Type I — Small AppliancesQuestion 104 of 240
Which of these is a defining physical feature of a small appliance that distinguishes it from field-installed equipment?
a.It always uses a thermostatic expansion valve
b.Its refrigerant circuit is hermetically sealed and charged at the factory
c.It must be charged by the installer on site
d.It contains between 5 and 50 pounds of refrigerant
Explanation
A small appliance is hermetically sealed and charged at the factory, unlike field-assembled split systems that are charged during installation. This factory-sealed construction, combined with a charge of five pounds or less, is what places it in the small-appliance category. Metering device type and larger charge sizes are not part of the definition.
