HOW TO USE THIS MANUAL

Read and save these instructions. This manual is designed to assist qualified field service, operating and maintenance personnel with the installation, operation, and maintenance of Greenheck canopy type kitchen hoods and accessories.

Procedures described in this manual should be followed in the order they appear, with attention to all safety and caution statements.

RECEIVING, HANDLING & STORAGE:

Upon receiving the equipment, check for both obvious and hidden damage. If damage is found, record all necessary information on the bill of lading and file a claim with the final carrier. Check also to be sure that all parts of the shipment, including accessories, are accounted for.

If a kitchen hood must be stored prior to installation, (or for any long period) it must be protected from dirt and moisture. Indoor storage is recommended. For outdoor storage, cover the hood with a tarp to keep it clean, dry, and protected from UV (Ultra Violet) radiation damage.

NOTE: The kitchen hood is shipped with a plastic film attached to the surface. The film is to protect the panels from minor scratches during handling and shipment. This film must be removed prior to assembling the system. When the system is operating, the film will melt and bake on to the surface. Once the film is removed caution should be used in handling the parts.

Improper storage which results in damage to the unit will void the warranty.

NOTE: The functions listed above require the control center to be wired to the exhaust fan and plumbed.

WATERWASH SYSTEM FUNCTIONS:

Greenheck waterwash hoods are designed for three primary functions:

1) Capture and contain the effluent produced by the cooking process.

2) Remove grease and other contaminants from the airstream with a series of extraction baffles.

3) Wash the baffles and other surfaces within the exhaust plenum to remove contaminants.

Normal Exhaust Operation and Contaminant Collection:

The system's exhaust fan is manually controlled by a push-button switch (Start Fan) located on the face of the waterwash control station. The exhaust system operates until the Stop Fan/Start Wash push-button switch is pressed.

Optional Continuous Cold Water Mist:

The optional continuous cold water mist is controlled by the same push-button switch (Start Fan). With this option, all hoods with this option are sprayed continuously when the fan is on. This feature acts as a spark arrestor for solid fuel applications, as per NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. This does not have to be all hoods - can be just the solid fuel hoods.

Cleaning Cycle:

A factory programmed controller triggers the waterwash function when the exhaust fans are shut down at the end of each day’s cooking operations. A pressurized spray of hot water and detergent cleans the hood in a timed cycle. When the cleaning cycle is complete, the controller runs the exhaust fans briefly to remove steam from the exhaust system. The controller then automatically resets itself. If the kitchen is closed for a day, the wash cycle will skip as long as the start fan button has not been pushed

For multiple hoods totalling over 20 ft. 0 in. in length, systems are designed to wash each hood or group of hoods sequentially. (Hoods totalling up to 20 ft.0 in. in length can be washed as a single unit.)

April 2005

Fire Mode (Optional):

The waterwash system also provides water spray for the exhaust plenum when the system is in fire mode. This is in addition to the hood’s automatic fire suppression system. When the fire suppression system discharges, it activates the waterwash system (without the detergent) and the optional continuous cold water mist to spray water within the exhaust plenum and turns on the fan circuit. The system will shut off when the fire protection system is reset. It can also be shut off manually by turning off the water flow in the waterwash control station. Exhaust fan will be on, Supply fan off

Typical Installation:

Page 6

April 2005

SYSTEM COMPONENTS:

Hood:

The hood is shipped from the factory prepiped and ready to install. All waterwash components within the hood are complete and ready for connection to hot water, electrical sources, the sanitary sewer drain and optional cold water. All piping to and from the waterwash control station and the hood is by others. Wiring from the control panel to the hood (for lights) is by others. All plumbing and wiring must conform to plumbing and electrical codes. See Figure 1(previous page) for typical installation and location of electrical and plumbing components.

Duct collars are also mounted at the factory unless requested otherwise.

Waterwash Control Station:

The waterwash control station contains all of the water and electrical controls in two separate compartments. (See Figs. 2, 3, 4, 5, 6 & 7). The electrical side includes all electrical components, connections, and on/off switches. These switches are illuminated and are mounted on the face of the cabinet. The water side includes hot water connections, pressure/temperature gauges, the detergent reservoir and pump, water hammer arrestor, the water solenoid valves, and optional continuous cold water mist piping.

Vacuum Breaker (shipped loose for field installation):

The vacuum breaker is installed at the highest point in the system’s piping to prevent backflow when there is no water pressure to the hood. It must be installed a minimum of 6 in. above the hood water supply line (See Figs. 2, 3 & 4).

