NOTICE
The PCS.base is a portable device which must only be oper-
ated inside the original transport bag. The bag must be open
during operation.
Only operate and transport the unit upright. Operating the
device with the cover closed or outside the specifications is
prohibited!
CAUTION
Damage/health hazard due to heater leakage
Check the device for obvious leaks before every use and at
regular intervals. Any leaks must be repaired prior to using
the device. In addition to gas leaks, leaking fluids in particular
can post an electrical and health hazard.
5.1 Switching on the PCS.base
After switching on the supply voltage the cooler starts to cool
the cooling block.
The target temperature is factory preset to 5 °C. The alarm
limit is defined at +5/-2 K.

5.2 Operating the sample gas pump
DANGER
Toxic, corrosive gases
The measuring gas led through the equipment can be hazard-
ous when breathing or touching it.
a) Check tightness of the measuring system before putting
it into operation.
b) Take care that harmful gases are exhausted to a save
place.
c) Before maintenance turn off the gas supply and make
sure that it cannot be turned on unintentionally.
d) Protect yourself during maintenance against toxic / cor-
rosive gases. Use suitable protective equipment.
The pump will only run after reaching the block temperature.
It is only intended to convey gaseous mediums. It is not suit-
able for liquids.
Operation under primary pressure is prohibited. The flow in-
side the device (operational regulation via flow meter with
built-in needle valve) should always be at least 50 L/h. Throt-
tling greatly will shorten the life of the sample gas pump.
CAUTION
Hot surface
Risk of burns
Housing temperatures may be high during operation.
Allow the unit to cool down before performing maintenance
or repairs.
