Receiving and Handling

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 to be sure that all parts of the shipment, including accessories, are accounted for.

STORAGE If a kitchen hood must be stored prior to installation 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.

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

Hood Weights

Hood weight is determined using a simple formula. Select the ﬁgures provided in columns A and B (see tables) from the three respective categories—Hood Width, Filter Type and Hood Height—based on the hood received. Total the three numbers in column A and the three numbers in column B. Place the sum for column A and the sum for column B in the Hood Weight equation where shown and solve for the total Hood Weight.

the hood. Please see page 8 now.

Prior to installation, check with local authorities having jurisdiction on clearances to combustible surfaces.

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 (Fig. 1). Tip the hood carefully onto the protective material. If you have filler panels, see Fig. 2 below. If you have integral filler panels, no additional

installation is needed.

Hood Installation Overview

If a Back Supply Plenum is provided, install first. Before raising hood, insert 1/2 in. (12.7 mm) diameter threaded rod (by others) into hanger brackets on hood top. Check the engineering drawings or UL label located on the inside of the hood for proper hood height above finished floor. Install filler panels if needed. Raise and hang hood from adequate roof or ceiling supports and secure mounting flange to the wall using lag bolts, or fasten to the Back Supply Plenum if provided. All hanger brackets must be used and the hood must be properly supported while lifting to prevent damage or distortion to the hood. The hood must be hung level to operate properly. After hood is secured, make the exhaust duct connections. The fire system distributer must be contacted at this time. After the fire system has been installed, mount the enclosures, then the supply plenums. If a Horizontal Supply Plenum is provided, it should be installed according to the external supply plenum installation section found on page 7. The hood and accessories are now installed. Finally, make the electrical connections from switches to fans and complete the fire system circuits as required by the job specification.

Rear Filler Panel Installation Instructions

Rear filler panels may be shipped loose for field installaton or are integral to the hood. If fillers are integral to hood, skip this section.

1. Uncrate the hood and lay it on the floor with protective material between the hood and the floor.

2. Bolt the filler panels together with 5/16 in. bolts from the hardware package.

3. Position the filler panels on the hood, and tackweld them to the hood back.

Exhaust Air Balancing Baffles (EABB)

This is a guide to assist in determining if multiple hoods on one fan can be balanced to have equal static pressure. For multiple hoods on one fan to achieve their designed exhaust flow, all of the hoods must have equal static pressure at their designed exhaust flow.

The laws of physics force the static pressure for each branch of a duct system on one fan to always be equal. This will happen by the flow rate increasing in low static branches and decreasing in high static branches until the static pressure is equal in all branches.

Checking for Balance

Every hood with Exhaust Air Balancing Baffles (EABB) has a range for its static pressure. The low number in this range is given by the standard calculation for hood static. (Static that is printed with the CAPS submittal). The maximum increase above the low number can be calculated from the duct velocity at the low static, (also given on CAPS submittal). This is then added to the low number to get the highest static pressure possible with an EABB.

The maximum potential increase in static is given in the graph, or can be calculated from:

Max. Increase = 0.00000036 x (Duct velocity)

After the range for each hood is calculated, it should be compared to the hood with the highest static pressure. If the highest hood falls inside of the range, then the hoods can be balanced with the EABB. If it is higher than the range, the hoods cannot be balanced.

Example 1:

Hood 1: Ps = 0.58 in. wg

Duct Velocity = 1900 FPM

Hood 2: Ps = 0.44 in. wg.

Duct Velocity = 1800 FPM

Hood 2 has the lower Ps, at 1800 FPM the maximum increase in Ps is 1.17. The range for Hood 2 is

0.44 to 1.61. Hood 1 is less than 1.61 so these hoods can be balanced.

Example 2:

Hood 3: Ps = 2.00 in. wg

Duct Velocity = 2000 FPM

Hood 4: Ps = 0.44 in. wg

Duct Velocity = 1500 FPM

Hood 4 has the lower Ps, at 1500 FPM the maximum increase in Ps is .81. The range for Hood 4 is 0.44 to 1.25. Hood 3 is higher than 1.25 so these hoods cannot be balanced.

Note 1: For many systems, an EABB may not be needed on the hood that has the highest static pressure. The exception to this is if the individual ductwork has uneven static pressures.

Note 2: When sizing the fan, use the static pressure from the highest hood and sum the CFM from all the hoods.

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 area(s) from exceeding 4.98 kPa (0.02 in. water column).

Testing Hood Air Volume

Baffle Filter Style Hoods

A. Exhaust:

With all the filters in place, determine the total hood exhaust volume with a rotating vane anemometer as follows:

1. All cooking equipment should be on.

2. Measure the velocities

Velocity measurements should be

taken at five locations per filter. These must be over a filter slot as in Fig. 21.

square.

Measure the velocity at the center of each grid area. A digital 2.75 in. (70 mm) 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.

Maintenance

Daily Maintenance

1. Wipe grease from exposed metal surfaces on the hood interior using a clean, dry cloth.

2. Visually inspect the filters for grease accumulation. Wash as needed.

3. Remove grease cup, empty contents, and replace cup.

Weekly Maintenance

1. Remove the grease filters and wash in dishwasher or pot sink. Note: Filters installed over heavy grease producing equipment may require more frequent cleaning.

