6.3 Water discharge
Warning: During blow down hot water with a temperature of
about 95°C is being drained. If touched this can cause burns to
the skin.
Warning: Pay attention for free and non-pressure drainage of
the water! During blow down up to 0,3 L/sec are being drained.
For water discharge, we recommend installation of a flexible
water drain hose. Humidifier and wastewater discharge must be
on the same pressure level.
Please note:
• Do not bend the drain hose.
• Install discharge line and drain pipe made from temper-
ature resistant material (to 95° C).
Install water discharge as follows
• Loosely insert a length of 1 1/4 " drain hose, approx.
250 - 1000 mm, into a drain pipe with a minimum inner
diameter of 40 mm and seal with a rubber gasket.
• Fit water drain hose over the pump drain hose and fas-
ten to the housing drain connection.
A grounding clip is fixed on the inner surface of the housing
drain connection. The end of the pump drain hose is pushed into
this clip. During blow-down, the grounding clip is in direct contact
with the water and shunts potential residual electric currents
away from the housing.
