A drain pan with a drain pipe connected to a sewage system is designed for condensate drainage (fig.6).
While selecting the U-trap dimension type consider the total fan pressure. The U-trap must ensure correct
operation of the ventilation system.
Maintenance means regular preventive measures during operations.
The aluminium ribs and the droplet separator must be cleaned at least once per year by vacuum cleaner
or pressure water flushing. The cleaning periodicity depends on air pollution degree and maintenance
quality of the filters and equipment.
If the internal environment is clean enough, the cleaning may be performed more seldom, as required.
The U-trap maintenance includes regular control of water level and sufficient U-trap clearance.
Warning! While cleaning the ribbed battery be careful not to damage the ribbed surface.
