Hints for Exhaust Duct Installation

The following rules must be strictly followed to obtain optimal air extraction result:

 Keep expansion pipe short and straight.

 Suggest to use φ 150*2m expansion pipe for the best performance.

 When installing expansion pipe, always pull it tight to minimize loss on hood efficiency caused by

pressure.

 Failure to observe and follow these instructions, cooker hood performance will be reduced and

noise level will be increased.

 Installation work must be carried out by a qualified electrician or competent person.

 Do not connect the ducting system of the hood to any existing ventilation system which is being

used by any other appliances, such as warmer tube, gas tube, hot wind tube.

 The angle of the bend of the expansion pipe should not less than 120°; you must direct the pipe

horizontally, or, alternatively, the pipe should go up from the initial point and led to an outer wall.

 After the installation, make sure that the cooker hood is level to avoid grease collection leak out

from one end. See FIG 11.

 Ensure the expansion pipe selected for installation complies with relevant standards and is fire

retardant.
