Maintenance Considerations

notes	If air leaks into the chiller, the corrosion inhibitor is depleted as it reacts with the
notes	air and produces hydrogen. To maintain chiller efficiency and ensure continued
	corrosion protection, the lithium bromide solution must be analyzed
	periodically to determine if corrosion inhibitor and performance additive levels
	are within acceptable limits. This is the most important periodic maintenance
	requirement! A laboratory test is required to determine these levels. Suggested
	intervals for testing are once per year for comfort-cooling applications and
	twice per year for chillers in continuous or critical service. Analysis of the
	refrigerant is also recommended. Consult the chiller manufacturer for specific
	corrosion inhibitor and performance additive recommendations.
