Medium size crosshead screwdriver for mounting screws and lid screws.
Small slotted screwdriver for screw terminals.
Drill with 3.5 mm (0.14 in) and 13 … 15 mm (0.51 … 0.59 in) bits for making the installation holes.
Tools for cutting and stripping wires.
Select an installation location for the transmitter on the duct surface and drill a Ø 13 … 15 mm (0.51 … 0.59 in) hole for inserting the probe.
Push the probe through the hole on the duct until the transmitter body meets the duct.
Attach the transmitter body to the duct with 2 × Ø 3.5 mm (0.14 in) screws.
Check that the insulation
ring sits tightly over the installation hole. If the duct has a negative pressure,
external air can be drawn into the duct and affect the measurement if the installation
hole is not sealed tightly.
Optional: Drill a second hole for reference measurements approximately 30 cm (12 in)
from the transmitter installation hole. See Figure 1.
Open the 2 captive screws on the transmitter body and remove the lid.
Attach the input/output wiring to the screw terminals on the transmitter component
board. See Wiring. Tighten cable glands firmly after wiring.
