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.

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.

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.

Grease Grabber™ H2O System Function

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 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 GGH2O

Page 4

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.

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.

Model GGH2O

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 Greenheck. All plumbing and wiring must conform to plumbing and electrical codes. Duct collars are factory mounted unless specified otherwise.

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

The recirculation pump is shipped loose with the hood. See pages 16 for installation details.

Graphic Keypad

The graphic keypad is the interface between the control functions of the GGH2O 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.

Proﬁle of Hood

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, the hood will be damaged during the installation process.

Proﬁle of Hood

Carefully rotate the hood as shown.

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.

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.

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.

CAUTION

To ensure proper structural support, all hanger brackets must be used for hanging the hood.

Detergent Requirements

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.

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.

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.

NOTE

G-510 is manufactured by 2010 Products, Inc., Food Service Division, Salem, Oregon 97303. For details and ordering information, call 800-286-2010.

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

9:00 pm ON / 11:00 pm OFF

c. Set the OFF time for one minute after the ON

time.

Reviewing Events Programmed

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™ H on page 27 for detailed instructions on start-up operations.

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.

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 =

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)

Hood Length 96 inches

Test Location (off left; in inches)

Velocity Reading (fpm) 175 210 250 190 160

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

of Test Locations

48 to 72

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

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.

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.

Approved wash detergent

Formula G-510 from 2010 Products, Inc. Phone: 800-286-2010 (Not provided by Greenheck).

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.
