Modification kit, water system
EUQZ-03 once-through water d = 2
The modification kit consists of a kit of humidifier fill in
aluminium mounted in cassettes made of stainless steel
and a replacement kit of distribution tubes. A further
supply unit containing one/two solenoid valves with
automatic pulsing of the water flow when the humidifi-
cation signal is given. When no signal is given, the sole-
noid valve/s is/are closed.
This means that no external solenoid valve is requi-
red.
If such a valve is present, it may be removed. If this is
not practically possible, and if the existing solenoid valve
must remain in place, the humidification signal must be
sent to both the old solenoid valve and the one or more
new ones.
The new distribution tubes have fewer holes and can
be identified by a notch, see figure 3.
Replace components as shown in figures 1 and 2.
