1. Each instrument described in this manual must be installed,
operated, and maintained in strict accordance with its labels,
cautions, warnings, instructions, and within the limitations stated.
2. These monitors must not be installed in outdoor areas or in areas
or locations where explosive concentrations of combustible gases
or vapors might occur in the atmosphere: Class 1, Group A, B, C,
and D areas as defined by the NEC. Because the monitors are not
explosion-proof, they must be located in non-hazardous areas.
3. The Chillgard LS Refrigerant Monitor is designed to detect
refrigerant gases in the air. It cannot measure the concentration of
these gases in a steam type atmosphere.
4. As with all gas detection instruments of this type, high levels of or
long exposure to certain compounds in the tested atmosphere
contaminate the sensor. In atmospheres where the monitor may be
exposed to such materials, calibration must be performed
frequently to ensure that system operation is dependable and its
indications accurate.
5. The Chillgard LS Refrigerant Monitor must not be painted.
Painting will interfere with the sampling process of the instrument.
If painting is being done in an area where the instrument is located,
care must be exercised to insure that paint is not put or splashed
on the instrument.
6. The only absolute method to assure the proper overall operation
of a gas detection instrument is to check it with a known
concentration of the gas for which it has been calibrated.
Consequently, a calibration check must be included as part of
the routine inspection of the system.
7. The sensor is a sealed unit. Do not attempt to modify or adjust the
sensing cell.
8. Use only genuine MSA replacement parts when performing any
maintenance procedures provided in this manual. Failure to do so
may seriously impair instrument performance. Repair or alteration
of the Chillgard LS Refrigerant Monitor, beyond the scope of these
maintenance instructions or by anyone other then an authorized
MSA service person, could cause the product to fail to perform as
designed, and persons who rely on this product for their safety
could sustain serious personal injury or death.
9. Ensure that the Chillgard LS Refrigerant Monitor is installed in a
clean and dry area as possible.Install splash or rain shields on the
instrument to keep water and other contaminants away from the
instrument. If you fail to follow this warning, equipment damage
can occur.
