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

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.

Model GGH2O

Installation Overview

Filler Panels

1. Unpack the hood and lay it on the lifting skid.
