6.3 Water discharge
Warning:
Water must drain freely! During blow down up to 0,3
litre water per second are being drained. For water discharge,
we recommend installation of a flexible water drain hose.
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.
150 - 300 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.
There is a 3mm-wide crack between the pump drain hose jacket
and the inner surface of the housing drain connection. If water
collects in the base plate, it will flow through this crack into the
drainage system.
