Figure 30
IMPORTANT: Static pressure in unit’s exhaust duct should be no greater than that shown in Figure 29. This can be measured with a manometer placed on the exhaust duct approximately 610 mm (2 feet) from the unit. Refer to Figure 29. All dryers connected to the main collector duct should be in operation when pressure is checked.
Installing an exhaust system does not eliminate the necessity of cleaning the dryer lint filter before each load. The dryer interior and the complete exhaust system should be cleaned periodically by a qualified service person to remove any lint
WARNING
To reduce the risk of electric shock, disconnect the electrical service to the unit before cleaning.
W476
A Backdraft Damper, Part No. 58786 (obtain locally), should be installed in a 102 mm (4 inch) diameter VERTICAL duct system only. This will prevent a backdraft when dryer is not in use, and will keep the exhaust air in balance within the central exhaust system.
