CAUTIONS FOR USAGE 
G) If the  unit 
is 
unplugged  or the  power to  the  unit 
is 
interrupted, 
do 
not restart the unit for at least 5 minutes. 
This protects the compressor. 
®  This  inner  cabinet 
is 
refrigerated 
by 
the  forced 
circulation  of cooled  air inside  the  chamber. 
Ensure 
that the intake and exhaust vents are not blocked. 
@  Adequate  space  should 
be 
provided  between 
the 
items inside the unit to allow air circulation. 
@  Never  store  corrosive  materials  such  as 
acid 
or 
alkali  unless  the  container 
is 
completely  sealed 
up. 
Corrosion may lead to failure 
of 
the unit 
in 
time. 
@ Once  the  chamber temperature  has  stabilized, 
put 
the  items  into  the  chamber 
in 
small  batches 
to 
minimize the temperature increase. 
®  Fix  the  shelves  securely.  Place  items 
on 
the 
shelves 
and 
leave  a  space  between  the  walls  of 
the 
cabinet 
and 
the  contents 
to 
allow  air circulation. 
Do 
not place items 
on 
the floor of the chamber. 
(J) 
When 
the 
power plug-in  the  unit,  the  fan  does 
not 
always operate  immediately.  After a few minutes, 
the 
fan  operates properly. 
® For  some  time  after 
the 
unit  has  been  started,  or 
when the ambient temperature 
is 
fairly high,  the cabinet 
walls  may  heat 
up. 
This  does  not  indicate  a 
malfunction.  It  indicates  that  the  dew 
preventative/power  economy  function 
is 
performing 
satisfactorily.  Hot  gases  are  piped  from  the  motor 
compressor  along  the  front  edges  of the  cabinet  to 
prevent dew condensation. 
@ If condensation  forms 
on 
the  front  glass 
or 
frame 
surface, wipe it off with  a soft,  dry cloth. 
@l 
Do 
not clean  the  unit with  scrubbing  brushes,  acid, 
thinner,  solvents,  powdered soap,  cleanser 
or 
hot water. 
These agents 
can 
scratch the  paint or cause  it to  peel. 
Plastic  and  rubber  parts 
can 
be 
easily  damaged  by 
these  materials,  especially  solvents.  When  a  neutral 
detergent 
is 
used 
to 
clean 
the  unit,  rinse  thoroughly 
with a cloth soaked 
in 
clean 
water. 
!TIl 
If 
an 
instrument requiring  a  power  source  is  to  be 
placed  inside the cabinet,  the cable 
can 
be 
led through 
the  access  port 
on 
the 
left  hand  side  of the  cabinet. 
After installation,  a  rubber cap  should 
be 
used 
to 
seal 
the  access 
port. 
Failure  to 
do 
this 
can 
affect  the 
temperature  uniformity  inside  the  cabinet  and  lead  to 
condensation 
on 
the outside of the access port.

START-UP OF UNIT 
The following procedure should 
be 
adhered to for initial start-up and continuous operation. 
<D 
Connect unit to dedicated power supply.  Do not put 
any 
product 
in 
the unit 
at 
this time. 
® When the  power 
is 
initially applied, the audible alarm 
may sound.  Set the BUZZER switch to OFF to silence 
the alarm. 
@ Set the desired temperature. 
Handling 
of 
the containers 
@ Check that the chamber temperature has reached to 
the desired temperature. 
@ 
When 
you  are  satisfied  that  the  unit 
is 
working 
correctly, begin slowly placing product into the chamber 
to minimize the temperature rise. 
Arrange containers not to disturb air circulation 
in 
the unit.  Disturbance 
of 
air circulation  may cause freeze 
of 
containers or incline 
of 
temperature. 
<D 
Air 
intake 
vent 
Avoid  the  disturbance 
of 
air circulation 
in 
the  unit 
by 
containers.  Disturbance 
of 
air circulation may causes 
freeze 
of 
containers or incline 
of 
temperature. 
® 
Air 
exhaust 
vent 
Do 
not disturb the exhaust air port 
by 
putting containers 
near the exhaust air port.  Containers near the exhaust 
air  port  may  freeze  when  the  unit  runs  with  low 
temperature (less than 
5°C). 
Note: 
Never store the  material  of corrosive  such 
as 
acid  or 
alkaline 
of 
which container is not sealed 
up 
completely. 
It may cause poor cool 
by 
refrigerant leakage resulted 
from corrosion 
of 
the evaporator.

There are two types 
of 
defrost cycles present 
in 
this blood bank refrigerator, and both cycles occur automatically. 
1.  Cycle 
defrost 
To keep the temperature stable inside the chamber, the 
refrigeration  compressor 
is 
cycled 
on 
and  off.  During 
the  "off'  periods 
any 
frost which  has  accumulated  on 
the  refrigeration  coils 
is 
melted 
by 
energizing  a  small 
heater,  this  will  not have any discernable effect on  the 
chamber temperature. 
11 
2. 
Forced 
defrost 
When  ambient  humidity 
is 
high,  or a  large  amount 
of 
damp  product 
is 
being  stored  inside  the  refrigerator, 
there  is  a  possibility  that  cycle  defrost  may  not  be 
enough  to remove  all 
of 
the  frost 
on 
the  refrigeration 
coils.  In  this  case,  a  forced  defrost  cycle  will  be 
initiated.  While  the  unit 
is 
operating  under a  forced 
defrost cycle, the defrost lamp on  the control panel will 
be  lit.  Once  the  forced  defrost  cycle 
is 
complete, 
normal  operation  will  resume.  The  chamber 
temperature rises to about 
10°C 
during the defrosting.
