4.3 General Recommendations
Avoid opening the door for extended time periods. Room air, which is higher in
humidity, will replace chamber air and cause frost to develop. Allowing the door to remain
open for extended time periods will cause the chamber to "warm-up", putting undue stress
on the compressors.
This unit is not a "quick-freeze" device. Freezing large quantities of
liquid, or high-water content items, will temporarily increase the
temperature and will cause the compressors to operate for a prolonged time
period. Damage to the compressors may result and product safety may be
jeopardized.
