Self Cleaning
1. During the wash cycle, water will be sprayed in the plenum and duct and surfactant will be injected at a
set frequency. The wash cycle will stop when the wash timer expires or when the Wash button is
pressed again.
2. The wash timer is factory set to 3 minutes and is adjustable through the Configuration Menu. The
surfactant is injected for 1 second at the start of each minute of Wash. This setting is not adjustable. If
equipped with CORE Fire Protection, the wash timer is not configurable through the ECPM03 control
board. Refer to the CORE Owner’s Manual for further information.
3. Hood filters MUST remain in place during the wash cycle.
4. The wash cycle can be initiated in several ways:
a. Manually, when the WASH button is pressed on the HMI.
b. Automatically, if the following conditions are met:
o Fans will need to go out of modulation mode either with the FANS button being pressed
or by the duct temperature cooling down and hysteresis value and timer are met.
o The fans will need to have effectively run cumulatively for a period of time longer than the
“Wash Min Fan Runtime” value configured under “Misc Options”. Preparation Time mode
and Cool Down mode fan time do not count towards runtime. The runtime is reset to zero
when the wash cycle is run.
o The amount of time elapsed since the previous wash cycle is greater than the “Wash Min
Interval time” value configured under “Misc Options”. That elapsed time is reset to zero
when the wash cycle is run.
c. If a Building Management System (BMS) is remotely controlling the fans through the external
input terminal IO1, when the Fans are turned ON and then OFF through the IO1 terminal, granted
that the fans are not maintained on by the duct temperature sensors or the fan button.
d. Through a digital Building Management System. R efer to the Building Management Owner’s
Manual for more information.
5. If the surfactant level is too low, an alarm will be triggered on the HMI. If the wash cycle is initiated
while this alarm is active, water will be sprayed but no surfactant will be injected. Refill Surfactant as soon
as possible
