cabinet’s actual operation compared to control measurements by
independent temperature measuring systems.
The A-sensor is used to manage the cabinets refrigeration system, and
is also the reference sensor for the display and alarms.
The A-sensor is oset if the actual temperature in the cabinet does not
match the setpoint, despite taking the hysteresis into consideration.
Oset of A sensor is named “CA”.

Practical example of osetting:
Example 1 - The temperature in the cabinet is operating colder than
the actual setpoint.
With a setpoint of +4°C, the actual temperature inside the cabinet is
between +2 and +4°C. The desired temperature range is between +3
and +5°C. This means that “CA”, in this case, should be -1,0K, so that the
refrigeration system stops 1,0K before and starts 1,0K later than the
setpoint normally otherwise would dictate.
Example 2 - The temperature in the cabinet is operating warmer than
the actual setpoint.
With a setpoint of +4°C, the actual temperature inside the cabinet is
between +4 and +6°C. The desired temperature range is between +3
and +5°C. This means that “CA”, in this case, should be 1,0K, so that the
refrigeration system stops 1,0K later and starts 1,0K earlier than the
setpoint normally otherwise would dictate.

Ordinary use
The cabinet is not suited for storing items that emit vapours, as they
might corrode the cabinet and its components.
All the items stored in the cabinet that are not sealed, or wrapped,
should be covered to reduce the risk of corrosion of the cabinet and its
components.
Items placed on the bottom of the cabinet will cause the air circulation
to be impeded, reducing the cabinets performance.
Items should be evenly distributed in the cabinet, with minimum layerthickness / maximum surface. And at the same time, the air should be
able to circulate freely between the items.
Keep the marked areas in the cabinet
(shown on this page) clear of all items,
ensuring adequate air circulation, and
therein cooling.
Do not place items beneath the lowest
shelf bracket.

Regular maintenance
Always disconnect the cabinet before cleaning.
The cabinet should be cleaned internally with a mild soap solution
(Max. 85°C) at suitable intervals and checked thoroughly before it is put
into operation again.
It is recommended that the re-evaporation tray is cleaned at least once
a year. This shall only be done while the cabinet is turned o.
Be careful not to damage the defrost water tube and heating element
(located in the tray) when cleaning.
Cleaning agents containing chlorine or compounds of chlorine as
well as other corrosive agents, may not be used, as they might cause
corrosion to the stainless panels of the cabinet and the evaporator
system.
Cleaning
The compressor compartment and in
particular the condenser must be kept free
from dust and dirt. This is best done with a
vacuum cleaner and a brush. Do not ush
compressor compartment or evaporator
with water as this may cause short-circuits
in the electrical system.
Page 24

Door gaskets
Door gaskets are an important part of a cabinet, door gaskets
with impaired functionality reduces a cabinets seal with the door.
Impaired seals can lead to increased humidity in the storage chamber,
iced evaporator (and thus reduced cooling capacity), and in some
cases, decreased lifetime expectancy of the cabinet. It is therefore
very important to be aware of the door gaskets condition. Regular
inspections are recommended.
The door gasket should be
cleaned regularly with a mild
soap solution.
If a gasket is to be replaced,
please contact your local Gram
BioLine distributor.
