Gardner Denver Oil/Water Separator CTS30

Shut off condensate flow to Inlet Diffuser Assembly

Unscrew the four Socket Head Cap Screws that hold the Diffuser to the Vessel

Lift up the Diffuser and move it out of the way so you can remove the Sediment Chamber

Grasp the edges of the Sediment Chamber and slowly lift it from the vessel

Tip the Sediment Chamber slightly to slowly pour the contents through the Separation Filter and back into the vessel until the liquid is emptied

Remove the Separation Filter from the recess inside the Sediment Chamber and discard

Clean the dirt, rust and scale from the Sediment Chamber. Reinstall a new Separation Filter into the recess

Seat the Sediment Chamber into the vessel by slowly pouring tap water into it until the water exits the discharge holes in the Chamber walls

Remove and replace the Expansion Chamber element located on top of the Diffuser Assembly

Take the empty Sample Jar and collect a sample from the Sample Valve located above the Oil Container.

Hold both the Sample Jar and the Reference Jar to a light for a visual turbidity comparison.

Keep a spare Pre-Absorber and Carbon Bed(s) in stock to avoid change out problems.

Change the Pre-Absorber and Carbon Bed(s) when the compared Condensate Sample appears cloudy.

Pour the Condensate Sample back into the Pre-Absorber Chamber.

Wash and dry the Sample Jar before returning it to the Placement Well.

Note: The Sample Valve extracts the condensate sample 2/3rds of the way through the Carbon Bed. This provides enough time and security for replacing the Carbon Bed(s) before PM violations should occur.

Sign off on the maintenance procedure

Prepare the replacement Carbon Bed(s) and Pre-Absorber for service

Remove them from their plastic bags

Thoroughly hose down the Pre-Absorber & Carbon Bed(s) while rolling them until the water runs clear

Shut off the condensate flow to the Inlet Diffuser Assembly and remove the Access Lid

Use a polypropylene pad to adsorb and remove any oil that is floating on the surface water in the Carbon Chamber(s)

Grab Carbon Bed Handles (CTS30/60) and slowly lift bag(s) out of chamber

Suspend bag(s) over chamber tor a couple of minutes to drain

Install new Pre-Absorber & Carbon Bed(s). (Install the left side Carbon Bed first on model #CTS60 thru CTS240)

Reorder a spare Pre-Absorber & Carbon Bed(s) set

Check the Oil level in the translucent Oil Container

Empty it when the oil level reaches 3/4 of capacity

Verify that the bright red Flow Indicator is retracted inside the Access Lid

See Troubleshooting Section if the Flow Indicator is not retracted
