Installation 

 

27

 
Install the Gas Lines 

Tool required: Open-end wrenches, 1", 1 1/8", 1 3/16" 

 

Gas lines are shipped with protective dust plugs.  Do not remove the plugs until the gas lines 
are ready to be attached.  All bending and routing of gas lines should take place with plugs in 
place. 

 

 

AVOID INJURY.

  Always wear eye protection when handling pressurized gas 

lines and other pressurized equipment.  Never apply heat to a pressurized gas 
line or other pressurized components. 

 

 

PREVENT EQUIPMENT DAMAGE.

  Damage to gas lines can result from 

crimping by repeated bending and repositioning. 

 

NOTE 

Be sure to have 99.995% pure helium gas available at the installation site in case 
gas needs to be added to the system.  See Refrigerant Quality in Specifications 
in this manual. 

 

1. 

Identification labels are furnished with the gas lines.  Before installing the gas lines, identify 
each with an appropriate label, SUPPLY (high pressure, color-coded red) or RETURN (low 
pressure, color-coded green) by applying the label adjacent to each Aeroquip coupling.  See 
Figure 6. 

 

NOTE 

Supply and return gas lines are identical.  Labels are used to prevent making a 
wrong connection at installation or at reassembly following maintenance. 

 

 

     Figure 6  Attach Identification Label 
 

2. 

Arrange the system components so that the gas lines will be protected from stress and 
traffic.  Observe the minimum bend radius of 180 mm (7") when routing gas lines.  Provide 
supports where needed. 

 

3. 

Remove the dust caps from the compressor’s supply and return gas couplings.
