Safety Considerations
AEC/Application Engineering NEC Series central chillers are designed to provide safe and
reliable operation when installed and operated within design specifications, following national
and local safety codes. To avoid possible personnel injury or equipment damage when installing,
operating, or maintaining this equipment, use good judgment and follow these safe practices:
; Follow all SAFETY CODES.
; Wear SAFETY GLASSES and WORK GLOVES.
; Use care when LOADING, UNLOADING, RIGGING, or MOVING this equipment.
; Operate this equipment within design specifications.
; OPEN, TAG, and LOCK ALL DISCONNECTS before working on equipment. It’s a good
idea to remove the fuses and carry them with you.
; Make sure the chiller is properly GROUNDED before switching on power.
; When welding or brazing in or around this equipment, be sure VENTILATION is
ADEQUATE. PROTECT adjacent materials from flame or sparks by shielding with sheet
metal. An approved FIRE EXTINGUISHER should be close at hand and ready for use if
needed.
; The refrigeration system can develop refrigerant pressures in excess of 500 psi. DO NOT
CUT into the system without first relieving pressure.
; Do not jump or bypass any electrical safety control.
; Do not restore power until all tools, test equipment, etc. have been removed and the panels
replaced.
; Only PROPERLY TRAINED personnel familiar with the information within this manual
should work on this equipment.
