VenkonAssembly, installation and operating instructions356.5.7 Condensation connection6.5.7.1 Condensation drain with natural gradientIt is essential that a condensation drain is connected and appropriate fixed to a Venkon condensation drain connector (drainsize 15 mm). Ensure that the gradient is at least 1 cm/m, without restrictions and without rising sections of pipe (in accord-ance with DIN EN 12056: formerly DIN 1986-100) to ensure the drainage of condensation from the basic unit. Take into ac-count all applicable regulations, such as the use of a ball trap, when connecting the condensation line to the sewer system.Protect the trap from drying out. The suction effect of the fan on the condensation drain neck could otherwise producetroublesome odours. Consider using water vapour-impermeable insulation depending on the pipe material used for the con-densation drain. You will need a condensation pump (optional accessories) should a natural gradient be impossible on site.This is used to pump the condensation into higher collection or drainage equipment. When delivered, the condensation pumpand float switch is factory-fitted to the unit.Condensate drain connectionINCORRECTTrap1cm/m50 mmFig. 24: Correct condensation drainage6.5.7.2 Condensation drain via condensation pumpThe water is drawn off by the condensation pump and discharged along a hose (supplied loose) connected on the pressureside. Depending on conditions on site, the water can be discharged into drainage lines, possibly with a trap connection.In the event of a fault with the condensation drain, the water level will continue to rise until the float switch triggers analarm contact. The contact can be analysed by external signalling devices.We would recommend automatically terminating cooling operation, possibly with a shut-off valve, if the alarm contact istriggered to prevent the condensation tray from overflowing.
