Answer to Question 1

The seasonal energy efficiency rating takes into account the cycling of the equipment on and off and is considered to be a better indicator of actual equipment efficiency as compared to the EER.

Answer to Question 2

Never use oxygen or acetylene to pressurize a system. Oil that is in the system will not mix with oxygen or acetylene and may cause an explosion. Use dry nitrogen or carbon dioxide from a tank properly fitted with a pressure regulator. When isolating a section of piping or component of a system, exercise caution to prevent damage and potential hazard from liquid expansion. Always charge refrigerant vapor into the low side of the system. Liquid refrigerant entering the compressor could damage the compressor or cause it to burst. Never service a refrigeration system where an open flame is present. The flame must be enclosed and vented outdoors. If a fluorocarbon refrigerant comes in contact with intense heat, it can produce poisonous phosgene gas.
