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’ Laborato ries 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 micron and submicron particles escape
Exhaust to
atmophere at
low level

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) inches box - 95 percent DOP filters.

KESF
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.

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.

The “NORMAL” operation pilot energizes on the RPW10 remote kitchen annunciation panel. After 30
seconds the RPW10 control circuit is activated. The RPW10 is a stainless steel panel located remote from
the SB or SBA panel. See Figure 5 for RPW10 wiring and dimensions. The KES exhaust fan motor is
energized through the terminals 5 & 4 to the LV10 J-Box located on the KESF fan section. See figure 11 for
internal wiring of the LV10 J-box. See figure 3 or 5 for a SB water wash panel.

Water Wash Ventilator System: AP, MP Panels
The KES unit off/on operation is controlled from the MP or AP water wash ventilator control panel. The fan
selector switch on the water wash control panel closes and sends power through terminals 3 & 4 to the
RPW10 remote panel to energize the exhaust fan through terminals 5 & 4 in the LV -10 J-Box. (The LV10 JBox is mounted on the KES-ISH filter section).
The “NORMAL” operation pilot energizes on the RPW10. After 30 seconds the KES control circuit within the
RPW10 remote panel is activated. See Figure 5 for RPW10 internal wiring. The exhaust fan motor is
energized through the terminals 9 & 4 to the motor starter located on the KESF fan section. See figure 11
for internal wiring of LV10 J-Box with RPW10 remote panel.
