Connect the condensate water discharge
There is a condensate water evaporator fitted in the ex-
ternal circuit of the cooling unit. With an enclosure con-
nected, this condensate water evaporator may typically
evaporate condensate water volumes of up to 100 ml/h.
If larger quantities of condensate water are produced, a
condensate water discharge hose may additionally be
fitted. This hose allows condensate water to be routed
out of the cooling unit pressurelessly. A suitable hose is
available as an accessory from Rittal (see section 13
"Accessories").
Please follow the instructions given below:
– The hose must be laid with an adequate and constant
gradient to prevent siphoning.
– The hose must be laid without any kinks.
– If extended, the cross-section of the hose must not be
reduced.
