START-UP OF UNIT
Use the following procedure to start trial operation or actual operation of the unit.
1.
Check the power switch is off, battery switch is off and sub-heater switch is off.
2.
Connect the power supply cord to the dedicated outlet with appropriate rating. Then turn on the
power switch.
3.
Turn on the battery switch.
Note:
The battery needs to be replaced about every 3 years. Contact Our sales representative or agent for
battery replacement.
4. The alarm buzzer sometimes operates. In this case, stop the buzzer by pressing the alarm buzzer
stop key (BUZZER).
5.
Set the chamber temperature to the desired temperature.
6.
Allow the chamber temperature to fall to the desired temperature. Check the chamber temperature
on the digital temperature indicator.
7.
Press the alarm test key (ALARM TEST) and check that the alarm lamp blinks and alarm buzzer
activates.
8.
Begin slowly placing items into the chamber to minimize the temperature rise.
CAUTION
Do not put too many warm articles into a freezer compartment before enough operating. Put items in a
few at a time after the freezer compartment temperature has cooled to at least -20
o
C.
Start-up of unit:
The unit is programmed to repeatedly turn the compressor on and off in order to make its startability
better when you start the unit at low ambient temperature (about 25
o C or lower). However, the unit
would start the operation without turning the compressor on and off repeatedly when you install the
cooled unit at high ambient temperature and it causes the unit would have the starting current running
with longer time.
The unit should be exposed to ambient temperature sufficiently, 4 hours at least to avoid the breaker from
trapping.
Operation after power failure
The memory (chamber temperature setting and alarm temperature setting) is backed-up by nonvolatile
memory. Accordingly, the freezer resumes the operation with setting before power failure.
CAUTION
The start-up after power failure is subject to adverse affection such as voltage drop because all electrical
appliance start to operate simultaneously. Always check the running status.
