Cleaning & Maintenance
5.01.2 E.A.C. Filter Cell Cleaning - continued
4. Carefully move cell to sink and rinse thoroughly, using hot water spray. Rinse ONLY, DO NOT scrub
with brushes.
5. Stand cell upright on end on a drain board, w/contact plate up ... allow it to drain and air dry
overnight. The cell must be completely dry before being replaced in hood unit. If desired, a small
electric fan can be used to blow across the cell to help expedite drying.
6. Before replacing cell in the hood, inspect for broken/missing ionizer wires and bent fins. Broken
or missing wires need to be replaced promptly. Bent fins may be straightened by hand so that no
fins are touching adjacent fins.
IMPORTANT! ONLY Simple Green® Crystal Foaming Cleaner/Degreaser is recommended by GILES for cleaning the
E.A.C. cell in this manner. Other spray cleaners have not been evaluated and may contain corrosive ingredients that
may damage the metal, causing cell to fail or not perform properly. Such damages are not covered by the factory
warranty.
B. Alternate Cleaning Method - Soaking
The factory-recommended product to use for cleaning the E.A.C. cell in this manner is Simple Green® Pro-HD. It is a
readily available, biodegradable, non-toxic degreasing cleaner that is safe for use on aluminum. It performs well to clean
the cell when diluted at a 1:12 ratio (e.g. 1/2 gal. cleaner to 6 gals ambient water).
DO NOT use DISHWASHING DETERGENTS or CORROSIVE CLEANERS as they can contain ingredients that may damage
the metal cell components, causing failure or unsatisfactory performance. Such damages are not covered by the
factory warranty.
1. Cleaning with this method requires a suitable, leakproof container, such as a tall trash bin, recycle bin,
plastic tote, etc. that is large enough to hold the cell along with enough degreasing solution to
completely cover and soak it, either standing on end, on edge, or lying flat.
2. Fill the container with fresh water to a level that will cover the cell. Measure water as filling
and note the quantity. Add Simple Green® Pro-HD in the ratio of 1:12 to the water (e.g. 8
gals of water would require .67 gals (2 qts+21 ozs) degreaser. Stir solution to mix.
3. After preparing a quantity of degreaser solution sufficient to completely cover the cell in the
soaking container, hold cell by the contact plate, frame, or handle and carefully place it into
the solution. Be sure that it is fully submerged.
4. Allow cell to soak for approximately 20 minutes (no more than 30 mins), then lift it slightly
and briefly agitate it in the solution to help dislodge grease residue.
5. Carefully remove cell from container and follow Steps 4 thru 6 as detailed in Method (A).
NOTE:
The degreasing solution may be used multiple times ... cover container with a lid or other suitable cover when not in
use to prevent contamination. Discard and replenish solution when a greasy film seems to remain visible, floating on
the liquid. When soaking, always ensure that solution completely covers the cell ... add some water if needed.
