|
•
|
Make sure the device is not located in areas that contain a flammable mixture of gas and air. Otherwise, an explosion can occur. |
|
•
|
The device is not intrinsically safe. Do not use the device in areas classified as hazardous or locations where explosive concentrations of combustible gases or vapors can occur. |
Failure to follow these warnings can result in serious personal injury or death.
WARNING!
|
•
|
Make sure the device is installed in a clean, dry area that is protected from vibration, including but not limited to a chiller, and heat sources. |
|
•
|
Do not paint the device. Do not paint near any of the sample line inlets. If painting is done near the device, make sure that paint is not deposited on the sample inlet fittings. Paint deposits can prevent correct operation of the device. |
|
•
|
Make sure the sample inlet lines to the device are clean and noncondensing. |
|
•
|
Avoid any installation where condensation can collect. Condensation can clog or block sample lines, which will prevent the device from receiving new or fresh gas samples in the area being monitored. |
|
•
|
Install and maintain end-of-line filters in all sample inlet lines. Refer to End-of-Line Filters. |
|
•
|
The only absolute method of ensuring correct overall operation of a gas detection instrument is to do a check with a known concentration of the gas for which it has been calibrated. Do a calibration check as part of the installation and initial setup. Refer to Initial Setup. Do routine calibration checks thereafter. Refer to Routine Operation. |
|
•
|
Install a circuit breaker for the incoming power connections of the device. Put the circuit breaker in a location that is easy to access and near the device. Clearly mark the circuit breaker as the disconnecting unit for the device. |
|
•
|
Properly vent the exhaust of the Chillgard 5000 system to a safe area. Improper venting of the exhaust can cause serious personal injury or death. Refer to Exhaust Venting or R-Gases. |
|
•
|
To prevent unauthorized or untrained personnel from opening the device enclosure, install a locking mechanism through the metal loop on either latch on the left side of the device (Figure 2 ). |
|
•
|
Perform periodic leak tests on all sample lines. |
Failure to follow these warnings can result in serious personal injury or death.
