INTRODUCTION

This Electronic Air Cleaner is a two-stage electrostatic precipitator. The air cleaner is designed to
remove airborne particulates, including dust, dirt, smoke, pollen, virus, spores, bacteria, and
mold from indoor air.

Air movement through the unit isprovided by the heating, air conditioning or ventilating system
blower. As dirty air enters the air cleaner, the air passes through Metal Mesh Pre-filters_ The Pre-
filters prevent lint, pet hair and other large particulates from entering the air cleaner, it is
important that these filters be in place to prevent excessive dirt loading of the air cleaner
Ionizing-Collecting Cells° These filters extend the time interval between scheduled maintenance
of the air cleaner, which allows the Ionizing-Collecting Cells to provide clean air for a longer
period between washings_

The pre-filtered air then passes through a two-stage Electronic Air Cleaner. In the first stage, alf
airborne particulate, even submicron size, are electronically charged (positive) as they pass
through the ionizer sectiom The ionizer field is a result of a corona discharge emanating from

the fine, tightly strung wires suspended between two adjacent flat piates, in the second stage,

the charged particulate passes through an intense electrical field established between
alternately charged and grounded parallel collector plates. Here, the charged (positive)
particulate is attracted to the ground (negative) plates and removed from the air stream.

I

Cabinet

Mounts to existing ductwork; houses the Ionizing-Collecting Cells and Pre-fitters.

Ionizing-Collecting Cells

Collect the dust, dirt and other particulates in the air. They contain the ionizing and collecting
sections_ The cells must be installed with the ionizing wires on the air intake side. A spring
contact is located on the top of each cell and must be in the position to make contact with the
contact board assemblies on the bottom of the Power Tray Assembly.

Pre-filters

Trap large particulates before they enter the Ionizing-Collecting Cell

Power Tray Assembly
Contains the indicating lights, solid-state power supply, contact boards and electrical controls

including the ON/OFF switch and safety interlock switch. A power cord at the rear of the 120 volt
Power Tray allows the unit to be connected to a standard 120 volt outlet° A wiring compartment
isprovided on all models at the rear of the Power Tray allowing the option to permanently wire

the unit directly to the HVAC System Control°
Air Flow Sensor (AFS)

Controls the operation of the unit by sensing the movement
of air within the duct. This helps to reduce power usage,

THERMISTOff

\,

AIR FLOWSENSOR

The AFS is designed to provide an efficient and reliable

method of controlling the operation of the air cleaner when
the installer is unable to wire the unit directly into the HVAC
System Blower Control Circuit. The AFS utilizes a thermistor,

which when electrically powered, heats up to approximately

130° RThe AFS stabilizes at this temperature and while the
HVAC System Blower is in operation, air flows through the ductwork, creating a vacuum effect
that pulls cooler air over the hot surface of the thermistor. This air movement cools down the

thermistor which allows the AFS to register that the HVAC System blower is moving air and the

Electronic Air Cleaner must be powered to provide air cleaning
Air Cleaner Model Identification

The model number and part number for your Electronic Air Cleaner can be found on the data
label located on the inside of the Front Panel Assembly°

J

Regular Dusting and "White Dust"

Your new Electronic Air Cleaner will efficiently clean and filter your household air° It will not
eliminate the need for regular dusting of your furniture and belongings_ Duct-mounted air
cleaners can only clean air that reaches the air cleaner. Therefore, if the particulates are not

being carried to the air cleaner in the air stream, the air cleaner cannot remove them from

your home,
Occasionally a "white dust" may be noticed in bedrooms or newly furnished rooms. This is

mainly composed of lint which, because it is heavier than other particulates, settles before it

reaches your unit. This "white dust" is not mixed with airborne dirt particles, therefore, it is
clean and has no staining or soiling properties. Running the furnace blower continuously, day
and night, will help reduce this from occurring_

Ozone

Under normal operating conditions, all Electronic Air Cleaners produce minute quantities of
ozone as an incidental by-product. In fact, all electronic products, such as televisions, cordless
telephones and refrigerators, produce some amount of ozone° The average homeowner can
detect the smell of ozone concentrations as low as 25 to 100 ppb (parts per billion)° The
design of this unit has been tested and ozone production is approximately half of the
published permissible limits established by the Environmental Protection Agency. These limits
recommend that the concentration of indoor ozone not exceed 50 ppb_ Ozone is not harmful

in these concentrations. In fact, the ozone level in major cities can sometimes reach as high
as 100 ppb on a summer day_The addition of optional charcoal after-filters can help reduce
the smell of ozone generated by the air cleaner.

