Section 6
Disconnect the power cord prior to performing any maintenance.
Handle the unit with care. Sudden jolts or drops can damage the unit's
components.
After time, the unit's stainless steel surfaces may show spots and become
tarnished. Normal stainless steel cleaners can be used.
Clean the bath vessel and built-in components at least every time the bath
liquid is changed. Use water and a soft cloth.
Do not use scouring powder.
The inside of the bath must be kept clean in order to ensure a long service
life. Substances containing acidic or alkaline substances and metal shavings
should be removed quickly as they could harm the surfaces causing corrosion.
If corrosion (e.g., small rust marks) should occur in spite of this, cleaning
with stainless steel caustic agents has proved to be suitable. These substances
should be applied according to the manufacturer's recommendations.
For cleaning the baths do not use any substances which contain
solvents.
In order to maintain the cooling capacity of the unit, clean the fins two to
four times per year, depending on the operating environment.
Switch off the unit and unplug the power cord.
For ARCTIC A40/A40B:
1 Remove the condenser panel.
2 Clean fins with brush or similar tool.
3 Replace the panel.
For all other refrigerated baths:
Clean the fins with compressed air.
For extreme soiling a qualified technician will need to remove the cooling
compressor casing.
