2. WATER CONNECTIONS
IMPORTANT:
before proceeding with the water
connections, make sure that the humidifier is not connected to
the mains power supply
.
2.1 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…40°C (33.8…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 φe/φi = 8/6 mm (OD 5/16”, ID
15/64”);
2.2 Water connections (parts not included)
•
Install a manual shut-off valve upstream of the installation (so as to
shut off the water 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.
Important :
•
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 that enter the humidifier;
•
the drain hose must have a minimum internal 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
cables on water pipes.