Reduced Pressure Backflow Preventer - RPBP (shipped loose for field installation):

Where building codes require a reduced pressure backflow preventer, it will be provided in lieu of a vacuum breaker when ordered. The reduced pressure backflow preventer is installed beneath the control panel (See Fig. 5, 6 & 7). May by ordered mounted in 48 in. tall cabinet.

Detergent Pump-Related Components (shipped loose for field installation—installed in RPBP systems. See page 42 ):

• Detergent line check valve

• Detergent tube (1/4 in. I.D., 3/8 in. O.D.)

Optional Features:

24 Hour / 7 Day Timer:

This feature allows the cleaning cycle to begin at any preset time after the fans are shut down, rather than immediately after. This allows time, for instance, for completion of dishwashing to avoid a shortage of hot water. Fans must be turned OFF just as with the standard cleaning cycle. Maximum six start times.

Multiple Hoods Sequenced Wash:

Where more than one hood must be washed, the control station is set up to wash each hood individually in a prescribed sequence. This ensures that there will be adequate hot water for all hoods. Individual water solenoid valves are provided for each hood to be washed in a multiple sequence. Maximum five sequences.

(Sequence solenoid valves are shipped loose for systems with vacuum breakers or optional continuous cold water mist. They are mounted in the control station for standard systems with reduced pressure backflow preventers.)

Low Detergent Indicator Light:

A sensor and indicator light are available to alert the operator when the detergent tank requires filling.

Continuous Cold Water Mist:

This feature continuously sprays a fine water mist in the exhaust plenum of the hood. The continuous cold water mist is controlled by the same push button switch as the fan.

INSTALLATION

NOTE: If you have a Backsupply Plenum (BSP), this must be installed before the hood. Please

see Page 13.

For Wall/Single Island Style Hoods, prior to installation, check with local authorities having jurisdiction on clearances to combustible surfaces, etc.

With the hood still inside its packing crate, position the unit beneath its installation location. Carefully remove the packing

crate. Place some protective material on the floor next to the crate to avoid damaging the hood as it is tipped on its side. (See Fig. 8) Tip the hood carefully onto the protective material. If you have filler panels, install them now. Please see page 16.

If you have integral filler panels, no additional installation is needed.

Insert

⁄2 in. diameter threaded rod (by others) into hanger brackets on hood top. (Fig. 9, Pg. 10) Check the engineering drawings for proper hood height above finished floor. Greenheck recommends that the hoods be hung 6 feet 6 inches above the finished floor. Raise and hang hood from adequate roof or ceiling supports. All hanger brackets must be used and hood must be properly supported while lifting to prevent damage or distortion to the hood. The hood must be hung level

to or slightly pitched toward the grease drain.

Double Island Style Hoods

Before hanging the hoods, please verify the hood marks to make sure the correct hood is hung on the correct side.

A double island hood is created by installing two wall style hoods back to back. Use the installation procedure described on page 8, for single island hoods to install and level both hoods. After leveling, secure the hoods together by tack welding and/or bolting the rear mounting brackets. Caulk this joint with NSF approved silicone caulk (GE SCS-1009 or its equivalent). The caulk is not provided.

Installing U Channel Trim Strip

1. After the hood is hung in position

and leveled, apply caulk to the inside edge of the double island clip (see detail).

2. Position and install the clip by

tapping into position along clip (friction fit).

3. Caulk edges to seal out grease and allow for ease of cleaning.

Caulk with NSF approved silicone caulk (GE SCS1009 or its equivalent). The caulk is not provided.

Note: The installation of the canopy hoods shall be in accordance with NFPA 96 (latest edition), Removal of Smoke and Grease-laden Vapors from Commercial Cooking Equipment.

See separate instructions for proper installation of enclosure panels, backsplash panels, and end skirts when provided. Please see Pages 15 -19 for the installation instructions.

be hung at 6 ft. 6 in. above the finished floor. This is measured from the lowest rear edge of the Backsupply Plenum to the finished floor. Leave 6 to 10 inches of space below the plenum for access to the air diffusers.)

