Installation, Operation and Maintenance Manual

Please read and save these instructions for future reference. Read carefully before attempting to assemble, install, operate or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage!

Type IIType I

General Safety Information

Only qualiﬁed personnel should install this system. Personnel should have a clear understanding of these instructions and should be aware of general safety precautions. Improper installation can result in electric shock, possible injury due to coming in contact with moving parts, as well as other potential hazards. Other considerations may be required if high winds or seismic activity are present. If more information is needed, contact a licensed professional engineer before moving forward.

DANGER

Always disconnect power before working on or near a fan. Lock and tag the disconnect switch or breaker to prevent accidental power up.

CAUTION

When servicing the fan, motor may be hot enough to cause pain or injury. Allow motor to cool before servicing.

CAUTION

Precaution should be taken in explosive atmospheres.

1. Follow all local electrical and safety codes, as well as the National Electrical Code (NEC), the National Fire Protection Agency (NFPA), where applicable. Follow the Canadian Electrical Code (CEC) and ULC-S650 in Canada.

2. The rotation of the fan wheel is critical. It must be free to rotate without striking or rubbing any stationary objects.

3. Fan motor must be securely and adequately grounded.

4. Do not spin fan wheel faster than maximum cataloged fan rpm. Adjustments to fan speed signiﬁcantly affects motor load. If the fan RPM is changed, the motor current should be checked to make sure it is not exceeding the motor nameplate amps.

5. Do not allow the power cable to kink or come in contact with oil, grease, hot surfaces or chemicals. Replace cord immediately if damaged.

6. Verify that the power source is compatible with the equipment.

7. Never open access doors to a duct while the fan is running.

Kitchen Hoods • Type I and Type II

Receiving

Upon receiving the product, check to make sure all items are accounted for by referencing the packing list and ensuring 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 ﬁled with 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. Filters are shipped on a separate skid in their original packaging. Do not remove factory packaging or install ﬁlters until just prior to commissioning. Remove all other shipping/packing materials including fan tie down straps.

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.

INDOOR - 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 buildup. Leave coverings loose to permit air circulation and to allow for periodic inspection.

OUTDOOR - Units designed for outdoor applications

may be stored outdoors, if absolutely necessary. Roads or aisles for portable cranes and hauling equipment are needed.

The unit should be placed on a level surface to prevent water from leaking into it. The unit should be elevated on an adequate number of wooden blocks so that it is above water and snow levels and has enough blocking to prevent it from settling into soft ground. Locate parts far enough apart to permit air circulation, sunlight, and space for periodic inspection. To minimize water accumulation, place all unit parts on blocking supports so that rain water will run off.

Do not cover parts with plastic ﬁlm or tarps as these cause condensation of moisture from the air passing through heating and cooling cycles.

Inspection and Maintenance during Storage

While in storage, inspect fans 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. At each inspection, rotate the fan wheel by hand ten to ﬁfteen revolutions to distribute lubricant on motor. Every three months, the fan motor should be energized. If paint deterioration begins, consideration should be given to touch-up or repainting. Fans with special coatings may require special techniques for touch-up or repair.

Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur. Immediately remove the original rust preventive coating with petroleum solvent and clean with lintfree cloths. Polish any remaining rust from surface with crocus cloth or ﬁne emery paper and oil. Do not destroy the continuity of the surfaces. Wipe thoroughly clean with Tectyl® 506 (Ashland Inc.) or the equivalent. For hard to reach internal surfaces or for occasional use, consider using Tectyl® 511M Rust Preventive or WD-40

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.

• Check all fasteners, set screws on the fan, wheel,

• Rotate the fan wheel(s), where applicable, by hand

Installation

Wall or Single Island Style Hoods

NOTE

If you have a back supply plenum (BSP), this must be installed before the hood. Please see page 5.

The installation of the canopy hoods shall be in accordance with NFPA 96 (latest edition) Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations and ULC-S650 in Canada.

Greenheck does not recommend walking or standing on the hood top as damage can result and may void the warranty. If you must walk on the hood top, protect the hood with additional support and planks for flooring.

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. Tip the hood carefully onto the protective material. If you have ﬁller panels, install them now; refer to page 5, Filler Panel Installation. If you have integral ﬁller panels, no additional installation is needed.

Hanging the Hood

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

1. Make sure the back supply plenum is properly secured, as described on page 5.

2. If the ductwork for the back supply 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 5 for instructions.

4. Lift the hood, and position it so the ﬁller panels are resting lightly on the top outside edges of the back supply. The back supply is used to position the

hood only, it is not intended to hold any hood weight.

