Receiving
Upon receiving the product check to make sure all
items are accounted for by referencing the bill of
lading to ensure all items were received. Inspect
each crate for shipping damage before accepting
delivery. Notify the carrier if any damage is noticed.
The carrier will make notification on the delivery
receipt acknowledging any damage to the product.
All damage should be noted on all the copies of the
bill of lading which is countersigned by the delivering
carrier. A Carrier Inspection Report should be filled out
by the carrier upon arrival and the Traffic Department.
If damaged upon arrival, file claim with carrier. Any
physical damage to the unit after acceptance is not
the responsibility of the manufacturer.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing, report shortages to your local representative
to arrange for obtaining missing parts. Sometimes it
is not possible that all items for the unit be shipped
together due to availability of transportation and truck
space. Confirmation of shipment(s) must be limited to
only items on the bill of lading.
Handling
Units are to be rigged and moved by the lifting
brackets provided or by the skid when a forklift is
used. Location of brackets varies by model and size.
Handle in such a manner as to keep from scratching
or chipping the coating. Damaged finish may reduce
ability of unit to resist corrosion.
Storage
Units are protected against damage during shipment.
If the unit cannot be installed and operated
immediately, precautions need to be taken to prevent
deterioration of the unit during storage. The user
assumes responsibility of the unit and accessories
while in storage. The manufacturer will not be
responsible for damage during storage. These
suggestions are provided solely as a convenience to
the user.
The ideal environment for the storage of units and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of
blowing dust, rain, or snow. Temperatures should
be evenly maintained between 30°F (-1°C) and
110°F (43°C) (wide temperature swings may cause
condensation and “sweating” of metal parts). All
accessories must be stored indoors in a clean, dry
atmosphere.
Remove any accumulations of dirt, water, ice, or snow
and wipe dry before moving to indoor storage. To
avoid “sweating” of metal parts allow cold parts to
reach room temperature. To dry parts and packages
use a portable electric heater to get rid of any
moisture build up. Leave coverings loose to permit air
circulation and to allow for periodic inspection.
2
Model XGH2O
The unit should be stored at least 3½ in. (89 mm) off
the floor on wooden blocks covered with moisture
proof paper or polyethylene sheathing. Aisles between
parts and along all walls should be provided to permit
air circulation and space for inspection.
Inspection and Maintenance during Storage
While in storage, inspect once per month. Keep a
record of inspection and maintenance performed.
If moisture or dirt accumulations are found on parts,
the source should be located and eliminated.
REMOVING FROM STORAGE — As units are removed
from storage to be installed in their final location,
they should be protected and maintained in a similar
fashion, until the equipment goes into operation.
Prior to installing the unit and system components,
inspect the unit assembly to make sure it is in working
order.

Grease Grabber™ H2O System
Function
Accurex XGH2O hoods are designed for three primary
functions:
• Capture and contain the effluent produced by the
cooking process.
• Remove grease and other contaminants from the
airstream with two stages of mechanical filters
(Primary Grease X-Tractor filters and secondary
Grease Grabber filters).
• Wash the filters and other surfaces within the
exhaust plenum to remove contaminants.
NOTE
The wash sequence of the hood is not designed for
fire suppression and will not engage in the event of
a fire.
NOTE
The functions listed above require the control center
to be wired to the exhaust fan(s) and the hood
plumbed.
NOTE
For a complete list of functions, please refer to the
sequence of operations.
Normal Exhaust Operation and
Contaminant Collection
The system’s exhaust fan is manually controlled by
a press-button switch (FAN ON/OFF) on the graphic
keypad (included with hood). The exhaust system
operates until the FAN ON/OFF button is pressed. The
wash cycle can be manually engaged to run on a preprogrammed control sequence by pressing the CLEAN
HOOD button or automatically engaged to run at the
same time each day through a programmable timer.
Model XGH2O
3
Cleaning Cycle
Fire Mode
Manual Engagement
In the event of a fire, the hood exhaust fan(s) will turn
on at full power and the supply fan will turn off (default
setting controlled by others) regardless of current fan
operation. If the hood is in a wash cycle, the hood will
drain and the fans will turn on.
The wash function is triggered by pressing the Clean
Hood button after the exhaust fans are shut down at
the end of each day’s cooking operations (pressing
the Fans On/Off button).
Hot water and detergent will fill the hood reservoir.
The soapy water will then be cycled through the hood
by the attached recirculation pump, cleaning both the
filter banks and the exhaust plenum area on a timed
cycle.
When the cleaning cycle is complete, the water
is purged from the reservoir by the pump and the
reservoir will again fill with clean hot water.
A rinse cycle will then run on a timed cycle and the
water will again be purged by the pump.
When the cycle is complete, the controller runs the
exhaust fans briefly to remove steam and excess
moisture from the exhaust system.
Automatic Engagement
The hood is equipped with an automatic timer. The
timer will automatically initiate the wash sequence
at the programmed time each day. All other washing
functionality will be the same as the manual
engagement sequencing.

