8 Maintenance
8.1 Routine maintenance
8.1.1 General
To ensure that chamber conditions remain stable, minimize the length of time that the door is open. When
you open the door, wipe off any condensation that may have formed on the inner seal to avoid condensation
build-up.
If you are using the humidity tray for humidification, (see Using the humidity tray on p. 30).
8.1.2 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 (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 (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. Any spills in the chamber should be cleaned immediately.
4. Check the DATALOGGER screen for any alarms or events that may have occurred overnight.
8.1.3 Weekly checks
Refill the humidity tray with 1.5 - 2.5 liters of warm (~ 37.0 °C) distilled water. The use of warm water will
ensure a rapid return to optimum chamber conditions.
8.1.4 Monthly checks
We recommend routine replacement of the water in the humidity tray, and that you clean the tray at the
same time.
WARNING! Risk of injury to personnel or damage to equipment!
 Two stacked incubators should not be moved for maintenance or cleaning.
If you have two incubators stacked, the upper incubator does not have to be moved when you
are servicing the lower incubator.
Use distilled water only in the humidity tray. Use of any other types of water including
deionized water will cause corrosion inside the incubator.
