Figure 30 Duct Installation Kit
The following numbers refer to Figure 30 above:
Supporting bar (not included in the kit for HMT315)
Probe attaching part (to be fixed with the supporting bar)
NOTE
When the temperature difference between the duct and the air outside the
duct is significant, the supporting bar must be installed as deep in the
duct as possible. This helps to prevent errors caused by heat conduction
in the bar and cable.
