(4) Maintenance Tips & Installation
visually inspect temperature and CO2 display to make sure they match the set points.
Record these temperatures.
1 Check CO2 with independent analyzer, take two readings, record this
reading. If reading is more
than .5% from set point. Do not enter unit for one hour and take two more readings. If still
than .5% check manual factory recommendations. Some users wait until the next day.
2 Check display
temperature with internal thermometer located in the geometric center of the chamber.
3 Inspect humidity pan
and to make sure pan is at proper level.(If applicable)
Check humidity display and record.
4 Check high

5 Check low pressure gauge on CO2 tank regulator. See manual for
(most manufactures recommendations are between 15-20 psig.)
6 Check to make sure
not material is stored on top of unit. Many manufactures do not recommend
the storage of on top because of heat disapation.
Six Month Check:
1 Check all filters for discoloration. Replace if discolored.
Check gas lines and CO2 regulator for leaks.
3 Check air flow or fan blade for rotation and discoloration.
This depend so on manufacturers and models.
4 Check CO2 tank switcher for proper operation.
Yearly Inspections & Calibrations:
1 Use factory procedures to calibrate CO2 and
Temperature. Most manufacturers recommend a trained
technician to preform component level reclaibration. See user manual.
Inspect power cord for wear. This includes cracks, exposed wires and burn marks on power plug.
interior and autoclave all removalble parts if so desired. See manual for manufactors
recommendation. Do not use Purex,
Clorox, strong alkaline or caustic on stainless steel. Stainless
Steel is corrosion-resistant but not corrosion-proof.
These can cause corrosion or pitting in
4 Check all filters for discoloration. Replace
Check air flow or fan blade for rotation and discoloration. This dependso on manufacturers and models.

Common over looked items on installation:
Follow factory recommendations (see manual)
1 Verify proper voltage.
2 Do not install
unit in direct sun light or direct path of heating or air conditioning vents.
Both of these can cause temperature control
problems or condensation problems.
3 Make sure you install unit to insure technician can service contorl panel.
Check the level of the unit before filling with water. Check both the out side cabinet and
