RECOMMENDED SHUTDOWN PROCEDURE
TO MINIMIZE RISK OF FREEZING OR CORROSION
When high humidity or moisture is present in an air piping system, condensation of water can occur after the blower is shut
down and the blower begins to cool. This creates an environment favorable to corrosion of the iron internal surfaces, or in cold
weather, the formation of ice. Either of these conditions can close the operating clearances, causing the blower to fail upon
future start-up.
The following shutdown procedure outlined below minimizes the risk of moisture condensation, corrosion and freezing. Care
must be taken so as not to overload or overheat the blower during this procedure.
1. Isolate the blower from the moist system piping, allowing the blower to intake atmospheric air. Operate the blower under a
slight load allowing the blower to heat within safe limits. The heat generated by the blower will quickly evaporate residual
moisture.
2. For carpet cleaning applications, after the work is completed, simply allow the blower to run a few (3-5) minutes with the
suction hose and wand attached. The suction hose and wand will provide enough load to the blower to evaporate the
moisture quickly.
3. For extended shutdown, inject a small amount of a light lubricating oil such as 3-in-One ® or a spray lubricant such as WD-
40 ® into the inlet of the blower just prior to shutdown. The lubricant will provide an excellent protective coating on the
internal surfaces. If using a spray lubricant, exercise care to prevent the applicator tube from getting sucked into the blower.
The applicator tube will damage the blower, most likely to the point that repair would be required.
