What must the equipment owners/operators include in recovered refrigerant records for equipment with refrigerant charges that range from 5 to 50 lbs.?

• The quantity of refrigerant (by type) added or recovered from disposed appliances each year and quantity of refrigerant (by type) sent from reclamation or destruction.

• The quantity of refrigerant (by type) added or recovered from disposed appliances in each calendar month and quantity of refrigerant (by type) sent for reclamation or destruction.

• The type of refrigerant, the amount added for seasonal variance, the amount added to a new unit, recovered from disposed appliances in each calendar month and quantity of refrigerant (by type) sent for reclamation or destruction.

When recovering refrigerant from a medium-pressure system with more than 200 lbs. Of refrigerant, recovery to a level of:

• 0” Hg

• 4” Hg

• 10” Hg

• 15” Hg

A high-pressure appliance containing less than 200 lbs of an HCFC or HFC refrigerant must be evacuated (recovered) to a level of:

• 15 inches of vacuum

• 10 inches of vacuum

• 4 inches of vacuum

• 0 inches of vacuum

A high-pressure appliance containing 210 lbs. Of R407C refrigerant must be evacuated (recovered) to a level of:

• 15 inches of vacuum

• 10 inches of vacuum

• 4 inches of vacuum

• 0 inches of vacuum

Proper recovery techniques begin with the use of appropriate recovery equipment that has been certified by:

• EPA only

• Manufacturers approved by UL

• EPA approved laboratory

• EPA field supervisors
