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.

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 Greenheck Fan Corporation.

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.

Model GGH2O

®

Greenheck GGH2O 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 pre-

programmed control sequence by pressing the CLEAN

HOOD button or automatically engaged to run at the

same time each day through a programmable timer.

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.

NOTE

The wash sequence of the hood is not designed for

fire suppression and will not engage in the event of

a fire.

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).

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.

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.

With Water: 48 inch width x 120 inch length

= 488 lbs. + (6 ft. x 67 lb/ft)

= 488 lbs. + 402 lbs.

= 890 lbs.

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.

must be set to AUTO mode.

• AUTO runs all events automatically according to the

schedule you have set. The word AUTO appears in

the display.

• RND (random) runs all events in a RANDOM mode.

This is a security feature in which ON and OFF

times randomly differ +/- 15 minutes from the

programmed times, creating a more “lived-in” look.

The word RND appears on the display.

NOTE

Do NOT set this timer to RND mode. It will not wash

at the exact time you programmed.

• MANUAL turns ON and OFF only when the user

presses the ON or OFF button. The display is blank,

showing neither RND or AUTO.

Overriding Timer Settings

The ON or OFF buttons override the current

programmed events. To override the current program

(either ON or OFF), press the ON or OFF button.

Initial System Start-Up

1. Check electrical power (see wiring diagram)

• Correct supply voltage

• Proper connections to fire

suppression system

2. Check to make sure the

disconnect switch on the

electrical control cabinet is

switched to the “ON” position.

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.

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.

Daily Operation of the GGH2O Hood

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.

Airflow Testing Procedure

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)

Average Velocity (FPM) =

(175 + 210 + 250 + 190 + 160)  5 = 197 FPM

Hood Exhaust Rate (CFM) =

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

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.

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

Average Velocity = Sum of Velocity Readings

Number of Readings

Hood Length 48 to 72

inches

72 to 120

inches

120 to 192

inches

Minimum Number

of Test Locations 357

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.

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.

Hood Length 96 inches

Maintenance

Capture Tank

The interior surfaces of the hood capture tank should

be wiped down weekly.

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.

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.

If any filter appears damaged, consult factory for

replacement.

Floats

The floats need to be

inspected two weeks after

start-up and then once a

month thereafter.

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.

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.

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.

Low Float

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

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.
