COMBO FILTER REPLACEMENT
Monitor the Moisture Indicator for a color change from BLUE to PINK. When the TX600 is new
and immediately after changing Combo Filters, the Moisture Indicator may show PINK. This is due
to the exposure to air and does not indicate inadequate filter performance.
Two Combo Filters are installed inside the TX600.
The Outlet Combo Filter can be identified by the presence of insulation around the outside. This
Outlet Combo Filter must be changed after every 50 hours operation OR when Moisture Indicator
shows "Bright Pink".
The Inlet Combo Filter does not have insulation around the outside. This Inlet Combo Filter must
be changed after every 25 hours operation OR when the Moisture Indicator show "Bright Pink".
Replace Combo Filters as follows:
Remove Rear Access Cover.
Disconnect Flare Adaptor Fittings at top and bottom of Filters.
Remove the mounting screws and remove Filters.
Remove the black insulation from the one filter and re-install on the new Filter.
NOTE... Remove the Valve Core from bottom port of the Filter which has the black
insulation installed around it. This Filter has a copper tube connected to the
bottom port for returning oil to the Compressor.
Install new Filters using the hardware removed earlier.
Connect Flare Adaptor Fittings to top and bottom of Filters.
Check for leaks and repair as required.
Replace Rear Access Cover.