6. Fasten the Backsupply to the wall, going through the lower Backsupply wall. (See Fig. 12)

INSTALLATION INSTRUCTIONS FOR THE BACKSUPPLY PLENUM BSP

Installing the Supply Duct Collar

1. Find the center of the Backsupply Plenum.

2. If the Backsupply Plenum is less than 9 ft. 10 in. wide, cut opening at

the suggested location, centering the opening over the center of the backsupply Plenum. (see Fig. 10A)

3. If the Backsupply Plenum is greater than 9 ft. 10 in. wide, divide the

width of the backsupply by four. This will give you the center of each half. Cut openings at the suggested location, centering the duct collar over the center measurement of each half. (see Fig. 10B)

4. Place the duct collar(s) over the opening, fastening with screws or tack

welds every four to six inches. (see Fig. 11)

Hanging the Hood

Before hanging the hood according to the hood installation instructions, please check the following:

1. Make sure the Backsupply Plenum is properly secured, as described in steps 5 and 6, page 13.

2. If the ductwork for the Backsupply will not interfere with the hood installation, it should be connected now.

3. Any filler panels should be attached to the hood before the hood installation. See page 16 for instructions.

4. For Canopy Hoods: Lift the hood, and position it so the filler panels are resting lightly on the top outside edges of the Backsupply. The Backsupply is used to position the hood only, it is not intended to hold any hood weight. (See Fig. 13)

5. Connect the remaining ductwork for the Backsupply and the hood. It is recommended that caulk be applied at the mating seams and surfaces of the Backsupply, the hood, and the wall.

Fig. 13

Air Diffusers

The air diffusers, located at the bottom of the backsupply (See Fig. 14), will need to be cleaned as often as the application dictates. Inspect periodically to determine the cleaning schedule.

1. To clean the air diffusers, unfasten the screws. Remove the air diffusers from the Backsupply Unit, and wash in the sink or dishwasher.

2. Insert the air diffusers at an angle from the bottom, and rotate so the forms are downward. Rest the diffuser on the internal angles. (See Fig. 15)

3. Refasten with the stainless steel screws.

Cold Water Requirements

Water Supply 30-60 psi Average water consumption 0.1 gpm per linear foot of hood Set pressure reducing valve to 25 psi on the gauge in the cabinet when running.

3) Water Supply to Cabinet:

Connect hot water supply to waterwash pipe fitting at bottom of control station. Connect cold water supply to optional continuous cold water mist pipe fitting at bottom of control station. The water requirements to the cabinet are detailed in the Engineering Specifications.

Optional Reduced Pressure Backflow Preventer:

Water solenoid valves and detergent line are factory-mounted inside the control panel (See Fig. 5, 6 & 7, page 7). The reduced pressure backflow preventer and strainer (provided) must be field piped in the supply line before the control panel. The backflow preventer relief valve must also be piped to a drain.

4) Control Cabinet to Hood Plumbing:

The waterwash plumbing requires 3/4 in. or 1 in. pipe (by others) depending on the length of hood in each washing sequence. The optional continuous cold water mist plumbing requires 1/2 in. to 3/4 in. pipe (by others) depending on the total length of hood. Only reduce to 3/8 in. at the hood connection.

See the Engineer Specifications for information on the pipe size required.

For Systems with a Vacuum Breaker:

Piping from control station to hood includes a detergent line and a vacuum breaker. The vacuum breaker must be installed at the highest point in the system (and a minimum of 6 in. above the hood water supply line). The detergent line joins the supply line downstream from the vacuum breaker as shown in Fig. 2, 3 & 4, page 7. Where optional solenoid valves are used in systems with multiple hood sequence washing, additional piping must be installed downstream from the vacuum breaker. Hot water/detergent supply pipe connects to hood piping at top rear corner of hood.

5) Drain Connection:

Install hood drain pipe at bottom rear corner of hood as shown in Fig. 1. A 2 inch NPT female fitting is provided. A grease trap is recommended in the drain to avoid clogging the sanitary sewer. If a RPBP is shipped with the control panel, an air gap assembly may be required and will need to be plumbed to a sanitary sewer. See drawing on page 42 of the drawing diagram section of this manual.

2) Optional Continuous Cold Water Mist Engineering Specifications:

Plumbing & Electrical

Page 23

April 2005

B. Electrical Wiring:

All wiring must be done according to NEC (National Electrical Code NFPA #70) and local building codes. A terminal block is provided in the electrical compartment of the waterwash control station for all wiring connections. (See Figs. 21 & 22 on page 24. See also separate wiring diagram.)

Wiring to waterwash control station is 115 VAC, 20 AMP separately fused service.

Wiring from waterwash control station to fan control center is configured as a normally-open dry contact. However, it can be configured by others to provide 115 VAC, 1 AMP (max) control power to the fan control center. If the fans are controlled by a building management system, it may be necessary to reprogram the control panels PLC to eliminate having to push the start fan & start wash buttons to initiate a wash cycle. A 24hour timer is then required to initiate the wash cycle.

Wire hood light switch to junction box on top of hood.

