INTRODUCTION
ir quality is becoming a major concern in America’s large
A
cities and as a result, many commercial kitchens will require pollution control equipment in their exhaust systems to
comply with the increasing demands of environmental control
agencies. In addition, pollution control equipment is being used
for kitchens in high-rise buildings allowing the exhaust to discharge out the side of the structure which saves the cost of
running the duct up many floors to the roof.
Pollution control in kitchen exhaust systems has typically
been accomplished by any one of the following methods gas fired incinerators, scrubbers, filtration units or electrostatic precipitators. Incinerators and afterburners literally burn
the pollutants and, while effective, can be very costly and
hazardous to operate. Scrubbers consist of a water bath and
extraction baffles to remove the pollutants and though quite
effective on grease removal, they typically require the addi-
tion of high efficiency filters to abate smoke below control
agencies’ standards. Filtration units use a series of impinge-
ment filters to remove the pollutants and if done properly can
be quite effective on both smoke and grease.
The Gaylord pollution control unit, trademarked “ClearAirTM”,
can be manufactured with either electrostatic precipitation
(ESP) or Filtration (TPF). Gaylord Industries, Inc. has been
manufacturing ESP’s specifically designed for commercial
kitchen exhaust systems since the early 1970’s, longer than
any other manufacturer. However, when initial cost is a greater
concern the TPF unit is a sound alternative.
The ClearAirTM TM ESP unit is available in several configura-
tions, as illustrated on the following pages, ranging in capac-
ity from 1000 to 32,000 CFM (472 to 15,102 L/s). Most mod-
els can include an exhaust fan and odor abatement equip-
ment as an option.
Basic Facts About Smoke
Smoke particles are extremely small and not visible to thehuman eye unless thousands of them are grouped togetherto form what we see as smoke. Individual particles are mea-sured in units called microns and one micron equals 1/25,400of an inch (1/64,516 of a cm).
Smoke generated by commercial cooking equipment has a
particulate size of between 0.3 and 0.8 microns and it is these
very small particles that smoke abatement equipment must
remove from the airstream. The amount of smoke being dis-
charged from a kitchen exhaust duct is measured in terms of
its density , referred to as opacity - the degree to which emissions block light. A 100% opacity level would be solid black
and 0% would be perfectly clear. Control agencies that have
adopted smoke pollution ordinances are requiring an opacity
level of no more than 20%, which is a very light blue smoke.
Typically , heavy smoke producing cooking such as charbroiling, creates an opacity level of 60% to 70%. Opacity readings are taken by the human eye by viewing the smoke being
discharged and then assigning a percentage of opacity to
what is seen. Though this method is quite subjective, it is
the method practiced by control agency inspectors who are
trained and certified in determining opacity percentages. Other
more technical methods of determining opacity or particulate
density are achieved through the use of opacity meters and
cascade impactors. This level of analysis is usually referred
to as source testing. Control agencies occasionally require
this type of analysis and if so, the testing is conducted by
state certified contractors which can be quite costly and timeconsuming. The efficiency of an TPF is based on how well it
reduces the opacity level of a given airstream.The Gaylord
ClearAirTM unit will reduce the opacity level below 20%,
thereby meeting the requirements of environmental control
agencies.
Basic Facts About Odor
Cooking odors (molecules) generated by the combustion of
animal and vegetable matter result in an extremely complex
mixture of reactive organic gases (ROG’s). A small percentage
of these odors may be absorbed by the grease particles but the
vast majority exist separately in the airstream. The ROG molecules are much too small to be removed by any type of filter and
therefore, other methods must be used. There are several meth-ods with which to manage the odor. One method is to use amedia bed. The two most popular types of media bed are acti-vated charcoal, which absorbs and retains the odor molecules,and the use of an odor-oxidant media (potassium permangan-ate) which oxidizes the molecules to solids and then retains
them. The other method involves the use of a liquid delivered with
a finely atomized spray. This spray performs a similar function to
potassium permanganate in that it adsorbs or chemically neutralizes odors. This process has the benefit of the end user being
able to adjust the amount of spray and thus the effectiveness and
cost of the odor control.
