Static discharges and lighting may ignite
materials in an oxygen atmosphere, creating an explosive force.
Welding should not be performed near Nitrous Oxide piping. Excessive heat may cause the gas to
dissociate, creating an explosive force.

General Instructions
Manifolds should be installed in accordance with guidelines stated by the National Fire Protection Association,
the Compressed Gas Association, OSHA, Canadian Standards Association, and all applicable local codes. The
Carbon Dioxide and Nitrous Oxide manifolds should not be placed in a location where the temperature will
exceed 120°F (49°C) or fall below 20° F (-7°C). The manifolds for all other gases should not be placed in a
location where the temperature will exceed 120°F (49°C) or fall below -20°F (-29°C). A manifold placed in an
open location should be protected against weather conditions. During winter, protect the manifold from ice and
snow. In summer, shade the manifold and cylinders from continuous exposure to direct rays of the sun.
Leave all protective covers in place until their removal is required for installation. This precaution will keep
moisture and debris from the piping interior, avoiding operational problems.

CAUTION:
Remove all protective caps prior to assembly. The protective cap may ignite due to heat of
recompression in an oxygen system.

MANIFOLD OPERATION
The TSD series manifolds are designed to operate in two ways; to provide an increased supply of gas as well as higher flow
rates than can be achieved using a single cylinder, or to provide a manual changeover to a reserve cylinder.
1. Install the two pigtails provided to the TSD manifold. Connect the two cylinders intended to be used.
Following the cylinder replacement guidelines on page 5.
2. S-L-O-W-L-Y open both cylinder valves (turn counter-clockwise to open). The high pressure gauge will show the
pressure of the cylinder having the highest pressure. (Figure 5)
3. Check the system connections for leaks using an oxygen compatible leak test solution. Correct any leaks
immediately.
4. Adjust the delivery pressure of the regulator to the desired pressure. The selection of the regulator set pressure may
vary due to application requirements. If a pressure setting less than 20 psig is required then a line regulator must
be installed at the manifold outlet.
5. Simulate a depleted bank by closing the cylinder valves and creating a flow of gas through the manifold. The
pressure reading on the gauges will drop.
6. S-L-O-W-L-Y open one of the cylinder valves (turn counter-clockwise to open). Note: this manifold is designed
so that one side is in service (cylinder valve open) while the second side is held in reserve (cylinder valve closed).
7. The manifold is now ready to supply your system.
Pressure Gauge
Regulator High Pressure Gauge
FIGURE 5
The manifold control includes the following components and features; regulator, flexible stainless steel braided pigtails
(or copper pigtails with oxygen systems) with check valve outlets. The manifold is designed to use a line regulator
(optional item) which can be mounted on the manifold outlet for delivery pressure less than 20 psig.
Gas flows through the manifold to the primary regulator and then through the line regulator (if installed). Final delivery
pressure is controlled by the either the line regulator or by the primary regulator should the application not require a line
regulator. (A line regulator is not provided with the manifold.)
As cylinders deplete the high pressure gauge on the regulator along with any alarm systems installed will indicate that the
bank of cylinders should be changed.
After replacing empty cylinder, the manifold is immediately ready for service.

To insure proper operation, observe the following guidelines:
1. Carefully follow all instructions.
2. Be sure cylinder valve is fully opened.
3. Replace empty cylinder as soon as practical after the manifold has depleted, and the full reserve cylinder valve
has been opened, placing it in service.
CYLINDER REPLACEMENT AND HANDLING
1. Shut off cylinder valve on depleted cylinder.
2. S-L-O-W-L-Y loosen and remove the pigtail connection from the depleted cylinder.
3. Remove the depleted cylinder and replace the protective caps.
4. Remove the protective cylinder cap from the full replacement cylinder. With the valve outlet pointed away from
you or anyone else, slowly open each cylinder valve slightly, blow out any dirt or contaminants which may have
became lodged into the cylinder valve.
5. Place and secure full cylinders into position using chains, belts, or cylinder stands.
6. Connect pigtails to cylinder valves and tighten with wrench.
7. Open the header valve. S-L-O-W-L-Y turn the cylinder valve until each cylinder is fully on.
8. The manifold supply bank is now replenished and may be put in service by following the instructions on page 4.

Troubleshooting
Symptom
Remedy
Pigtails won’t connect to cylinders or TSD manifold tee
Check CGA numbers on the cylinder valve or the TSD
manifold tee and the pigtail fittings. The numbers must
match –this ensures there will not be an improper gas
connected to the system. Contact you supplier for assistance.
Leaks
Fittings may need to be tightened or the fittings may need to
be replaced if the seating surface is scratched or scared.
In the case of CO2 pigtails there is a seal washer that is
required at each connection. If the seal washer is missing, it
will leak.
If the regulator is leaking, contact you supplier for
assistance. The regulator may need to be replaced.
Broken / non-functioning gauge
Replace
Unable to decrease delivery pressure
Create a slight flow of gas downstream of the manifold and
turn the regulator adjusting knob counter-clockwise.
