Section 5
Maintenance
The design of the growth chamber is such that periodic maintenance is
kept to a minimum. No lubrication is required. The following paragraphs
cover the few minor procedures necessary for continuous operation.
Warning
Turn off power switch and unplug line cord from power source
before starting any maintenance procedure.
s
If the chamber needs to be cleaned, a mild soap and water solution, or
bicarbonate of soda (1tbsp./gallon of water), is recommended.
When the growth chamber is used frequently below ambient temperatures,
or in any manner that increases moisture buildup within the chamber, an
appropriate defrosting schedule must be determined. Defrosting is
accomplished by turning the growth chamber off for 24 hours. Moisture
will collect in the drip pan beneath the growth chamber.
1) Overcharging a refrigeration system can cause excessive system pressure
and can be dangerous.
2) The compressor terminal protective cover must be properly in place
before applying electric power to the compressor.
3) Caution should be exercised by service personnel when servicing
refrigeration system.
4) Service should be performed by a certified refrigeration technician
only.
