NV C-37D Solar Pool Heating Practice Questions - Nevada C-37D Solar Pool Heating Contractor Examination Exam - NV C-37D Solar Pool Heating Practice Questions - Nevada C-37D Solar Pool Heating Contractor Examination Exam

Question 1

Under NAC 624.540(2)(d), which piping is within the Nevada C-37D Solar Pool Heating scope?

Piping that connects solar collectors and heat exchangers used to heat a pool or spa with solar energy The pool's main-drain, skimmer, and return-jet circulation plumbing Potable fixture branches to lavatories and showers Photovoltaic DC homeruns from modules to an inverter

Correct Answer:

Piping that connects solar collectors and heat exchangers used to heat a pool or spa with solar energy

Question 2

What piping material is the usual choice for an unglazed solar-pool collector loop that circulates filtered pool water at about 80°F?

Schedule 40 PVC listed for the temperature and pressure of the pool-solar loop Type M DWV copper used for waste stacks Unlisted thin-wall automotive heater hose as the entire roof run Type K copper with 50/50 lead-tin waste solder

Correct Answer:

Schedule 40 PVC listed for the temperature and pressure of the pool-solar loop

Question 3

Why is Schedule 40 PVC acceptable on a typical unglazed solar-pool loop but not on a glazed potable-DHW collector loop?

Pool-solar water stays near 80°F, while a glazed DHW collector can stagnate well above PVC's temperature rating PVC is listed only for natural-gas service The UPC bans all plastic pipe outdoors PVC cannot be solvent-cemented

Correct Answer:

Pool-solar water stays near 80°F, while a glazed DHW collector can stagnate well above PVC's temperature rating

Question 4

Where should the solar-collector feed tee be taken on an existing pool circulation system?

After the existing filter, so only filtered water enters the collectors On the suction line before the pump, so the pump never sees solar head Out of an unfiltered main-drain branch that C-37D newly installs Out of the automatic chlorinator so chemicals precondition the panels

Correct Answer:

After the existing filter, so only filtered water enters the collectors

Question 5

If the pool already has an automatic chlorinator, where does the solar-collector return rejoin the existing piping?

Upstream of the chlorinator so treated water is not pumped through the collectors Downstream of the chlorinator so chlorine sterilizes the roof array Into the pump suction so the chlorinator never sees solar flow Into a new skimmer that the C-37D contractor installs

Correct Answer:

Upstream of the chlorinator so treated water is not pumped through the collectors
