MSA Chillgard RT - General Warnings and Cautions

General Warnings and Cautions
WARNING
1. The monitor and Relay Module described in this manual must be
installed, operated, and maintained in strict accordance with the
labels, cautions, warnings, instructions, and within the limitations
stated.
2. The monitor must not be installed in outdoor areas or in locations
where explosive concentrations of combustible gases or vapors
might occur in the atmosphere: Class I, Group A, B, C, and D
areas as defined by the NEC. Because the monitor is not
explosion-proof, it must be located in non-hazardous areas.
3. The Chillgard RT Refrigerant Monitor is designed to detect one
particular refrigerant gas or vapor at ambient atmospheric
pressures. The unit will not detect refrigerant gas at elevated
temperatures.
4. High levels of or long exposure to certain compounds in the tested
atmosphere may contaminate the sensor. In atmospheres where
the system may be exposed to such materials, perform calibration
frequently to ensure dependable system operation and accurate
indications.
5. Do not paint the Chillgard RT System. Also, do not paint near any
of the sample line inlets to ensure paint is not deposited on the
sample inlet fitting of the units. Such p
aint deposits would interfere
with the sampling process, whereby a sample of the atmosphere
being monitored is drawn into the Chillgard RT System.
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
installation and as a routine inspection of the system.
7. Perform periodic leak checks on all the sample lines and all flow
system components and fittings of the Chillgard RT System.
8. Use only genuine MSA replacement parts when performing any
maintenance procedures provided in this manual. Failure to do so
may impair instrument performance. Repair or alteration of the
Chillgard RT System, beyond the scope of these maintenance
instructions or by anyone other than authorized MSA service
personnel, 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.
