Single point or multi-point purging
Single point purging is the basic setup in the
Danfoss IPS 8 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.
