3GENERAL DESCRIPTION
The objective of the degassing system is to raise the tem erature of the sam le to its boiling oint,
in order to remove the greatest amount of CO₂ from it. To maximize the extraction efficiency of
CO₂ and minimize the roduction of water va or, recise tem erature control has been designed
by means of a control loo formed by a tem erature controller, an RTD and a heating cartridge
that rovides the necessary heat, to raise and maintain the tem erature at the required set oint.
The CO₂ extracted from the sam le leaves the atmos here through a tube, which travels through
the interior of a cooler, which guarantees that, in case of va or occur at any time, it will condense
and will be removed by means of the general drainage of the system.
Drainage funnel
After the elimination of CO₂, the sam le requires cooling to erform a measurement of degassed
conductivity under o timal conditions. That is why the sam le is directed to a cooler, for the
o eration of which, there are two o tions: Sam le is cooled with cooling water from an external
source or it exchanges heat with itself, by assing the sam le through the cooler rior to assing
through the heater.

Heat exchanger Heating cartridge
The o tion of self-cooling, guarantees great stability to the system in the event of disturbances in
the flow or tem erature of the sam le, as well as, not requiring a consum tion of cooling water
and the installation required for cooling water su ly.

CAUTION: THE NECESSARY PROTECTIVE EQUIPMENT MUST BE USED IN ORDER TO AVOID
KNOCKS, CUTS AND ENTRAPMENTS DURING INSTALLATION. FOLLOW THIS PROCEDURE FOR
CORRECT INSTALLATION.
4.1 Mechanical
This device must be located avoiding vibrations and direct ex osition to sunlight. The system incor orates
four holes in the four corners of degassing system anel, in order to fix it to a vertical wall. The degassing
system must be mounted in vertical osition, using four M-10 bolts in order to fix it to a smooth and bare
wall. It is im ortant that in normal o eration, the rear art of the mounting late doesn’t be accessible in
order to avoid burns to o erators.

Cooling water connections
Cooling water connections are not required when self-cooling o tion is installed. In case of external cooling
water o tion, follow next ste s:
•Kee the length of all tubing to a minimum. Only 80 mm of straight tube, must be res ected
from connection fitting (¼” NPTF) to the revious curve u stream.
•Connect the cooling water IN. Should be i ed to the left lower side of the mounting late, in
¼” nominal bore tube and connected by means of ¼” NPTM fitting to ¼ NPTF connector.
Connection is labelled with the indication “COOLING W. IN”.
•Pi e the cooling water OUT. Should be i ed to the left lower side of the mounting late, in ¼”
nominal bore tube and connected by means of ¼” NPTM fitting to ¼ NPTF connector.
Connection is labelled with the indication “COOLING W. OUT”.

Sample inlet and outlet connections
•It is advisable, the use of corrosion resistant i ework, suitable for the fluid being sam led, in
order to connect degasser system, to sam ling stream.
•Kee the length of tubing to a minimum. Only 80 mm of straight tube, must be res ected from
connection fitting (¼” NPTF), to the revious curve u stream.
•Connect sam le IN, in the left u er side connections of the degasser system by using ¼” NPTM
fitting to ¼ NPTF connector. Connection is labelled with the indication “SAMPLE IN”.
•Connect sam le OUT, in the left u er side connections of the degasser system by using ¼”
NPTM fitting to ¼ NPTF connector. Connection is labelled with the indication “SAMPLE OUT”.
Sample inlet and outlet connections
Drain connections
All ossible effluents roduced by the degassing system, are directed to a funnel in the lower art of the
anel. Therefore, there is an only drain connection in the system. The drain i e, must be connected to the
½” NPTM threaded connection, in the lower art of the funnel.
Drain i e length must be as short as ossible, and minimum size ½” in order to avoid back ressure.
Furthermore, funnel must be higher than any other oint in drain i e ath and drain oint, must be at
atmos heric ressure.

4.3 Electrical connections
CAUTION: IT WILL BE NECESSARY TO VERIFY THAT THERE IS NO VOLTAGE IN POWER SUPPLY CABLE
BEFORE TO START ELECTRIC WIRING. FOLLOW THIS PROCEDURE FOR CORRECT INSTALLATION:
Power supply connection
Degassing system, must be electrically su lied by connecting ower su ly cable to terminals X0. Required
cable has to be three wires and size of wires must be 4 mm² (L+N+PE). Before connect cable, voltage su ly
must be checked and must be between 100-240 VAC 50/60 Hz.
Power supply terminals block
Follow next ste s:
•O en the steel electrical box, located in the u er art of the anel.
•Verify that the automatic switch (Q1) is switched off. If not, switch them off.
•Introduce three wire ower su ly cable by using M-20 gland in left lower side of electrical box
•Connect the main cables in terminals 1, 2, and ground cable in green/yellow terminal, in X0
terminals block, in the lower side of terminals.
•Finally, adjust gland to the cable and ensure that is correctly clam ed.

5START UP
DANGER: TO AVOID THE RISK OF BURNS, IT IS ESSENTIAL BEFORE START-UP, VERIFY THAT IS
NOT POSSIBLE TO ACCESS THE REAR PART OF THE MOUNTING PLATE. IF INSTALLED AS SPECIFIED
IN THIS MANUAL, THERE IS NO RISK FOR ACCIDENTAL CONTACT WITH HOT PARTS. FOLLOW THIS
PROCEDURE FOR SAFE OPERATION:
•O en the cooling water inlet and outlet valves (if installed), for non self-cooling systems and
ensure that a full flow can be seen at the cooling water outlet.
•Gradually o en the sam le inlet valve (not included in the system) and regulate the flow to
achieve a value between 100 to 250 cm³/min. Then is necessary to wait the time required for
the sam le to go out from sam le outlet.

CAUTION: BEFORE TO START-UP THE SYSTEM, IT MUST BE VERIFIED THAT THERE IS SAMPLE
FLOW, FLOWING AT THE SAMPLE OUTLET. IF NOT, HEATER MAY BE DAMAGED BY INTERNAL
OVERHEATING.
•Switch on the circuit breaker (Q1) inside the electrical box to start u the equi ment and close
the electrical box.
•Then, in order to energize heater and tem erature controller, interru ter in electric box cover
must be switched on.
•In normal conditions, after circuit breaker is activated, and interru ter in electric box cover is
switched on, heater and tem erature controller, both will be energized.

•In case of cold starting wait at least half an hour until tem erature gets stabilized for getting
accurate measurements.
Tem erature controller arameters (with exce tion of tem erature set oint) are worksho adjusted and
usually, it won´t be necessary to modify it, but if required, this o eration is described in cha ter 7
(Programming).

Main o eration dis lay is shown when controller is energized and looks like a ears bellow:
The arameters shown in figure above are:
1. These digits, indicate tem erature measured inside boiler in the selected tem erature units, if
system is stabilized, that will be the boiling oint of water in this moment.
2. These digits, indicate the adjusted tem erature set oint in the selected tem erature units. This
arameter must be adjusted according to installation site altitude.
3. If working ro erly, out ut 1 should control heater, then OUT1 light must be green. AT, OUT2 or
