Graco Proportioning System 26R332

Follow the Pressure Relief Procedure

Close the Fluid Inlet Valve (XA) at the pump inlet

Place a container under the strainer base to catch fluid when removing the strainer drain plug (ZB)

Remove inlet cap (ZC) and inlet strainer screen (ZA) from the strainer manifold

Flush the screen with compatible solvent and shake it dry

Inspect the screen for blockage

Inspect the gasket and replace as required

Install the strainer plug (ZB) with the screen (ZA)

Open the fluid inlet valve (XA)

Check if the TSL fluid has turned into a gel

Check if the color of the TSL fluid has darkened

Check if the TSL fluid is diluted with isocyanate

Describe the operating environment conditions

Is a TSL fluid change required based on the inspection?

Change the transfer pump type to Air

Change the transfer pump type to Electric

Calibration of Both Transfer Pumps

Are you calibrating both transfer pumps?

Repeat steps 2–3 for the other transfer pump motor if calibrating both

Confirm there is no or low inlet pressure in the transfer pump by opening the recirculation lines (R)

Enter the current fluid pressure setting

Is the fluid pressure within the optimal range?

Enter the current fluid temperature

Is the fluid temperature within the optimal range?

Select the mix chamber size based on desired flow rate and fluid viscosity

Follow Pressure Relief Procedure

Remove and clean the TSL fluid reservoir

Lift the TSL fluid reservoir (R) out of the bracket and remove the reservoir from the cap.

Flush contaminated fluid out of the lines

Manually cycle the peristaltic pump (PP)

Flush the reservoir with clean TSL fluid or replace it with a new reservoir

Refill and reassemble the TSL fluid system
