9.2 Check the condensate drainage with the non-return valve
NOTE! Regularly check the non-return valve and the seal below it for dirt and
blockages.
• Turn the non-return valve (Fig. 3, item 1) anti-clockwise and pull it off in an
upward direction.
• Check the non-return valve for dirt and clean if necessary.
• Check the seal (Fig. 3, item 2) for dirt and clean if necessary.
• Place the seal in the connection of the non-return valve (Fig. 3, item 3).