The life of the media bed type of odor control is dependent
upon several factors such as how much media is used, type
of odor, amount of odor molecules, grease loading and air
temperature. Typically, any of the above mentioned types of
media can remove 85% - 90% of the molecules. Determining
the efficiency of odor control can be very subjective, as testing
is usually conducted by the human nose. More scientific testing is available through ROG analysis, but this involves considerable costs.
Grease Removal - The Important First Step
Grease particles are also measured in terms of microns and
grease generated by commercial cooking equipment has a
particulate size of 10 microns and up. Pollution control equipment is not limited to removing smoke particles, but will also
remove a majority of the grease particles remaining in the
airstream. Therefore, the grease extraction efficiency of the
exhaust hood plays an important role in the operation and
performance of pollution control equipment.
Removal of grease particles before they reach smoke and
odor control equipment will significantly increase the smoke
abatement efficiency and the life of the odor abatement media. It is highly recommended that a Gaylord CG3 Series
Ventilator be used with the ClearAirTM unit as it has a grease
extraction efficiency of 95%. Other high efficiency exhaust
hoods and standard filter type hoods may be used with the
ClearAirTM unit. Contact Gaylord Industries for details.

cables, or chains. Consult the mechanical or structural engi-
neer before moving the unit across the roof deck.
INSTALLA TION CODES
This unit requires external plumbing and electrical connections
to be made in the field. It is recommended that the Authority
Having Jurisdiction (AHJ) be consulted regarding local codes
and installation procedures. Gaylord Industries is not responsible for obtaining necessary approvals and permits which may
be required for installation, nor is it responsible for verifying that
the unit has been installed in accordance with national, state,
and local codes. In the absence of locally adopted codes use
the current editions of the N ational Electrical Code and the
Uniform Mechanical Code. Connections of the exhaust duct to
the inlet and outlet of the ClearAirTM unit must be fully welded to
comply with NFPA-96.
INST ALLATION PRECAUTIONS
1. The services of qualified contractors are essential for safe
and proper installation of this equipment.
2. The air volumes and external static pressures that are
listed on the unit are for the middle of the operating range of
the filters. The initial air volume should be at least 10% higher
than the listed CFM. As the filters load up the air volume will
drop. This is inherent to this type of unit. If the unit is set up
at or below the design CFM, as the filters load up, the kitchen
hood may experience smoke loss problems. Please consult the factory if you have questions.
3. The unit is designed for installation on a level surface.
4. When installed in an enclosed space a fire rated enclosure may be required for the unit and associated duct work.
Consult the Authority Having Jurisdiction.
5. Consult the Authority Having Jurisdiction regarding requirements covering the point of termination of the exhaustoutlet of this unit. Minimum distances must usually bemaintained between the exhaust outlet and any outside airintakes and/or adjacent structures or property lines.
6. Do not apply power to the unit until all electrical connec-tions have been made and a pre-start-up preliminary inspection has been completed.
7. Allow a minimum of 36 inches clearance in front of the
filter access door and electrical compartment door for service and routine maintenance per NEC.
SHORT TERM STORAGE
Units that include media bed odor control are provided with
KOR48/carbon media which is shipped separate from the
unit. KOR48/carbon media must be stored in a dry place
with less than 95% relative humidity .
EXHAUST FAN RECEIVING AND STORAGE
If the unit is equipped with an exhaust fan it must be relubricated as soon as it arrives. T o prevent corrosion all bearings should receive grease and be rotated the first of every
month. Rotate the wheel several revolutions every three to
five days to keep a coating of grease on all internal bearing
parts. Turn the wheel by hand while greasing bearings. A
clean 1/16" bead of grease must appear on each side of each
bearing. Refer to specific bearing lubricating instructions on
the fan. Also, refer to bearing lubricating instructions found in
the exhaust fan section of this manual.
Bearings which are to be stored or idle for an extended period of time should be wrapped in a neutral grease-proof paper, foil, or plastic film. Compounds can be recommended
by the bearing manufacturer to provide protection for several
months to several years.
After long-term storage, grease should be purged from the
bearings and fresh grease injected prior to start-up.

SMOKE CONTROL
Principle of Operation
The ClearAirTM TM Pollution Control Unit removes smoke particles
by electrostatic precipitation. The principle of operation of electrostatic precipitation is actually quite basic. The electrostatic cell
is made up of a series of aluminum plates spaced approximately
1
/4” (6.35mm) apart and the number of cells used is determined
by the air volume and the type of cooking equipment involved.