Model XGH2O
NOTE
The wash sequence of the hood is not designed for
fire suppression and will not engage in the event of
a fire.
System Components
Hood
The hood is shipped from the factory pre-piped and
ready to install. All wash components within the hood
are complete and ready for connection to hot water,
sanitary sewer drain and the electrical sources. Wiring
from the control panel to the hood (for lights) is by
manufacturer. All plumbing and wiring must conform
to plumbing and electrical codes. Duct collars are
factory mounted unless specified otherwise.
Graphic Keypad
The graphic keypad is the interface between the
control functions of the XGH2O hood and the user.
This keypad is typically mounted on the Grease
Grabber H2O control cabinet, but can also be shipped
loose for remote mounting. The keypad consists
of three main buttons: hood lights, fan on/off and
clean hood. The keypad also has system fault and fill
detergent indicator lights to alert of any fault in the
system or when the detergent tank is low.
NOTE
Filters are shipped loose with the hood and installed
in the field. See page 25 for installation details.
Grease Grabber H2O Control Cabinet
The control cabinet contains all of the water and
electrical components, and connections including
the Programmable Logic Controller (PLC), that
controls the wash sequencing and operations. The
control cabinet also includes the detergent reservoir,
detergent pump, recirculation pump, solenoid valves
and other water piping.
NOTE
he recirculation pump is shipped loose with the
T
hood. See pages 16 for installation details.

Hood Hanging Height
The hood hanging height is critical. Hanging the hood
at the incorrect height may significantly reduce the
ability for the hood to function properly and may be in
violation of codes. The hood hanging height (typically,
78 in. (198.12 cm) above the finished floor) is given on
the UL label located on the inside of the hood on the
end panel. The hood must be hung level to operate
properly.
NOTE
Before hanging the hoods, please verify the hood
marks to make sure the correct hood is hung on the
correct side.
NOTE
The installation of the canopy hoods shall be
in accordance with NFPA 96 (latest edition),
Standard for Ventilation Control & Fire Protection of

Detergent Requirements
The detergent brand Formula G-510 (by 2010
Products, Inc.) is recommended by manufacturer
for use in the wash system. Use Formula G-510 full
strength. This product is biodegradable, non-caustic,
and safe for kitchen staff to use. If G-510 detergent is
not used, the cleanliness of the exhaust plenum and
filters cannot be guaranteed.
Preventative Maintenance
The following practices will prolong the life of the
detergent pump:
Electrical
Electrical Wiring
All wiring must be done according to NEC (National
Electrical Code NFPA #70) and local building codes.
Two sources of power need to be brought into
the electrical control cabinet. A 120 volt, 30 amp
service with 12 gauge wire needs to be connected
to terminals L1 on the disconnect switch and N. A
120 volt, 15 amp service with 14 gauge wire needs to
be brought into the electrical cabinet and connected
to terminal L2 on the disconnect switch and N1.
NOTE
The wash control station will provide a dry contact
for a fan starter so the fans can be controlled by the
PLC. The fan starter is not provided with the wash
control station.
The main recirculating pump needs to be wired after it
is installed in the hood. There are three 12 gauge wires
in flexible conduit wired to the pump. Wiring to the
pump is complete from the factory. The whip from the
pump needs to be wired into the control cabinet.
• Keep detergent tank filled.
•Avoid spilling detergent on the exterior of the
pump.
• Clean the detergent tank at least every six
months.
• Clean the detergent line strainer at least every six
months.
• Check tightness of all fittings periodically.
The detergent pump motor has sealed bearings which
do not require lubrication.
NOTE
G-510 is manufactured by 2010 Products, Inc., Food
Service Division, Salem, Oregon 97303. For details

