1.0 INTRODUCTION 1.1 Purpose The purpose of this manual is to describe the Pylon model 6800 AB6A optional internal

pump and its use. 1.2 Scope This manual covers the description, use, and installation of the Pylon model 6800

optional internal pump (hereinafter just referred to as the 6800) which is installed in the Pylon model AB6A monitor (hereinafter just referred to as the AB6A). A detailed description of the AB6A and its operation is beyond the scope of this manual. Please refer to Pylon manual number 7940010 for more information on the AB6A.

1.3 General Description The 6800 consists of the following parts: PPN 1 DESCRIPTION QTY 2020011 Fitting, male 2 Each 2020003 6.4 mm (1/4") I.D. PVC Tubing 2 8 Feet 7101210 Assembly, pump module, AB6A 1 Each 7100340 Flowmeter, 0.15 to 1 l/min, c/w barbed tubing fittings 1 Each 1 Pylon Part Number 2 Tubing should be replaced regularly to prevent possible contamination. Inexpensive clear PVC plastic

tubing may be used with the 600A/610A cells. The pump is User installable. The pump allows the User to use active cells such as the Pylon model 600A or 610A for

the AB6A Standard Continuous, Standard Grab, and Quasi method measurements without the requirement for a separate external pump. The 6800 is required should the AB6A Quasi method be used for measurements.

of 26


NOTE The included flowmeter is used to control and limit the flow

rate to less than 1 l/min because the recommended flow rate for the Standard Continuous method is 0.5 l/min. For the Standard Grab and Quasi methods, a higher flow rate up to the maximum pump flow rate of 2.5 l/min may be used by replacing the provided flowmeter with a 0.2 - 4 l/min flowmeter such as the Dwyer VFB-65-BV flowmeter.

Pylon offers this flowmeter in the model 6710 Flowmeter Kit

which may be ordered under Pylon part number 7101010. In addition, the 6800 can also be used to flush active cells after samples have been

measured when the flushing process described in the 600A/610A manual (Pylon manual number 7940002) cannot be performed immediately.

Figure 1 - Model 6800 AB6A Pump Kit 1.4 Theory of Operation The pump module assembly is installed in the AB6A monitor. The User may then turn

the pump on and off via the AB6A Graphical User Interface (GUI) or, depending on the selected method and programmed parameters, the AB6A may automatically turn the pump on and off.

of 26


The flowmeter is used to control the flow rate of the gas sample through the cell. The remaining components are used for setting up the flow system. 1.5 Specifications Table 1 - 6800 Specifications below provides the nominal specifications for the 6800. Flow rate Range 1 : 0 - 2.5 l/min Operating Temperature Range: 0 to +40 C (+32 to +104 F) Storage Temperature Range: -20 to +75 C (-4 to +167 F) Relative Humidity Range 2 : 0 to 90 % Length (Pump Module Only): 9.4 cm (3.7 in) Width (Pump Module Only): 6.9 cm (2.7 in) Height (Pump Module Only): 8.5 cm (3.4 in) Weight (Pump Module Only): 182 g (0.4 lb) 1 The pump flow rate is controlled and limited by the flowmeter. 2 Non-Condensing.

Table 1 - 6800 Specifications 2.0 OPERATING PROCEDURES 2.1 Measurement Pumping 2.1.1 Equipment Requirements The following lists the necessary equipment 1 required to use the 6800: Item Mfr Model Description Qty 1 Pylon AB6A Portable Radiation Monitor 1 2 Pylon 600A /

610A Active Cell A/R

3 - - 6.4 mm (1/4 inch) barbed tubing mating connectors to connect the 6800 system to the sampling chamber, source, etc.

A/R

1 Equivalent equipment is permitted.

The following lists the optional equipment 1 that would assist in the use of the 6800: Item Mfr Model Description Qty 1 - - Drierite Tube c/w Drierite 1 2 Gelman 1109 Filter Holder, In-Line 1 3 Pall 1107 Filter Holder, Open Face 1 4 - - 25 mm Glass Fiber Filters, 0.8 um A/R


NOTE The User must be familiar with the operation of the AB6A

monitor before the 6800 can be used. Please refer to the AB6A Instruction Manual (Manual Number 7940010) for information on the use and operation of the AB6A.

2.1.2 Constraints The following items are constraints for the use of the pump. Tubing Length The pump is a 12VDC miniature diaphragm pump that can provide a flow rate of 2.5

l/min under no load. The tubing that is used to connect the various components introduces a load on the pump that increases with the length of tubing that is used.