Wire waterwash control station terminals to fire suppression system microswitch in the Fire Suppression Control Cabinet (a normally-closed dry contact switch). If this switch or jumper is not installed, the waterwash system will operate in fire mode continuously. (This is not required but will provide added protection during a fire and the control panel is shipped with a jumper between terminals 5 & 6 which must be removed when connecting to the fire system micro-switch)

For optional sequence washing of multiple hoods, use one of the following:

A) Controls with vacuum breakers (See Fig. 2, 3 & 4, page 7) B) Controls with backflow preventers with waterwash only (See Fig. 5, page 7) C) Controls with optional continuous cold water mist and backflow preventer (See Fig. 6 & 7, page 7)

NOTE: The waterwash control station must be wired to the exhaust fan controls and optionally

to the hood's fire protection system.

Instructions for programming the Waterwash Control Panel (WWCP) 24-hour or 7-day timer

If your waterwash control panel included a timer, either 24-hour or 7-day, it will need to be programmed prior to kitchen start-up. The timer was shipped with a 3-year battery installed and was tested before leaving the factory.

The function of the timer is to start the hood wash sequence after all cooking and dish washing operations have ended for the day, so that all available hot water may be used in washing the hood baffles.

The daily sequence of operations is:

1. Press the “Start Fan” button at the beginning of the day to start the fans.

2. Press the “Stop Fan / Start Wash” button at the end of the day to stop the fans. A. This will initiate the wash timing delay B. To wash the hood immediately, press the “Stop Fan / Start Wash” button a second time.

3. After all wash sequences have been completed, the WWCP will reset for the next day’s operation.

Programming Instructions:

1. Remove the clear plastic cover over the 6 buttons by gently lifting out at the top.

2. Press the “MODE” button until “CLK” is displayed in the upper left corner.

3. Press the “DAY” button until the correct day is shown at the bottom of the display.

4. Press the “H+” and “M+” buttons to set the correct time. “AM” or “PM” is shown at the left side of the display.

5. Press the “MODE” button once. “PRG” should be displayed. A. On the right side of the screen should be a “1” and “ON”. This is the first program.

There are 6 available to use. Normally only one is used for 24-hour timing and the other 5 can be used for 7-day timing.

B. With 24 hour timing, the wash cycle will start the same time everyday.

6. Press the “DAY” button until the correct day or days appear at the bottom of the display. Use “MO TU WE TH FR SA SU” for 24 hour timing.

7. Press the “H+” and “M+” buttons to set the time the wash is to start.

8. Press the “ON/OFF EVENT” button once. “OFF” and “1” should be on the right of the display.

9. Set the off time to be 5 minutes after the on time for this program.

10. If using as a 7-day timer, use the “ON/OFF EVENT” button and repeat steps 6-9 to set the other programs as needed.

11. Press the “MODE” button once. “AUTO” should be displayed.

12. Replace the clear plastic cover over the buttons.

13. The hood may also be manually washed any time the fans are off by pressing the clear plastic button cover. “ON” should appear on the right side of the display.

DETERGENT PUMP:

For proper operation of the detergent pump and wash system, hot water pressure must be between 40 PSI (min.) and 60 PSI (max.). The water temperature range is 140°F to 180°F.

Water pressure, water temperature, grease accumulation, wash cycle length, wash cycle frequency, and the type and amount of detergent used can influence cleaning effectiveness. In very heavy cooking operations, additional washes may be necessary. The wash time can also be increased to a maximum of 10 minutes; the wash time is factory set at four minutes. Consult Fig. 23A to change the wash time. If this is not effective, manual cleaning may be necessary (hand scrubbing, steam cleaning or pressure washing).

Adjusting Detergent Pump Output Rate

Adjustment of the detergent flow may be necessary. Pump must be OFF. Use the following formula to determine proper pump setting: (Adjust pump setting as needed for proper cleaning.)

0.3 oz./min. x Hood Length = Pump Setting The minimum pump setting is #2.

To calculate the number of washes a full detergent tank will deliver for a specific application, use these formulas:

1) Pump setting (oz. per min.) x Wash Length (4.0 min. std.) = Oz. per wash

2) 320 oz. Tank Capacity

= Number of Washes per Tank

Detergent Requirements

The detergent brand SC-5 (by 2010 Products) is recommended by Greenheck for use in the waterwash system. For normal use in Greenheck waterwash hood systems, use SC-5 full strength or as suggested by supplier. This product is biodegradable, non-caustic, and safe for kitchen staff to use. It can also be diluted with one part SC-5 to one part water for cleaning hood exterior surfaces. To eliminate grease from drains, TDW Bio-Enzyme Grease Treatment is recommended. This product contains no harsh chemicals, removing grease, fats, and oils with bacteria and enzymes in a detergent base. Both SC-5 and TDW are manufactured by 2010 Products, Inc., Food Service Division, Salem, Oregon 97303. For details and ordering information, call 800-286-2010.

