CONNECTING THE DRAIN TUBE
An open draining system with a 110 mm (4 1/2”) funnel is recommended. The drain tube has an
outside diameter of 33 mm (1 1/3”).
• It is not allowed to make a closed connection!
• Make sure that the tube is not kinked and is sloping downwards to the drain funnel.
• The minimum inside diameter of the sewer pipe needs to be 40 mm (1 1/2”).
• A siphon in the customers sewer is highly recommended to prevent odors from coming out of
the sewer.
• See below examples.
An extraction hood is prescribed when the unit is NOT delivered with the special Fri-Jado extrac-
tion hood mounted on it.
The TDR produces about 10 m³ (350 cf) vapour during a cooking cycle. When placing the rotisse-
rie under an extraction hood, the following guide lines have to be considered:
• The minimum capacity of the extraction hood has to be 800 m³/h (25000 cf/h).
• The extraction hood has to extend minimum by 20 cm (8”) on all sides of the rotisserie.
• The extraction hood has to have a free hight, above the rotisserie, of a minimum of 30 cm (12”).
• The rotisserie has to be accessible for service purposes.
• The extraction hood has to have facilities to drain any condensation, down to a drain.
