Vent-A-Hood® - Owner Maintenance and Repair Topics

Hood Cleaning

For your kitchen ventilation system to work properly, it is important to clean the blower system, vents, and kitchen range hoods regularly. With a regular cleaning program, your kitchen ventilation system and range hood will run at its optimum level for several years.

The cleaning procedure is similar for most models, but please review the procedure you’re your model, such as the model with the Magic Lung® Technology or a model equipped with the K250 blower or the RM1000/RM1500 exterior blowers.

Hood Cleaning Models with the Magic Lung:

Hood Canopy

Wipe down the interior and exterior of the hood as needed with a soft cloth and warm soapy water (liquid dish detergent is acceptable). Do not use acids, abrasives, strong detergents, solvents, or scouring pads. Stainless steel should be treated with a quality stainless steel cleaner such as Stainless Steel Magic® (Vent-A-Hood® part number SS64). Follow all label instructions. Do not polish across the grain or in circles.

Real brass, real copper and hammered copper hoods will oxidize and/or tarnish over time. Use a quality copper or brass cleaner such as Red Bear Copper Polish (Vent-A-Hood part number CP101). Follow all label instructions. Do not polish across the grain or in circles. Do not use acids, abrasives, strong detergents, degreasers, solvents, or scouring pads.

Blower Unit

WARNING: To reduce the risk of personal injury, be sure the power is turned off in the hood before removing the shield(s) and blower housing(s).

The Vent-A-Hood® Magic Lung® blower captures grease by-products in the blower housing(s). Cooking habits determine how often the blower housing(s) will need to be cleaned. High fat content foods and heavy cooking may require cleaning after each use.

To remove the blower housing(s) and damper(s), first remove the blower shield (A). This is accomplished by loosening the two thumb screws on the bottom of the shield. The blower housing is removed for cleaning by un-snapping the suitcase latches (B) (one on each side of the housing). Then, pull the housing forward and gently “tip” it downward to clear the blower wheel(s). The damper can now be unclipped from the inside of the blower housing.

Red Switch- This switch operates a two speed motor. This two speed motor allows the user to switch the hood to “LOW” (position I) for quieter operation during light cooking, while the “HIGH” (position II) setting delivers the full power of the Magic Lung® blower unit. If the two speed motor is turned to “LOW”, the heat sensor (SensaSource®) monitors cooking activity. If the heat reaches an unacceptable level inside the hood, or a range fire occurs, the two speed motor will switch from “LOW” to full power automatically. The sensor will return the motor to the “LOW” level when the heat subsides or the hood may be turned off manually (middle position).

Red Switch

White Switch- This switch controls the lights. “LOW” level lighting (position I) is 25 watts per bulb, “HIGH” level lighting (position II) is 50 watts per bulb. Off is in the middle position.

White Switch

Black Switch- This switch operates a single speed motor. The single speed motor is either off or on, and is not controlled by the SensaSource® heat sensor.

Black Switch

Note: The location of the switches on the hood corresponds to the location of the motors in the hood (i.e. left switch operates left motor, etc. ) except for a T400H Island 1200 CFM Cluster Blower, which is diagrammed below.

Fluorescent Lights

On fluorescent light models, motors are switched independent from one another, with the exception of island hoods which are switched in pairs of motors. When using the hood, the user should generally start with one motor, and then turn on additional motors as required.

White Switch- This switch controls the light(s).

White Switch

Black Switch- This switch operates a single speed motor or a pair of single speed motors in an Island hood.

Operating Instructions – RM1000/RM1500 models

On external blower models, the user should generally start on the lowest setting and then increase speed or turn on additional motors blowers as required.
The light switch operates halogen lights low, off, or high, and fluorescent lights off or on.

Note: In order to properly capture the maximum amount of oil/grease from cooking, the motor blower should be operated at the higher setting – lower speeds may lower the noise level, but may not create sufficient air flow and pressure through the filter to liquefy oil/grease properly.

Operating Instructions – Models with K250 Blower
When using the hood, the user should generally start with the hood on the low setting, and switch to the high setting as required.
