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.
