KES OPERATIONS AND MAINTENANCE MANUAL
INTRODUCTION
The SPRING AIR SYSTEMS INC. kitchen Enviro system (KES), Exhaust Cleaning Assembly for Kitchen
Exhaust Duct, “Enviro Unit” is ULC and UL listed for use in a commercial kitchen exhaust system. KES
units are available in sizes ranging from 1,000 CFM to 40,000 CFM for indoor or outdoor applications.
The primary function of a KES Enviro unit is to filter the grease, lint and dust particles and remove the odor
from the exhaust air.
The Underwriters’ Laboratories of Canada Limited (ULC) listing allows the use of non-NFPA-96 exhaust
ductwork after the exhaust air is discharged from the KES unit. In other words the discharge ductwork can
be treated similar to standard HVAC ducting. Also after the kitchen exhaust air has been treated with the
KES unit the exhaust can be discharged outdoors at low levels.
The Underwriters Laboratories Inc. (UL) listing allows the kitchen exhaust air to be discharge to atmosphere
at low levels.
Prior to any installation the installer must seek approval from the authorities having jurisdiction.
THE SYSTEM
The grease-laden air rises from the cooking equipment into a UL or ULC exhaust hood. The exhaust hood
removes some of the airborne grease particulate. Typically most micronand submicron particles escape
into the exhaust ductwork. The exhaust ducting is connected from the hood to the inlet of the KES Enviro
unit. This exhaust ductwork must be supplied and installed in accordance with the NFPA-96 code.
KES System Schematic
Figure 1
Within the KES unit the exhaust air travels through three stages of particulate filters:
1Two (2) inches pleated-30 percent ASHRAE 52-76 prefilters.
2Twenty-one (21) to twenty-two (22) inch bag-90 percent ASHRAE 52-76 filters.
3Twelve (12) inchesbox -95 percent DOP filters.

Once through the particulate filter sections the exhaust air enters the optional odor removal section. The
odor section is only required when discharging cooking smells may be offensive. This section consists of
two optional odor removal systems.
1.Odor Cells filled with activated alumina impregnated with potassium permanganate. The odor is controlled
through a combination of sorption and the chemical modification of the gaseous contaminates. The
odor media is non-toxic and non-flammable.
1.Odor spray solution. The odor is control by spraying an odor reducer into the exhaust air stream
intermittently during the operation of the cooking systems.
2. KES-ISH and KESF Enviro components
Figure 2
The exhaust air is discharged from the KES unit through a single width, single inlet (SWSI) or double width,
double inlet (DWDI) exhaust fan. The discharge ductwork transfers the exhaust air outdoors.
CONTROL SYSTEM
Water Wash Ventilator System: SB, SBA Panels
The KES unit off/on operation is controlled from the SB, or SBA water wash ventilator control panel. Power
is fed to the RPW10 panel through terminals 1 & 4. When the fan selector switch on the water wash control
panel closes a signal is sent through terminal 3 to the RPW10 panel to activate the KES unit.

Pressure switches have been installed to determine when the filters are totally used andmust be replaced.
As the filter reaches the grease loading capacity the static pressure across each filter increases. When the
maximum static pressure is reached the pressure switch is activated. The exhaust fan shuts off, the
“NORMAL” pilot energizes, and the kitchen remote panel annunciates a filter-clogged condition. (The
remote panel indicates which stage of filters has clogged; PREFILTER, BAG FILTER, or BOX FILTER.) In
addition the screen of the LOGO controller in the RPD10 or RPW10 has a text message also indicating
which filter is clogged.

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

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 andnotify 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.

ODOR SPRAY SYSTEM
Operating and Maintenance
The Spring Air Systems Inc. odor spray unit has a one-year warranty from startup. The two timers, cycle
timer B01, and spray timer B02, are factory set (5 minute cycle and 2 second spray) and then adjusted
during startup to the odor reducing intensity required for the application. The B01 cycle timer is generally set
between 5 to 10 minutes. The B02 spray timer is generally set between 2 to 60 seconds.
How does it Work?
The odor spray setting is a qualitative measurement. The spray timers are field set to provide adequate
odor reduction for the installation. This is completely subject to what a particular person feel is an
acceptable discharge odor.
During the spray timer activation the combination air compressor and air-atomizing nozzle injects a volume
of odor solution into the exhaust discharge. This solution is carried along the discharge duct and vented to
atmosphere. The spray solution chemically activates with the kitchen exhaust air to reduce the kitchen
exhaust odors. As the solution is carried down the duct some adheres to the duct walls. We will call this the
spray residue. During the cycle time when the spray is not activated this spray residue continues the odor
reducing process as the exhaust air passes. Therefore installation with longer discharge ducts can normally
use a longer cycle time because there will be more spray residue. A shorter run of discharge duct usually
results in shorter cycle time.
A. When adjusting the timers the object is to use as little spray solution as possible to provide adequate
odor reduction:
1. First adjust the spray cycle, B01 timer.
2. Reduce this setting by ½ of the original cycle setting and check the operation. If ½ proves
adequate, increase the cycle back to ¾ of the original cycle setting. If this is adequate increase to
7/8 of the original setting and so forth.
3. If reducing the setting by ½ is not adequate decrease the cycle to ¼ of the original setting. If this is
not adequate adjust the spray timer B02.
a. Increase the spray time B02 in increments of 5 seconds. After each 5 second increase
evaluate the quality of the exhaust discharge air to determine if it is acceptable to the user.
b. When the spray timer setting equals the cycle timer settings the spray will be continuous.
The maximum setting of B02 should not exceed the cycle timer B01.
The odor spray bottle must be changed regularly depending on the length of time set on timers B01 and
B02. The odor spray line from the spray bottle to the spray nozzle must be cleaned every 6 months in a
water and detergent mixture. The compressed air gauge should read between 10 and 15 psi. When the air
gauge is reading below 10 psi clean out the compressed air line. If the pressure is still low proceed to the
next step compressor maintenance.
When there is odor in adjoining floors or office spaces
A kitchen located in the interior of an office building must be very negative to keep the kitchen odor within
the kitchen. We recommend the kitchen be a minimum 20% negative. The fresh air supply is 80% of the
total exhaust air from the kitchen space. When there is odor in adjoining spaces check the following.
1. The kitchen is not negative enough to keep the smell of the kitchen in the kitchen. If this is the
case the odor is usually present all the time, even when there is no cooking. Reduce the amount of
fresh air to the kitchen by adjusting the supply fan volume.
2. The kitchen may be connected to the same building A/C unit as the rest of the floor. If this is the
case the return air grilles in the kitchen draws the kitchen odor to the main A/C unit and disperses
the odor throughout the floor. The main A/C return must be blocked from the kitchen and put on a
separate A/C unit.
3. The floor above the kitchen have odor. There are three possibilities.
a. The exhaust shaft is not sealed and the kitchen exhaust is leaking out onto the floors
above the kitchen. Either adjust the amount of odor spray per section "A" above or install