Normally, a new unit will produce more ozone than one that has been in operation for several
weeks_ This is due to sharp corners or manufacturing burrs on the ]onizing_Collecting Cell

Plates and is normal, As the Electronic Air Cleaner arcs and zaps, the voltage is vaporizing
these areas and tends to round them off_ This is part of the breaking-in period and the issue

is self-correcting, Also, high-altitude locations can be more susceptible to noticing the
presence of ozone,

An ionizing-Collecting Cell that has been damaged or bent (the designed spacing between
electrically<harged and ground components has been decreased) may also produce an

abnormal amount of ozone.

HighAltitudeOperation
Becausethe air is less dense at higher altitudes,

there is a possibility of nuisance arcing in the

Electronic Air Cleaner, The homeowner can quickly
and easily correct this conditiom

1_ Make sure the HVAC System Blower is not

operating, the ONIOFF switch is in OFF position
and the circuit breaker is turned OFF or input

power cord isdisconnected°
2_ Remove the Front Panel Assembly,
3_ Remove the cover from the Power Tray

Assembly by removing the two screws on top of

unit. (The entire Power Tray Assembly may be

removed from the cabinet by removing two

screws from inside the cabinet_)

4_

5.

Locate the jumper terminal°

With a pair of needle nose pliers, carefully

relocate the jumper settings from HIGH to MED.

Ensure that the jumper is firmly seated in the

terminal°

6, Replace the Power Tray Cover and secure it with

two screws°

7o Replace the Front Panel Assembly, turn circuit

breaker ON, reconnect input power cord and

turn ONtOFF switch ON,

This procedure will slightly reduce the output
voltage, minimize arcing and reduce ozone

production° If the condition does not improve,
repeat the above procedure and move the jumper
setting from MED (M) to LOW (L).

This unit is produced at the factory with the jumpers

set in the HIGH (H) position. However, the output

voltage may be lowered in any situation where the

unit is arcing excessively or there is excessive ozone,

WASHINGIONIZING-COLLECTING CELLSAND PRE-FILTERS

Regu{ar washing of the Ionizing+Collecting Cells is necessary to ensure proper performance,

A thorough washing once every two months will be adequate for most installations, More
frequent washing (once a month) may be necessary with some installations (new home for
example) where there is new carpeting, plaster dust or excessive cigarette smoke.

To Remove the ionizing-Collecting Cells and Pre+filters from the Air Cleaner:

1, Turn air cleaner ON/OFF switch to OFF position_ Wait 15 seconds+Remove Front Panel Assembly+

2. Carefully remove the fonizing+Coliecting CeiL(s)and Pre-filter(s) and set aside in a safe place_
3+Do not drop the Ionizing-Collecting Ce!loThis can cause damage to the cell plates or ionizing

wires which results in excessive arcing and poor performance.

To Wash Ionizing-Collecting Cells and Pre-filters:

We suggest you follow the instructions below to properly and thoroughly clean your

Ionizing-Collecting Cells.

1, Place enough hot water in a utility tub to cover the first cell+ Dissolve 2+4 oz, of granulated

automatic dishwasher detergent (NOT laundry detergent) in the water=,

2_ Allow the cell to soak for 30 minutes, Agitate it up and down in the solution until it appears

clean and remove_

3_

4+
5,

+

Repeat with second cell (if applicable),
Agitate the Pre-filters up and down in the solution until they appear clean.
With a hose, rinse the ionizing-Collecting Cells and Pre-filters, The hose should be held

about 10" from the cell plates and at a slight angle for maximum cleaning results, Be careful

not to spray the ionizing wires directly with the hose as the water pressure can cause the
wire(s) to stretch and break, The cell frame should be thoroughly rinsed along the edges to
dislodge any trapped lint or dirt+ Carefully wipe a damp cloth or sandpaper (not emery cloth)

along the ionizing wires,

Stand Ionizing-Collecting Cells and Pre-filters in upright position and allow to dry two hours_
You may experience a slight discoloration of the a[uminum collector cell plates after
washing_ This is a normal chemical reaction between the aluminum and detergent and will

not harm your unit or affect its performance+

To Replace Cells in the Air Cleaner;

1+ Replace Pre+filter and Ionizing-Collecting Cells in cabinet. Check that airflow arrow on Cells

point in same direction as air flows through the duct° (If you have to force the ceil past the

positioning screw in the cabinet bottom, the cell is probably in the incorrect position.)

