Whirlpool YUMV4084B Dimension Guide

PRODUCT MODEL NUMBERS

VENTING REQUIREMENTS

Electrical Requirements Required:

●

A 120 volt, 60 Hz, AC only, 15- or 20-amp electrical supply with a fuse or circuit breaker.

Recommended:

●

A time-delay fuse or time-delay circuit breaker.

●

A separate circuit serving only this microwave oven.

Microwave Hood Combination

This section is intended for architectural designer and builder/contractor reference only.

NOTES:

●

If installing for recirculation, venting must be routed up and out through an exhaust register (not provided) in a kitchen soffit. A charcoal filter kit (not provided) should be used. See “Assistance” section for information on ordering.

●

Vent materials needed for installation are not provided with microwave hood combination.

●

We do not recommend using a flexible metal vent.

●

To avoid possible product damage, be sure to vent air outside, unless using recirculation installation. Do not vent exhaust air into concealed spaces, such as spaces within walls or ceilings, attics, crawl spaces or garages.

For optimal venting installation, we recommend:

●

using roof or wall caps that have back draft dampers

●

using a rigid metal vent

●

using the most direct route by minimizing the length of the vent and number of elbows to provide efficient performance

●

using uniformly sized vents

●

using duct tape to seal all joints in the vent system

●

using caulking compound to seal exterior wall or roof opening around cap

●

for optimal hood performance, do not install 2 elbows together

If rectangular to round transition is used, be sure there is at least 3" (7.6 cm) of clearance between the top of the damper assembly and the transition piece. See “Rectangular to Round Transition” illustration.

Rectangular to Round Transition

NOTE: The minimum 3" (7.6 cm) clearance must exist between the top of the damper assembly and the rectangular to round transition piece so that the damper can open freely and fully.

Recommended Standard Fittings

The following length equivalents are for use when figuring vent length. See the examples in “Recommended Vent Length.”

Recommended Vent Length

A 3¹⁄₄" x 10" (8.3 x 25.4 cm) rectangular or 6" (15.2 cm) round vent should be used.

The total length of the vent system including straight vent, elbow(s), transitions and wall or roof caps must not exceed the equivalent of 140 ft (42.7 m) for either type of vent. See “Recommended Standard Fittings” section for equivalent lengths.

For best performance, use no more than three 90° elbows. To calculate the length of the system you need, add the equivalent lengths of

each vent piece used in the system. See the following examples:

If the existing vent is round, a rectangular to round transition piece must be used. In addition, a rectangular 3" (7.6 cm) extension vent between the damper assembly and rectangular to round transition piece must be installed to keep the damper from sticking.

PRODUCT DIMENSIONS

CABINET OPENING DIMENSIONS

NOTE: The grounded 3 prong outlet must be inside the upper cabinet. See

“Electrical Requirements” section.

*Measure from the front edges of the side cabinets. **For installation with stainless steel filler panel. NOTE: To avoid stress on the power cord, a minimum of 1¹⁄₂" (3.8 cm) must exist

between the top surface of the microwave oven’s upper component housing and the bottom of the upper cabinet.