The total length of tubing that is used for connect the various components should not

exceed 3 meters (10 feet). Radon Daughters Radon daughters in the gas sample can affect the radon measurement. As these radon

daughters are solids, they attach themselves to dust particles in the gas sample. It is recommended that a filter be installed in line with the pumping system before the

flowmeter to filter out the particulates and therefore the radon daughters. A Gelman part number 1109 in-line filter holder or Pall Life Sciences part number 1107

of 26


open face filter holder and a 25 mm diameter, 0.8 um filter or equivalent are recommended.

Pylon offers in-line filter kits for this purpose. The model 6600 In-Line Filter Kit may be

ordered under Pylon part number 7100900 and the model 6610 Open Face Filter Kit may be ordered under Pylon part number 7100910.

Humidity High levels of humidity can damage the interior of the cell if it condenses inside the cell. It is recommended that, in cases of high levels of humidity, a drying mechanism be

installed in line with the pumping system before the flowmeter to remove excess moisture from the incoming gas sample.

A drierite tube with drierite or equivalent is recommended. The drierite must be replaced

or re-activated when required. Pylon offers 2 versions of drying kits that may be used; a small and a large. The model

6620 is the small drying column kit and may be ordered under Pylon part number 7100920. The model 6630 is the large drying column kit and may be ordered under Pylon part number 7100930.

2.1.3 Setup The User should be familiar with the operation and use of the AB6A before setting up or

using the equipment. The simplest general connection setup is shown in Figure 2 - Minimum Pump System

Setup. However, as indicated in the active cell manual (Pylon Part Number 7940002), it is recommended that filters and, if necessary, a drying column be used in the setup. Figure 3 - Closed System Sample Acquisition Setup and Figure 4 - Open System Sampling Acquisition Setup shows typical setups for using the internal pump to flow samples into an active cell.

Both grab sampling and continuous sampling can be performed with these setups. Please

refer to manual number 7940002 - 600A and 610A Operator's Manual for more information.

of 26


NOTE

The internal pump module must be installed in order to be

able to select the Internal Pump in this menu as well as run it to set the flow rate.

4) Turn on the pump by pressing Start. 5) Using the flowmeter, adjust the pump flow rate to the desired setting.

NOTE Although the maximum flow rate for the active cells is

specified to be 10 l/min, the flowmeter should be adjusted to 0.5 l/min for the Standard Continuous method. The Sensitivity of the active cells that is used in the calculations for the Standard Continuous method is dependent on the flow rate and will change with different flow rates. The Sensitivity of cells that are calibrated by Pylon are based on a low flow rate.

NOTE

The User may use higher flow rates, if desired, as long as the

active cells have been calibrated at the higher flow rate. 6) Turn off the pump by pressing Stop. 7) Enter the pump flow setting in the flow rate field in this menu.

NOTE The entered flow rate will be displayed in the Setup tab display

of the method. When appropriate, this value will be used in the automated calculations. This value will also be specified in the reports for manual calculations performed by the User.

8) Press the Save button to save the settings. 9) Exit the Flow Setup menu by pressing Done or the red "x" box in the upper right

of 26


corner of the display. The internal pump system is now ready for measurements. 2.2 Cell Flushing As indicated in the cell manuals, cells should be flushed immediately after the sample has

been measured to remove the sample from the cell. If the sample is not removed, the background of the cell will increase at a faster rate which may render it useless for the desired measurements in the future.

This section describes how to use the AB6A internal pump to flush the 600A / 610A active

cells when the method described in the active cell manual (Pylon manual number 7940002) cannot be performed in a timely fashion.

CAUTION THIS METHOD JUST USES NORMAL OUTSIDE AIR TO

FLUSH THE CELLS. AS THE RADON LEVELS OF THIS NORMAL OUTSIDE AIR ARE NOT NECESSARILY KNOWN, THE CELL MAY REMAIN PARTIALLY CONTAMINATED. IT IS RECOMMENDED THAT THE CELL FLUSHING PROCEDURE DESCRIBED IN THE ACTIVE CELL MANUAL BE FOLLOWED AS SOON AS PRACTICABLE AFTER THIS PROCEDURE IS PERFORMED.

2.2.1 Equipment Requirements The following lists the necessary equipment 1 required to use the 6800 to flush active

cells: Item Mfr Model Description Qty 1 Pylon AB6A Portable Radiation Monitor 1 2 Pylon 6800 Optional AB6A Internal Pump c/w Tubing and

Connectors 1
