Part AC5005 is a flange with compression fitting that is designed to hold the probe of

the HF4 type D when mounted through a wall (see Accessories). The HF4 does not

require any additional support. The AC5005 allows easy installation and removal of the

HF4.

Mounting position of the enclosure

Mounting hardware

Method 1: The HF4 is supplied with 2 screws, 2 drywall anchors and two

rubber washers. The base of the enclosure has 2 screw-wells (see drawing)

that are normally closed at the bottom. Use the template provided with the HF4

to drill mounting holes in the wall and insert the drywall anchors. Place a

rubber washer on each screw. Insert a screw in each well and push to open

the bottom of the well.

Method 2: When a DIN-rail (35 mm / 1 3/8 “) is available use part AC5002 (not

included). This is a DIN-rail mounting kit consisting of 2 clamps that attach to

the back of the enclosure with the screws provided.
