D.
STORAGE:
If your Parts Washer is not going to be used for an extended
period of time (3 months, 6 months, a year or more !), it should be
properly prepared for storage, to avoid damage to the unit.
Even though the soap and water solution in the washer has Rust
Inhibitor in it, during a period of non-use the soap and inhibitors
can precipitate out or settle, and your cabinet will rust and corrode!
Also, any water left in the tank will induce moisture to cling to the
walls inside the cabinet, where rust and corrosion will occur.
1. You will need to drain the unit of all water and soap solution.
Waste Water should be disposed of by an approved means.
Check with your local authorities !
2. Remove all debris inside of cabinet and clumps of soap that
may have settled to the wash tank floor.
3. Hose out the cabinet walls and tank to rinse off any corrosive
substances that may be remaining.
4. Allow the inside of cabinet to DRY thoroughly.
(spray wash area, turntable, and wash tank)
5. Prop open the door of washer, while it is in storage and not
being used, so air can circulate into cabinet to keep it dry !
