7.3.4 Humidifier Atomizing Nozzle Maintenance (Option)
Clean-Out Plunger
Depress the clean-out plunger on the rear of each atomizer nozzle several times to clear out any
accumulated lime deposits from the nozzle orifice.
Note: Some atomizer systems have automatic clean-out nozzles with clean-out needles
operated by the compressed air supply, and do not have manual clean-out plung-
ers.
Disassembly and Cleaning
Use proper sized wrenches to remove the nozzle cap and retaining nut from the nozzle, and remove the
nozzle from the body, taking care not to bend or damage the clean-out needle. Retain the nozzle-to-body
gasket for reuse. Soak the parts in white vinegar to loosen any accumulated lime deposits. If necessary
clean parts with a non-metallic brush (such as a toothbrush) and/or probe (such as a toothpick).
Do not use a wire brush, pocket knife, or other metallic tool.
It is very easy to damage the orifice shape and/or size and produce
distorted spray patterns or excess flow.
After cleaning, rinse the parts with clean water. Reassemble the nozzle to the body reusing the gasket.
Replace the nozzle cap and retaining nut.
