The humidifier shall be connected to purified water mains with stable pressure of 1 bar ± 0.2 bar.
The conductivity of the water shall be no more than 10 µs/cm. Use ¼” PU pneumatic hose to
connect the humidifier inlet to a purified water source.
The USB is used to update software version, update temperature and humidity data for PC
processing. Use Ethernet interface for internet access and remote control or monitoring.
The minimum distance away from the back of the equipment to the wall, furniture or other
installations shall be 300mm!
Voltage, frequency and current for power supply must meet the requirements as designated
on the nameplate! Use power socket matching the power plug of the equipment. Hot
line(L)and neutral line(N)for single phase equipment must not be reversed!

Chapter 2 Installing and Operating 2
The humidifier shall be connected to purified water mains with stable pressure of 1 bar ± 0.2
bar. The conductivity of the water shall be no more than 10 µs/cm.
Tape water, distilled water or purified water of general process with conductive ions (TDS in
general), including contaminant of bacteria, microorganisms and organic substances will
degrade the service life of the piezoelectric element of the humidifier.
Unstable supply pressure will affect water level of the humidifier, thus the hysteresis for mist
generating and humidifier efficiency. The piezoelectric element may be damaged if low water
level triggered from time to time.
Check the function of the water supply float valve and low level switch at 3 months intervals to
avoid overflow, performance of the humidifier and low level protection.
Check and clean the ultra-sonic module at 1week intervals or where necessary so that no dirt
buildup or corrosion occurs.
For normal use, the cover of the humidifier (Fig3-237) shall be kept in place with correct
orientation as designated on the marking, to keep the bath tank clean, smooth flow and
distribution of the humidity mist.