3. Press the HOUR button until the display shows the
current hour.
4. Press the MIN (minute) button until the display
shows the current minute.
Setting the Programs
1. Press the PROG (program) button once. You will
now set the time in which you want the wash to
start. The number 1 in the lower left hand corner
indicates that you are now programming Event 1.
2. Press the DAY button repeatedly until the display
shows the day(s) when you want the timer to turn
on. The options are:
- Days of the week
MO, TU, WE, TH, FR, SA, SU
- Individual days of the week
MO etc.
- Weekdays only
MO, TU, WE, TH, FR
- Weekends only
SA, SU
3. Press the HOUR and MIN (minute) buttons to set
the time when you want the timer to turn on.
4. Press the PROG (program) button again.
5. Repeat steps 2-4 to set the OFF time for Event 1.
This should be set one minute after the ON time.
6. When programming is complete, press the CLOCK
button to display the current time.
Things you should know about programming events:
• You can repeat the ON and OFF programming
procedures outlined above for up to seven (7)
events as needed.
NOTE
While setting events, the timer may prematurely turn
on the load, if you press the MODE button.
• Three kinds of settings can cause the timer to
work in an unexpected way:
a. Set up events in progressive order of time, for
example:
8:00 pm ON, 9:00 pm ON, 10:00 pm ON
Not 8:00 pm ON, 10:00 pm ON, 9:00 pm ON
b. Do not overlap event times, for example:
8:00 pm ON / 12:00 pm OFF and

initial start-up.
4.Add detergent to the detergent tank in the cabinet.
5.Clean the control cabinet of any debris that may
have entered the cabinet during installation.
6.Close the cabinet doors and press the Fan On/Off
button.
7.Check the exhaust and supply air volumes.
8.Press the Fan On/Off button to turn the fans off.
9.Press the Clean Hood button.
When the hood is filling, check to ensure water is not
leaking through the edges of the access doors. If so,
the inlet water pressure is too high. Slowly close ball
valve located before the inlet solenoid on the hood top
until no water leaks pasT the access doors.
Pressing the FAN ON/OFF button will start/stop the
exhaust and supply fans if interlocked.
Pressing the HOOD LIGHTS button will turn on/off the
hood lights.
Initiating the wash cycle:
The Grease Grabber H2O has an automatic timer
that can be set to control the wash schedule and
automatically start the cycle. See Timer Programming
on page 18.
To initiate the wash cycle manually, press the CLEAN
HOOD button on the keypad. If you press this button
while the fans are running, the system will stop the
fans and then start the wash cycle. When the wash is
completed, the system will automatically reset itself.
If the fans are controlled by a building management
system (BMS), the steps above still apply unless a
special program is requested to bypass having to
initiate the wash cycle by pushing the FAN ON/OFF
and CLEAN HOOD buttons.
Refer to the Grease Grabber™ H2O Hood checklist
on page 27 for detailed instructions on start-up
operations.
After the hood fills with water and starts washing the
primary filters, open water valve slowly until water
mist is felt above equipment. Then slowly close valve
until water mist is no longer felt above equipment.
Once the valve is set it will not need to be moved
again.
Verify the Grease Grabber H2O sequence of operation
(see the diagram of wash sequence on page 20)
during the detergent pump cycle.

Airflow Testing Procedure
After the appropriate number of readings have been
taken from the inlet slot of the hood, an average
reading can be calculated by summing the velocity
readings and dividing the total value by the number of
readings taken.
Average Velocity
=
Sum of Velocity Readings
Number of Readings
Next calculate the total hood airflow volume (CFM) by
using the following equation:
Hood CFM = [(Length of Hood in inches x 4.846) x
(Average inlet slot velocity x 2.47)]  144
NOTE
The constants 4.846 and 2.47 are factory derived for
use with the Grease Grabber™ H2O.
Calculation Example:
Five (5) inlet slot velocity readings (minimum)
Short Ridge Meter Components
For measuring exhaust airflow rates (cubic feet per
minute = CFM), use a short ridge meter to measure
velocities along the inlet slot of the hood. To ensure
accurate data, all appliances should be on. Multiple
locations need to be tested as outlined below to
ensure an accurate reading.

