Kitchen Roof Mounting Installation

UL/cUL 762 installation are for restaurant applications.

1.The size of the duct must be equal to the inlet opening.

2.Secure the fan to curb at all four corners using a minimum eight anchor bolts, lag screws or other suitable fasteners.

3.Use optional grease trap and external junction box.

4.Area codes may require a continuous weld between duct and inlet.

5.To comply with NFPA 96, the discharge is required to be a minimum of 40 inches (1016 mm) above the roof deck and a minimum of 10 ft. from any building air intake. The minimum velocity in the duct should be 500 ft/min. or greater.

6.Ductwork to an upblast discharge exhaust fan is

constructed of carbon steel not less than 16 MSG (1.6 mm) and extends a minimum of 18 inches (457 mm) above the roof surface.

7.Ensure that a minimum of 500 ft/min. of air velocity through the fan is maintained per NFPA 96, clause 8.2.1.1, 2008 edition and UL 762, Issue #5, December 19, 2003, clause 6.2.

Trap

A grease trap is an aluminum trap designed to collect grease residue to avoid drainage onto roof surface. It contains a built-in water separating baffle.

Instructions

1.

Apply cover to grease trap. Install clip nuts to trap

 

over holes provided. Attach cover with two #10 - 24

 

x 1/2 fasteners.

2.

Position the container under the grease drain so the

 

drain spout enters the cover approximately 112 to

 

2 in. (38-51 mm).

3.

Locate and mark the container mounting holes on

 

the extended base or roof curb.

4.

Drill 3/16 in. (5 mm) diameter holes in marked

WARNING

In a kitchen exhaust application, do not use a speed control or isolation damper.

NOTE

In a kitchen fan and high temperature applications exhaust upblast fans must have external wiring.

5.

Apply container with #10 - 24 x 3/4 fasteners.

6.

For most climates, fill container with water (at

 

installation and after each cleaning) until it flows out

 

the drain hole. The unit is now ready for use.

Maintenance

Regular inspection of grease trap is recommended. Depending on the amount of grease discharged through the fan, the grease trap should be changed accordingly to ensure proper operation.

Vektor-HS, Vektor-H specifications

Greenheck Fan Corporation, a leader in air movement and control equipment, has developed the Vektor-H and Vektor-HS series to meet the growing demands for energy efficiency and performance in commercial and industrial ventilation systems. These models are specifically designed to provide optimal airflow while minimizing energy consumption.

The Vektor-H model stands out with its innovative backward-inclined centrifugal fan wheel, which effectively handles air volumes ranging from 1,000 to 150,000 CFM. This design minimizes turbulence and enhances performance, ensuring quiet operation even at high speeds. The Vektor-H also features a direct drive option that eliminates the need for belts and sheaves, reducing maintenance while increasing reliability. The inclusion of a high-efficiency motor further exemplifies its commitment to energy savings.

On the other hand, the Vektor-HS, or High-Static version, is designed for applications requiring higher static pressure. This capability makes it ideal for systems where long duct runs or highly restrictive applications are involved. With airflow capabilities similar to the Vektor-H, the Vektor-HS is capable of operating efficiently in conditions that demand advanced pressure performance.

Both models come equipped with Greenheck’s advanced controls and monitoring systems, which provide real-time data on performance metrics. These features allow facility managers to optimize the system based on actual operating conditions, thereby improving energy efficiency and reducing operational costs.

Technologically, the Vektor-H and Vektor-HS series utilize advanced acoustic design principles, which significantly reduce noise levels. The application of sound-dampening materials and strategically designed fan casings helps in achieving a quieter working environment, addressing one of the common concerns in HVAC systems.

Furthermore, the Greenheck Vektor series is built with durability in mind. The construction involves heavy-gauge steel and corrosion-resistant finishes, ensuring long-lasting performance even in harsh environments. Both the Vektor-H and Vektor-HS are also customizable, allowing for modifications to meet specific application requirements, such as different mounting configurations and discharge orientations.

In summary, the Greenheck Vektor-H and Vektor-HS series represent the fusion of advanced technology with practical applications, resulting in efficient, durable, and quiet ventilation solutions suitable for a variety of industrial and commercial settings. These models not only address the current needs for energy efficiency and performance but also position users favorably for future advancements in HVAC technology.
