LOw dEMANd APPLICATIONS
during periods of low demand, the compressor may not reach its normal operating temperature . Sustained
operation at low demand can result in the build up of condensate in the coolant . If this situation occurs, the
lubricating characteristics of the coolant can be impaired which may lead to damage of the compressor .
THE COMPRESSOR SHOULd BE ALLOwEd AMPLE LOAdEd RUNNING TIME OF AT LEAST 10 MINUTES PER HOUR
dURING NORMAL dAILy USE .