Every other plate is energized with 5000 volts of D.C. power and
the alternating plates are grounded. At the entry point of the cell
is a series of thin wires spaced approximately 4” (101.60mm)
apart. These wires, referred to as ionizing wires, are energized
with 10,000 volts D.C. and as the smoke particles enter the cell
and pass over the wires they receive a positive charge. As the
charged particles continue through the cell, the positive plate re-
pels them and the negative or grounded plate attracts them. Thus,
the smoke particles are collected on the negative plates. The ac-
tion is efficient, safe and simple.
ISOMETRIC VIEW
Wash Cycle
All Gaylord ClearAirTM units include, as standard equipment,
an internal washdown system and control cabinet which when
activated washes the unit with hot detergent injected water
to remove the daily accumulation of smoke and grease particles. The washdown system and contols are interfaced with
the Gaylord Water Wash Ventilator. There are two possible
arrangements of controls for the operation of the Ventilator
and the ClearAirTM Unit as illustrated on page 9. In the first
arrangement the Control Cabinet in the kitchen serves both
the Ventilator and the ClearAirTM Unit. The hot water solenoid
valves and detergent pump and container for both the Ventilator and ClearAirTM Unit are located in this cabinet.In the second arrangement there is a Control Cabinet for the ventilator
electrically interfaced with a Sub Panel that serves the
ClearAirTM Unit. The hot water solenoid valves and detergent
pump for the ClearAirTM Unit are housed in the Sub Panel
and the detergent container is located below or next to thepanel. The detergent pump and container for the Ventilator areboth housed in the main Control Cabinet located in the kitchen.In both arrangements the Exhaust Fan, ESP, Wash Cyclesand Fire Cycle Functions are controlled by the Ventilator Con-trol Cabinet. The difference between the two is the location ofthe plumbing components.
Fire Cycle
In the event of a fire, a 250o F. thermostat, mounted in the
airstream, will activate shutting off the exhaust fan and ESP
cells, and turning on the water sprays within the ClearAir
TM
Unit. The fire cycle of the water wash ventilator will also activate at this time. The water will run continually until the thermostat cools below 250o F, and then run for another 2 minutes. At the conclusion of this cool down cycle the exhaust
fan may be started by pushing "Start Fan".

RSPC-ESP FIRE MODE
INTERNAL FIRE MODE
Automatic internal fire protection is accomplished by the
action of the thermostat(s), which is located in the filter section of the RSPC-ESP. When the temperature of the conveying airstream, which must pass over the thermostats,
reaches 250°F, the system is activated, and the following
occurs:
1. The damper begins closing back to the fire position, on
a Gaylord CG3 ventilator, if so equipped, position 3 as
shown in Fig.4—stopping the combustion-supporting,
natural draft through the ventilator and creating a fire
barrier to contain the fire in the kitchen.
2. The exhaust fan is shut off. The supply fan is also shut
off.
3. Fire-smothering water spray is released into the interior
of the RSPC-ESP through the spray nozzles.
4. The digital display reads "Fire In Hood, Fan Off, Wash
On" for approximately 5 seconds.
5. Then the digital display reads "Fire In Hood, Damper
Closing" for approximately 5 seconds.
6. Then the digital display reads "Fire In Hood, Notify Fire
Department". This display stays on until the thermostat
cools down below 250°F.
7. A red light on the Command Center illuminates.
8. If the Command Center is intertied with a building alarm
or monitoring system, a fire signal would be sent to that
system.
9. Upon cooling of the thermostat below 250oF, the Cool
Down Cycle starts. The water continues to spray during
the Cool Down Cycle (2 minutes). The damper moves to
the exhaust position, on a Gaylord CG3 Ventilator , if so
equipped.
10.While in the cool down cycle the digital display reads
"Cool Down Cycle, xxx sec. to end". xxx is the countdown in seconds until the wash turns off.
11.At the end of the cool down cycle the water turns off and
the digital display reads "Fan Off 12:00 (actual time),
Start Fan>F1". The damper closes to the wash position
in a Gaylord CG3 Ventilator, if so equipped.