2+ Replace Front Panel Assembly (engage tabs on lower edge of door into slots in cabinet),

Carefully close the Panel

3+ Turn air cleaner ON/OFF switch to ON position_

REPLACING THE IONIZING WIRES

Instances of the Ionizing Wires breaking are minimal due to the constant tension design and

fixed location of the lonizing Wire supports. When an Ionizing Wire breaks, the efficiency of the

Electronic Air Cleaner will decrease slightty_ However, the unit will continue to operate with a
broken Ionizing Wire as long as the broken wire has not caused a short in the secondary circuit
of the unit_ Remove all loose and broken wires as soon as they are identified.

We recommend contacting a qualified HVAC contractor for replacement parts and/or servicing.

ionizing Wires are supplied in a coiled spring configuration, with a clinch nut on each end of the
wire. Replacement requires a pair of needle nose pliers° Exercise caution in removing any broken
wires in the Ionizing-Collecting Cell. The removal of broken wires will prevent accidental
shorting of the cell and reduce the need for further maintenance.

Use the following procedure when replacing an Ionizing Wire:

1o Turn Air Cleaner ON/OFF switch to OFF position,, Wait 15 seconds° Remove the Front Panel

Assembly and remove the Ionizing-Collecting Cells from the unit.

2. Carefully remove all remains of the broken wire from the cello
3_ Grip the new wire at each end with your thumb and index finger, While stretching the wire

to approximately 6", allow one end of the wire to uncoil between your thumb and index
finger_

4. Place one end of the wire in the slot of the stainless steel wire support located on the

Ionizing-Collecting Cell asviewed from the front of the cell. This support ispartially covered
by the cel! brace in front of the support°

5, Grip the other end of the tonizing Wire with needle nose pliers and insert the terminated

end of the wire into the slot in the wire support on the opposite end of the lonizing-
Collecting Cell,

6. The wire should have sufficient tension to be self supporting and remain suspended
between the slots in the wire supports.

CLEANING THE AIR FLOW SENSOR
If the air cleaner is installed in a location that is dusty and dirty, the sensor (thermistor) on the

AFS can become coated with dirt and lint. This coating can insulate the AF5 and keep it from

operating properly, To clean the thermistor, turn the unit OFF, dip a cotton swab in rubbing
alcohol and carefully insert into the 3/16" diameter hole located on the front right hand side of

the Power Tray Assembly (when facing the unit). Carefully twirl the cotton swab between your

fingers, making sure the tip is lightly in contact with the gray disc (thermistor), cleaning the
insulating coating from the thermistor,

Why isn't my Electronic Air Cleaner cleaning my air?
The air cleaner is most likely working just like it was designed, However, many

factors can affect the performance of the unit_ Are air return registers located in
the ceiling? If so, it will be difficult for the air flow to carry heavier particulates to
the air cleaner. If the dirt does not get to the air cleaner, it cannot be removed
from the air. Are both the Red and Green indicating lights illuminated? If not, the

unit may be in need of servicing.
It still isn't cleaning my air the way 1want it to, What can 1do?
It is recommended that you operate the HVAC system continuously so that the air

movement will carry the dirt to the air cleaner where it can be collected.

Unfortunately, there will always be some dirt that isleft behind on the appliances,
furniture, etc. Regular dusting is recommended to stir up these pockets of dust so
that they can enter the air stream and be removed by the Electronic Air Cleaner.

When t turn on my Electronic Air Cleaner, the lights come on for a couple of
seconds and then turn off. The air cleaner isn't working!

