SAMPLING COOLANT FOR ANALYSIS

1.   Bring the compressor up to operating temperature.

2.   Stop the compressor.

3.   Isolate the compressor from the external air system.

4.   Press the emergency stop. Fixed speed compressors 

can take more than two minutes to fully de-pressurize 
once stopped.

5.   Draw a sample from the separator tank port using a 

pump kit. DO NOT draw a sample from the drain port 
or oil filter.

Use a new hose on the pump for each sample. Failure to do 
this can give false readings.

See Figure 2.

CHANGING COOLANT FILTER

1.  Loosen filter with the correct tool.

2.  Remove the filter from the housing.

3.  Place the old filter in a sealed bag and dispose of in a 

safe way.

4.  Clean the mating face of the housing taking care to 

avoid any particles entering the machine.

5.  Remove the new Ingersoll Rand replacement filter 

from its protective package.

6.  Apply a small amount of lubricant to the filter seal. 

Screw the new filter down until the seal makes 
contact with the housing, then hand tighten a further 
half turn.

7.  Start the compressor and check for leaks.

CHECKING SEPARATOR ELEMENT

With the compressor running on load, check the separator 
differential pressure via the controller. It will be necessary to 
change the element if the differential pressure equals zero or 
exceeds 1 bar (15 psig).

CHANGING SEPARATOR ELEMENT

1.  Remove the fitting that holds the scavenge tube into 

the tank and withdraw the tube assembly.

2.   Disconnect the piping from the tank cover. Tag the 

lines if required. Remove all the bolts securing the  
over to the tank except the bolt opposite the pivot 
bolt which should be left engaged by 2-3 threads 
with at least 6.5 mm (0.25 in) clearance from the screw 
head to the cover. Rotate the jacking bolt clockwise 
until the cover lifts off the tank at least 2 mm (0.08 in) 
all the way around the tank. Remove the remaining 
bolt. The cover can now be rotated to allow access to 
inside the tank. 

3.   Carefully lift the separator element up and out of the 

tank. Discard the faulty element.

4.   Clean the sealing surface on both the tank and its 

cover. Check the tank to be absolutely certain that 
no foreign objects such as rags or tools have been 
allowed to fall into the tank. Lubricate a thin layer of 
coolant on the separator seal top and bottom before 
installing a replacement element down into the tank 
after checking the new element seal for possible 
damage. Center the element within the tank ensuring 
that it is fully seated in the sealing groove. Rotate 
the tank cover back into position taking care not to 
damage the seal, and locate the cover using two bolts 
but do not tighten down.

5.  Loosen the jacking bolt to fully disengage the threads 

and tighten the cover bolts in a cross-pattern to 
prevent over-tightening one side of the cover. An 
improperly tightened cover will likely result in a leak. 
See Figure 3

6.  Inspect the tank scavenge screen and orifice. Clean if 

necessary following the instructions below.

7.   Install the scavenge tube down into the tank until the 

tube just touches the separator element and then 
raise it 2 mm (0.10 in). Ensure tube is not raised less 
than 2 mm (0.10 in) or more than 3 mm (0.125 in). 
Tighten fittings.

NOTICE

Take extreme caution to not force the scavenge tube 
into the tank. This could potentially damage the 
separator element.

8.  Install the piping in the original position.