Preventive Maintenance

The following practices will prolong the life of the detergent pump:

• 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.

• Keep detergent tank filled.

The detergent pump motor has sealed bearings which do not require lubrication.

INITIAL SYSTEM START UP:

1. Check electrical power (see wiring diagram page 24, Figs. 21 & 22)

Correct supply voltage Proper connections to fire suppression system Proper connections to fan control center Proper connections to optional remote solenoid valves

2. Adjust the detergent injector's output (See page 26, Fig 23B)

3. Add detergent to the detergent tank in the cabinet (See page 7, Fig. 4)

4. Flush the piping:

Remove last nozzle from the waterwash piping and from the optional continuous cold water mist piping in the hood. With the cabinet doors closed press the "Start Fan" button. After sufficient time press the "Stop Fan/Start Wash" button twice. After sufficient time open the cabinet doors and replace the nozzles. Clean all strainers in water lines.

5. Close the cabinet doors and press the "Start Fan" button

- Check exhaust and supply air volumes with a pitot traverse or equivalent method (see page 32 for equivalent method)

- Verify optional continuous cold water mist is spraying

- Set the pressure reducing valve on the optional continuous cold water mist to 25 psi on the

gauge provided.

6. Press the “Stop Fan/Start Wash” button. (Press twice if there is a 24- hour timer)

- Verify the waterwash sequence of operation (page 28, Fig. 24).

- During the wash cycle verify the flow of water. Verify the pressure and temperature on the gauge

provided meets the Engineering Specifications (see page 21).

- During detergent pump cycle verify that it is pumping.

Start up checklist available in the appendix.

DAILY OPERATION OF THE WATERWASH HOOD:

Pressing the Start Fan switch will start the exhaust fans, supply fans, and optional continuous cold water mist. This can be done at any time, including during wash cycle operations. The only exception is during fire mode. (See Fig 24).

Pressing the Stop Fan/Start Wash switch shuts down the fans, shuts down the optional continuous cold water mist, and starts the wash cycle. If the system has a 24 hour timer, the wash cycle will begin at the set time. To start the wash cycle independently of the timer, press the Start Fan/Start Wash switch a second time. When the wash is completed, the system will then 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 by-pass having to initiate the wash cycle by pushing the stop fan/start wash button.

Greenheck Waterwash Sequence of Operations

Siemens PLC S7-200, CPU 214 & CPU 224

The intent of the waterwash control panel(WWCP) is to control the operation of the fans and will start the wash cycle upon fan shutdown. If hooked up properly, the fans will be off during wash cycles. If the exhaust fan is being controlled by something other than the WWCP, this panel will still function. To start the wash cycle, you must still press the “Start Fan” and “Stop Fan/Start Wash” buttons. Washing will either start immediately or when the 24 hour timer is tripped. A fan interlock should be installed by others to keep the exhaust fan(s) from sucking water up into the duct(s).

1. Off Mode - At the beginning of a day the following PLC lights will be lit: Run - Should always be on I 0.2 - Signal from fire system. Loss of this signal will initiate “FIRE” mode. I 0.3 - Signal from wash timer (only on at time set on timer). If no timer, this will always be lit.

2. Cooking Mode - Press “Start Fan” button. The following PLC lights will be lit: Run I 0.2 I 0.3 - Signal from wash timer (only on at time set on timer). If no timer, this will always be lit. Q 0.0 - Fans. Combined switching. This will control both exhaust and supply fans. Fan control relay

should be energized. Fans should be on. Optional “Cold Water Spray” solenoid should be energized and water spraying along entire length of exhaust plenum.

Q 0.7 - Supply fan, not wired from factory. Use this if separate switching is required. Supply fan will

shut down or turn off during a fire.

3. Stop Mode - Press “Stop Fan, Start Wash” button. The fans and optional cold water spray will stop. If there

is a 24 hour or 7 day timer, the wash cycle will start at the time set on the timer. If there is no timer, the wash cycle starts immediately. To bypass the timer and start the wash cycle immediately, you can either press the “Start Wash” button a second time or manually trip the timer. The following PLC lights will be lit if not in wash mode:

Run I 0.2 I 0.3 - Signal from wash timer (only on at time set on timer). If no timer, this will always be lit.

