2.3 Humidifi er installed on a horiz. support
If the humidifi er is installed on a horizontal support:
1.
the fi ll/drain lines are connected through the rear panel;
2.
the power cable gland is installed on the rear panel.
To connect the fi ll/drain lines:
A

Attach the piping to the quick couplings so as to connect the fi ll and
drain valves.
1. press the quick coupling locking ring;
2. insert the pipe.
2.4 Humidifi er mounted on the wall
If the humidifi er is wall-mounted, proceed as described in the previous
paragraph to remove the covers, and then install:
1. the fi ll/drain lines, connected through the bottom panel;
2.
the power cable gland, on the bottom panel.

2.5 Feedwater

To ensure correct operation, humiSonic requires the use of demineralised
water, with the chemical and physical characteristics specifi ed in the table.
To ensure these water quality values, a reverse-osmosis demineralisation
system is typically used.

To avoid excessive oversizing of the reverse osmosis system, it is
recommended to avoid sizing the system based on instant fl ow-rate.
Rather, an expansion vessel should be installed between the water
treatment system and humiSonic.
The sizing calculations need to consider discontinuous water
consumption, comprising the following stages:
•
fi lling (fi ll valve open);
•
production (fi ll valve closed);
•
washing (fi ll valve open).
The table below suggests the minimum sizes for connection to a generic
reverse osmosis system.
Mod. Storage Total expansion l (gal) vessel volume
l (gal) (pre-charge 1.5 bars/22 psi)
UU02 2,8 (0.62)
UU04 3,6 (0.79)
UU06 4,4 (0.97)
UU08 5,2 (1.14)
If no storage vessel is available, the reverse osmosis system must
guarantee the instant fl ow-rate of the fi ll SV, equal to 0.6 l/min (0.16 gpm)..
Connecting humiSonic to the Carel WTS Compact
The Carel product range includes a series of reverse osmosis systems
("WTS Compact") designed to produce water according to the feedwater
specifi cations and optimise connection to and operation with humiSonic
(see manuals +0300017 and +0300019). All WTS Compact systems (P/N
ROC%) always come with an expansion vessel, that maintains the required
pressure in the circuit downstream. Operation of the system is managed
by pressure switches in the outlet circuit. The basic rule for connection
to the humidifi er is that the water contained in the expansion vessel
must be suffi cient to satisfy initial fi lling and, if necessary, the washing
cycle, while the WTS production time must cover humiSonic production
demand and fi ll the vessel as quickly as possible.
The table below suggests the water consumption values and connections
for all sizes of humidifi ers.

UU06 6 (1.59) 2,4 (0.53)
UU08 8 (2.11) 3,2 (0.70)
(*) Water consumption during the washing cycle is calculated based on the
default settings (1 wash every 12 h, lasting 1 minutes, which ends by totalling
fi lling and emptying the volume of the tank). Consumption depends on the
fi ll solenoid valve fl ow-rate, which is 0.6 litres/minute (0.16 gpm). The duration
and frequency of the washing cycles are parameters that can be set by the
user, and these have a signifi cant impact on the sizing of the WTS system.
