INCLUDED IN THE BOX:

The AprilAire 4232 Blue Orifice is a small but important nylon component which accurately meters the flow of water into your humidifier. If you determine that the rate of water flow to your AprilAire humidifier is too high or too low, check the orifice to determine if it has been damaged or dislodged. Replace the orifice if any defect is noted. Attempting to clean the hole in the orifice using pins and needles can enlarge and damage the hole.
To ensure that the correct amount of water is flowing to your humidifier for maintaining recommended humidity levels in your home, always use the correct orifice replacement part unique to your model humidifier. Blue Orifice 4232 is intended for a flow rate of 6GPH (gallons per hour).
Compatible Models listed below. Note: compatible with Model 700 manufactured prior to June, 2019 (check your Model 700 for the AprilAire label to locate the date code).
