The supplied T-strainer should be used to prevent clogging of the instrument. ¼” quick
connect fittings are supplied on the T strainer. If a pipe fitting change is required, this
change should be made at the T-strainer. Opaque tubing should be used if the tubing will
be exposed to sunlight, to prevent algae growth. Please note that the supplied connectors
are compatible with ¼” O.D. semi-ridged or ridged tubing.
The instrument is equipped with an internal cabinet drain (vent) to prevent damage in the
event of a tubing failure.
The drain tubing connects to a hose barb. The rated tubing size is ½” ID tubing. It is
recommended that opaque tubing be used to prevent algae growth. Keep this tubing as
short as possible. This drain must be kept open to the atmosphere.
