Maintaining Your DH

DH Chamber
The chamber maintenance is up to the discretion of the owner and the extent of cleanliness and sterility desired.
The shelves and bracket supports are all removable and autoclavable.
The interior should be wiped down with an appropriate disinfectant such as 70% ISOPROPYL ALCOHOL or equivalent.

Note: DO NOT USE ANY CHLORINATED OR HALOGEN MATERIALS IN THE CHAMBER.
SUCH MATERIAL IS HARMFUL TO THE POLISHED STAINLESS STEEL.
The humidity pan should also be sterilized and the water changed regularly to assure sterility.
A small amount of copper sulfate may be added to the humidity pan to inhibit bacterial growth.

10.1 Chemical Decontamination of the Incubator Chamber

To chemically decontaminate NuAire Incubator inner chambers, users may use the traditional formaldehyde or Chlorine
Dioxide in gas form, or Vapor Phased Hydrogen Peroxide.
All three of the chemicals are compatible to all parts within NuAire Incubator chambers.
The incubator should be turned off during these procedures
Note: As stated previously, the chamber and components can also be wiped down with a
70% solution of Isopropyl Alcohol for cleaning and decontamination.

10.2 Shutting down the Incubator

Prior to shutting down the Incubator open the inner and outer doors and remove the water pan.
Leave doors open for at least 5 minutes prior to shutting it off.
This will purge the chamber, circulating system and the sensors of humidity that could condense and cause faulty
readings when the Incubator is turned back on.
Be sure to empty the water pan prior to putting it back into the chamber if the Incubator is going to be shut off for any
length of time.
