Magnetic Drain Filter Cleaning
While cutting steels, a portion of the magnetic iron material is pulverized into small pieces and suspended in tank water. Without the protection of the magnets in the drain filter, those iron particles attract to the core of the low pressure pumps, gradually degrading the pump performances. The drain filter magnets get saturated and must be cleaned promptly to maintain its function.
Keep your drain filters clean is the first-defense for your low-pressure system. If clogged, the low-pressure system will be starved. Improper cleaning may bring more harm than good to the Low Pressure Pumps
[CAUTION]
Bacteria can build up in the standing water of the tank. Any injuries, even minor ones, should be treated with caution. If you have an open wound avoid contact with the water or wear gloves that do not expose you to the tank water.
Tools Needed
Gloves
Paper towels
Spare Parts needed
Spare Drain filters x 2 (recommended)
Procedure
1. The Magnetic drain filter is designed to slow down the drain rate as the magnets become saturated.
You will notice the machine pauses and displays “check drain filter and dump hose”.
You can also clean the magnetic drain filters between cuts and before the machine displays the error message.
2. Put on gloves. Open the door window, remove the rear tank cover
3. Reach into the water and locate the two drain filters. One of each side of the center column.
4. Unplug Drain Filter by pulling on the rubber neck.
If you have two spare magnetic drain filters, we recommend you putting the spare drain filters into the empty port at this point and carry on the cutting.
Leaving the drain filter port open may expose the low pressure pump to magnetic particles in the tank water.
5. After the filters are extracted from the machine, perform the following actions one by one:
Disconnect the silicone rubber base from the filter netting
6. Remove the magnet from the silicone rubber base
7. Use a paper towel to remove the soft layer of iron particles attached to the magnet. (The magnet is very strong and brittle, ensure do not bring it close to another iron or magnetic objects, and do not drop it onto the ground)
8. Rinse the magnet, netting and rubber base using the sprayer kit or under a sink
9. Put the magnet back into the silicone rubber base, and re-attach the netting to the rubber base.
10. Move on to the next magnet.
[Warning] never perform the cleaning on two magnets at the same time. Those magnets have strong attraction to each other. Putting one close to another may result in crushing or pinching injury, and cracked magnets.
11. Put the drain filters back to their respective fitting.
Ensure they are fully inserted and not coming off.
A break in the seal between the filter and the fitting can cause the iron to leak through. Always make sure the seal is completed fully.
12. Reinstall the rear cover. Always run with the rear cover installed so any buildup of abrasive does not directly affect the filters.
Notice
It is recommended to clean the Magnetic Drain Filter after every cut job.
[Notice] DO NOT wipe away any sludge! Wiping will push sludge into filter and may clog low-pressure piping.
