Kaltis ULTRA LOW TEMPERATURE FREEZER User Manual - 3. General Recommendations
3. General Recommendations
The refrigeration system is designed to maintain ultra-low temperatures with safety in
a +32
o
C ambient environments, only when the freezer is used for its intended purpose
( storage).
CAUTION!
This unit is not a “rapid-freeze” device. Freezing large quantities or liquid, or
high-water content items will temporarily increase the chamber temperature
and will cause the compressors to operate for a prolonged period of time.
Improper use of the freezer may jeopardize safety or cause undue stress or
damage to the compressors.
Avoid opening the door for extended time periods because cold chamber air will
rapidly escape. Room air, which is higher in humidity, replacing chamber air may
cause rapid frost build-up in the chamber.
3.1 Environmental Conditions
This equipment is designed to operate in following conditions:
1.
Indoor use;
2.
Ambient temperature between 15°C and 32
o
C;
3.
Main supply voltage fluctuation not to exceed +10% to -10% of normal
voltage.
Initial Loading
When loading the unit with “pre-frozen” materials, the operating temperature set point
should not be set lower than the temperature of the “pre-frozen” material. Allow the
unit to operate at the set point for eight hours. The set point may than be lowered in
increments no greater than 10
o
C. Allow a stabilizing period of eight hours for every
ten degrees, until the desired set point is achieved.
CAUTION!
Failure to follow these procedures, or overloading the unit, may cause
excessive stress on the compressors any jeopardize user safety.
