DocumentDocumentCleaning Instructions for Humidifiers with HydroCoreTM Hard Water Installation* Annual replacement of the orifice and cleaning of the valve is required to maintain optimal performance. Soft or Softened Water Installation* Replace the orifice and clean the valve every 3 years or as needed based on usage. *To determine water connection, trace the water inlet (L) back to the water source to see if it is connected to a softener or contact your service technician. Itchy skin, poor soap lather, and mineral residue or buildup on faucets or appliances are signs of hard water. WARNING: Take note of humidifier control setpoint and turn dial to off position before starting. 1. Remove cover (A) by depressing latch (B) and pulling away from base (C). Remove HydroCore (D) then brush away any mineral deposits from the base. 2. Plug the drain port (E) or raise the end of the flexible drain line (F) above the valve and secure to create a trap. 3. Pour white vinegar into the valve cup (G) up to the clean line (H). Soak for up to 30 minutes. 4. Use a small plastic bristle brush to remove buildup in the valve cup then drain vinegar solution. Flush with water. 5. Replace the rubber seal cap (I) and orifice (J) assembly (PN: 70000037). See Orifice Replacement Instructions. 6. If applicable, remove the drain line and flex it to loosen any mineral deposits or blockages then flush with water. If it does not clear, replace it. Reattach drain line, ensuring it has a constant downward slope and is not flattened or blocked. 7. Install fresh HydroCore and test to confirm proper function.
