4. CHECK OUT YOUR NEW FREEZER 

4.1 Lid Seal 

The gasket on the door has a magnetic strip to help door seal. 
Be  sure  to  keep  the  gasket  clean  and  free  of  debris.  Clean 
any  frost  that  may  build  up.  If  the  gasket  does  not  seal 
properly,  the  freezer  may  experience  problems  with 
maintaining temperature and excessive frost build up. 

 

4.2 Interior Compartment Temperature 

The  temperature  is  controlled  by  a  CAL  9500  digital 
temperature controller. When you first power up the freezer,  
the high stage compressor and fan will start and operate for 3 
to  6  minutes  before  the  low  stage  compressor  starts.    Pull 
down  to  minimum  temperature  will  take  from  3  to  6  hours, 
depending on ambient temperature and size of cabinet.  The 
high stage compressor runs 100% of the time.  The low stage 
compressor will cycle on and off to maintain the temperature 
of  the  controller  setting.    Set  the  control  to  the  desired  set 
point. To view the set point temperature, press the * and the 
UP  arrow  keys  together.  To  decrease  the  set  point 
temperature,  press  the  *  and  the  DOWN  arrows  keys 
together. 

Freezers  are  shipped  from  the  factory  with  the  indicating 
digital control programmed for proper operation. All but the 
temperature  settings  may  be  adjusted.  The  temperature 
sensor is a type 

“T”

 thermocouple located on the side wall of 

the inner-liner. 

4.3

 

Alarm  

The  Alarm  should  be  kept  in  the  “OFF”  position  until  the 
cabinet  temperature  has  reached  the  appropriate  setting.  
When  the  temperature  has  been  reached,  the  temperature 
alarm  should  be  switched  to  the  “ON”  position  and  is  now 
ready to operate. 
 
The Alarm is equipped with a time delay relay to prevent the 
alarm  from  going  off  every  time  the  door  is  opened.  This 
relay  can  be  adjusted  from  1  to  10  minutes.  This  delay  is 
factory set for 10 minutes. 
 
To adjust time delay relay: 

a)

 

Remove  screw  located  on  right  side,  middle  of 
instrument  panel  with  temperature  controller. 
Instrument panel will hinge open. Time delay has a 
dial and is located on lower right corner of electric 
box. 

b)

 

If you have a chart recorder:  Open glass door to get 
to  the  black  instrument  panel  with  chart  recorder. 
Remove  screw  located  on  right  side,  middle  of 
panel. Instrument panel will hinge open. Time delay 
has  a  dial  and  is  located  on  lower  right  corner  of 
electric box. 

  

NOTE:  It  is  recommended  to  keep  the  freezer  operating 
continually rather than turning the freezer off and on. 

4.4

 

Chart Recorder (Optional ) 

If your freezer has a chart recorder installed. On initial start 
up you must replace the round paper chart, connect the 9 volt 
battery and remove the black rubber cap on pen.  

WARNING: 

Do not lift the pen arm in order to slide a new 

chart under the pen or to remove the black rubber cap.  

To replace the paper chart: Press and hold the “change chart” 
button (#3) for approximately one second until pen begins to 
move to the left of the chart and then release the button. Wait 
until the pen has moved completely off the chart paper. To 
remove the chart paper, unscrew (counter-clockwise) the 
knob at the center of the chart paper. Remove old paper and 
position new one so that the correct time line coincides with 
the time line groove on the chart plate. Re-attach the knob, 
screw securely (by hand). (Do not over tighten. Over 
tightening can damage the gears in the chart motor gearbox 
assembly.) Press and hold change chart button (#3) again 
until pen begins to move back and then release button. 

To remove the black rubber cap at start up:  While you have 
arm moved off the paper for changing the chart, remove the 
rubber cap.
