OVERVIEW

This Leak-Seeker brand Combustible Gas Leak Detector (Model LSCG) is designed for use by HVAC/R, Plumbing, Mechanical Contractors, Facility

Maintenance, Factory Technicians, and other Professional Trades that require ease-of-use features such as a large lighted display with digital information to more quickly pinpoint combustible gas leaks, and at lower concentrations vs. conventional analog (“Lighted LED”) leak detectors.
The LSCG is for use in residential, commercial, and light industrial environments to quickly identify the presence of and isolate the location of at least 30 different combustible gases (see list on page 8-9) that have methane as a component.
The LSCG features 2 Sensory Alarms (Audible & Vibration), plus 3 Gas Concentration Alarms (a “Speedometer Type” PPM scale, a Digital PPM and a Digital LEL% value) to alert and guide operators in virtually any environ- ment. It also features the largest backlit LCD display in its class, and a 20” (51cm) flexible probe for hard-to-reach areas. It has a High/Low Concentration key for locating leaks down to 10 PPM. It also features Auto Calibration, Auto Zero, Auto Off and a rechargeable lithium-ion battery.

COMBUSTIBLE GASES
Methane typically makes up 80 ~ 90% of Natural Gas, and usually also contains smaller amounts of Propane (C3H8), Butane (C4H10) and Etha-ne (C2H6). All four are colourless, odorless, and highly combustible.

SENSOR FUNCTION
To detect combustible gases, the LSCG heats a sensor at the end of the flexible probe. Internal electronics interpret sensor data and communicate results to the large LCD display (The sensor is field replacable. Order CPS part #LSXSCG).

HIGH/LOW CONCENTRATION SETTING
By pressing the “H/L” Key at any time, technicians can easily toggle between viewing PPM concentrations within either a LOW Range (10 to 1,000 PPM) or a HIGH Range (100 to 10,000 PPM).

FIVE TYPES OF ALARMS FOR PINPOINTING LEAKS

1. AUDIBLE ALARM
   The LSCG keypad has a dedicated key for turning the Audible (beep) On or OFF. The audible alarm beeps faster as a technician encounters higher gas concentrations.

2. VIBRATION ALARM
   The LSCG keypad has a dedicated key for turning the Vibration alarm On or OFF. This alarm is particularly useful in noisy surroundings where the audible alarm might be difficult to hear. Vibration frequency increases as gas concentrations increase.

3. “PPM SPEEDOMETER” (ON THE DISPLAY)
   At the top of the LCD, there is an innovative analog “speedometer type” display. If no gas is detected, only a “0” will appear at the top LEFT of the speedometer. But, if gas is detected, the speedometer will “sweep” to the right to reflect the PPM level being detected. This speedometer scale helps technicians (in their peripheral vision) to monitor the “rate of gas concentration change” as they move closer to, or further away from the source of a leak.

4. “PPM” NUMERICAL DATA ON THE DISPLAY
   When the LSCG detects a combustible gas (having a Methane component), it generates numerical “PPM” (“Parts Per Million”) values of Methane on the LCD. A key benefit of this innovative digital display is that it gives HVAC/R technicians specific, real-time, combustible gas concentration values. Therefore, technicians don’t need to remember what multiple LEDS represent as is commonly required on competitive analog leak detectors.

5. “LEL %” NUMERICAL DATA ON THE DISPLAY
   For any gas (with a Methane component) detected, the LSCG will also show an “LEL” or “Lower Explosion Limit” value as a per cent volume. This reading lets technicians know if the gas being detected is close to, or well away from the point at which it might combust. More detailed information on LEL can be found on pages 13-14.

CHARGING THE LITHIUM-ION BATTERY

WARNING

DO NOT CHARGE THE ENCLOSED LITHIUM BATTERY IN THE PRESENCE OF COMBUSTIBLE GAS. Set up and operate the gas detector according to these procedures to reduce the risk of fire, explosions and serious injury and incorrect measurements.

1. IF BATTERY IS LOW, CHARGE IT IN AN AREA KNOW TO BE FREE OF COMBUSTIBLE GAS) by using the original 5V/1A plug and cord supplied.

