Answer to Question 1

ANS: D
Typically, the pop-off is either a gravity or spring-loaded valve that releases pressures above 2 psig.

Answer to Question 2

ANS: A
Heating the reservoirs of these units can increase humidity content but is not recommended be-cause the resulting condensate tends to obstruct the small-bore delivery tubing to which they connect.
