• Route the vent-line piping so that it discharges
outdoors in an area that will not spray refrigerant
on anyone. Position the vent-line discharge at least
15 ft (4.6 m) above grade level and at least 20 ft
(6.1 m) from any building opening. Provide a vent-
line termination that cannot be blocked by debris or
accumulate rainwater.
• Provide a drip leg on the vent line (refer to the
following figure [arrangement for rupture disk relief
piping]). Provide a standard 1/4-in. FL x 1/4-in. NPT,
capped refrigerant service valve to facilitate liquid
removal.