NOTE: The water may be shut off prior to the end of the 2minute cool down cycle by pushing the “Exit” button on theC-6000 Command Center. After the water has shut off, thedamper remains in the wash position on a Gaylord CG3 Ven-tilator, if so equipped, until the “Start Fan” button is pushed.
CAUTION:
In case of severe fire the thermostats located in the filter
section will activate. As a precautionary measure, it is rec-
ommended that the thermostats be replaced.

EXTERNAL FIRE MODE
An External Fire Mode is activated by the Pollution Control
Units or Ventilator’s Fire Suppression (Duct, Plenum, Surface/Appliance) system’s microswitch or contacts and/or an
optional break glass fire switch (see Figure 5). T erminals 4
& FS are used for the External Fire Mode, refer to wiring
diagram for details. The break glass fire switch, if used,
would normally be located at the exit of the kitchen. When
the External Fire Mode is activated, the following occurs:
1. The Exhaust Fan comes on immediately if it was off to
help remove smoke, heat, etc.
2. The Supply Fan shuts off immediately.
3. The digital display reads “Ext.FireActive” and alternates
between “Reset FireSwitch” and “Fan On, Wash On”.
4. A red light on the Command Center flashes.
5. After a 60-second delay, a fire smothering water spray
is released into the interior of the RSPC-ESP and the
Gaylord CG3 ventilators, if so equipped, through the spray
nozzles.The 60-second delay allows the RSPC-ESP's
and ventilator’s fire suppression system time to put out
the fire, before starting the water spray.
If the fire intensifies and the thermostat reaches 250°F, the
fire damper would then close on a Gaylord CG3 Ventilator, if
so equipped, and the exhaust fan would shut off. See Inter-
nal Fire Mode.
To resume normal operations, open the fire switch and flip the
toggle switch to the position marked “normal”. Replace the
glass rod and close the cover. Push either the “Start Fan”
or “Start Wash” button.
Summary of Both Fire Modes at the Same Time
1.Internal Fire Mode (until thermostat temperature
drops below 250°F)
2.Cool Down Cycle (for 2 minutes)
3.External Fire Mode (until the External Fire Switch is
reset)
TESTING INTERNAL FIRE MODE
The internal fire protection system may be tested periodically by pushing and holding for 20 seconds, the “Fire TestSwitch” located inside the electrical compartment of thecontrol cabinet. Pushing this switch duplicates thermostatic
action.
CAUTION: Before pushing the “Fire Test Switch”,
check to see if the internal fire protection system is tied to
the building alarm system.

SURFACE FIRE PROTECTION
The National Fire Protection Association, NFPA-96 document requires fire extinguishing equipment over all grease
producing cooking equipment such as griddles, ranges, fryers, broilers, and woks. In addition, the system must protect
the interior of the ventilator and the exhaust duct.
The most common fire system is a wet chemical type. In the
event of a fire this system would normally be activated and
discharged prior to the ventilator’s internal fire protection. If
the fire is unusually severe or the surface fire protection system malfunctions, the ventilator’s internal fire protection system would activate, thus providing a second level of defense.
These systems may be intertied with the ventilator control
cabinet to activate the External Fire Mode.

INTERNAL & EXTERNAL FIRE MODES AT THE SAME TIME
It is possible that both the Internal and External Fire modes
can be activated at the same time. If this occurs, the Internal
Fire Mode will override the External Fire mode until the
thermostat(s) cool below 250°F. At this point the Cool Down
Cycle will start counting down for 2 minutes. After the Cool
Down Cycle, the External Fire mode will start.
Special Note: If the control is in the Cool Down Cycle when
the External Fire mode is activated, the Cool Down Cycle
will finish counting down for 2 minutes, before switching to
the External Fire Mode.

Starting the Exhaust Fan
TM
To start the exhaust fan and ClearAir
Unit push the “StartFan” button on the Command Center. If the Command Center
is programmed to start the fan automatically, then the start
button does not need to be pushed. It is important to start the
exhaust fan before turning on the cooking equipment.
When the exhaust fan is activated the following occurs:
1.The damper on Gaylord's CG3 Ventilator begins opening to
the exhaust position. (if applicable)
2.A green light on the Command Center illuminates.
