Installation - Yamatake HTY78 3 Series Specifications & Instructions

Installation

Important
1) Select a location where the typical temperature and
humidity of the measured fluid can be sensed and
where the wind speed requirements are met.
2) Make sure that the temperature and humidity elements
are entirely immersed in the measured fluid. Also,
make sure that air can pass over the side of the
sensor.
3) Allow adequate service clearance at the front of the
cover.
4) When installing in steam heating air handling unit,
make sure the steam does not directly expose. (It
may exceed the extreme operating condition.)
5) When inserting the insertion part facing upward,
prevent dew condesation. (The condensated dew will
remain in the fileter cap and measurement difference
will occur until it becomes dried.)
Do not step on the unit.
Mounting 7803 series (duct mounted)
1) Prepare the mounting bracket in advance.
Attach the mounting label at the sensor mounting
position and make a hole in the duct at the point
indicated on the label. Fix the mounting bracket onto
the duct with M4 screws, inserting packing between
the duct and the bracket.
Cover the duct with an insulating material. (If you cover
the duct with an insulating material first, fill the
clearance between the bracket and the duct with the
insulating material after fixing the bracket.)
