Because the infrared humidifier contains flowing hot water, the water pipe must be resistant to heat higher than
90°C. For the unit that uses electrode humidifier, the drain pipe of the condensate water must be able to
withstand

3.6.3 Connecting water inlet pipe of humidifier
Connecting water inlet pipe of infrared humidifier
Requirements for connecting the water inlet pipe of infrared humidifier:
1.To facilitate maintenance, an isolation valve should be fitted to the water inlet pipe.
2.Make sure that the connection of the water inlet pipe is well sealed to prevent leakage.
The infrared humidifier
reserves a copper pipe (OD: 6.35mm), as shown in Figure 3-10
.There is a 1/4” copper nut at the end of the copper
pipe, and the 1/4” × 1/2” conversion copper thread connector has been connected to the copper nut to avoid losing
them. You can also select other connection methods.
Note
Where the main pipe pressure may rise above 700kPa (The main pipe pressure should be between 100kPa ~
700kPa), a pressure reducer should be fitted.
Where the main pipe pressure falls below 100kPa, a water tank and pump system should be used.
Some product may include components required by local codes.
