A fleet garage technician holds only the vehicle air conditioning certification issued under Section 609 and is asked to recover the charge from the shop's own rooftop air conditioner. What does that credential allow?
Correct Answer
A) It does not cover the rooftop unit, which requires Type II certification
The vehicle program and the stationary program are separate, with separate exams and separate credentials. A technician certified to service air conditioning in cars and light trucks has demonstrated nothing about high-pressure stationary appliances, and the credential does not reach them. Recovering from the shop's rooftop unit calls for Core and Type II certification, and for recovery equipment certified for appliances other than small appliances.
Why This Is the Correct Answer
Section 609 certification covers motor vehicle air conditioning work only. Stationary equipment such as a rooftop air conditioner falls under the stationary technician program, where a high-pressure appliance requires Type II certification. Holding one credential says nothing about the other, and a technician needs the section that matches the equipment in front of him.
Why the Other Options Are Wrong
Option B: It covers any appliance as long as the charge is recovered into a cylinder
Recovering into a cylinder is a practice requirement, not a substitute for certification. The technician still has to hold the section that covers the appliance.
Option C: It covers the rooftop unit because both use the same recovery equipment
The two programs use different recovery equipment standards, and in any case the tools a job uses do not decide which credential it requires.
Option D: It covers the rooftop unit because the shop owns the equipment involved
Ownership of the equipment changes nothing. The certification requirement follows the person doing the work and the class of appliance being opened.
Memory Technique
Cars have their own rulebook. Bringing that card onto a roof does not change which book you are standing in.
Reference Hint
Motor vehicle air conditioning certification does not authorize work on stationary appliances, which require the matching Section 608 section.
