Whirlpool GXW7230DAS Electrical Requirements, For Non-Vented recirculating Installations

For Non-Vented (recirculating) Installations

If it is not possible to vent cooking fumes and vapors to the outside, the hood can be used in the non-vented (recirculating) version, by fitting a charcoal filter and the deflector. Fumes and vapors are recycled through the top grille. See the “Assistance or Service” section for information on ordering.

■	A 120 volt, 60 Hz., AC only, 15-amp, fused electrical circuit is
	required.
■	If the house has aluminum wiring, follow the procedure
	below:

A. Roof cap	A. Wall cap	A. Deflector
B. 6" (15.2 cm)	B. 6" (15.2 cm)	B. 6" (15.2 cm)
round vent	round vent	round vent

Calculating Vent System Length

To calculate the length of the system you need, add the equivalent feet (meters) for each vent piece used in the system.

Vent Piece	6" (15.2 cm) Round
45° elbow	2.5 ft
	(0.8 m)

90° elbow	5.0 ft
	(1.5 m)

Maximum equivalent vent length is 35 ft (10.7 m).

Example vent system

90 elbow		Wall cap
	6 ft (1.8 m)

2ft

(0.6 m)

The following example falls within the maximum recommended vent length of 35 ft (10.7 m).

1	- 90° elbow	= 5.0 ft (1.5 m)
1	- wall cap	= 0.0 ft (0.0 m)
8 ft (2.4 m) straight		= 8.0 ft (2.4 m)
Length of system		= 13.0 ft (3.9 m)

1.	Connect a section of solid copper wire to the pigtail
	leads.
2.	Connect the aluminum wiring to the added section of
	copper wire using special connectors and/or tools
	designed and UL listed for joining copper to aluminum.

Follow the electrical connector manufacturer's recommended procedure. Aluminum/copper connection must conform with local codes and industry accepted wiring practices.

■Wire sizes and connections must conform with the rating of the appliance as specified on the model/serial rating plate. The model/serial plate is located behind the filter on the rear wall of the range hood.

■Wire sizes must conform to the requirements of the National Electrical Code, ANSI/NFPA 70 (latest edition), or CSA Standards C22. 1-94, Canadian Electrical Code, Part 1 and C22.2 No. 0-M91 (latest edition) and all local codes and ordinances.