Hood Installation Overview

If a back supply plenum is provided, install it ﬁrst. Before raising the 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 the hood from adequate roof or ceiling supports 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 the hood is secured, make the exhaust duct connections. The ﬁre system distributor 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 before the enclosures. Finally, make the electrical connections from the switches to the fans and complete the ﬁre system circuits as required by the job speciﬁcation.

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

6. If the hood is equipped with clearance reduction methods, refer to page 8 for special considerations with hanging the hood.

Clearance Reduction Methods

Clearance reduction methods have been evaluated and tested and are listed by UL (Underwriters Laboratory). The method of test was derived from the UL 710 test standard.

The hood may be installed with zero clearance to combustible materials if constructed in the following manner.

1. One inch (2.54 cm) thick layer of insulation of Owens Corning® Type 475, Johns Manville Type 475, IIG® MinWool-1200® Flexible Batt, or Knauf Insulation Type EI 475.

2. Insulation must be held securely in place. Pins that are welded or secured with an adhesive may be used.

3. A backsplash panel must be attached to the wall (insulated or uninsulated).

To comply with the UL listing, the cooking appliances must be as follows:

• Maximum surface temperature is 700°F (371°C)

• Appliances are located at least 3 in. (7.62 cm) from the rear wall

• Appliances are at least 40 in. (101.6 cm) below the bottom front edge of the hood

The hood may be installed with 3 in. (7.62 cm) clearance to limited combustible materials per NFPA 96 if constructed in one of the following methods:

• 3 in. (7.62 cm) rear uninsulated stand-off

• 3 in. (7.62 cm) top enclosure panel system

• 3 in. (7.62 cm) end uninsulated stand-off

Top Clearance Reduction Options

One inch (2.54 cm) layer of insulation installed on top of the hood (optional) meets zero inch requirements for clearance to combustible surfaces as outlined under the clearance reductions methods.

Three inches (7.62cm) insulated airspace installed on top of hood (optional) meets NFPA 96 requirements for clearance to limited combustible surfaces.

Back and Front Clearance Reduction Options

One inch (2.54 cm) layer of insulation in 3 in. (7.62 cm) back stand-off meets zero inch requirements for clearance to combustible surfaces as outlined under the clearance reduction methods.

Three inches (7.62 cm) uninsulated back stand-off meets NFPA 96 requirements for clearance to limited combustible surfaces.

One inch (2.54 cm) layer of insulation factory-installed on the front of the hood (optional) meets zero inch requirements for clearance to combustible surfaces.

End Clearance Reduction Options

One inch (2.54 cm) layer of insulation factory-installed on the end of the hood (optional) meets zero inch requirements for clearance to combustible surfaces under the clearance reduction methods.

Three inches (7.62 cm) uninsulated airspace installed on end of hood (optional). Meets NFPA 96 requirements for clearance to limited combustible surfaces.

Installing Enclosure Panels

Installing End Skirts

Before installing the enclosure panels, make sure the hood is hung in position with all the ductwork attached and electrical connections completed.

1. Position the end enclosure panels on the hood, and clamp into place with clamps provided or tack-weld the panels into place.

2. Fasten the end enclosure panels to the wall, method depends on wall construction. (Fasteners provided by others).

If the hood is a double island, bolt the end enclosure

panels together. (Fasteners provided by others).

3. Position the front enclosure panel(s) on the hood, and bolt to the end enclosure panels with the 5/16 in. bolts provided in the hardware package.

4. Tack-weld or clamp the front enclosure panel(s) to the hood. If clamps are used, they must be positioned 4in. (10.16 cm) from the ends and in the center of the front enclosure panel.

5. To allow for ease of cleaning, caulk the external seams with NSF Approved silicone caulk (GE SCS1009, or its equivalent). The caulk is not provided.

6. Installation instructions may not be applicable for concrete ceilings.

1. After the hood is hung in position, line up the top of the end skirt with the end panels of the hood.

2. Drill a hole in the hood end panel to line up with the hole in the end skirt. Attach the end skirt with a 1/4in. bolt and cap nut to the inside of the hood, or tack-weld the end skirt to the hood.

3. Position the end skirt against the wall and attach. The method depends on the wall construction. (Fasteners provided by others).

4. Caulk the internal joint formed by the end skirt and the hood end panel with NSF Approved silicone caulk (GE SCS1009 or its equivalent). The caulk is not provided.

5. To allow for ease in cleaning, also caulk all the external seams.
