Connect field-supplied
equalizer tubing from
the TEV into the
suction line a short
distance downstream
of the bulb.
External equalizer
line requires field-
supplied tubing
from the 1/4” ODF
fitting on the valve
and connected
into the suction
line preferably at
location “X” down-
stream of the
TEV bulb. If “X” is
not possible,
location “Y” is
acceptable as long
as pressure is
essentially the
same as at “X”.
