In-Place Water-Wash Controls
Some electronic air cleaners are equipped with a water-wash system for in-place cleaning of the electronic cells. Operation of the water- wash system is governed by a control unit that includes a sequencing timer, water valve, detergent aspirator and valve, and a fan interlock switch to control the system fan during the wash cycle (see Figure 12-20). The timer controls the internal water and detergent valves
to provide automatic wash and rinse of the electronic cells. Typical hookups for a Honeywell W922 wash control are shown in Figures 12-21 and 12-22.
