3.10 Filling the Water Jacket
There are two methods of filling the water-jacket.
a. Funnel Fill
b. Tap Fill
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 Fill
A funnel and vinyl tubing are contained in the accessories bag included with each
incubator.
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 3-3.
Attach the funnel into one end of the 3/8" I.D. vinyl tubing.
Remove the plastic protective cap from the fill fitting.
Attach the free end of the funnel tubing to the fill fitting.
Hold funnel above the level of the fill fitting and pour the water into the funnel until
the ADD WATER alarm light goes out. The water jacket holds about 13 gallons (49
liters) of water.
