Attaching Individual Accessories

So far, we have looked at the mechanical and diagnostic procedures for testing and calibrating the device. However, many of these tests will require you to attach certain hoses and intake valves. So, it is just as important to understand the processes of how to attach these accessories. This section will begin on page 59 of your owner's manual. You will encounter a great many detailed diagrams and it is highly recommended that you become familiar with each one before attempting any of the tests that we have previously described. So, let us take a look at how to attach various pieces of equipment to your detector.

Installing the Pump Module

This is a device that can actually be used completely separately to detect gases while it can also be used with a probe (GA-PROB1-1). This is advantageous if you are attempting to detect a gas in a relatively confined space. You will need to refer to the section in the owner's manual entitled Attaching the Sample Probe to learn how to measure gases with the pump module.

Refer to figure 6 when performing this option. First, deactivate your detector. Remove the two back machine screws; thus freeing the sensor cover. Take out the filter and place it into the pump module (M5-PUMP). Attach the module directly to the detector (via the filter) and reattach the two screws that you have just removed. Attach the sample probe (if necessary). If you wish to use an auxiliary filter (M5-AF-K3), you will need to refer to this section in the manual. Finally, reactivate the unit. Note that a pump test will be performed when it starts up.

Replacing a Pump Filter.

Refer to figure 7 when performing this step. Recall that if you are using either an auxiliary filter or an older module, you should instead refer to the section entitled Attaching the Auxiliary Filter in the owner's manual.

First, deactivate the detector. Remove the filter window screw and then the filter window itself. Take out the old filter and make certain that there is no dirt or debris. Replace the filter with the new one. Place the filter window back on (again ensuring that no debris is present) and then, insert the filter window screw. Reactivate the unit. As previously, the detector will perform a pump test during this process. This is necessary to verify that the detector is functioning correctly. If the pump test fails, you may have to refer to the troubleshooting section of the manual. Additionally, check for any particulate material in the pump to make certain that there is no blockage present.

You should note that in areas where there are known to be high particulates, you can use the auxiliary filter in tandem with the normal filter; this will provide an extra level of protection. If you need to order an additional filter, you can order the correct make and model number by referring to the replacement parts and accessories section of the manual. We will next examine how to replace the pump nozzle of the device.
