12.5 Gasket Maintenance
Periodically check the gaskets around the door for punctures or tears. Leaks are indicated by condensation or frost which
forms at the point of gasket failure. Make sure that the cabinet is level (refer to
Section 7.1.1
for leveling information).
Keep the door gaskets clean and frost free by wiping gently with a soft cloth.
To check the door seal, complete the following steps:
1. Open the door.
2. Insert a strip of paper (a couple of inches wide) between the door gasket and the cabinet flange and close the door.
3. Slowly pull the paper strip from the outside. You should feel some resistance.
4. Repeat this test at 4-inch intervals around the door. If the door does not seal properly, replace the gasket.
12.6 Alarm Battery Maintenance
Have a certified technician replace the alarm battery every twelve months at most or when the alarm is active.
The part number for a replacement battery is 322533H01.
12.7 Preparation for Storage
If the unit is going to be stored in an off condition, allow the unit to warm up and dry out with the door open before moving
into storage.
12.8 Cleaning the Unit (Chromatography Refrigerators)
The refrigerator is designed to be cleaned using a mild detergent (such as Lysol® wipes (non-aerosol) or Formula 409®) and
water. Lightly spray the interior storage components and wipe them dry with a soft cloth or spray the cloth first and then
wipe interior surfaces. Do not spray directly on the center outlet column. Use a damp cloth to clean around the outlet.
Use of other cleaners may contain chemicals that will turn off power to the outlet. If this occurs, continue to clean the
refrigerator and leave the doors open for approximately 5 minutes to allow any vapors to exit the refrigerator. In the event that
the outlet power turns off due to chemicals, the red light will illuminate and the user will need to manually reset the safety
circuit using the “Switch Manual Reset Chromatography” at the back of the unit before power is restored. Toggling this switch
off then on will restart the safety system and the green light should illuminate after approximately 4 minutes. If the light
repeatedly changes from red to green or the red light stays illuminated, ensure there are no chemical vapors present in the
refrigerator and reset the system. If this continues, please contact Customer Service.
12.9 Replacing Sensor (Chromatography Refrigerators)
The sensor needs replacement if the temperature goes below freezing in the cabinet. Use system alarms to ensure the temperature
inside the unit is always above 0°C. If exposed to freezing conditions the sensor shall be replaced.
If the display shows an error and sounds an alarm (in case of a control, defrost, bottle or ambient probe failure), the sensor
needs to be replaced.
12.10 Sensor Maintenance (Chromatography Refrigerators)
The sensor shall be replaced every five years by a trained service provider