The air cleaner is operating properly as long as both the Red and Green indicating

lights are illuminated. Try turning the HVAC blower ON and then turning the

Electronic Air Cleaner ON_This should solve the problem
What is the zapping noise I am hearing from my unit? Should I be concerned?
The zapping or popping noise that you are hearing isthe sound of larger particles

being "vaporized" by the Ionizing-Collecting Cel!oThis is normal and is no cause
for alarm_ As your HVAC system blower moves the air through the ductwork and
allows the Electronic Air Cleaner to clean the air, the noise will diminish, However,
there will always be instances when larger particles enter the Ionizing-Collecting
Cell, and are "vaporized",

Should 1hear this zapping noise all the time?
All Electronic Air Cleaners will occasionally zap or pop as larger particles pass

through the lonizing_Colfecting Ceils° However, if the sound is constant or is
repetitive in nature, then a large particle may have become lodged in the lonizing_
Collecting cell and may require removal by cleaning, If cleaning the Ionizing-
Collecting Cell does not stop the noise and/or there are no large particles trapped
in the ionizing-Collecting Cell, then the cause could be a broken/loose ionizing
wire, bent collector plate or other mechanical fault.

What if I no longer hear any popping or zapping noises coming from my unit? Is

it still cleaning the air?

tf the zapping noises stop and the air cleaner is not in need of servicing, then one
of two situations has occurred_ First, the Electronic Air Cleaner has successfully
removed all larger particles from the air and is cleaning microscopic particles
which do not cause the zapping noises° Second, the HVAC system blower is not
operating and air is not flowing through the ductwork_ The Electronic Air Cleaner
cannot remove particles if the air stream is not moving.

I lost power to my home during a storm, Should 1worry about the Electronic Air
Cleaner ?

The most common problem associated with power outages is the Electronic Air
Cleaner will not turn on properly after power is restored_ If the Green INPUT
POWER indicating light is illuminated, and the Red CELL ENERGIZED indicating
light is illuminated while the HVAC system blower is operating, the unit is
operating properly_, To reset the Electronic Air Cleaner, turn the HVAC system
blower OFF,turn air cleaner OFF,wait one minute, turn air cleaner ON, and then
turn HVAC system blower ON_If the Red and Green lights do NOT come on while
the HVAC system blower is in operation, after a storm, the power supply in the

Electronic Air Cleaner may be short circuited. Contact your local HVAC contractor

for further assistance.

My installer told me to keep my HVAC system blower running all the time, but I

don't want to increase my power bilto What should I do?

It is recommended that you keep your HVAC system blower operating all the time
to achieve the maximum air cleaning efficiency of the Electronic Air C]eanero This
will allow the Electronic Air Cleaner to do what it is designed to do, which is clean
the air_ Remember that if the air does not reach the air cleaner, it cannot be

cleaned. On average, your Electronic Air Cleaner will use the same amount of

electricity as a 55W light bulb_ The energy usage of the HVAC system blower will

depend on the age and size of your system, energy costs in your regional location

and other variables.
The best solution is to operate the HVAC system blower in a continuous mode for

a month or two, estimate annual energy costs, and base your final decision with
what you feel most comfortable.

Application

Theaircleaner is used in forced air heating, cooling and ventilating

systems, tt should be installed in the system such that all the system air
is circulated through the air cleanerr The air cleaner will only remove
the airborne contaminants delivered to it; maximum performance is
obtained with the system blower set for continuous operation°

Installation Requirements

• The best location for the air cleaner is in the return air duct next to
the blower compartment. In this location, the blower motor and

cooling coils will be kept clean.

e DO NOT INSTALL THE AIR CLEANERIN THE DISCHARGE AIR DUCT

• Before installing the air cleaner, consider the application and type of

HVAC system present°

= Refer to the Typical Mounting Positions section for the most

common configurations°

= Refer to the Transitions section if a transition is required between

the duct work and the air cleaner.

. The unit must be readily accessible for periodic inspection and

cleaning of the Pro-filters and Ionizing-Collecting Cells to maintain
maximum efficiency and trouble free operation_

Air Conditioning
The air cleaner should be installed upstream of the cooling coil to

keep the coil clean and reduce air conditioning coil maintenance° A
clean coil will reduce utility costs by maintaining the coil's efficiency° if
the air cleaner is downstream of the cooling coil, condensation will
form on the cooled collector plates when the air conditioner cycles_
This will allow water droplets to form on the collector plates and
cause nuisance arcing in the air cleaner, Arcing will reduce air cleaner
efficiency and reduce the life of the high voltage power supply.

Evaporative Humidifiers
An evaporative type humidifier can be mounted either upstream or

downstream of the air cleaner, depending upon the desired
humidification capacity.

