4.0 Installing the Air Sentinel

The kit includes the Air Sentinel, ten locking nuts and a top hole plug.

4.1 Installing the Top Hole Plug (25359)

Tools Required:

⁄

" or 10mm nut-driver or socket wrench

As the Air Sentinel has an integral vent the Cyclops Vent was removed.

This hole must now be plugged. A stainless steel plug is provided.

This has rubber seal that goes on the outside and washer and nut

on the inside.

The plug needs to be sealed until there is no gap between the top cap

and the enclosure but do not over tighten.

4.2 Install the Air Sentinel

Tools Required:

11mm (or

⁄

") combination wrench and socket wrenches

The Air Sentinel is sent with 10 Stainless Steel locking nuts. These are

a combination of a nut, washer and lock to make installation easier.
When installing the din rail needs to be installed at the top left side

tightened with two nuts.
After installing, check all 10 nuts one last time to ensure all are tight.

4.3 Air Vent Connection

Tools Required:

Knife or Scissors
The vent from the top of the optics assembly previously had no final

connection. A check valve was used to prevent water from entering

the enclosure.
This vent must now connect to a fitting on the Air Sentinel through the

same check valve. The tube is shortened by about 50-60mm. This tube

will be placed on the output of the check valve to allow for the optics to

vent through Air Sentinel.

4.4 Wiring the Air Sentinel

Tools Required:

Small flat blade screwdriver
Each of the power terminal

blocks can be removed

for ease of use. Be sure to

tighten these locks after

connections are finished.
As stated on the label, Mains

power is applied to the upper

set of terminals and the

connection to the DIN rail

must be made to the lower

set of terminals.

4.5 Chassis Replacement

Refer to section 1.1 and reverse all the electrical connections. When

replacing the chassis, ensure there are no interferences, that the finger

guards are in place and there no pinched wires.
This completes the installation. Refer to the Air Sentinel for operation.