Average Velocity (FPM) =

Hood Exhaust Rate (CFM) =
[(96 x 4.846) x (197 x 2.47)]  144 = 1572 CFM

To take velocity readings along the length of the hood,
the edge of the short ridge meter must start/stop six
(6) inches from the end of the hood. Vertical placement
of the short ridge meter along the inlet is shown.

Maintenance
Capture Tank
Floats
The interior surfaces of the hood capture tank should
be wiped down weekly.
The floats need to be
inspected two weeks after
start-up and then once a
month thereafter.
Filters
The Grease Grabber filters (bead filters) require
visually inspection (not removed from hood) two
weeks after start-up, then once a month thereafter to
make certain the filters are positioned correctly in the
plenum. Positioned correctly means there are no gaps
between the filters.
To inspect the bead filters, remove the fasteners
holding the access doors; each door has five (5)
fasteners. Remove every other door to inspect the
filters.
The float can be inspected
by first turning the
disconnect switch on the
control cabinet to the ‘OFF’
position. Then remove the
large access panel door.
Once the access panel
is removed, you will have
access to the floats.
After inspecting the filters, put the access doors
back on and put the fasteners back in. Be careful not
to over-tighten or cross thread the fasteners when
putting them back in.
The Grease Grabber filters
(bead filters) need to be
removed from the hood
once every three months to
visually inspect and ensure
the filters are structurally
sound.
Remove all the doors
and remove the filters for
inspection. Depending on
the equipment under the
hood, it will probably be
easier to remove the filters
from the right side of each
hood. Slide the other filters
down to the end access
door for removal.
After inspecting the filters,
place them back in the
hood. Be careful to install
the filters with the handles
up and make sure not to
hit the fire detection line
when removing or installing
the filters. Ensure no gaps
are between filters after
installation.
Access Panel Door
Float Installed
Slide each float (Low Float,
High Float and Safety Float)
up the stem to its stop with
your finger and let go. If float
slides freely down the stem
with minimal resistance, the
float is operating as it should.
Put the access panel back
on and turn the disconnect
switch to the ‘ON’ position.
Safety Float
High Float
Low Float
If the float does not slide
freely down the stem, the
stem and floats are dirty
and need to be wiped off with a clean cloth. Cleaning
the stem involves removing all the clips (stops). Slide
floats up and down on the shaft as required to access
and clean the entire length of the shaft. Return floats
to their location and reinstall stops.
Make sure all float stops are securely located in their
grooves and floats are located in their designated
spots.
If for some reason the floats
get taken off the stem, the
stamped circle on the top
side of the float needs to
face up.
If any filter appears damaged, consult factory for
replacement.
NOTE
Be careful when handling the float stops. These are
small clips and can easily be dropped. If you loose
one of these clips, consult factory for a replacement.

Troubleshooting
Replacement Parts
Hood is not cleaning
When ordering parts, please be prepared to provide
us with your cabinet and hood system model
number, and serial number from labels on the hood
and cabinet. See the chart below to identify the
replacement parts needed.
If the hood does not seem to be adequately cleaned,
look for the following:
Detergent tank — is it empty or filled with wrong
detergent?
Detergent pump — is the detergent pump running?
Is there power to the pump? Is the detergent level
low? If the hood plenum area is not sufficiently
cleaning, consult factory for information on
increasing duration of wash cycle and detergent
pump.
Nozzles — are any of them clogged? If so, they can
be removed and cleared using a small wire.
Water temperature — is it at least 140°F.
Hardness of water — test water for hardness level.
It is recommended that soft water be used.
Hood not draining properly — plugged drain.
Ensure all floats have stamped circles facing up.
Water leaks — water leaking through the access
panels when filling. Ensure access panels are securely
in place. If leak persists, partially close inlet water ball
valve (by others) upstream of fill solenoid to reduce
water pressure.
Condensation in the hood — large amounts of
condensation while hood is washing. Hood should
be washed after the hood and equipment is warm,
not hot. The warm equipment helps reduce the
condensation that forms in the hood.
