Cleaning Cycle
Manual Engagement
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).
Fire Mode
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.
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.
NOTE
The wash sequence of the hood is not designed for
fire suppression and will not engage in the event of
a fire.
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.

Base weight is based on 48 inches (121.92 cm) hood
length. For each additional foot of hood in length, add
55 lb/ft (24.95 kg/m) in weight of hood and 67 lb/ft
(30.39 kg/m) in weight of hood filled with water.
Profile of Hood
Example of a 10 foot hood:
Dry:
48 inch width x 120 inch length
= 440 lbs. + (6 ft. x 55 lb/ft)
= 440 lbs. + 330 lbs.
= 770 lbs.
Carefully rotate
the hood as
shown.
With Water: 48 inch width x 120 inch length
= 488 lbs. + (6 ft. x 67 lb/ft)
= 488 lbs. + 402 lbs.
= 890 lbs.
Profile of Hood
DANGER
The maximum weight (weight with water) should be
used for the maximum weight of the hood to ensure
the ceiling structure can support the weight of the
hood when filled with water.
Carefully slide the
hood onto the lifting
skid. The lifting skid
should be used to lift
the hood into its final
position. If the lifting
skid is not used,

PLC. The fan starter is not provided with the wash
control station.
The detergent brand Formula G-510 (by 2010
Products, Inc.) is recommended by Greenheck 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.
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.
Preventative Maintenance
The following practices will prolong the life of the
detergent pump:
• 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
and ordering information, call 800-286-2010.

Daily Operation of the GGH2O Hood
Pressing the FAN ON/OFF button will start/stop the
exhaust and supply fans if interlocked.
Initial System Start-Up
1. Check electrical power (see wiring diagram)
• Correct supply voltage
Pressing the HOOD LIGHTS button will turn on/off the
hood lights.
• Proper connections to fire
suppression system
Initiating the wash cycle:
2. Check to make sure the
disconnect switch on the
electrical control cabinet is
switched to the “ON” position.
The Grease Grabber H O has an automatic timer
2
that can be set to control the wash schedule and
automatically start the cycle. See Timer Programming
on page 18.
3. Prime the recirculation pump. Remove the plug on
top of pump and use a funnel to add water to the
pump. This only needs to be done one time prior to
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.
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™ H O Hood checklist
on page 27 for detailed instructions on start-up
operations.
2
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 H O sequence of operation

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.
Sum of Velocity Readings
Average Velocity
=
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™ H O.

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.
Velocity Reading (fpm) 175 210 250 190 160
Average Velocity (FPM) =
(175 + 210 + 250 + 190 + 160) 5 = 197 FPM

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.
The float can be inspected
by first turning the
Access Panel Door
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.
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.
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.
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.
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.
Safety Float
High Float
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.
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.
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.
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
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.
Hood is not cleaning
If the hood does not seem to be adequately cleaned,
look for the following:
Detergent tank — is it empty or filled with wrong
detergent?
Greenheck Grainger®
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.

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.
