Aprilaire 620AK FAQs
Does the Aprilaire 620AK come with a digital humidistat and the HydroCore?
Yes. The Aprilaire 620AK ships with the Model 60 automatic digital control, one HYDROL L HydroCore cartridge, a 4010 24-volt transformer, a 4001 saddle valve, an owner's manual and an installation template, according to Aprilaire's 620A listing. The Model 60 adjusts the humidity target to the outdoor temperature in automatic mode and also offers a manual mode.
How large a home can the Aprilaire 620AK humidify?
Aprilaire rates the 620AK's Model 620 humidifier at 18 gallons per day, enough for homes up to 5,300 square feet. It is a bypass, duct-mounted evaporative unit that runs on 24 volts and connects to your water supply and a drain, so have a licensed HVAC technician install it on your furnace ductwork.
What is the difference between the Aprilaire 620AK and 620MK?
The Aprilaire 620AK and 620MK use the same 18-gallon-per-day Model 620 bypass humidifier and HydroCore cartridge; the difference is the control. The 620AK includes the Model 60 automatic digital control, which adjusts to outdoor temperature, while the Aprilaire 620MK includes the Model 4655 manual control, which you adjust yourself.
What replacement water panel does the Aprilaire 620AK use?
The Aprilaire 620AK uses the HYDROL L HydroCore, a one-piece cartridge that combines the water panel, distribution tray, scale control insert and feed tube. Aprilaire says to replace the HydroCore every 12 months, and its HYDRLH hard-water kit adds a replacement orifice for homes with hard water. PureFilters carries the Aprilaire HYDROL cartridge.
How much water does the Aprilaire 620AK save compared with the Aprilaire 600?
Aprilaire says the 620AK's Model 620 humidifier produces 55% less wastewater than the Aprilaire 600, because its recirculation valve reuses water across the HydroCore instead of sending it all to the drain. Aprilaire estimates savings of up to 4,650 gallons of water per year versus previous models at rated capacity over a five-month season.
