AND
TROUBLE SHOOTING
8.1 CLEANING
Clean and disinfect with normal detergents. If hepatitis or HIV is suspected then use stronger
disinfectants.
8.2 TEMPERATURE
CONTROL/CALIBRATION
To be performed by a qualified technician only.
GENERAL INFORMATION
The working temperature is regulated by the temperature regulator T1 and the over
temperature protection by the sensors T2. When control, calibration of T1 and T2, their value
is compared to the value of an external precision thermometer. ( for example the KANMED
article Baywatch-01)
The sensor T2 can be adjusted through a hole in the bottom of the heating compartment.
The external control thermometer, with a precision temperature sensor, is to be placed
between two gel pads (GE-455015 or GE-255015) in the middle of the centre shelf.
Let the cabinet warm up properly (at least 12 hours if cold start) before attempting calibration.
8.2.1 TEMPERATURE REGULATION
INFORMATION ABOUT TEMPERATURE MEASUREMENT AND CALIBRATION
T1 is a powered microprocessor temperature regulator/indicator that has resolution of 1
°
C.
Corrections can be done through a series of pushing’s on the regulator buttons according to
the description below.
NOTE! To adjust the temperature T1 you have to have the door open. On older
cabinets equipped with a door switch the door switch S1 must be pressed with for
example some tape while you do the correction. Don’t forget to remove the tape when
you are finished.
PROCEDURE
Place the external control sensor as described under GENERAL INFORMATION above.
Start the warming and wait until the temperature is stable (at least 12 hours). Compare the
external control thermometer with the set temperature and if the deviation is bigger than +/-
1
°
C adjust as follows.
Old regulator type (700-0464)
1. Press UP and DOWN exactly simultaneously (only one beep may be heard, if you
don’t succeed- .repeat) and keep pressed for 5 sec until the indicator display shows
“PA”
2. Press UP or DOWN until the display shows “1”
3. Press SET and at the same time UP or DOWN to compensate the noted temperature
difference, one press gives a adjustment of 1
°
C.
1. For example: The display shows 42
°
C but the external control temperature shows
39
°
C. The difference is -3
°
C, to compensate this difference press three times on
DOWN button (the earlier value will drop with 3 degrees)
4. Store the new calibrated value by pressing UP and DOWN simultaneously (only one
beep may be heard, if you don’t succeed- .repeat)
5. Measure the temperature again and control that T1: s shown value compares to that
of the external thermometer.
If necessary dismount the locking of the door switch S1
