Enviro Maintenance Manual 2004
The clogged filter must be replaced and the system reset to resume normal operation. If this condition
occurs during normally operating hours rotate the OVERRIDE selector switch and the fan will come back on.
The systems can run in the OVERRIDE position for about 4 hours. (See the section the OVERRIDE switch)
If the system runs longer than 4 hours the fan will shut down. The filters must be changed and the system
reset. It is recommended that the filters be changed prior to the filter clogged light energizing. A filter usage
chart is attached to record when the filters are being changed. Using this chart a regular maintenance
schedule can be set up to ensure constant uninterrupted operation of the commercial kitchen.
Filter Removed:
Should the bag or box filters be removed during normal operation the KES unit is automatically shut down.
A pressure switch across the bag filters and box filters monitors a minimum pressure drop of 0.25” W.C.
When the filter is removed the pressure differential falls and the pressure switch is activated. The exhaust
fan shuts off, the “FILTER REMOVED” pilot light on the RPD10 or RPW10 energizes and the screen of the
LOGO controller in the RPD10 or RPW10 has a text message indicating “FILTER REMOVED/LOW
EXHAUST. To resume normal operation the filter must be replaced and the system reset. (See the section
the OVERRIDE switch)

Fire:
In the event of a high temperature in the ductwork leading to the KES unit or within the KES unit a firestat
located at the inlet of the KES filter section is activated. When the exhaust air reaches 160 F the firestat is
energized. The exhaust fan shuts off, the “NORMAL” pilot goes off, and a “FIRE” pilot energizes on the
remote RPD10 or RPW10 panel. Should the exhaust temperature continue to rise the fusible link melts and
closes the fire damper in the exhaust discharge of the KES filter section. This fire damper is always located
between the fan and filter section. The fire damper fusible link is rated at 165 F. Shut off all cooking
equipment and notify the fire department. To resume normal operation, replace the fusible link and reset the
system. An authorized SPRING AIR SYSTEM INC. service technician should be called to inspect the unit.
Override Switch: (located on RPW10 or RPD10 panel)
In the event that the filter clogged annunciation shuts off the KES unit during a peak cooking time rotate the
OVERRIDE SWITCH located on the RPW10 panel clockwise. The WARNING pilot light will energize and
the FILTER CLOGGED and NORMAL lights will turn off. This is a temporary override to allow for the
cooking equipment to be shut off prior to changing the filters. The systems can run in the OVERRIDE
position for 4 hours. If the system runs longer than 4 hours the fan will shut down. The filters must be
changed and the system reset. It is recommended that the filters be changed prior to the filter clogged light
energizing. A filter usage chart is attached to record when the filters are being changed. Using this chart a
regular maintenance schedule can be set up to ensure constant uninterrupted operation of the commercial
kitchen.
Once the dirty filter has been replaced rotate the OVERRIDE SWITCH to counter clock wise to resume
normal operation.