4. Wash Mode - Sequence of Operations: 15 seconds cold water purge from piping. Detergent requires hot water. (Optional 30 seconds) 4 minutes wash with detergent. (Optional 0 – 10 minutes)

30 seconds detergent purge to remove detergent from piping. (Optional 1 minute)

15 minutes sequence delay to allow water heater to recover. (Optional 0 – 45 minutes) Repeat the above for each sequence until the last sequence is completed. 1 minute drain down to remove the majority of water from hood. (Optional 10 minutes) 1 minute fans on to remove steam and moisture from hood. (Optional 10 minutes) PLC resets itself for the next days’ operation.

Page 30

April 2005

The “Start Fan” and “Stop Fan / Start Wash” buttons must be pushed everyday for PLC to be reset.

Each sequence can wash up to the following combined hood lengths.

10 feet with

⁄4 in. piping, 20 feet with 1 in. piping, 30 feet with 1

⁄4 in. piping and

45 feet with 11⁄2 in. piping.

The following PLC lights will be lit during wash mode:

Run I 0.2 I 0.3 - Signal from wash timer (only on at time set on timer). If no timer, this will always be lit. Q 0.1 - main wash solenoid valve stays on for entire wash sequence Q 0.2 thru Q 0.6 – wash sequence solenoid valves Q 1.0 - detergent pump on during each wash sequence I 1.5 - last sequence indicator on during last sequence (CPU 214 only) Q 0.0 & Q 0.7 - fans on at end of last sequence

Water requirements:

Water temperature – 140 to 180 degrees Fahrenheit Water pressure – 40 to 60 PSI Average water usage – 1.1 GPM per linear foot of hood (@ 40 PSI)

Detergent requirements: SC-5 from 2010 Products or X-701 from ZEP manufacturing.

BALANCING THE KITCHEN EXHAUST SYSTEM

A. To determine the proper dining room air balance:

1. Refer to engineering drawings to determine total exhaust CFM from dining areas. (Exhaust fans, heating and air conditioning units, restrooms, etc.)

2. Determine the total CFM of make-up air supplied to dining area.

3. Subtract #1 from #2 above. If the result is a negative number, a negative pressure is present in the dining area. In this case, kitchen exhaust odors could be drawn from the kitchen to the dining area. Therefore, exhaust or supply air should be adjusted to provide a slight positive pressure in the dining area.

B. To determine proper kitchen air balance:

1. Refer to engineering drawings to determine total exhaust from the kitchen area. (Exhaust hoods, dishwasher hoods, etc.)

2. Determine total CFM of make-up air supplied to kitchen area. (Make-up air hoods, heating and air conditioning units, etc.)

3. Subtract #1 from #2 above. The result should be a negative number. If the result is a positive number, a positive pressure is present in the kitchen area. Kitchen odors could be forced into the dining area. Also, a positively balanced kitchen area can adversely affect the performance of the exhaust hood.

Caution: According to NFPA 96, Ch. 8-3 Replacement Air : Replacement air quantity shall be adequate to prevent negative pressures in the commercial cooking areas from exceeding 4.98kPa (.02 in. water column).

Measuring Hood Exhaust Volume:

A digital 2-3/4 in. rotating vane anemometer can be used to measure exhaust CFM when the more accurate pilot traverse is not available. Accuracy of the rotating vane anamometer has been tested at +

15%.

Measuring Velocity and Calculating Volume

1. Turn off all cooking equipment and hood supply fan (if applicable).

2. Remove the deflector panel on short circuit hoods.

3. Place the anemometer head in the hood exhaust airstream as shown in Fig. 25. It must be placed in the slot as close to the back wall of the hood as possible and at a 90° angle to it.

4. Take measurements at 8 in. intervals along the entire length of the hood.

5. Calculate the average slot velocity.

6. Calculate the CFM per lineal foot by dividing the average velocity by a conversion factor of 3.9.

7. Calculate the hood's exhaust volume by multiplying the CFM per lineal foot by the length of the hood.

Example:

1. Measured slot velocities in FPM for a hood 4 ft.-0 in.

2. Average slot velocity = (Sum of velocity readings)

(Number of readings)

= 920 + 937 + 924 + 935 + 927 + 925 = 5568 = 928 FPM

3. CFM per lineal foot = Average velocity in FPM

3.9

= 928 = 238 CFM/lineal foot

3.9

4. Hood exhaust volume = (CFM/lineal foot) x (hood length)

= 238 x 4 = 952 CFM

Supply (If Applicable):

Example for Perforated Face Supply

1. Hood set up If the make-up air unit has a temperature control, it should be used to keep the supply air a the desired room

discharge air temperature.

