•

EAN: 7350070006444

General

Installation and commissioning must be carried out by a person with sufficient professional knowledge to ensure good function. Suitable location is in a storage room, above the ceiling in a hall or similar space. The unit can be mounted horizontally, on the ceiling or on a wall. The unit must be placed in a warm space.

Electricity connection

The unit is internally pre-wired and comes with a cord rack (approx. 2 m) with a plug. The plug is connected to an earthed socket 1×230 V, 10 A slow-blow fuse. The post-heating battery and sensor are also pre-wired at the factory. The control panel is connected with a quick connector to the control cable. A 15 m cable between the unit and the control panel is included.

Assembly

The unit can be installed in the ceiling, suspended ceiling, wall or floor. As the unit has an inspection hatch on both sides, a flexible installation is possible.

Suspension angles are supplied and placed on the side that is mounted on the ceiling, wall or floor. Hinge angles for opening hatches are mounted on the inspection side.

See the dimensional drawing above for the outer dimensions of the suspension angles and c/c dimensions for screw holes. Fixing screws not included.

Connecting the cooker hood

If no cooker hood is connected, an insulated base must be placed on the unit's support for the cooker hood, dim 125mm. The cooker hood is fitted with an external electrical connection for lighting and any electronics.

The capacity of the unit is increased by closing terminals 1 and 4 on the unit's circuit board by a potential-free relay in the cooker hood.

Simplifies ducting on multiple levels.

When using a cooker hood supplied by Acetec AB

The cooker hood is equipped with connectors, adapted for A30T and A60T.

For A50CS applies:

Remove the white plug for 1x230V electrical connection and connect the cable to 1x230V with a plug or fixed connection. Electrical connection for 230V is made externally and not in the unit. Remove the blue plug and connect one wire to terminal 1 and the other wire to terminal 4 on the unit's circuit board.

Cable and connector between cooker hood and unit not included.

Commissioning

When commissioning, air flows must be adjusted so that the exhaust air flow is 10-15% higher than the supply air flow (negative pressure) for safe operation. Applies to all operating modes.
