4.10 FILLING THE WATER JACKET
There are two methods of filling the water-jacket.
a. Funnel Fill Method
b. Tap Fill Method
Caution: Purity of the distilled water used in the water jacket and humidifier must
be within the 50K ohm to 1 Meg ohm range to protect and prolong the life
of the stainless steel water jacket. The use of tap water or distilled water
outside of the specified range will decrease the operating life of the unit
and will void the warranty.

A funnel and vinyl tubing are contained in the accessories bag included with each
incubator.
1. Verify that the water jacket drain valve on the bottom of the incubator frame is
closed. The valve is located behind a protective metal cover and will require two
screws to be removed. The valve is closed when the valve knob is turned vertical.
Refer to the illustration in Figure 4-4.
