Installation
TRANSDUCER PNEUMATIC TUBING
Static Pressure Control Plastic Tubing
(Pneumatic Tubing)
Duct static transducers (all VAV units) and any unit with
an op tion al building pressure control trans duc er, require
pneumatic tubing to be fi eld supplied and in stalled.
Both the duct static transducer (VAV only) and optional
building pressure transducer are mounted behind the
right hand damper door. All wiring from the trans duc ers
is factory installed.
Duct Static Transducer
Plastic tubing (3/16" ID) must be run from the high
pres sure tap of the trans duc er to a static pres sure tap
(fi eld supplied) in the supply duct, located at a point
where constant pres sure is de sired. This is normally
2/3rds of the way down the duct, before the fi rst take
off.
Building Pressure Transducer
Plastic tubing (3/16” ID) must be run from the high
pressure tap of the building static pressure transducer
to a static pressure tap (fi eld supplied), located in the
conditioned space. The tap should be placed in a
location where over pressurization will cause a problem,
for example, in the lobby area where excessive pressure
will cause the doors to remain open. The tap should
never be placed above the ceiling.
Static Pressure Probe Installation
On units with duct static transducers (VAV units) and
any unit with an optional building pressure, a factory
supplied Static Pressure Probe must be fi eld installed at
the top of the rear corner post on the unit -
see Figure.
2-12.
The factory supplied atmospheric pressure probe and
associated mounting hardware are shipped inside the
unit control panel. The hard ware consists of a mount ing
bracket and a short section of pneu mat ic tubing.
The
pneu mat ic tubing must be fi eld in stalled from a factory
pressure tap (next to the mount ing lo ca tion for the
static pres sure probe) to the at mo spher ic pressure
probe (see Installation Instructions, Form XXX.XX-
XX).
If the unit is equipped with both a building pressure
trans duc er and a duct static trans duc er, a “tee” will
be factory installed, and both the Duct Static Pres sure
Transducer and building pres sure will be connected to
the “tee” - both building stat ic pres sure trans duc er and
duct static trans duc er will use the same fac to ry sup plied
at mo spher ic pres sure probe.
The “low” side connection of the
duct static or build ing pres sure trans-
duc ers are shipped with the pneu mat ic
tubing factory in stalled and rout ed, to
the external factory pressure tap.