3.The supply fan comes on.
4.The digital display reads "Starting Fan & Damper Open-
ing" for approximately 5 seconds. Then the digital display
reads "Starting Fan, xx Seconds to Fan On". xx is the
coundown in seconds until the exhaust fan comes on.
5. After the damper fully opens (elapsed time approximately
TM
45 seconds) the ClearAir
Unit exhaust fan starts.
6.The digital display then reads "Fan On 12:00" (current
time) and "Start Wash> F2".
7. The cell status light(s) will come on indicating that the
ESP cells are operating.
Stopping the Exhaust Fan and Starting the Wash Cycle
CAUTION: The cooking equipment must be shut off prior
to shutting off the exhaust fan. Failure to do this will cause
excessive heat buildup and could cause the surface fire
protection system to discharge.
To start the wash cycle push the “Start Wash” button on the
Command Center. If the Command Center is programmed to start
the wash automatically, then the start button does not need to be
pushed. When the wash cycle is activated the following occurs:
1.The exhaust and supply fans shut off.
2. The ESP cells shut off.
3.The damper begins closing forward to the wash position.
This action takes approximately 45 seconds.
4.The digital display reads "Starting Wash, Damper Closing"
for approximately 45 seconds, then the digital display reads
"Starting Wash, Wash On in xx seconds". xx is the countdown in seconds to until the wash starts.
5.After the damper in the ventilator closes to the wash position,
the hot detergent injected water sprays come on to wash
away the grease collected during the day's operation. The wash
cycle stays on for the length of time programmed in the Command Center. The length of the wash cycle may be set between
3 and 9 minutes.Typical settings for the CG3 Ventilator are 3
minutes for light-duty equipment, 5 minutes for medium-duty
equipment and 9 minutes for heavy-duty equipment. The typical
TM
setting for the ClearAir
RSPC-ESP unit is 5 minutes. Refer
to page 20 for details on setting the length of the wash.
6.During a Ventilator wash, the digital display reads "Hood
Wash, Wash #1 xxx seconds." xxx is the countdown in
seconds until this portion of the wash is completed.
7.During an ESP wash, the digital display reads:"ESP Wash 1, Wash #2 xxx seconds"
"Hot Water Heating, Wash #2 xxx seconds"
"ESP Wash 2, Wash #2 xxx seconds."
"Hot Water Heating, Wash #2 xxx seconds""ESP Rinse, Wash #2 xxx seconds"xxx is the countdown in seconds until this portion of thewash is completed.
8.The digital display now reads "Fan Off 12:00" (current time)and Start Fan>F1.
After the wash cycle is completed, wipe the exposed front
surface of the damper at the air inlet slot, as well as other
exposed exterior surfaces.
In very heavy cooking operations it may be necessary to
wash the equipment more than once a day. This can be
done manually by pushing the “Start Wash” button.
NOTE: For proper operation of the wash system there mustbe adequate water pressure and temperature.There is a pressure/temperature gauge inside the control cabinet.
Water Pressure60 psi min. - 80 psi max.
Water temperature 160°F min. - 180°F max.
NOTE: Some control cabinets are equipped with a low de-tergent switch. If so equipped, the green light will flash if the
detergent tank is empty or if the detergent pump is malfunctioning and detergent is not pumping. The digital display reads
"Low Detergent" and the text alternates from "Fill Tank" and
"Check Pump". If the detergent tank is filled with water the
detergent switch will activate as if there is no detergent.
NOTE: The wash system is designed to remove daily accumulations of grease within the equipment. If the equipment
is not washed a minimum of once during a cooking day, a
grease buildup could accumulate which the wash system
cannot remove. If this occurs, it is recommended that the
equipment be put through several wash cycles by pushing
the “Start Wash” button on the Command Center. If this
does not remove the grease, it will be necessary to remove
the grease manually by using a scraping tool, such as a
putty knife, or retain the services of a commercial hood cleaning service to steam clean or pressure wash the system.
WARNING: Some commercial hood cleaning services blow a fire
retardant chemical into hood and duct systems. Fire retardant chemicals should never be applied to any portion of The Gaylord Ventilator or ESP unit. If retardant is applied, it must be removed.
