To ensure that the CW1 remains in proper working order, keep the device clean, and never leave the tank with isopropyl alcohol inside of the device when the machine is off / not being used. Clean any resin drops or stains immediately, before they solidify.
The CW1 is designed to withstand a moderate IPA spill - the liquid will pour through the device. It’s a good practice to keep a plastic tablecloth under the device in case of spillage.
In case a spill occurs and the liquid pours into the CW1, disconnect the machine from the power supply, wipe off any remaining IPA from the device’s surface and wait for a couple of hours (e.g. 2-3) until the isopropyl alcohol evaporates completely from the inside. The machine has a hole in the bottom plate through which the IPA will pour out. High-quality isopropyl alcohol will not damage the electronics inside the device.
Please note that isopropyl alcohol is consumable and it will become saturated with resin over time, which is normal. Only when you notice that the washing performance is decreased, consider exchanging the IPA in the CW1 tank - this usually happens after several months of use, depending on the frequency of usage.
See your country’s laws regarding safe and appropriate disposal methods of IPA in your location - usually, it should be treated as a hazardous liquid, because it will also contain photoinitiators, polymers, and oligomers from the resin. You can usually find places for disposing of dangerous liquids near gas stations or fire stations.
