DESCRIPTION
1.
Dry state GCE SAFE-GUARD-5 (referred to as "FBA") complies with EN730 part 1, a safety
device for connection to and protection of cylinder regulators and manifold supply points.
Available in two versions, oxygen (0-10 bar inlet RH) and fuel (acetylene 0-1.5 bar, propane/
hydrogen/methane/natural gas 0-5.0 bar LH) with following features:
Sintered flame arresting element
FA
Non return valve to prevent the reverse flow of gases
NV
PV
Pressure cut-off device, activated by the pressure wave accompanying a flashback
TV
Thermal cut-off device, activated by heat to permanently cut off the gas supply
RM
Reset mechanism to advise if the unit has activated, and also to reset the unit.
INSTALLATION
2.
Use no oil or grease during the installation or use of this product.
At installation mark the month and year when the next annual inspection is due.
1. Ensure reset mechanism RM is in open position, with lever parallel to FBA body. If
lever is at an angle to FBA body press it down to parallel position. Never obstruct lever
MOVEMENT.
2. Connect inlet of FBA (1) to outlet of regulator after ensuring that the outlet pressure rating
on the supply regulator is lower than or equal to the inlet pressure rating on the FBA.
3. Connect hose to the FBA outlet (2), pressurise the system with downstream valves closed
and check all joints for leaks with approved leak detection fluid.
4. Once the FBA has been dedicated to a particular gas service it should not be changed to
be used on other gases
3.
AFTER FBA ACTIVATION
1. Turn gas supply to the FBA off. Identify reason for activation and rectify.
2. Reset the unit by pressing lever RM down. If this proves difficult due to pressure imbalance
then loosen inlet/outlet (1/2) to balance. If unit still fails to reset it is likely that thermal
device TV has cut-off, permanently, and the FBA should be discarded.

MAINTENANCE AND SERVICING
This FBA contains no user serviceable parts.
4.1 PERIODICAL CHECKS
This FBA must be checked at least annually for non return valve function, pressure cut-off
function, flow rate and leakage.
:
NOTE
To register first use and remind for next inspection please mark the label provided
on this product.
Ignoring or omitting periodical checks can lead to deterioration of FBA performance
and/or in case of damage or an unlikely loss of safety function - this could remain
unnoticed. Without periodical checks a risk of fire & explosion increases significantly.
The contact address of the nearest authorised service centre can be provided on request by
your GCE representative.
4.2 SERVICE LIFE
This FBA has a Maximum Service Life of 5 years counted from date of first installation.
Ageing, contamination and wear of internal components is time and conditions usage
dependant and exceeding the Maximum Service Life can result in increased flow resistance,
(GAS FLOW INTERRUPTED)
