The fire is small and contained in the area where it started.
The fire department is being called.
You can fight the fire with your back to an exit

Always leave safety grills and filters in place. Without these components, operating blowers could catch onto hair, fingers, and loose clothing.
The manufacturer declines all responsibility in the event of failure to observe the instructions given here for installation, maintenance,e and suitable use of the product. The manufacturer further declines all responsibility for injury due to negligence and the warranty of the unit automatically expires due to improper maintenance.

Description

The Cosmo Appliances Cabinet Range Hood COS-5U30 is engineered with durability and performance in mind. Its stainless steel body ensures long-lasting durability and resistance to corrosion. The range hood features a modern design that fits seamlessly into your kitchen cabinet, creating a sleek and integrated look.

The three-speed fan settings allow for flexible ventilation control, making it suitable for various cooking tasks. The LED lights provide clear illumination of the cooking area, enhancing visibility and safety. Additionally, the easy-to-clean filters make maintenance a breeze, ensuring optimal performance over time.

INSTALLATION REQUIREMENTS

PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY:

This Range Hood can be vented through the top or back. For ductless installation, install an Air Outlet Cap on the rear vent hole. If air will be vented, install the damper attachment on the side that the air will vent through (top or rear, shown in Fig. 2)
For optimal performance, the Range Hood must be installed 24” - 30” in height from the cooktop. (Fig. 1)
Electrical Requirements: Rated Voltage and Frequency:) 110-120V~ 60Hz. Motor Input Power: 90W

WARNING
ALL ELECTRICAL CONNECTIONS MUST BE IN ACCORDANCE WITH LOCAL CODES, ORDINANCES, OR NATIONAL ELECTRICAL CODES. IF YOU ARE UNFAMILIAR WITH METHODS OF INSTALLING ELECTRICAL WIRING, SECURE THE SERVICES OF A QUALIFIED ELECTRICIAN.

Sufficient air is needed for proper combustion and exhausting of gases through the chimney of fuel-burning equipment to prevent back-drafting. Follow the cooking equipment manufacturer's guidelines and safety standards such as those published by the National Fire Protection Association (NFPA), the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and local code. When cutting or drilling intoa wall or ceiling, do not damage electrical wiring and other hidden utilities. Ducted systems must always be vented outdoors.

PRE-INSTALLATION

Please read the instructions carefully. Unpack the Range Hood and check that all functions are working before installing.
Ensure that the voltage (V) and the frequency (Hz) indicated on the sticker match the voltage and frequency at the installation site.
Check that the area behind the installation surface to be drilled is clear of any electrical cables or pipes, etc.
The stainless steel surfaces of the Range Hood are very easily damaged during installation if scratched or bumped by tools. Please take care to protect the surfaces during installation.
Protect the cooktop surface below with plywood, or similar material, to prevent damage occurring during installation.
The manufacturer shall not be held liable for failure to observe all safety regulations.

IMPORTANT! READ BEFORE INSTALLATION!

You will need to set the Range Hood mode to either Ducted or Recirculating.

Remove Aluminum Filters
Locate Knob Settings located under the Motor (Fig. 3)
Rotate the lever to either Ducted or Recirculating mode.
If recirculating mode is chosen, install the vent cover on the rear vent hole.

If ducted mode is chosen, install the damper on the vent hole where the air will vent through (top or rear), and install the vent cover on the other vent hole (shown on Fig.2 of the previous page).

If using the recirculating mode, ignore this section.

Your venting system must vent to the outdoors either horizontally through the back wall (13) or vertically through the roof (14). (refer to Fig. 5/Fig. 6/Fig. 7).
For this range hood, use 5 in. round metal ductwork for the top -OR- use rectangular adapter / ductwork for the back. Connect to damper using HVAC aluminum tape.
The total duct length should not be more than 35 ft. Calculate the total effective length of the ductwork by using the table below. For each fitting use the table to see its straight duct equivalent.
Fasten all ductwork with sheet metal screws and tape all joints with certified HVAC tape.
If you must turn the path of the ductwork using elbows, keep the number of elbows to a minimum for best performance. Use no more than three 90 degree elbows. Ensure that there is a minimum of 25.6 in. of straight vent between each elbow. Use elbows as far away from the range hoods exhaust opening as possible.
Cap the exterior of the duct with a wall cap (15) or roof cap (16). Never use (4 in.) laundry-type wall caps. Use caulking to seal exterior wall or roof opening around the cap.
The venting system must have a damper. If the roof or wall cap has a damper, do not use the damper supplied with the range hood.

For recirculating mode, air will vent out of the front vent holes. (17 in Fig. 8)

WIRING DIAGRAM

CAUTION: SHUT-OFF POWER SUPPLY BEFORE INSTALLING. INSTALLATION WORK AND ELECTRICAL WIRING MUST BE DONE BY QUALIFIED PERSON(S) IN ACCORDANCE WITH ALL APPLICABLE CODES & STANDARDS, INCLUDING FIRE-RATED CONSTRUCTION.

CAUTION: HOOD MAY HAVE VERY SHARP EDGES; PLEASE WEAR PROTECTIVE GLOVES WHENEVER IT IS NECESSARY TO REMOVE ANY PARTS FOR INSTALLING, CLEANING OR SERVICING.

If cabinet bottom is recessed, we recommend installing wooden shims on cabinet bottom to make cabinet mounting area flush.

Drill two 8mm holes in position for plastic wall anchor (Part B) placement. (See above for placement location).
Tap plastic wall anchors securely into each of the drilled holes.
After Wall anchors have been tapped in place, Insert ST4*40 wood screws (part D), but leave 1/4” of the screw sticking out of the wall. (This will give your Range Hood something to hang onto).
If using recirculating mode: skip steps 4, 5a, 5c, 6a, 6c.
Take the hood unit along with the 5” Round Aluminum duct (Top) -ORrectangular adapter / ductwork (Back). Secure the round aluminum duct to the damper at the top or rear of the hood unit using HVAC Aluminum foil tape. (Skip this step for recirculating mode)
5a. If mounting to the wall only, drill a 5.25” round hole on the back wall above the hood, OR into the ceiling directly above the hood, or on the back wall centered with the rear vent hole of the hood. (Skip this step for recirculating mode)
5b. Lift the hood and hang the hood unit on the back wall using the screws drilled in Step 3. Once the hood is securely hung on the wall, tighten the screws from the interior of the hood after removing the aluminum filters.
5c. Pull rectangular adapter / ductwork through the newly drilled hole in the wall. Connect unit to power source. (Skip this step for recirculating mode)
6a. Drill a 5 - 1/4” Round Hole into the bottom of the cabinet. (skip this step for recirculating mode)
6b. Drill a 1 - 1/2” hole into the bottom of the cabinet for the Electrical Access hole according to the location of electrical wires shown on page 5 of this manual.
6c. Pull the round duct through the bottom of the new cabinet holes (skip this step for recirculating mode).
6d. Pull the electrical cord through the bottom of the cabinet holes.
Lift the hood and hang the hood unit on the back wall using the screws drilled in Step 3.
Once the hood is securely hung to the back wall, remove the aluminum filters from underneath the hood.
Drill four pieces of ST4*16 wood screws (Part E) into the bottom of the cabinet using the four screw holes at the top of the hood.
Once the hood is secured into the cabinet tighten the wood screws located in the back of the hood. Re-install the filters. Reconnect unit to power source.
