pump unit and the rubber sample nipple. Pump Unit The pump unit is housed in a red plastic case. The silver inlet fitting on the right side of the pump unit allows for connection of a rubber sample nipple or a hose and probe. The inlet fitting’s clear holder retains 2 hydrophobic membranes and a mesh disk. The black cap at the bottom right of the pump unit allows for battery compartment access. The pump unit needs one AA alkaline battery. The exhaust fitting is located on the bottom left of the pump unit, next to the battery compartment. A POWER button, a buzzer opening, a POWER LED, and a FLOW LED are located along the middle front of the pump unit. The sensor adapter at the top of the pump unit mates to the GX-3R or GX-3R Pro. There are different sensor adapters for each instrument type. When installed, the text on the front of the GX-3R/GX-3R Pro and RP-3R should be facing the same way.

GX-3R Pro easier. Rubber Sample Nipple A cone-shaped 4-inch long rubber sample nipple is included with the RP-3R. It can be installed by pushing the larger end over the inlet fitting. The smaller end can be inserted in a hole or some other access point to sample the environment. Optional Hose & Probe A sample hose and probe (optional accessories) may be connected to the inlet fitting. Sample hose lengths are available from 10 feet to 100 feet (see Parts List at the end of the manual). CAUTION: Sample hose lengths of more than 100 feet are not recommended for the RP-3R because of flow rate reduction. Normal Operation 1. Start up the GX-3R or GX-3R Pro and enter normal operation as described in the appropriate Operator’s Manual. 2. Press the black retaining tab lever on the left side of the RP-3R. WARNING: Installing the GX-3R or GX-3R Pro onto the RP-3R without pressing the black retaining tab lever may result in damage to the RP-3R. 3. Be sure the front labels on the GX-3R or GX-3R Pro are facing the same way as the front labels on the RP-3R. 4. When viewing the GX-3R or GX-3R Pro and RP-3R from the front, engage the RP-3R’s right- hand retaining clip with the GX-3R or GX-3R Pro. 5. Push the left side of the GX-3R or GX-3R Pro down until the instrument is seated in the RP-3R. Release the black retaining tab lever and ensure that both retaining clips are fully engaged. When fully engaged, the GX-3R or GX-3R Pro should not move around at all. CAUTION: If the RP-3R is not fully engaged, the unit will not respond to the target gases properly. www.GlobalTestSupply.com Find Quality Products Online at: [email protected]

7. Turn on the RP-3R by pressing and holding the POWER button until the RP-3R beeps and the POWER LED turns green. WARNING: While the GX-3R or GX-3R Pro is installed in the RP-3R, the pump must be on for the GX-3R or GX-3R Pro to function as a gas detection monitor. 8. Go to the area to be sampled. Rubber sample nipple: Insert the rubber sample nipple into the vessel or enclosed area. Allow the RP-3R to sample for 90 seconds before observing the reading on the GX-3R or GX-3R Pro. Hose and probe: Hold the probe in the area to be sampled. If necessary, the hose and probe may be lowered into the sample area. Allow the pump unit to sample for 90 seconds before observing the reading on the GX-3R or GX-3R Pro. NOTE: The hose and probe do not have their own hydrophobic filters. Take care to not draw liquid through the hose and probe. 9. Monitor the GX-3R or GX-3R Pro’s gas readings and take appropriate action if gas alarms occur. 10. When sampling is complete, turn off the RP-3R by pressing and holding the POWER button until the RP-3R sounds a long beep and the POWER LED turns off. 11. Turn off the GX-3R or GX-3R Pro. 12. Press the black retaining tab lever on the left side of the RP-3R.

The RP-3R can operate in a higher-flow mode (standard) or a lower-flow mode. 1. With the RP-3R turned on, press and hold the POWER button for 1 second. 2. The FLOW LED will change state (ie. from flashing to steady or vice versa). NOTE: At temperatures below -10°C, the RP-3R must operate in higher-flow mode. If operating in lower-flow mode, the RP-3R will automatically switch to higher-flow mode at -10°C. Any attempt to switch to lower-flow mode will be blocked. Alarms The table below outlines the alarms that may occur on the RP-3R. Flow Mode LED Indication Higher-flow mode FLOW LED steadily yellow Lower-flow mode FLOW LED flashes yellow Alarm Type Visual Indications Audible Indications Other Indications Recommended Action Low Battery POWER LED flashing none none Replace the battery. Dead Battery POWER LED flashing constant buzzer none Replace the battery. Low Flow NOTE: A low flow alarm may get combined with a low or dead battery alarm since a low battery voltage may cause the pump to stop working. FLOW LED quickly flashing intermittent buzzer pump stops • Check the rubber sample nipple and filters to make sure they are clear. • If a hose and probe are used, check them for kinks or obstructions. • Press and release the POWER button to reset the alarm. • If the low flow condition persists, the pump may need servicing. www.GlobalTestSupply.com Find Quality Products Online at: [email protected]

1. Push down and rotate the black battery cap counterclockwise until it stops. 2. Pull the battery cap away from the pump unit. 3. Remove the old battery. 4. Insert the new AA alkaline battery + end first into the pump unit. The battery orientation is shown on the back of the pump unit. 5. Reinstall the black battery cap by pushing it down and turning it clockwise until it stops. Replacing the Hydrophobic Disk Filter and Wire Mesh Disk 1. Grasp the clear filter holder (under the inlet fitting) and turn it 1/4 of a turn counterclockwise. 2. Pull the filter holder away from the pump unit. 3. The hydrophobic disk filters and wire mesh disk are located in the pump unit and are retained by a rubber gasket. Gently pull out the rubber gasket with needle nose pliers taking care not to damage the gasket. The GX-3R version of the RP-3R has a clear spacer below the gasket that may come out. The GX-3R Pro version of the RP-3R does not have this spacer. 4. Remove the old hydrophobic filters and/or wire mesh disk from the gasket. A hydrophobic filter is located on either side of the wire mesh disk. 5. Install the new hydrophobic filters and/or wire mesh disk making sure a hydrophobic filter is located on each side of the wire mesh disk.

the gasket, reinstall the spacer. Be sure the hole in the spacer lines up with the hole in the housing. 7. Reinstall the gasket/filters/mesh into the pump unit. 8. Align the two tabs on the bottom of the filter holder with the two slots in the pump unit. Push the filter holder into the pump unit and turn it 1/4 turn clockwise until it snaps into place.