2. Measure Velocities Divide the perforated face panel into a grid of equal areas, each approximately 4 in. square. Measure the velocity at the center of each grid area. A digital 2 3/4 in. rotating vane anemometer or

equivalent is suggested. The center of the anemometer should be held tight to the face of the panel, and parallel to the filter. Both squareness and distance are important for accuracy. Calculate the average velocity of the panel.

3. Measure the length, height, and width of the perforated face panel.

4. Calculate the perforated face panel volume in CFM by using the following formula:

Volume = Avg. Velocity * Length (in.) * Height (in.) * .005

5. Calculate the system’s volume by repeating the process for the remaining panels and adding the individual panel volumes together.

Example: GWFW Hood with (3) 28 in. Perforated Panels

• Measured velocities in FPM for one perforated panel

• Average Velocity= Sum of Velocity Readings

Number of Readings

=260+250+ ... +290+295

= 270.7 FPM

260 250 255 260 250 255 265 270 275 270 280 265 265 270 290 285 280 280 275 290 295 285 275 280 260 270 265 260

• Measure = 28 in. long perforated panels x 16 in. high

Length and Height

• Volume for = 0.005 x ( Average Velocity) x (Length) x (Height)

one panel = 0.005 x 270.7 x 28 x 16 in. = 606.4 CFM

• Total System = (Panel 1 Volume) + (Panel 2 Volume) + (Panel 3 Volume)

Volume = 606.4 + 614.3 + 593.8 = 1814.5 CFM

Page 34

April 2005

TESTING HOOD AIR VOLUME

Short Circuit Hoods

Supply

All cooking equipment should be off. The hood exhaust should also be off.

1. Measuring Velocities

• Velocity measurements should be made with a digital 2-3/4 in. rotating vane anemometer or its equivalent.

• One velocity measurement should be taken for every 8 in. of short circuit opening length, starting tight against one edge of the opening, and finishing tight against the other edge. The anemometer should be placed at the bottom edge of the opening, flush with the bottom lip as shown in Fig. 26. Both squareness and placement are important for accuracy.

2. Calculate the average slot velocity.

3. Calculate the CFM per linear foot by dividing the average velocity by a conversion factor of 5.52.

4. Calculate the hoods exhaust volume by multiplying the CFM per linear foot by the total hood length.

Example: 4 ft. short circuit hood (36 in. short circuit opening).

1. Number of Readings = 36 in. / 8 in. => 6 readings

2. Average Slot Velocity = (Sum of Velocity Readings)

(Number of Readings)

= 786 + 900 + 1126 + 1048 + 1111 + 1115

= 6086 = 1014 FPM

3. CFM per Linear Foot = Average Slot Velocity in FPM = 1014 = 184 CFM / Linear Foot

5.52 5.52

4. Hood Supply Volume = (CFM/Linear Foot) x (Total Hood Length in Feet)

= 184 x 4 = 736 CFM

MAINTENANCE:

Daily

• Hood exterior surfaces should be wiped clean. Use SC-5 brand cleaning solution as recommend in detergent pump section.

Weekly

• Detergent tank should be checked and refilled at least once per week.

• Check nozzles. Clean or replace all clogged nozzles.

• Check drain for clogging.

Monthly

• Detergent system fittings should be checked. This is an airtight system and fittings must be tight.

• After a wash cycle has been completed, open hood inspection panels (See Fig. 27.) and check to ensure that the interior has been cleaned of all grease, dust, lint, etc. If overall cleaning appears to be inadequate, see Troubleshooting and Detergent Pump Sections.

• Check the main grease gutter of the hood for any foreign materials and remove.

Every Six Months

• Check exhaust fans for belt tightness, belt alignment, and lubrication of moving parts.

• Check for proper air volumes.

TROUBLESHOOTING:

Before calling your manufacturers representative to report a problem have the following information available:

1. Review / summary of troubleshooting section in installation operation manual.

2. Hood model and serial number.

3. Current cooking equipment line-up.

4. Size of hood (length, width and height).

5. Island or wall configuration.

6. Multiple hoods on one fan.

7. Nature of spillage (one end; all around the edges).

8. Does the smoke make it to the hood?

9. Height hood is mounted above finished floor.

10. How make-up air is brought into the kitchen (hood, ceiling diffusers, separate plenum).

11. Is exhaust system controlled by a variable volume system or building management system?

12. Is the fan noisy.

Exhaust plenum

Access panel

Exhaust plenum

The access panel is removed by lifting it upward to release the bottom edge bracket and side clips. The panel can then be lifted clear of the hood.

Fig. 27

Page 46

April 2005

Waterwash System

Hood not clean enough

If the hood does not seem to be adequately cleaned, look for the following:

• Water supply — Is it turned on?

