INSTALLATION
Step 1
Protect the connector from damage and dirt by keeping it in the original packaging until you are ready to use it.
Step 2
Check that the connector part number and delivery notes (if applicable) comply with the application.
Step 3
Connect the hose securely and leak-tight to inlet B (Figure 1). Tighten to a max torque of 15 ft-lbs.
A higher torque can result in damage causing leaks when the system is pressurized.
Ensure that the connectors cannot be damaged when loading and removing the cylinder.
Step 4
Review total function:
• Check leak-tight seal
• Check if collets open and close properly by actuating
the connector several times
• Check if connector marking complies with the
application
• The FasTest connector is ready to operate
Note
Avoid lateral forces like short connecting hoses because
this could cause leakage.
Figure 1. Torque to maximum 15 ft-lb
!
CAUTION: Do not over tighten.
Over tightening could break
connector and cause injury to operator.

Step 2
When making a connection:
• Ensure that the connector is in the fully open position
and in direct contact with the front of the valve before
moving the actuator
• Align the connector to the thread to prevent damage
to the front seal from sharp edges of the valve
• Place the connector onto/into the valve until it stops.
DO NOT USE FORCE!
• Rotate the bail to engage the connector. Do
not actuate the loop with excessive force. If the
connection is made correctly, it will connect with
relative ease
• Ensure that the actuating loop has traveled to a
position below parallel to the connector body. Check
to make sure the collets are fully engaged.
(See good vs. bad connection photos, pages 4-5)

Incorrect Handle Positioning
Step 4
Connect. The safety pin protrudes out (engages) at
a pressure of approximately 150 psig, depending on
connector age, cleanliness and lubrication.
Step 5
Disconnect. Disconnect only when the connector is
depressurized and the safety pin retracts.

PRESSURE. (See Safety Pin care in Maintenance
section of this manual).

Main Seal
The main O-ring seal must be replaced at least every 1000 cycles. FasTest recommends a daily visual
inspection of the sealing O-ring, located at the tip of the lling nozzle. Inspect for tears or cracks in the
O-ring surface. Replace O-ring if tears or cracks are visible or veried. Some applications require more
frequent seal changes.
MAINTENANCE
Good Maintenance Practices
• CGA standards for medical oxygen lling, CGA 870 and CGA 346/540 series connectors may require
periodic lubrication. Use Krytox or approved equivalent only.
• Maintain accurate and complete product maintenance records.
• In addition to these suggested maintenance guidelines, your companies overall safety and maintenance
requirements should be applied to FasTest gas connector products.
• It is recommended that gas connector products involved in high-volume lling be returned to FasTest for
a complete product inspection and required maintenance every 5 years.
• Adhering to a consistent product maintenance program will minimize product returns for inspection as
well as required maintenance costs.
• Minimize the use of soap solutions sprayed directly onto connector. These types of solutions cause
a build-up that can hamper proper connector operation. Also, avoid contacting connector with any
petroleum base chemicals that can cause product contamination.
• DO NOT EXCEED THE MAXIMUM OPERATING PRESSURE AS STATED IN BOTH PRODUCT
LITERATURE AND ON ALL INDIVIDUAL CONNECTOR PRODUCTS SOLD BY FASTEST.
Connector Maintenance
The following maintenance guidelines apply to all FasTest gas connector products. Additional guidelines that
apply only to a specic CGA standard connector are noted.
• A daily, weekly and periodic inspection of the connector by a competent person is recommended.
Inspection should include wear of swivel joints, damage to the body, leak-tightness, ease of operation,
sufcient lubrication, wear, dirt accumulation and damage. (See Maintenance Checklist)
• If upon inspection a problem is noted, refer to the Troubleshooting Guide at the end of this manual.
DO NOT DISMANTLE THE CONNECTOR.
• The manufacturer (FasTest) should refurbish connectors after 50,000 ll cycles.
• You may use only original FasTest spare parts that are designed for the application and are subject to
strict quality control. See Warranty.

Bail Handles
FasTest recommends a periodic inspection and tightening
of the actuator handles on applicable CGA standards. If
screws are loose, tighten to 8-10 ft-lb.
Do not over tighten screws.
A drop of Loctite 242 on the threads of the screw is
appropriate.
Safety Pins
Safety pin operation must be inspected daily. With
actuator handle connectors, the safety pin will protrude
out during the lling cycle at approximately 150-psig. The
safety pin retracts back into the connector body upon
completion of the ll/vent cycle. The actuator handle will
ip back easily when the connector is depressurized and
the safety pin retracts. Failure to wait may cause damage
to the safety pin.
If the safety pin does not function properly, the pin
assembly may require cleaning and lubrication. Or, if bent,
the safety pin will require total replacement. Attempting to
disconnect the connector while pressurized contributes to
the bending of the safety pin.
DO NOT ATTEMPT TO DISCONNECT ACTUATOR
STYLE CONNECTORS WHILE UNDER PRESSURE.

MAINTENANCE
Maintenance Checklist
Daily
Inspect for Leak-tight seal
• The main seal must be replaced more frequently depending on wear. Dismantling of the
connector for this purpose is not required. It is recommended that an O-ring pick be used for
removal to avoid damage to the groove
• Clean groove if required and insert new O-ring
Inspect for correct function.
• Does the safety pin properly protrude and lock the connector under pressure?
• Does the safety pin move backwards when the system is depressurized?
Weekly
Inspect for correct function
• Inspect the correct engagement of the collets
• Check the connector’s collet thread with gauge
• Check for any bent or missing components
Periodic
• Inspect that all threaded components are tight and properly torqued
• Check for any bent or missing components
• Check for proper actuation of handle, collets and all moving components
• Check for leaks
