Detergent Dispenser

General: The detergent dispenser supplies detergent to the wash system during the WASH mode. The detergent dispenser is designed to operate for

the entire duration of the WASH mode (2 minutes), and the amount of detergent delivered is regulated by the flow control valve. The detergent reservoir holds approximately 55 gallons of detergent. The DETERGENT LOW light will illuminate when the amount of detergent in the reservoir drops below eight

(8)gallons. The reservoir should be refilled as soon as possible after the DETERGENT LOW light comes on, to ensure that detergent is dispensed and to prevent pump damage.

NOTE

The detergent pump motor will not operate while the detergent low light is illuminated.

Adjustments

The liquid level sensor was setup during field inspection and should not require adjustment.

Flow Control Valve Adjustment

The detergent dispenser will be adjusted during commissioning to a detergent-to-wash water ratio of 1:20, meaning one gallon of detergent is used for every 20 gallons of wash water used. In some applications, the amount of detergent used may need to be increased. This may be done by adjusting the flow control valve on the upper left front of the detergent dispenser.

Adjustments to the flow control setting should be done in small increments over a period of several wash cycles. Turning the knob clockwise, increases the amount of detergent used during a wash cycle.

Maintenance

Routine service is required in order to ensure optimum performance and reliability of the system.

A. Aluminum Mesh Pre-filters & Post Filters: These metal filters in the precipitator should be removed and thoroughly cleaned on a minimum two (2) week interval, removing any grease and particulate buildup.

B. Ionizing-Collecting Cells: The ionizing-collecting cells should be inspected for grease build-up on a monthly basis. This monthly inspection should be done after the system has completed a wash cycle. If grease build-up is apparent, remove cells and clean manually. The cells should be removed and manually cleaned every 6 months minimum.

C. Safety Bag Filters: Safety filters change out frequency depends on the volume of cooking. Change filters every 3 months or prior to an increase in resistance that affects hood capture efficiency. See ordering instructions in this manual.

D. Activated Carbon Panels: Carbon panel change out frequency is also dependent on the volume of cooking. Replace when an increase in odor breakthrough is first noticed. Change out should range between 3 and 6 months.

E.System Fan/Motor: Fan, motor and drives should be inspected, serviced and cleaned according to the manufacturer’s instructions, annually.

F.Wash System Detergent: Greenheck specifies GLT-33 detergent, manufactured by Green Ladder Technologies. This detergent has been specially formulated for this type equipment, and will help ensure successful operation and optimum performance. GLT-33 should also be used to manually clean mesh filters and ionizing-collecting cells. Substituting other types of detergent may result in decreased system performance, system shutdown or voided limited warranty. See detergent ordering instruction sheet in this manual.

The direct drive system eliminates the need for belts and pulleys, reducing the risk of failure and downtime. Moreover, it allows for a more compact design, making installation simpler and space-saving.

The technology behind the Greenheck Fan 474754 also emphasizes noise reduction. With fully integrated sound attenuation features, this fan operates quietly, making it suitable for environments where noise levels need to be kept to a minimum. This is particularly valuable in commercial spaces like offices, restaurants, and healthcare facilities.

Performance-wise, the Greenheck Fan 474754 is designed to deliver high static pressure capabilities, making it effective for applications that require the movement of air against significant resistance. This characteristic is critical for systems involving long duct runs or high-efficiency filters. The fan's adjustable speed motor further enhances versatility, allowing users to tailor airflow rates to their specific needs.

Furthermore, this model is equipped with advanced control options, allowing for automation and remote monitoring. Compatibility with building management systems means the fan can be integrated into an overall HVAC solution, providing users with enhanced control over their indoor environment.

In summary, the Greenheck Fan 474754 is a high-performance, energy-efficient solution ideal for various ventilation applications. Its durable construction, direct-drive motor, noise reduction capabilities, and advanced control options make it a reliable choice for those looking to optimize their air movement solutions in a range of settings. This makes it an invaluable asset for efficient and effective ventilation management.
