DRAINING OF WATER JACKET, 460 SERIES:
With the use of distilled water, periodic draining and refilling of the
water jacket is not necessary. In the event the incubator is moved however,
the water jacket should be drained. The drain is located at the left front
bottom of the cabinet and is opened when the 1/4” adapter fitting (supplied
with the unit) is inserted.
•
Disconnect unit from electrical power.
•
Connect the barbed end of the adapter fitting to appropriate-sized
tubing. Place the other end of the tubing in a sink, floor drain or in an
adequately sized receptacle (bucket or large pan). Connect the
other end of the fitting to the incubator.
•
Leaving drain tube connected, flush with distilled water to remove
any possible deposits within the water jacket.
•
Disconnect the adapter fitting and add 500 ml of quality rust
preventative such as ethylene glycol.
Fill water jacket per instructions on page 32.
HUMIDIFICATION (if required):
As a preventive measure against mineral deposit build-up,
USE ONLY
DISTILLED WATER
. Mineral deposits can affect the CO
2
control. Check water
level at intervals to maintain conditions of humidity required for work being done.
To humidify the chamber atmosphere, use the stainless steel pan which is
included, pouring distilled water into it. DO NOT flood the bottom of the chamber
with water.
While the addition of a fungicide to the water will assist in controlling
contamination, it may also affect the results of experiments conducted with cells,
viruses and other materials. These factors should be taken into account when
deciding to use or not to use a fungicide.
