Uniflair LE Accessories Manual64

NOTE: Do not place the positive pressure sensor head under the raised floor where the airflow velocity is high.

For example, directly beneath the unit. The recommended position for the pressure sensor head is 3–4 m (10–

13 ft.) away from the unit.

2. Fasten the mounting clamp to a raised floor post.

3. Ensure that excess tubing is carefully secured. Avoid sharp bends or kinks in the tubing.

The above-floor pressure sensor can be installed in the port located at the bottom-right corner of the Uniflair

unit.

1. Using a standard screwdriver, pry off the cover on the sensor port.

2. Route the tubing through the cooling unit, neatly coiling any excess tubing.

3. From inside the unit, attach the sensor head to the port, then fasten the fitting into the port from outside

the unit.

If the unit is not in the air-conditioned room, the tubing can be installed using the wall mounting bracket

provided with the kit.

1. After determining an appropriate location for the sensor, drill a hole through the wall and mount the

sensor bracket.

2. Tubing can be installed behind the wall and through the hole, then attached to the sensor.

WARNING

HAZARD TO EQUIPMENT OR PERSONNEL

Verify that the area behind the wall is free of electrical wires or piping before drilling holes

into the wall.

Failure to follow these instructions can result in death, serious injury, or equipment

damage.
