4.1 General Notes
To ensure that chamber conditions remain as stable as possible, be sure to 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). 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. Ensuring
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. 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 1.5 (or optional 2.5) liters. Use warm
water (approx. 37.0°C) to ensure a rapid return to optimum chamber conditions.
After adding water, check that the humidity tray is pushed fully back against the
rear wall.
