Page 4 • WatchGas recommends to “bump test” the sensors on a regular basis depending on the usage model to confirm their ability to respond to gas by exposing the detector to a gas concentration that exceeds the alarm setpoints. Manually verify that the audible and visual alarms are activated.
Page 5 Do not attempt to disassemble, adjust, or service the detector unless instructions for that procedure are provided in the technical reference guide, and/or that part is listed as a replacement part. Use only WatchGas replacement parts. Refer to Spare Parts List.
Page 6 SST Mini Very similar to its slightly smaller SST Micro counterpart, the SST Mini offers an optional NDIR or traditional high-powered catalytic bead as the detection method for LEL. This is done through our WatchGas Device Link Application. SST Pump Pumped four gas device with our on in-house designed pump allows a draw of up to 30 meters (100 Feet).
Page 7 Lithium polymer cells exposed to heat at 266°F (130°C) for 10 minutes can cause a fire and/or explosion. NOTE: To replace the battery, contact WatchGas or authorized distributor. The battery can only be replaced by the original manufacturer part, which is SST4-MIC-MIN-BAT for the SST4 Micro and Mini, and SST4- PUMP-BAT for the SST4 Pump.
