<strong>6100CR</strong> <strong>Refrigerated</strong> <strong>Sampler</strong><br />
Section 1 Introduction<br />
1.1.1 Connection to<br />
Pressurized Line<br />
The <strong>Refrigerated</strong> <strong>Sampler</strong> is permanently connected to a pressurized<br />
discharge line from which the sample liquid is periodically<br />
drawn. A filter on this line prevents any solids present in<br />
the effluent from entering the sampler. A valve allows sample to<br />
flow only when the <strong>6100CR</strong> needs to take a sample. A pressure<br />
regulator reduces the line pressure to a safe fill value. Once<br />
inside the refrigerated sampler, the sample flows through a serpentine<br />
coil inside an aluminum container (the ballast) at the<br />
bottom of the refrigerator for cooling before injection into the<br />
sample vials. Waste sample is discharged from the drain line.<br />
1.1.2 Controller Operation The microprocessor in the controller governs the operation of the<br />
mechanism that selects, opens, fills, and closes the sample<br />
bottles. A motor rotates the bottle rack placing each bottle<br />
directly under the fill mechanism. The bottle rack is kept chilled<br />
by its location inside the refrigerator. When the filled rack is sent<br />
to a lab for analysis, it may be kept cold by filling the inside of<br />
the rack with ice and placing in the styrofoam mailer to keep<br />
samples cool during the transport to the lab for analysis.<br />
The fill operation consists of:<br />
• Purging the sample line<br />
• Rotating the bottle rack to place the bottle in position for<br />
filling<br />
• Opening the valve on the sample bottle cap<br />
• Lowering the fill needle into the sample bottle<br />
• Filling the sample bottle with the liquid sample<br />
• Withdrawing the fill needle from the sample bottle<br />
• Closing the valve on the sample bottle<br />
When filling the sample bottle, the <strong>6100CR</strong> actually overflows<br />
the bottle to comply with EPA protocol to fill and dump the<br />
sample bottle. This overfilling keeps residual air pockets from<br />
remaining between the bottle and the lid, thus providing a representative<br />
sample. The excess water drains out of the sampler<br />
through an overflow tube attached to a fitting on the back of the<br />
controller. The controller also determines, through programming,<br />
when and how the <strong>6100CR</strong> takes its samples.<br />
1.2 Quick-Start Operating<br />
Procedure<br />
Note that the quick-start procedure assumes you have some<br />
familiarity with the unit. If you do not, please do not try to<br />
operate the unit without first reading this entire document.<br />
1. Put a new bottle rack in the unit. Make sure the handles<br />
on the bottles are all closed (turned sideways 90° to the<br />
bottles). See Figure 1-2. Improperly oriented handles will<br />
jam the unit.<br />
2. Turn the unit on by pressing the On/Off key on the keypad.<br />
When the unit is off, the display will be blank. When<br />
the unit is on, there will always be something on the display.<br />
