FIELD SERVICE GUIDE

The problem most frequently encountered in refrigera- tion systems is liquid water downstream. Most causes of water carry-over can be identified and remedied by using the FIELD SERVICE GUIDE. For further help, contact Deltech.

DANGER

Refrigeration systems can be dangerous. Work on the refrigeration system should be done only by a competent refrigeration me- chanic.

Do not release fluorocarbon refrigerants in- doors or drain liquid refrigerants into floor drains. Refrigerant vapors may accumulate in low places. Inhalation of high concentra- tions may be fatal. All refrigerant must be re- covered per EPA requirements.

Do not smoke while working on the refrigeration system or when a refrigerant leak is suspected. Refrigerant may decom- pose in the presence of burning materials, forming toxic gas or acids which may cause serious injury and property damage.
