CONNECTING DUCT WORK TO DIL1200 INLINE FAN USE AND CARE Two duct clamps part number 001377-000 are included with this unit and are intended to simplify fan installation and isolate fan vibration from the rigid metal duct. Note: The duct clamps are convenient in installations where regular removal of the fan in necessary for inspection and cleaning. 8mm neoprene pad The built in hanger tab of the duct clamps are not intended to support the weight of the inline fan. The inline fan should be supported with the integral brackets of the inline fans. If special supports are required in anticipation of earthquakes the duct clamps that are supplied with the DIL1200 are not intended to meet these requirements. To minimize vibration, leave a 1/4" gap between the inline fan collars and rigid duct. Tighten the two screws until the fan and duct are snugly attached. Disconnect electrical power supply and lock out service panel before cleaning or servicing this unit. CLEANING Periodic inspection and cleaning is recommended. The frequency of inspection and cleaning should be adjusted according to the type and amount of cooking. The interior of the fan can to accessed by removing the duct clamp and gently moving the duct work away from the inlet of the fan. If excess build up is present it should be removed from the interior of the fan and from the impeller of the fan. MOTOR LUBRICATION The motor is permanently lubricated. Do not oil or disassemble motor. The duct work at the inlet of the inline fan is to be connected to the range hood. The duct work at the out box of the inline fan is to be connected to a roof or wall cap. A inline butterfly damper part number PV300006 is included with the DIL1200. The damper can be installed anywhere in the duct system. Damper must be installed so that the airflow direction will open the butterfly blades. Mounting the damper in an inverted position may prevent the blades from closing completely. The preferred installation position is vertical as shown below.
