Water Connections; Warnings; Water Connections (Parts Not Included); Humidifier Installed On A Horizontal Support - Carel humiSonic User Manual

ENG
CAUTION: before proceeding with the water connections,
make sure that the humidifier is not connected to the mains
power supply.
NOTICE
: for the Australian market and to comply with Watermark
requirements, a watermarked approved dual check valve shall be installed
in the supply line to the humidifier when connected to potable water.
Should on the other hand the humidifier be fed with treated water from a
Carel reverse osmosis system connected to potable water, the dual check
valve shall be installed in the supply line to the reverse osmosis system.

4.1 Warnings

1. Only use demineralised water. Install a shut-off valve for each
humidifier. Allowable water pressure: from 1 to 6 bars (from 14.5 to
87 psi);
2. The pipes/hoses and connections between the pipes/hoses in
contact with demineralised water and the humidifier must be made
from resistant material suitable for this use (e.g. PVC or stainless steel):
nominal pressure ≥ 6 bar (87 psi), working temperature at least 1 to
40°C (33.8 to 104°F);
3. The water lines must not be fouled by dust particles or other
substances. Carefully clean the lines before connecting to the
humidifier;
4. All humiSonic ultrasonic humidifiers are supplied with quick
couplings for connecting the fill hose OD/ID = 8/6 mm (OD 5/16",
ID 15/64").

4.2 Water connections (parts not included)

• Install a manual shut-off valve upstream of the installation (so as to
shut off the feedwater supply); the valve must be suitable for use with
demineralised water.
• Install a mechanical filter (10 μm) downstream of the manual shut-off
valve to trap any solid impurities; the filter must be fitted with shut-off
devices to allow cleaning.
NOTICE:
• When installation is completed, flush the supply hose for around 30
minutes by piping water directly into the drain, without sending it into
the humidifier. After installing the valve, flush with water to eliminate
any processing residues and oil and prevent them from entering the
humidifier;
• the drain hose must have a minimum inside diameter of 6 mm (15/64");
it must not have any bends that block water flow; the drain line must
comply with national and local standards in force and must include a
funnel to ensure interruption of continuity and a drain trap to prevent
the return of bad odours. The end of the line must have a downwards
slope to assist drainage;
• do not obstruct the atomised water outlet or air intake openings;
• if there is the risk of the feedwater freezing, insulate or using heating
wires on the water pipes.
water drain
NOTICE The drain water must be able to flow freely.

4.3 Humidifier installed on a horizontal
support
If the humidifier is installed on a horizontal support:
1. the fill/drain lines are connected through the rear panel;
2. the power cable gland is installed on the rear panel.
To connect the fill/drain lines:
A
B
A. Unscrew the screw and remove the right-side panel;
B. Cut the knock-outs to make openings for the fill/drain lines;
WARNING: cutting hazard. The openings have sharp edges.
Wear personal protective clothing.
NOTICE
: outside diameter = 8 mm (5/16"), inside diameter = 6 mm
(15/64").
C. Attach the piping to the quick couplings so as to connect the fill and
drain valves.
1. press the quick coupling locking ring;
2. insert the pipe.
4.4 Humidifier mounted on the wall
If the humidifier is wall-mounted, proceed as described in the previous
paragraph to remove the covers, and then install:
1. the fill/drain lines, connected through the bottom panel;
2. the power cable gland, on the bottom panel.
