VENT PIPING
As a safety precaution, each system is equipped with
pressure relief valves located on the condenser and on
the evaporator for the purpose of relieving excessive
refrigerant pressure to the atmosphere. Many local
codes require that relief valves be vented to the
outside, and this is desirable installation practice for all
installations. NOTE: Remove plastic thread protectors
from the inside of the valves prior to making pipe
connections. Whenever vent piping is installed, the
lines should be run in accordance with local code
requirements; or where local codes do not apply, ANSI
B9-1 -Sec. 12 code recommendations should be
followed.
Current condenser design incorporates two relief
valves (1 set) with a 3-way shut-off valve separating
the two valves. (See Figure 7). When piping the vent
line to a dual valve set, it may be sized for one relief
valve and piped to both valves. If one relief valve of the
two valve set fails, the shut-off valve may be used to
isolate the faulty relief valve, easing replacement. On

larger capacity condenser designs, two sets of dual
