Attaching the Accessories

Installing the Pump Module

The JJS motorized pump module is an optional accessory for the detector. The pump module is designed to be used with the sample probe to test for gases in confined spaces.

Figure 4. Installing the Pump Module

Table 12. Installing the Pump Module

Item	Description
1	Motorized pump module
2	Sensor filter
3	Detector
4	Machine screws (2)

1. To install the pump module, deactivate the detector.

2. Remove the two machine screws and the sensor cover. Remove the sensor filter from the sensor cover and insert it into the pump module.

3. Attach the pump module to the detector and replace the two machine screws.

4. Activate the detector. The detector performs the start-up self-tests and the pump test. Refer to Pump Test.

5. If the pump has been purchased separately (not included with the detector), the pump flow rate must be set prior to using the pump. Refer to Pump in the Tech Mode section.

Note

Do not exchange pump modules between detectors.

Attaching the Sample Probe

The sample probe is used to safely test for gas in confined spaces before entering.

Figure 5. Attaching the Sample Probe

Table 13. Attaching the Sample Probe

Item	Description
1	Motorized pump module
2	Connector
3	Sample probe
4	Sample probe 10 in. tubing (custom lengths can be ordered)
5	Flexible connector hose

Warning

The sample probe must be used with the pump module only. Ensure that all connections are secure before sampling.

1. Make all of the required connections as illustrated in Figure 5 Attaching the Sample Probe.

2. Activate the detector.

Warning

If the length of the tubing is 50 ft. or longer, the Fast Pump option must be enabled prior to sampling. Refer to Fast Pump in user options.

3. Insert the sample probe tubing into the confined space.

Depending upon the length of the tubing and the type of gas in the confined space, allow a minimum of 3 seconds per ft. of hose to ensure the readings stabilize before entering the area.

Example: 50 ft. = 2.5 minutes
