Use only distilled or deionized water with a
resistivity between 50K  -CM and 1M  -CM and
a neutral pH. Using water outside this range will
void your warranty.
High concentrations of carbon dioxide can
cause asphyxiation. The use of CO
2
monitors
and alarms is recommended for areas where
CO
2
can collect.
The CO
2
gas supply should be 99.5% pure and
should not contain a siphon tube. Install a 2
stage gas pressure regulator with a maximum
adjustment of 25 psi. Inlet pressure must be
regulated to 15 psi.
Filling the Humidity Pan
To ensure proper operation, distilled or deionized water is required in the humidity pan.
Fill the humidity pan approximately half full of water. Place the pan directly under the
hinged airflow duct sitting on the bottom floor of the incubator to insure optimum
temperature and humidity response. The hinged airduct has “stops” designed into it to
ensure the pan is located in the ideal position. Slide the humidity pan back under the
duct until it hits the “stops”.
Connecting a CO
2
supply
The CO
2
supply should be 99.5% and not have siphon tubes. Regulate CO
2
pressure to
15 psi. CO
2
tank regulators are available to purchase through CARON customer
service. Once the cylinder regulator is installed, connect the outlet of the regulator to the
hose barb fitting using the tubing and clamps provided. An inline HEPA filter is provided
to remove any contaminants in the CO2 gas supply. Check the connections closely for
leaks.
