Product description

The EKF EC kitchen extract fan is suitable for continuous running at 120°C in-duct air temperature. It

can be mounted indoors or outdoors and controlled using the 0-10V potentiometer included.

Installation

The EKF EC kitchen extract fan is designed as a kitchen extract fan to be positioned between lengths of

ducting.

Short duct runs terminating close to the fan (i.e. within 1.5m) must incorporate suitable guards unless the

fan is mounted higher than 2.1m above the floor.

Position the fan at the highest point on the system with both ducting runs sloping downwards from this

point.

In circumstances where an excessive amount of moisture is present in the air then a condensation trap

should be installed.

When siting the appliance, ensure that there is sufficient space to allow access for any servicing and

maintenance.

The EKF EC kitchen extract fan is supplied with 3 x optional discharge positions. Before installation,

consideration needs to be given to which discharge outlet is required. The discharge panel and 2 x

access panels are interchangeable to suit the installation.

It is recommended that duct connections to the unit are made via flexible connectors, (see accessories

list).

Mounting the unit

If mounting the unit outdoors:

the unit MUST be installed with a weather roof fitted (see accessories list);

it is suggested that the unit is mounted at least 150mm off the floor surface.

If suspending the unit, it is recommended that the unit is supported underneath. The M6 nutserts that are

fitted to the framework can be used to fix supports. Take care not to obstruct the access panel. Vent-

Axia supplies a mounting feet kit, (see accessories list).

operation and stay off when there is no power to the motor. In fault condition, the LED will flash in

multiple sequences. Please refer to Vent-Axia Technical Support for more information should this occur.
