NOTE:
Contamination caused by fluids

→ The (PDCC) system must never become contaminated by other fluids and dirt.
Remove Pentosin from the reservoir using a suitable syringe until the reservoir is virtually empty.

Lay a suitable cloth under the PDCC reservoir to prevent emerging Pentosin from getting onto the water lines. Loosen the hose clamps and pull the reservoir off the lines.
Fit new reservoir and secure the hoses.
Fill the reservoir with Pentosin and check the fluid level. → 430501 CHECKING FLUID LEVEL (PDCC)