12

AtomizingHumidifiers

If an atomizing humidifier is mounted upstream
of the air cleaner:

Ir

,

,

Mount the humidifier as far upstream in the
ductwork as possible. A distance of at least

10 feet is recommended to reduce the
possibility of excessive arcing as water

droplets pass through the Electronic Air

Cleaner.

Install a standard disposable furnace filter

between the humidifier and the air cleaner
to trap water droplets and hard water
deposits_

Clean the air cleaner more frequently to

prevent hard water buildup,

If an atomizing humidifier is mounted
downstream of the air cleaner:

No additional considerations required_

Sheet Metal Installation

The Electronic Air Cleaner is adaptable to all new

or existing resident[a! forced air furnace and
cooling systems,

Transitions

If the air duct does not fit the air cleaner cabinet
opening, gradual transitions are recommended

to reduce air turbulence through the air cleaner

and maximize efficiency. Not more than 20 °
(about 4" per running foot) of expansion should

be used on each side of the transition section°
Outdoor Air

When outdoor air is added to the return air duct,

sufficient heat should be added to maintain the
return air temperature at 40°F (4° C) minimum,

Lower temperatures can cause ionizer wire
failure,

Turning Vanes

If the air cleaner is installed adjacent to a 90° duct
elbow, add turning vanes inside the duct to
improve air distribution across the face of the air
cleaner_ Failure to follow this recommendation

can reduce the efficiency of the Electronic Air
Cleaner.

Make sure the HVAC system blower is not operating, the ON/OFF switch is in

position and the circuit breaker isturned OFFor input power cord is disconnected.

Remove the Front Panel Assembly.
Remove the cover from the Power Tray Assembly by removing the two screws on

top of unit.
Locate the AFS, a sinai( circuit board with a small gray disc connected to the board

by two sitver wires (seeAir Flow Sensor (AFS) pgo 2). Carefully bend the thermistor
(small gray disc) wire leads so the thermistor is located in the center of the 3/16"

PRIMARYCIRCUIT WiTH HVAC SYSTEM BLOWER OPERATING

If there is no supply line voltage at the transformer input connections,
correct the fault at the dedicated power source or HVAC system power

source_
If there is supply line voltage at the transformer input connections and

no output voltage (24 volts nominal), the transformer is defective and
must be replaced_

If there is transformer output voltage (24 volts nominal) and no output

voltage from the ON/OFF switch, the outage can be located by checking

operation of the safety interlock switch and the interconnecting wiring

with a Multimeter_ Refer to Circuit Diagram, (pg. 22) to check operation

of the switches.

PRIMARY CIRCUIT WITH HVAC SYSTEM BLOWER NOT OPERATING
Follow these steps to test for proper operation of the Power Supply Board,

ON/OFF Switch, and Safety Interlock Switch.

1. Ensure that the circuit controlling the HVAC system blower is in the OFF
position, and input power to the air cleaner is disconnected,

,

The power supply board has a builtqn internal fuse to protect the 24V
transformer. The fuse can be checked visually by inspection, if the fine
wire inside of the fuse is broken, a fault exists in the 24V circuit. Do NOT

replace this fuse, The entire Power Supply Assembly must be replaced-

The purpose of the fuse in not to protect the power supply board, but to

function as a troubleshooting feature of the product and to protect the

transformer from damage.

If the fuse is NOT blown, check the ON/OFF switch and safety interlock
switch for proper engagement and operation,. This can be completed
using a Multimeter with an OHM scale capable of reading 1.0 ohm°

Remove the fuse, Connect one Multimeter test lead to the test pin hole
(Jg) located directly beside the wire that connects the ON/OFF switch to

the power supply board_ Connect the other Multimeter test lead to the

fuse connection nearest the front panel.

Turn the ON/OFF switch to the ON position and depress the safety

interlock switch. The Multimeter should have the capability of reading
levels as tow as It0 ohm° Multimeter reading of 1.0 ohm or less indicates
correct operation of the ONIOFF switch and the safety interlock switch,

If the Multimeter ohm reading isgreater than 1o0ohm, begin the process
of elimination by moving the Multimeter test lead from the test pin hole
(Jg) to the safety interlock switch terminal with the blue wire lead.
Depress the safety interlock switch, if the reading on the meter is greater

than 1o0 ohm, the safety interlock switch is defective and must be

replaced. If the reading on the meter is less than t.0 ohm, the ON/OFF

switch is defective and must be replaced.

