AVOID INJURY.
When handling pressurized gas lines and other pressurized
equipment, always wear eye protection. Never apply heat to a pressurized gas
line or other pressurized components.
DAMAGE TO GAS LINES
can result from crimping by repeated bending and
repositioning.
AVOID GAS LEAKS.
Check the condition of the gasket seal on the male half of
each Aeroquip coupling. Be sure the gasket seal is in place and the sealing
surfaces on both the male and female halves are clean before connecting.
Replace the gasket seal if it is damaged or missing.
AVOID GAS LEAKS.
Keep the gas line couplings aligned when making or
breaking a coupling connection. Leaks can occur due to the weight of the gas
line or due to a sharp bend near the connection.
NOTE
Retain
the
threaded protective caps
and
plugs to re-cover
the
couplings when they
are not in use. They protect the couplings from damage and prevent entry of
contaminants.
1.
Arrange the system components so that the interconnecting gas lines will be protected from
stress and traffic. Observe the minimum bend radius. Routing of gas lines should consider
the need for gas line supports.
2.
Remove the dust caps from the compressor supply and return gas couplings.
3.
Remove the dust plugs from the couplings on one end of each of the supply and return gas
lines.
4.
Connect the supply (red) and return (green) gas lines directly to their corresponding
compressor gas couplings.
5.
Connect the supply (red) gas line to the gas supply coupling on the compressor. Use two
wrenches to tighten the coupling. See Figure 6.
Torque all Aeroquip couplings to 4.87 ± 0.7 kgf m (35 ± 5 ft. lbs.). Tighten each coupling
before proceeding to the next one.
