14 START-UP
The thermo-hydraulic controlled cooling system of the EC-L permit automatic start-up of the cooler.
The following description is valid for start-up of the gas cooler for an ambient temperature > 8°C.
N O T E !
Before starting up the gas cooler, it must be placed in its operating
position for at least two hours. The liquid inside the system may have
been redistributed, and this could cause problems in operation.
The following steps should be carried out before initial start-up:

Connect the cooler unit to the mains power supply; Check that the equipment is connected to
the correct mains voltage, 115V or 230V, as shown on the type plate.

Lead the status contact for status alarm to the measuring station;
N O T E !
The status contacts must be connected to the external sample gas pump
or to a valve in the sample gas line to protect the entire analysis system
by immediately cutting off the gas supply in the event of error messages
from the cooler!
15 CLOSING DOWN
N O T E !
The location for the cooler must remain frost-free, even when the unit has
been switched off!
If the cooler unit is put out of action for a short time no particular
measures need to be taken.
We recommend sweeping the cooler with inert gas or ambient air while
the unit is put out of action for a longer time.
C A R E !
Aggressive condensate is possible.
Wear protective glasses and proper protective clothing!
