Condensate pump SI 30
The self-priming condensate pump is factory-connected to the top of the unit as far as the hose connection spigot for the on-
site condensate pressurised line.

Flow volumes and limits of use
The achievable flow volume depends on the delivery height and length of condensate hose connected. The volume of con-
densate rises and the possible delivery height of the pump falls with extreme air humidity and/or very low system temperat-
ures. Therefore set up the alarm contact of the float switch to stop dehumidification (e.g. by closing the cooling valve).
Note the following limits of use for max. permitted cooling conditions (CHW 6/10 °C with inlet air temperature 27°C / 60%
rel. humidity):
Model 85: Max. permitted delivery height with a 5 m hose length: 3 m
Model 96: Max. permitted delivery height with a 5 m hose length: 2 m
More powerful condensate pumps are available on request if the permitted flow rate is continually being exceeded.
