Connecting the feed hose
Caution!
The feed hose must be connected to the boiler
in such a way that a constant slope is main-
tained, and without any loops or kinks in the
hose to ensure that condensate can flow unob-
structed into the pump.
• Determine the required length of the hose.
• When shortening the hose, allow a min. of 10 mm extra
length for the insertion depth of the hose in the
pump‘s cover.
• Rotate the non-return valve (1) one quarter turn to the
left (anticlockwise) in order to open the cover (2) on
the pump.
This unlocks both the cover and the return valve.
• Pull off the cover and return valve by lifting them
upwards.
