Startup | Maintenance | |
A) Foam surges and/or hose "bucks". B) Foamer will not draw chemical. C) Foam too wet. D) Foam does not clean properly (too dry). E) Using too much chemical. F) Water/chemical backing up into air line. G) Water backing up into chemical container. H) Air/chemical solution backing up into water line. | 1, 2, 3, 4, 6, 7, 8, 9, 10 1, 3, 4, 7, 8, 9 2, 3, 4, 6, 7, 8, 9, 10 1, 4, 6, 11 5 |

PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush the chemical out of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical strainer and replace if missing. |