INITIAL PREPARATION

WARNING

1. Before each use, inspect the LSCG and correct any problems to reduce the risk of injury or incorrect measurements.

2. Ensure that all equipment has been properly inspected.

3. High concentrations of combustible gas(es) can cause explosions, fires and other hazards that could cause serious personal injury or death.

4. Before entering a jobsite, identify/confirm, what gases are known or likely to be present on or around the jobsite.

5. Advance information allows technicians to obtain and use any/all required safety equipment and better prepare to inspect for gas leaks. Know the characteristics of the gas(es) you will be working with and use proper precautions to avoid hazardous conditions.

6. Due to the nature of confined spaces, it’s imperative that technicians entering confined spaces exercise a high degree of caution and take extra steps to ensure their safety while working with or in the vicinity of combustible gases or combustible substances. Working safely in a confined space requires technicians to implement careful preparation, as well as an understanding of the potential hazards within the space being inspected.
   Confined spaces present unique dangers when explosive or flammable gases may be present. Generally, the oxygen content in these rooms varies only slightly, whereas a confined space traps combustible gases and vapors. Therefore, a slow leak can quickly reach an LEL required for combustion or to start a fire.
   Gas detection should begin BEFORE a technician enters a confined space where explosive or flammable gases may be present.
   It’s important to understand that jobsite conditions can change suddenly. The LSCG sensor isn’t able to discern what specific gas (or combination of gases) is being measured. Instead, the LSCG sensor is designed to detect a range of gases (see pages 8-9) that have “methane as a component”.

7. Operate this device according to these procedures to reduce the risk of fire, explosions serious injury and incorrect measurements

CAUTION

1. Ensure there is no dirt, oil, grease, or other petroleum products on the LSCG housing or covering the sensor area. Such materials could cause false or distorted readings. Use only a soft, damp cloth to clean. Do not use any detergents.
2. Check the LSCG for any damage, worn parts, loose connections or any other problems that might affect safety and normal operation.
3. If replacing the sensor, ensure the LSCG is turned OFF. This preventive safety measure can reduce personal injury and instrument damage problems.
4. Use only accessories recommended or supplied by CPS Products, Inc. for this device. Accessories suitable for one brand of equipment may become hazardous when used with other equipment.
5. Do not use any powered equipment if the power switch does not turn it ON and OFF. Any powered tool or device that cannot be controlled with an On/Off switch is dangerous and must be repaired or replaced.
6. After inspecting this device, and reviewing the Troubleshooting Guide, if any doubts, set this device aside and don’t use it for the time being.

QUICK START GUIDE

WARNING: BEFORE WORKING ON A JOBSITE, CONFIRM WHAT COMBUSTIBLE GAS(ES) MIGHT BE (OR EXIST) ON OR NEAR THE JOBSITE WHERE THE TECHNICIAN WILL BE USING THE “LSCG”.

1. IF STORED IN TEMPERATURE EXTREMES, ALLOW THE LSCG TO ACCLIMATE BEFORE FIRST USE.

2. IN AN AREA FREE OF COMBUSTIBLE GAS- Press the ON/OFF key to turn the LSCG ON.

   • a. The LSCG will beep and vibrate once.

3. 3. LSCG WILL AUTOMATICALLY CALIBRATE & START UP
   a. Display will Count Backwards From 40 Seconds- During this time, the gas sensor will heat up and the device will automatically calibrate.
   b. After 40 Seconds- LSCG will beep and vibrate once. The display should show:

   • PPM Speedometer Scale (At Top Of Display): 0 PPM
   • PPM Readout: 0 PPM
   • LEL Readout: 0% (Lower Explosion Limit value)
   • Max Readout: 0 (Lower Right Corner Of Display)

4. c. To Clear Any PPM & LEL Display Values On The Display During Each Warm Up.

5. i. Press AUTOZERO Key- This will return PPM, and LEL readings to “0”.

