Maintenance
General maintenance for CDR Series consists of scraping debris from settling tank,
periodically cleaning Y strainer before inlet of spin filters, and in some cases cleaning out
the discharge apex of spin filters. The settling tank should only be scraped when a
reasonable amount of debris has built up to the point where large quantities can be
removed at a time. DO NOT AGITATE SETTLING TANK UNNECESSARILY.
CLEANING Y STRAINER:
The CDR system is meant to filter coolant that has already passed through some type of
filtering conveyor. The Y strainer is there as a pre-caution to ensure large debris does not
make its way into the spin filters.
1. Turn CDR system off by pressing button 0, then turning off all power with
disconnect.
2. Allow system 30 seconds for any fluid above Y strainer height to drain.
3. Carefully remove Y strainer cap, let fluid drain into settling tank, and pull strainer
screen out.
4. Using proper PPE, knock any loose chips into chip hopper.
5. Clear screen using compressed air or water hose.
6. Reinstall Y strainer screen and cap and hand tighten only.
CLEANING FILTER VESSEL BASKET: (SEVERE DUTY MODELS ONLY)
For machines that do not have a filtering conveyor, a “Severe Duty” CDR is required that
includes the additional of a filter vessel with a cleanable mesh basket.
1. Turn CDR system off by pressing button 0, then turning off all power with
disconnect.
2. Open drain valve on filter vessel and allow system to drain.
3. Open lid on filter vessel and allow more time to drain if fluid level is above top of
basket.
4. Carefully remove basket and empty chips into hopper.
5. Basket screen may need to be cleaned before re-installing.
6.
Reinstall basket carefully and make sure it’s seated properly.
7. Clean O-ring and mating surfaces on top of filter vessel.
a. If O-ring is damaged, replace with a new one.
8. Reinstall filter lid and tighten all bolts snug. Tools are not generally required to get
a proper seal.
9. CLOSE DRAIN VALVE BEFORE TURNING SYSTEM BACK ON.