2. Before replacing filters, clean the interior plenum surfaces of any residual grease accumulations.

Periodic Maintenance

Stainless steel hood exterior surfaces should be cleaned with a mild detergent and then polished with a good grade stainless steel polish to preserve the original luster.

Note: Never use abrasive cleaners or chemicals on hood surfaces. Never use chlorine based cleaners or iron wool pads to clean the hood. They may scratch or mar the material and promote corrosion. Always rub with the grain of the stainless.

Proximity Hood

Grease Grabber™ Multi-Stage Filtration System

For use in Model GG__ Canopy Hoods Only

Installation

Note: Never install the Second Stage filter in the front filter channel. The Second Stage filter must be installed behind a UL Classified Grease-X-Tractor™ primary filter Model HE or GX.

1. Slide the top edge of the Second Stage filter into the top rear filter channel; Fig. 41.

2. Lifting the lower edge of the filter past the grease trough, continue to push the top of the filter into the channel.

3. When the filter is even with the bottom rear filter channel, set the filter into the channel; Fig. 42.

4. Slide the filter to one end of the hood and repeat until all the filters are installed. Make sure the filters are placed tightly together with no visible gaps.

5. Latch filters together by connecting hooks to handle on next filte; Fig. 43.

6. Install the Grease-X-Tractor™ primary filters in the same manner using the front filter channel.

Note: Required washing frequency is dependent on type of cooking and quantity of food cooked.

- Remove filters from hood and place each filter in a whirlpool sink or dishwasher.

- If using a whirlpool sink, cycle for 10 minutes. Use standard dishwash soap. (4A)

- If using a dishwasher, cycle it three times to ensure all grease is removed. (4B)

- If using standard sink, cover with hot water and degreaser and soak for two hours. Rinse after soaking.

Note: For hoods with large quantities of filters, it is acceptable to wash 3 to 4 filters each day, cycling all of the filters in three days. Note: The beads will discolor. Standard cooking will turn the beads yellow in color. Open flame cooking will cause the beads to

blacken. Neither affects the performance of the filters.

Periodic Inspection:

- Each filter may be soaked in hot soapy water for two hours once a month prior to washing if grease build-up is found.

- Inspect the filters by holding it up to a light. Light shining through more than six holes in a group indicates filter damage.

- For filter replacement, call 1-800-337-7400

4A 4B Step 5 Replace GG filters in hood. Do Step 3 in reverse order. (3C, then 3B, then 3A) Step 6 Latch filters together by connecting the hooks to the handle on the next filter. Slide hook on from the top and bottom

of the handle. Do not try to snap the hooks into place. Do Step 2 in reverse.

Step 7 Replace the front GX filters. Do Step 1 in reverse. Be sure to install filters in the ends of the hood first, then install the

filters in the middle of the hood (1B, then 1A)

Caution: To prevent damage to filter media, do not wash second stage filters in detergents that contain hydroxides such as sodium hydroxide or potassium hydroxide.

Troubleshooting

Problem: Exhaust fan is not operating or is not operating at design levels.

Is the fan receiving power? Replace fuses, reset circuit breakers, check disconnect.

Is the belt loose or broken? Replace or tighten belt.

Is the fan rotating in correct direction? Have the electrician correctly wire the fan.

Is the make-up air operating?

Does the airﬂow need to be increased? Adjust or replace pulleys to increase fan RPM, install a larger motor.

Does the fan vibrate?

Problem: Hood is full of smoke. There is smoke coming out of the edges of the hood.

Is the fan operating at design levels? See exhaust fan troubleshooting section.

Is the fan correctly sized?

Are the ﬁlters in good condition? Clean ﬁlters, replace damaged ﬁlters, properly position ﬁlters.

Is there sufﬁcient make-up air?

(Kitchen should be in a slight negative but not excessive. Check to see if there is a strong draft through an open door).

Does the current cooking equipment match the original design?

Are there multiple hoods on one fan?

Are there closed dampers in the duct? Open dampers.

Is the ductwork complex or to small? Change to a higher static fan, modify the ductwork.

Is the ductwork obstructed? Clear obstruction.

Is this a short circuit hood? Turn off or reduce the amount of air supplied to short circuit.

Problems with make-up air may interfere with the exhaust fan check the manufacturers installation manual.

Clean the fan wheel/blade, replace fan wheel if damaged, check for loose bolts, check for broken or damaged components, check for rags and other foreign objects.

Refer to test and balance report, design speciﬁcations and fan curves; have an electrician check the motor amperage; try removing the ﬁlter temporarily to see if capture improves. (Make sure to replace ﬁlter to prevent risk of ﬁre!); switch to different ﬁlters with lower static pressure.

Check make-up air unit, increase make-up air, make-up air should be evenly distributed throughout the kitchen.

Adjust or replace fan to match the cooking equipment load.

One hood may be over exhausting and the other hood not drawing enough. Restrict second hood to help problem hood.
