WARNING





VENTILATING HOODS:

• Clean Ventilating Hoods Frequently – Grease should not be allowed to accumulate on hood or filter.

• When flaming foods under the hood, turn the fan on.

SURFACE COOKING UNITS

• Use Proper Pan Size – This appliance is equipped with one or more surface units of different sizes. Select utensils having flat bottoms large enough to cover the surface unit heating element. The use of undersized utensils will expose a portion of the heating element to direct contact and may result in ignition of clothing. Proper relationship of utensil to burner will also improve efficiency.

• Never Leave Surface Units Unattended at High Heat Settings – Boil overs may cause smoking and greasy spillovers may ignite.

• Make Sure Reflector Pans or Drip Bowls Are in Place – Absence of these pans or bowls during cooking may subject wiring or components underneath to damage.

• Protective Liners – Do not use aluminum foil to line surface unit drip bowls or oven bottoms, except as suggested in the manual. Improper installation of these liners may result in a risk of electric shock, or fire.

• Glazed Cooking Utensils – Only certain types of glass, glass/ceramic, ceramic, earthenware, or other glazed utensils are suitable for rangetop service without breaking due to the sudden change in temperature.

• Utensil Handles Should Be Turned Inward and Not Extend Over

Adjacent Surface Units – To reduce the risk of burns, ignition of flammable materials, and spillage due to unintentional contact with the utensil, the handle of a utensil should be positioned so that it is turned inward, and does not extend over adjacent surface units.

• Do Not Soak Removable Heating Elements – Heating elements should never be immersed in water.

• Be sure you know which control pads operate each surface unit.

Make sure you turned on the correct surface unit.

OVEN

• Use Care When Opening Door – Let hot air or steam escape before you remove or replace food in the oven

• Do Not Heat Unopened Food Containers – Build-up of pressure may cause container to burst and result in injury.

• Keep Oven Vent Ducts Unobstructed – the oven vent is located above the left rear surface unit. this area could become hot during oven use. Never block this vent and never place plastic or heatsensitive items on vent

• Placement of Oven Racks – Always place oven racks in desired location while oven is cool. If rack must be moved while oven is hot, do not let potholder contact hot heating element in oven.

• Do Not allow aluminum foil or meat probe to contact heating elements.

GLASS/CERAMIC COOKING SURFACES

• Do Not Cook on Broken Cook-Top – If cook-top should break, cleaning solutions and spillovers may penetrate the broken cooktop and create a risk of electric shock. Contact a qualified technician immediately.

• Clean Cook-Top With Caution – If a wet sponge or cloth is used to wipe spills on a hot cooking area, be careful to avoid steam burn. Some cleaners can produce noxious fumes if applied to a hot surface.

DEEP FAT FRYERS:

• Use extreme caution when moving the grease kettle or disposing of hot grease.

COMPONENT TEST

Before testing any of components, perform the following checks:

NOTE:

1. The most common cause for control failure is corrosion on connectors.

Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures

2. ALL units in the first few days of use should be checked for mis-wiring or loose connections

1. All/tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms per-volt DC, or greater.

2. Check all connections before replacing components, looking for broken or loose wires, Failed terminals, or wires not pressed into connectors far enough.

3. Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.

!
