4.1 General
Notes
To ensure that chamber conditions remain as stable as possible, minimize the length of
time that the door is open. The magnetic door catches are specifically designed to make
door opening and closing as easy as possible. When you open the door, wipe off any
small drops of condensate that may have formed on the inner seal. This will avoid a
build-up of condensation.
If you are using the humidity tray for humidification, be sure to follow the indications
provided in Section 3.3.
4.2 Daily
Checks
1. Check that the temperature and CO
2
levels are reading within specification.
2. Check the reserve pressure in the CO
2
cylinder (normally 725 psi or 50 bar when
full). The design of the incubator ensures very low consumption of CO
2
: during
normal working conditions, a typical large cylinder should last approximately 12
months (frequent door openings will deplete the supply more rapidly, however). If
there is a significant drop at the cylinder pressure of 725 psi or 50 bar, it means that
the cylinder is almost empty and should be replaced. Making certain that there are
no leaks at any of the connections will ensure a greater lifetime to the CO
2
supply
and will help avoid accidentally running out of CO
2
.
3. Any spills in the chamber should be cleaned immediately to protect the stainless
steel surfaces.
4. Check the
DATALOGGER
screen for any alarms or events that may have occurred
overnight.
4.3 Monthly
Check
Remember that we recommend routine replacement of the water in the humidity tray,
and that you clean the tray at the same time.
1. If you are not changing the humidity tray water and cleaning the humidity tray
regularly, you should at least fill the humidity tray once a month. Do not, however,
exceed the maximum volume of 0.5 liters. Use warm water (~37.0°C) to ensure a
rapid return to optimum chamber conditions. After adding water, check that the
humidity tray is centered between the shelf rack supports.
