Single point or multi-point purging
Single point purging is the basic setup in the
Danfoss IPS unit .
The installation should be done as shown in
fig . 9 on top of the receiver or a float valve . (See
connection locations) .
The supply and drainage are mechanically
controlled, with no special configuration in the
purger control required .
The purger unit is able to handle up to 8 purge
points in total (see fig . 10) .
Separate control of the supply solenoids must be
setup .
This control should be based on a timer and must
be established at site .
N = number of purge points
The solenoid activation control must activate/
deactivate each individual solenoid in a sequence
of 24/N hour (example 3 purge points – 24/3 = 8
hour) .

NEVER HAVE MORE THAN 1 POINT OPEN AT A
TIME.
Always close one valve before opening the
next.
The integrated Danfoss purger control needs
to be adapted to the actual number of purging
points during configuration .
This is done by activating the multipurger
(label y02) and entering the number of actual
purge points in the program . See section
"Programming/configuration" .
Please contact Danfoss for instructions on multi-
point purging activation .