• Nozzles — Are any of them clogged? If so, they can be removed and cleared using a small wire.

• Detergent tank — Is it empty, or filled with the wrong detergent?

• Water pressure — Is it above the minimum 40 PSI?

• Water temperature — Is it above the 140°F minimum?

• Detergent pump — Is the mix ratio too low for the type of accumulations on the hood?

• Length of Wash Cycle can be increased. (Consult Factory).

Hot water running, system not in wash cycle

If there is water running through the system when the hood is not in a cleaning cycle, the system may be in fire mode. (Fire mode indicator light will be lit.) Check to ensure that the water wash system is wired to the fire system microswitch and that there is a jumper between terminal s 5 & 6 on the PLC.

Hot water running continuously after wash cycle, detergent pump not running

If water is spraying, but the detergent pump is not running (and fire mode and wash indicator lights are off) the solenoid valve may be stuck in the open position. To correct:

• Gently tap the valve housing to release any foreign material trapped in the valve.

• If this does not correct the problem, it is necessary to remove the valve coil and stem.

CAUTION: Turn off electrical power before disassembling valve. Clean valve coil and stem,

and re-install very carefully to avoid damaging the plunger.

• Check valve diaphragm for failure. If it has failed, rebuild it. Kits of various sizes are available. See the Waterwash Start-up Checklist on page 52.

• If solenoid sticks regularly, foreign material getting past the building's line strainer is the most likely cause. Remove and clean the strainer, or install an additional strainer in line before the waterwash cabinet.

Washindicator light on, no hot water running

If the Wash Cycle indicator light is lit, but water is not spraying, look for the following:

• Shut off valve — This valve, located inside the control station, must be in the open position.

• Water Solenoid valve

- Check to be sure that water solenoid valve is getting power at the terminal strip.

- Check electrical continuity to determine if coil has burned out.

- Gently tap the valve housing to release any foreign material trapped in the valve.

• If the above steps do not correct the problem, it is necessary to remove the valve coil and stem.

CAUTION: Turn off electrical power before disassembling valve.

Clean valve coil and stem, and re-install very carefully to avoid damaging the plunger.

If after checking all components, the problem continues, check the wiring circuit. See wiring diagram.

Water leaks

• Check all pipe fittings.

• Ductwork may not be liquid tight as required.

• Are the access panels fitting snugly together? Fingers and clips may need to be adjusted.

• Are the fans running during the wash cycle? Fan should be off during wash. Ensure that power to the fan is running through terminals 3 & 4 on the waterwash control panel.

• Is the water pressure too high? Turn the pressure down to 40 psi.

Page 47

April 2005

Vacuum breaker problems

If the vacuum breaker leaks or seems to snap at the beginning or end of a cycle, check the following:

• Mounting height — The vacuum breaker must be mounted a minimum of 6 in. higher than

the line to the hood.

• Nylon check valve travel — Remove the top cap of the vacuum breaker and determine if

the nylon check valve is free to slide up and down the guide stem properly and that the stem is straight.

• Rubber washer — Determine if the washer on top of the check valve seats properly

against the machined surface and that the mating surfaces of both are smooth. Replace if necessary.

Poor drainage

If the hood does not drain properly, look for the following:

• Clogged outlet — Clear any foreign material (paper towels, rags, etc.) from the hood’s

internal drain outlet.

• Clogged grease traps — Where grease traps are installed, they may become clogged

and cause drains to back up. If so, they must be kept clear.

• Drain size inadequate — Drains should be a minimum of 1-1/2 in. dia.

Optional Continuous Cold Water Mist

If the fan runs but no cold water, check for the following:

• Shut-off valve closed

• Clogged strainer in the pressure reducing valve.

• Water solenoid valve

- Check to be sure that water solenoid valve is getting power at the terminal strip.

- Check electrical continuity to determine if coil has burned out.

- Gently tap the valve housing to release any foreign material trapped in the valve.

• Nozzles may be plugged.

If cold water is running after the fans shut-off, check the following:

• Solenoid may be stuck in the open position.

• Is the system in fire mode?

If water leaks from top of the hood then:

• Check all pipe fittings

• Ductwork not liquid tight as required.

If little or no water spraying from the nozzles look for:

• Nozzles plugged and need to be cleaned.

• Verify the water pressure above 25 psi.

• Clogged strainer located in the pressure reducing valve.

• Water supply system not properly flushed.

Reduced pressure backflow preventer (RPBP) may spit small amounts of water as fixtures upstream are used. Air gap assembly may be needed to catch drips and drain them away to a sanitary sewer.
