Calibrant Waste/Drain Fitting Replacement

Follow the procedure below in the listed order of steps to replace the

calibrant waste/drain fitting.

NOTICE Two options for repair are available depending on the condition

of the drain fitting. If the drain fitting can be cleanly removed, only the

replacement drain fitting is needed. If the drain fitting is heavily

degraded and cannot be cleanly removed, then the drain fitting kit is

required.

Required Parts/Tools

 Screwdriver, Torx™ T10

 Screwdriver, Torx™ T20

 5/16” or 8mm wrench

 7mm wrench

 P/N 1R76256-0105 – Drain Fitting only

 1R120590-6260 – Kit, Drain Fitting ISQ EC/EM (depending on

condition of original fitting/nylon block; please see NOTICE.

Step 10

Flip the fan box over to gain clear access to the fittings and mounting

nuts as shown in Figure 10.

Step 11

Disconnect the flexible tubing from the smaller drain fitting (calibrant

waste). Remove the fitting with either a 5/16th or 8mm wrench.

Verify that no debris from the original fitting is left in the nylon block.

Install the replacement fitting in its place.

Step 12

This step is only necessary is debris of the original drain fitting cannot be

removed from the nylon drain block.

Use a 7mm wrench to remove the mounting nuts and install the

replacement drain assembly (kit). If complete replacement of drain

assembly is not required, please proceed to Step 13.
