4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.
3.2 Product overview
The 9525sc degas system removes CO2 and measures degassed conductivity from the sample
stream. The 9525sc degas system boils the sample and distills the liquid through the crossover
system to remove CO2 gas from the sample stream. The unit removes CO2 gas through the steam
vent, and distills the flow through the sample cooler. The unit then measures the conductivity of the
sample.
Use the 9523sc cation conductivity panel to measure specific, cation and degassed conductivity. The
combined system is known as the 9525sc degas cation conductivity (DCCP) system. Refer to
English

Figure 1. Refer to the 9523sc user instructions to add the 9523sc cation conductivity panel to the
degas system.

4.2 Electrical installation
D A N GE R
Electrocution hazard. Always remove power to the instrument before making electrical connections.
Supply power to the instrument with conduit or a power cable. Make sure that a circuit breaker with
sufficient current capacity is installed in the power line. The circuit breaker size is based on the wire
gauge used for installation.
For installation with conduit:
• Install a local disconnect for the instrument within 3 m (10 ft) of the instrument. Put a label on the
disconnect that identifies it as the main disconnect device for the instrument.
English
9
• Make sure that the power and safety ground service drops for the instrument are a minimum of
3.31 mm2 (12 AWG) (for 110 V) and a minimum of 2.08 mm2 (14 AWG) (for 220 V) and the wire
insulation is rated for 300 VAC or higher and 60 °C (140 °F) minimum.
• Connect equipment in accordance with local, state or national electrical codes.
• Connect the conduit through a conduit hub that holds the conduit securely and seals the enclosure
when tightened.
• If metal conduit is used, make sure that the conduit hub is tightened so that the conduit hub
connects the metal conduit to safety ground.
For installation with a power cable, make sure that the power cable is:
• Less than 3 m (10 ft) in length
• Rated sufficient for the supply voltage and current
• Rated for a minimum of 60 °C (140 °F) and applicable to the installation environment
• Not less than 3.31 mm2 (12 AWG) with applicable insulation colors for local code requirements
• A power cable with a three-prong plug (with ground connection) that is applicable to the supply
connection
• Connected through a PG11 or 3/4 inch cable gland (strain relief) that holds the power cable
securely and seals the enclosure when tightened
• Does not have a locking type device on the plug
• Near to the instrument with easy access by personnel

Connect the controller to power with conduit or a power cord. Make connections at the same
terminals, regardless of the type of wire used. Refer to Table 1 to connect conduit or a power cord.
Put each wire into the applicable terminal until the insulation is flush against the connector with no
bare wire seen. Pull lightly after insertion to make sure that there is a tight connection. Refer to
Figure 5.
1. Loosen the four captive screws.
2. Carefully open the electrical cover.
3. Use a knockout punch driver to punch a hole in the top of the NEMA electrical enclosure.
4. Attach a power cord strain relief connector to the hole.
5. Attach the power cord to the strain relief connector.
6. Connect the live (L), neutral (N), and ground (G) wires as shown in Figure 5.

4.3 Plumbing
4.3.1 Connect the plumbing
Note: Clean and deburr all of the connecting pipe and tubing before installing.
4.3.2 Connect the cooling water
Note: Adjust the cooling water flow at the cooler outlet.
The cooling water must have the properties that follow:
• An approximate flow rate of 3.78 liters/minute (1 gallon/minute)
English
11
• An approximate temperature of 25 °C (77 °F)
• Clean with no suspended solids and a low hardness
• Low in chlorides because chlorides can cause corrosion in the stainless steel coil and shell
Connect the cooling water as follows:
1. Use a 3/8-inch NPT (national pipe thread) connection to connect the tubing to the cooling water
outlet at the top of the cooler. Refer to Figure 6. Make sure that the outlet drains into a floor drain.
2. Use a 3/8-inch NPT connection to connect tubing to the cooling water inlet at the bottom of the
cooler. As an alternative, connect the tubing to the cooling water inlet at the top of the cooler.

Burn hazard. Obey safe handling protocols during contact with steam.
Make sure that the samples supplied to the instrument are at a temperature of 25 °C ± 1 °C (77 °F ±
2 °F). Make sure the pressure is controlled by a back pressure regulator or a head cup to keep a
constant sample flow rate.
Install the needle valve/rotameter on the sample inlet before the degas unit. If the 9523sc cation
conductivity panel is used, install the needle valve/rotameter on the sample inlet before the cation
conductivity panel.
Install the flow cells in an orientation that keeps the water level near the crossover section of the
degas chamber. The sample outlet from the panel must be level with the crossover section of the
degas chamber.
Incorrect release of steam from the degas chamber or incorrect flow cell locations can have an
unwanted effect on the performance of the system.
12
English
Complete the steps that follow to connect the sample line. Refer to Figure 7.
1. Use a 1/4-inch NPT connection to connect the sample line to the sample inlet.
2. Use a 1/4-inch NPT connection to connect the sample outlet line to the sample outlet. The outlet
must drain into a floor drain.
3. Unroll the condensate drain tube.
4. Push the condensate drain tube through the hole in the rear of the unit. Make sure that the outlet
drains into a floor drain.
5. Remove the red cap from the steam vent.
6. Remove the red cap from the vacuum break.
7. Make sure that the tubing does not touch the hot surfaces.

Notes:
• The power indicator light will start and stop with the heater.
• For units installed in a small shelter or prefabricated structure, it is recommended that the steam
vent is pointed to the outer side of the structure.
The heater temperature is factory-programmed at 108 °C (226 °F) at the factory and the sample flow
rate must be between 100 and 150 ml/minute (6 and 9 L/hr). Decrease the flow rate if there is no
vapor at the steam vent. Droplets of hot boiling water at the steam vent shows that the distilled water
is too hot. If the distilled water becomes too hot, decrease the set temperature or increase the flow
rate within the specified range.
Refer to Figure 9 on page 16.
1. Set the water flow to the cooler to on.
2. Examine cooler for leaks at the two cooler inlets and the outlet.
3. Examine the outlet tube for correct drainage.
4. Set the sample flow to on.
5. Adjust the sample flow to 100 to 150 ml/minute.
6. Look for leaks and for correct drainage.
7. Set the temperature controller power switch to on. Refer to Figure 8. The power light comes on.
8. Make sure that the display on the controller is on.
9. Monitor the temperature controller. The temperature will increase continuously to approximately
106 °C.
Note: The temperature controller may not reach 106 °C, based on local air pressure and
temperature. The heater will heat the sample to the boiling point of water. If there is a constant
column of water vapor from the steam vent, the unit is operating correctly.
