EXTERIOR OR IN-LINE BLOWER SELECTION

CAUTION: Either an exterior blower or in-line blower may be used with this hood. The KEX273 hood must be installed with blower models EB6, EB9, EB12, EB15, ILB3, ILB6, ILB9, or ILB11 only. Other Blowers cannot be substituted (Blowers sold separately). The blower must be UL listed for Canadian and U.S. use, and evaluated for use with solid state speed control, rated 120V, 60 Hz, 6.0 A max.

INSTALL THE DUCTWORK

NOTE: To reduce the risk of fire, use only metal ductwork.

1. Choose the location where the Exterior or In-Line Blower will be mounted. See

illustrations below for mounting location suggestions and restrictions.

2. A straight, short duct run will allow the hood to perform most efficiently.

3. Long duct runs, elbows and transitions will reduce the performance of the

hood. Use as few of them as possible. Larger ducting may be required for best performance with long duct runs.

4. After the Exterior or In-Line Blower has been installed, connect round metal

ductwork and work back towards the hood location. Use duct tape to seal joints between ductwork sections.

5. An 8” round to 10” round transition (Model 414) is required. For best air

performance, install the transition as close to the range hood as possible.

MAINTENANCE

Proper maintenance of the Range Hood will assure proper performance of the unit.

Grease Filters

The grease filters should be cleaned after every 30 hours of operation. This range hood has an operation timer which will alert you after every 30 hours of use by lighting a red LED above the “blower speed 0-1 button”. Use a warm detergent solution. Grease filters are dishwasher safe.

To take off the grease filters: at the handle, push the stop inwards and pull the filters downwards.

Hood Cleaning

Stainless steel is one of the easiest materials to keep clean. Occasional care will help preserve its fine appearance.

Cleaning tips:

O Hot water with soap or detergent is all that is usually needed. O Follow all cleaning by rinsing with clear water. Wipe dry with a clean, soft cloth

to avoid water marks.

O For discolorations or deposits that persist, use a non-scratching household

cleanser or stainless steel polishing powder with a little water and a soft cloth.

O For stubborn cases, use a plastic scouring pad or soft bristle brush together

with cleaser and water. Rub lightly in direction of polishing lines or "grain" of the stainless finish. Avoid using too much pressure which may mar the surface.

O DO NOT allow deposits to remain for long periods of time. O DO NOT use ordinary steel wool or steel brushes. Small bits of steel may

adhere to the surface causing rust.

O DO NOT allow salt solutions, disinfectants, bleaches, or cleaning compounds

to remain in contact with stainless steel for extended periods. Many of these compounds contain chemicals which may be harmful. Rinse with water after exposure and wipe dry with a clean cloth.

Painted surfaces should be cleaned with warm water and mild detergent only.

The blower on-off / speed 1 switch turns the blower on to its lowest running speed. To turn OFF the blower, push in and hold this blower switch for approximately 2 seconds.

LIGHT

SWITCH

The blower speed 2 switch turns the blower on to medium-low running speed. Pressing this switch a second time sets a timer which keeps the blower operating at this speed for 10 minutes. The LED will blink during this time and the blower will shut off automatically.

The blower speed 3 and blower speed 4 switches operate the same as blower speed 2 switch except: Blower speed 3 is medium-high and blower speed 4 is high.

After every 30 hours of operation, the LED above the “blower speed 1 switch” will be illuminated (RED) and blink for 30 seconds after turning off the blower. This is a reminder to clean the grease filters. Once the grease filters are cleaned and installed, press in and hold the “light switch” button for approximately 2 seconds during the blink of the LED.

HEAT SENTRY™

Your hood is equipped with a HEAT SENTRY™ thermostat. This thermostat is a device that will turn on or speed up the blower if it senses excessive heat above the cooking surface.

1) If blower is OFF - it turns blower ON to HIGH speed.

2) If blower is ON at a lower speed setting - it turns blower up to HIGH speed. When the temperature level drops to normal, the blower will return to its original setting.

WARNING The HEAT SENTRY thermostat can start the blower even if the hood is turned OFF. When this occurs, it is impossible to turn the blower OFF with its switch. If you must stop the blower, do it from the main electrical panel.
