This article provides a detailed, step-by-step installation guide, maintenance instructions, and technical specifications based on official documentation and installation manuals provided by the manufacturer.
Installation Overview
Before beginning the installation process, it is essential to understand the key specifications and requirements for each model. The COS-30IRHP is designed for insert mounting and is ideal for custom cabinetry applications. The COS-6324EWH, on the other hand, is a wall-mounted unit suitable for kitchens with limited space. Both models feature 3 fan speeds, LED lighting, and ARC-Flow filters that ensure efficient grease and odor extraction.
The installation process involves several critical steps, including measuring the cutout dimension, preparing the mounting area, connecting the ductwork, and configuring the unit for either ducted or recirculating operation. The following sections will guide you through each of these stages in detail.
Step 1: Measuring and Preparing the Cutout
Cutout Dimensions and Clearance
For the COS-30IRHP, the cutout dimension is 30 inches, while the COS-6324EWH requires a 24-inch opening. It is crucial to ensure that the cutout matches the exact dimensions provided in the manufacturer’s specifications to avoid installation issues.
In addition to the cutout, the height clearance between the stove and the bottom of the range hood should be 27 to 30 inches for optimal performance. This height ensures that the hood is close enough to the cooking surface to effectively capture grease and steam but not so close as to interfere with cooking or create safety hazards.
Cabinet and Chimney Preparation
If the unit is being installed in a custom cabinet, the cabinet or chimney must be prepared in advance. The COS-6324EWH includes a seamless chimney set for cleaner lines and a more integrated look. For the COS-30IRHP, an insert mounting design allows the unit to be seamlessly integrated into the cabinetry.
For both models, the range hood height should be measured carefully to ensure that the final installation does not exceed ceiling height constraints. The height of the hood and duct cover must also be factored in during the planning phase.
Step 2: Mounting the Range Hood
Mounting Hardware and Tools
The installation process requires the following tools and hardware:
- Screwdriver
- Power drill
- Level
- Mounting brackets
- Wall anchors (if installing in masonry or concrete)
The COS-6324EWH is a wall-mounted model and must be securely fastened to the wall using the provided mounting brackets. The COS-30IRHP, being an insert model, is mounted within a cabinet and requires a secure fit to prevent movement or vibration during operation.
Before mounting, ensure that the unit is level using a bubble level. This step is critical to achieving both aesthetic and functional alignment.
Attaching the Range Hood
For the COS-6324EWH, the installation guide recommends the following steps:
- Secure the mounting brackets to the wall at the height of the cutout.
- Align the range hood with the brackets and secure it using the provided screws.
- Check that the unit is level and adjust as necessary.
For the COS-30IRHP, the unit is inserted into a custom cabinet and must be secured using the manufacturer’s mounting hardware. Ensure that the cabinet opening is properly sized and that the unit fits snugly without gaps.
Step 3: Connecting the Ductwork
Duct Type and Sizing
Both models are designed for ducted ventilation, which means the air is expelled outside the home. However, the COS-6324EWH can be converted to a recirculating system using the optional CFK6 carbon filter kit.
The ductwork must be made of rigid metal or aluminum, with a 6-inch diameter. Plastic ducts are not recommended due to the risk of warping or cracking under heat and steam.
The manufacturer emphasizes the importance of minimizing the number of elbows and the total length of the duct system. No more than three 90-degree elbows should be used, and each elbow should be separated by at least 24 inches of straight duct to maintain airflow efficiency.
Duct Installation Tips
- Use silver tape or high-quality duct tape to seal all joints and connections.
- Ensure that the duct is straight and unobstructed to prevent airflow restriction.
- If the duct is being installed through the roof or wall, apply caulking around the cap to prevent air leaks and water ingress.
- A backdraft damper is included with both models to prevent air from re-entering the kitchen after being expelled.
Step 4: Electrical Connections
Power Cord and Circuit Requirements
Both models are powered by a 120V/60Hz electrical supply and come with a 3-prong power cord for easy installation. The unit must be connected to a dedicated circuit to avoid overloading the electrical system.
Before connecting the unit to power, ensure that the circuit breaker is turned off to prevent electrical hazards. The installation guide also recommends that the unit be grounded according to local electrical codes.
Internal Electrical Components
The COS-30IRHP and COS-6324EWH both feature push button controls that manage the fan speed, lighting, and power. These controls are located on the front panel and are connected to the internal circuitry via a power clip.
If the unit is being installed in a recirculating mode (COS-6324EWH only), the carbon filter kit must be installed before connecting the unit to power. The filter kit is available for purchase separately and must be installed according to the manufacturer’s instructions.
Step 5: Installing the Filters
ARC-Flow Filters
Both models are equipped with washable stainless steel baffle filters known as ARC-Flow filters. These filters are designed to capture grease and cooking odors while allowing for high airflow. The filters are dishwasher-safe, which simplifies the cleaning process.
To install the filters:
- Insert the filters into the designated slots on the back of the range hood.
- Ensure that the filters are seated properly and do not obstruct airflow.
- Check that the filters are securely in place and do not rattle during operation.
Replacing or Cleaning Filters
Over time, the filters may become worn or clogged with grease. In such cases, they should be removed and cleaned in a dishwasher or with warm, soapy water. If the filters are damaged or no longer effective, they should be replaced with original equipment manufacturer (OEM) filters.
To replace or clean the filters:
- Turn off the unit and unplug it from the power source.
- Remove the filters by gently pulling them out from the rear of the unit.
- Clean the filters in a dishwasher or with warm, soapy water.
- Reinsert the filters once they are dry and secure them in place.
Step 6: Installing and Maintaining the LED Lighting
