PERFORMANCE

WARNING

Electrical Shock Hazard

Plug into a grounded 3 prong outlet.

Do not remove ground prong.

Do not use an adapter.

Do not use an extension cord.

Failure to follow these instructions can result in death, fire, or electrical shock.

This wafﬂ e maker is designed for use with 120 V, 60 Hz only. It has a 3-prong grounded plug. To reduce the risk of electrical shock, this plug will ﬁ t in an outlet only one way. If the plug does not ﬁ t in the outlet, contact a qualiﬁ ed electrician. Do not modify the plug in any way.

A short power-supply cord is provided to reduce the risk resulting from becoming entangled in or tripping over a longer cord. Do not use an extension cord. If the power supply cord is too short, have a qualiﬁ ed electrician or service technician install an outlet near the appliance.

Service Preparation

WARNING

You can observe the performance of a wafﬂ e baker by establishing benchmarks on the performance seen on prior wafﬂ e bakers. Here is a list of performance parameters to observe.

EXAMPLE: Bake time: 3 minutes 30 seconds (3:30) Bake temperature: 350º F

■ Time to Bake Two Wafﬂ es – Measure the time needed to bake

two wafﬂ es (one cup batter each) on the two wafﬂ e plates. Longer baking times will produce darker, crispier wafﬂ es. For your ﬁ rst wafﬂ es, a good starting time is 3 minutes, 30 seconds. The baking time can be set in 15-second increments from a minimum of 2 minutes, 30 seconds to maximum of 5 minutes, 30 seconds.

■ Wafﬂ e Plate Temperature – Pre-heat wafﬂ e baker, then

measure the temperature on each wafﬂ e plate.
