The durability of the reagents is only ensured at temperatures below
10 °C.
For this reason, the device has a refrigerator. This system is easy to
handle and requires no maintenance. Commissioning takes place by
plugging in the mains connector.
The refrigerator compressor is protected by the AMTAX inter 2 housing
and must not be exposed either to spray water or water jets.
3 Valve for the null solution
4 Valve for the standard solution
Figure 14 Thermostat of the cooling machine
Note: To maintain the required temperature range, the controller on the
thermostat of the cooling machine must be in position 5–6.
Position 6–7, or very cold installation rooms, can cause freezing!