SECONDARY CIRCUIT

iONIZING-COLLECTING CELL

The cells are electrically energized through a contact terminal located at the top
center of each cell, The ionizing wires and alternating collector plates are electrically
charged while the interleaving plates are grounde&

If the space between the charged and grounded plates is bridged with conductive
or semi-conductive material, a short circuit develops. The bridging or short may be
caused by damaged plates, or foreign material lodged between/on the components.
Since the cell should be periodically removed from the unit to wash away collected
dirt, it is susceptible to physical damage. The cell also contains the ionizing wires,
which have been designed, due to their function, with minimal structure support
and are susceptible to breakage_ Short circuit issues related to dirty or damaged

Ionizing-Collecting Cells are readily identified by the lack of illumination of the Red

CELLENERGIZED light and quickly identified and isolated by a simple procedure,
To determine if a short circuit condition exists in one or both Ionizing- Collecting

Cell(s), turn the Electronic Air Cleaner OFF. Remove both Ionizer- Collecting Cells
from the cabinet° Re-position the Front Panel Assembly to the cabinet, turn ON/OFF
switch ON and ensure HVAC system blower is operating,

The Green INPUT POWER light should Uluminate. If the Red CELL ENERGIZED light

illuminates, an electrical short circuit exists in one or both of the Ionizing-Collecting

Cells_Replace the cells, one at a time, to determine which cell has the short circuit,
The Red CELL ENERGIZED light will not illuminate if a short circuit condition is

detected°

Most short circuit troubles in the celt can be visually detected and corrected. Refer
to COMMON TROUBLESHOOTING TECHNIQUES (pg. 9).

SECONDARY CIRCUITPOWER SUPPLY

if the Red CELL ENERGIZED light remains out with the Ionizing_Collecting Cells

removed from the cabinet, the power supply is defective° Specific problems in the
Power Tray Assembly can be isolated by using a Muttimeter and High Voltage
Probe to check the output voltages.

To check the secondary circuit, a high voltage meter isrequired_ See the section
entitled RECOMMENDED SERVICETOOLS (pg. 20), To check for proper operation,

it is imperative that the procedure be followed as outlined below:

1. Make sure the HVAC system is operating, the air cleaner ON/OFF switch is
ON, and air cleaner input voltage is correct (120V, 50-60Hz for 120V units and
240V, 50-60Hz for 240V units).

2. Remove Front Panel Assembly from air cleaner°
3_ Remove Power Tray Assembly Coven

4, Check the high voltage contact board assembly for damage or carbon

tracking.

Replace both Ionizing-Collecting Cells in the air cleaner cabinet

Make test connections from the High Voltage Probe to the Multimeter in
accordance with the probe's instruction manual° The Multimeter should be
set for reading DC voltage at 20 volt full scale°

Attach the High Voltage Probe ground lead to the air cleaner cabinet° While
depressing the safety interlock switch lever, touch the ionizer wire support

with end of the High Voltage Probe. The meter reading should be 6.2 kVDC
+ .2 kVDC

If no voltage is measured, remove the first Ionizing-Collecting cell and check
the second cell by repeating step #7,, The meter should read 6.2 kVDC + ,2

kVDC,

If proper voltage is measured, the first cell is shorted, Refer to COMMON
TROUBLESHOOTING TECHNIQUES (pg, 9),

If no voltage is present, remove the second cello
Install cell number one and measure voltage as
described in step #7. tf voltage is present, the
second cell, which is now out of the cabinet, is
shorted° Refer to COMMON TROUBLESHOOTING
TECHNIQUES (pg. 9).

If no voltage is present, remove both Ionizing-
Collecting Cells and measure the power supply
output. While depressing the safety interlock
switch lever, touch the end of the high voltage
probe to either the front or rear contact board
assembly, The meter should read 6.2 KVDC or
higher°

If no voltage is present, check the transformer. Set
the Multimeter for reading AC voltage at 200 volt

full scale and attach meter test leads to the
junction of the transformer secondary leads and

the circuit board_ The meter should read 24 volts
+/- 4 volts,

If there is no voltage from the transformer,

replace the transformer and power supply board.