6. d. Battery Icon (Top Right Portion of Display)- Four “segments” within the icon outline mean the battery is 100% charged. Three segments mean the battery is 75% charged, etc.

7. e. If Entire LCD Flashes & Beeps- Sensor has failed and should be replaced.

AFTER INITIAL START-UP

1. a. Speaker & Vibration Alarm Icons Visible On the Display will be ON (visible in the upper LEFT) by default. These indicate that the Audible and Vibration alarms will operate if the LSCG detects a combustible gas. To turn either alarm OFF, press one or both keys on the keypad.
2. a. APO (Auto Power OFF) Visible At Top Of Display -APO is the default setting.
   If “APO” is Visible -The LSCG will turn OFF (to conserve the battery) if the device has NOT been used for 10 minutes. To enable the LSCG to remain ON constantly, press the APO key so that “APO” is not visible.

SET GAS CONCENTRATION (High/Low Key)
a. Use the Concentration Setting High/Low Key (H/L)

1. X10” (Low Concentration Scale: 10 To 1,000 PPM)- LOW is the default sensitivity- “X10” will be visible on the RIGHT SIDE of the display. “X10” means that any PPM value visible (to its left) is to be multiplied by 10. 10 PPM is lowest PPM “resolution”. Example: If “5” is visible, 5×10 PPM = 50 PPM being detected.
2. “X100” (High Concentration Scale (100 To 10,000 PPM))-To change to this scale, press the YELLOW “H/L Key”. Any value shown should be multiplied by 100.

TEST THE LSCG

• a. I n an area known as free of combustible gas, test the LSCG to confirm it is working properly.
• Use a combustible gas (such as an unlit lighter), to confirm the LSCG detects gas.
• If combustible gas is not detected with this simple test, do NOT proceed with testing for combustible gas on the jobsite.
• If a defective LSCG is still under warranty, return it to the place of purchase for replacement or refund.

SEARCH FOR GAS LEAK(S) ON THE JOBSITE

• a. In a piping system, slowly trace the system with the end of the LSCG. Stop at pipe joints (where leaks typically occur) to monitor gas levels.
• b. If using the default X10 Concentration setting, the LSCG will alarm as low as 10PPM (or 100 PPM if using the X100 setting).

CLOSELY MONITOR DISPLAY READINGS OR ALARMS

• a. As gas concentration levels change, so will:
• PPM Display (Always ON)- 1,000 PPM (when using the LOW Concentration Setting) Or 10,000 PPM (HIGH concentration Setting) is the maximum concentration that can be displayed for any gas the LSCG will detect.
• LEL Display (Always ON)- 20 % is the maximum concentration the LSCG will display.
• Audible Alarm Frequency- When ON this alarm increases in step with gas concentration.
• Vibration Alarm Frequency- When ON this alarm increases in step with gas concentration.

WHEN GAS LEAK DETECTION IS COMPLETE

• a. Press the ON/OFF key to turn LSCG OFF and store it in the protective case provided.

APPENDIX

LOWER EXPLOSIVE LIMIT (Defined)
The MINIMUM concentration of a combustible gas needed to support its combustion in air is its LOWER EXPLOSIVE LIMIT (or “LEL”). And, the LEL varies from gas to gas, but most flammable gases are usually less than 5% by volume (but nearly never greater than 20%). See the full LSCG Owner’s Manual at cpsproducts.com for more information.

NON EXPLOSIVE / EXPLOSIVE RANGE DIAGRAM FOR METHANE

BELOW a specific LEL for a combustible gas, the air/gas mixture is too “lean” (not enough gas is present to burn). See the above visual diagram that applies to Methane only.

EXPLANATION & EXAMPLE OF PPM AND LEL FOR METHANE GAS

EXPLOSIVE RANGE (Defined)
The range between the LEL and UEL where a particular gas will combust.

UPPER EXPLOSIVE LIMIT (Defined)
The maximum concentration of a gas that will burn in air is the Upper Explosive Limit (UEL). ABOVE the UEL value for a particular gas, there is too much gas present and not enough air (oxygen) so, the mixture is too “rich” to burn.
