1. INSTALL DUCTWORK AND ELECTRICAL WIRING
For a PKEX22 series power pack, either an external blower or in-line blower must be used. The PKEX22 series power pack must be installed with blower models ILB3, ILB6, ILB9, ILB11, EB6, EB9, EB12 or EB15 only. Other blowers cannot be substituted (blowers sold separately.)
If installing external or in-line blower, refer to instructions packed with blower and follow steps 1 to 6, 11 to 16, 18 and up of this manual.
Plan where and how the ductwork will be installed.
A straight, short duct run will allow the power pack to perform most efficiently. Long duct runs, elbows and transitions will reduce the performance of the power pack. Use as few of them as possible. Larger ducting may be required for longer duct runs.
Install proper-sized ductwork, elbows and roof or wall cap for the type of blower you are installing. Connect metal ductwork to cap and work back towards the hood location. Use 2” metal foil duct tape to seal the joints.
The minimum power pack distance above cooktop must not be less than 24’’. A maximum of 30” above cooktop is recommended for best capture of cooking impurities.
Distances over 30” are at the installer and users discretion.

3. PREPARE CUSTOM HOOD
!WARNING
•When building a custom hood, always follow all applicable construction codes and standards.
•Make sure the cabinet is capable of supporting its own weight and the weight of the power pack. Failure to do so may cause personal injury or damage to countertop or cooktop.
The custom hood must be constructed to fit the size and shape of the power pack. Proper structural support is required to accommodate the weight of the hood.
Start with the custom hood base, because its position will determine the height of the power pack. We recommend the base of the custom hood should be 3/4-inch thick plywood. If an optional custom hood liner will be installed, we recommend the sides and front of the custom hood to be 3/4-inch thick, assuming standard cabinet width . If the optional custom hood liner will not be installed, the custom hood side and front thickness is at the installer’s discretion.
Run power cable to installation location. Stub out a 4-foot length of electrical cable below the custom hood.

17. CALIBRATE IQ BLOWER SYSTEM™ (PK22 SERIES ONLY)
After the power pack is installed and wired, engage the calibration process (our Guaranteed 
Performance System Technology to ensure full-rated airflow is being delivered). Prior to 
calibration, ensure that all filters, light bulbs and duct system are installed.
CALIBRATION PROCESS
Hold the calibration button for 3 seconds; calibration button will light up and stay on for up to 13 minutes. The blower will start and begin the calibration process. When calibration is complete, one of two things will occur:
A. The blower turns off and calibration button light stays on = Successful calibration. Press the button to turn off the LED. NOTE: The LED will also turn off if you select any blower speed on the control.
B. The blower turns off and calibration button light blinks continuously = Too much |
|
restriction in the ductwork is preventing the IQ Blower System™ from achieving the |
CALIBRATION BUTTON |
rated airflow. The blower is automatically set to maximum intensity. |
CALIBRATION LIGHT |
NOTE: Common items that cause restrictions: restricted damper flap (backdraft |
HC0066 |
|
|
damper, wall cap, roof cap), too many elbows, duct size less than 80% of hood outlet, poor transition, use of flex ducting and/or |
|
crushed ducting. |
|
Three options are available if your power pack system has too much restriction:
1.Accept airflow as is. Press the calibration button to accept airflow as is. The IQ Blower System™ is now configured to its highest possible performance. The blinking calibration light goes out. NOTE: The LED will also turn off if you select any blower speed on the control.
2.Correct duct restriction, clear the original calibration data, and repeat the calibration process.
a.Correct the duct restriction.
b.Clear the original calibration data by holding calibration button for 10 seconds. The light will blink 3 times to confirm and the blower configuration will go back to default settings.
c.Repeat calibration process from the beginning.
3.Clear calibration data to reset power pack to default factory settings and achieve standard high pressure blower performance by holding calibration button for 10 seconds. The light will blink 3 times to confirm and the blower configuration will go back to default settings.

19. USE AND CARE
Hybrid Baffle Filters
The hybrid baffle filters should be cleaned frequently. Use a warm detergent solution. Wash more often if your cooking style generates greater grease — like frying foods or wok cooking.
Remove hybrid baffle filters by pushing them towards the back of power pack and rotating filters downward. Baffle filters are dishwasher safe. Allow filters to dry completely before reinstalling them in the power pack.
Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergent or as a result of local water conditions — but this will not affect filter performance. This discoloration is not covered by the warranty.
Internal Blowers Cleaning
Remove filters in order to access blowers. Vacuum blowers to clean. Do not immerse in water.
Power Pack Cleaning
Stainless steel cleaning:
Do:
•Regularly wash with clean cloth or rag soaked with warm water and mild soap or liquid dish detergent.
•Always clean in the direction of original polish lines.
•Always rinse well with clear water (2 or 3 times) after cleaning. Wipe dry completely.
•You may also use a specialized household stainless steel cleaner.
Don’t:
•Use any steel or stainless steel wool or any other scrapers to remove stubborn dirt.
•Use any harsh or abrasive cleansers.
•Allow dirt to accumulate.
•Let plaster dust or any other construction residues reach the power pack. During construction/renovation, cover the power pack to make sure no dust sticks to stainless steel surface.
Avoid when choosing a detergent:
-Any cleaners that contain bleach will attack stainless steel.
-Any products containing: chloride, fluoride, iodide, bromide will deteriorate surfaces rapidly.
-Any combustible products used for cleaning such as acetone, alcohol, ether, benzol, etc., are highly explosive and should never be used close to a range.

A. BLOWER DELAY-OFF BUTTON:
When blower is on, press the delay-off button to activate the delay-off function. The corresponding speed indicator LED will start flashing to indicate this function is activated.The fan will continue to operate for 10 minutes and will stop automatically.To cancel the delay-off function, press the blower delay-off button once again; the blower will then work in normal mode.
NOTE: The blower speed can be increased—or decreased—during delay-off mode without starting another 10-minute cycle.
B. ON BLOWER/SPEED CONTROL BUTTON:
Press this button to turn on the blower at the last selected speed. To change the blower speed, press the button again until the desired speed is obtained. Press and hold this button for 2 seconds to decrease the speed level down by one increment. Possible decreases are then: 4 to 3; 3 to 2; 2 to 1 and 1 to OFF.
NOTES: 1. Each time you press the speed control button, the speed changes by increments of 1 (e.g.: speed 1 to speed 2, to speed 3, and then speed 4). From the fourth speed, the speed goes down to level 1.
2.The last speed used is kept in memory so that when the unit is turned on, it will return to the last setting except the fourth, the next time the blower will be turned on, it will return to speed 3. The memorized speed level is also synced with the optional remote control.
HEAT SENTRY™
The power pack is equipped with a protective device that activates when excessive heat is detected inside the power pack. This device takes control of the blower and deactivates speed 4 for a 10-minute period and sets it on speed 3. During the Heat Sentry activation, only speed 3 can be used; the speed 4 button will flash while the speed 3 button will light up.
! WARNING
The HEAT SENTRY can start the blower during a range top fire or other excessive heat situations even if the power pack is turned off. In this case, it is impossible to turn the blower OFF with blower button. If you must stop the blower on PK22 series models: set the main power switch located behind the baffle filters in OFF position, if it is possible to do safely (see illustration below). For PKEX22 series models: do it from the main electrical panel.

UNLINKING PROCEDURE:
1- Turn lights and blower off.
2- Press and hold power pack button E for 10 seconds. Lighting LED indicator 2 will then blink 3 times as a completion feedback.
