A leak has been found on a large low-pressure chiller that falls under the leak repair provisions. Within what period does the rule expect that leak to be repaired?
Correct Answer
C) Within thirty days of the date the leak was found by the servicing technician
Once a leak has been identified on an appliance covered by the leak repair provisions, the clock starts on the day of discovery and the owner has thirty days to complete the repair. Extensions exist for specific situations, such as equipment that has to be shut down at a time of year the plant cannot manage, but the base period is thirty days. Nothing in the rule allows a leak to be logged and left until the next season.
Why This Is the Correct Answer
The repair period runs from the date the leak is discovered, and it is thirty days. That period is short on purpose, because refrigerant continues to escape and moisture continues to enter for as long as the leak is open. The owner is the party responsible for meeting it, and the dates of discovery and repair both go into the service record.
Why the Other Options Are Wrong
Option A: Within seven days of the date the leak was found by the servicing technician
A week would be unworkable for equipment that often has to be scheduled around a plant's load, and no such period appears in the rule.
Option B: Within ninety days of the date the leak was found by the servicing technician
Ninety days is far longer than the rule allows and would let a chiller lose a large share of its charge before anyone acted.
Option D: Within one year of the date the leak was found by the servicing technician
A year is roughly a full cooling season. Allowing that would defeat the purpose of having leak repair provisions at all.
Memory Technique
One month to fix it. Thirty days from the day you found it, not the day you got around to it.
Reference Hint
Leaks on appliances covered by the leak repair provisions must be repaired within thirty days of discovery.
