by purging with zero or a gas with a low PPM oxygen concentration is recommended after the cleaning
process is completed.
Mounting:
The analyzer is approved for indoor as well as outdoor use. However, avoid mounting in an
area where direct sun might heat up the analyzer beyond the recommended operating temperature range. If
possible, install a small hood over the analyzer for rain water drain and to prevent over-heating of analyzer.
Gas Connections:
The Inlet and outlet vent gas lines require 1/8” or ¼” stainless steel compression
type tube fittings. The sample inlet tubing must be metallic, preferably SS. The sample vent line may be of
SS or hard plastic tubing with low gas permeability.
Power: Supply power to the analyzer only as rated by the specification or markings on the analyzer
enclosure. The GPR-1800IS is a two wire loop powered analyzer. The input power must be between 12-24
VDC. The wiring that connects the analyzer to the power source should be installed in accordance with
recognized electrical standards. Ensure that the analyzer case is properly grounded and meets the
requirements for area classification where the analyzer is installed. Never yank wiring to remove it from a
terminal connection.
The two wire loop powered analyzers consume no more than 0.68 Watts of power.
