Note
1. A Φ25 hose clamp is delivered as an accessory to connect the draining pipe.
2. When connecting the draining pipe, make sure that the U bend is installed vertically and the 'U' shape is not distorted, so as to
ensure that the cooling water can be drained immediately and effectively.
 Connecting water supply pipe of infrared humidifier
The water pipes should be connected for the infrared humidifier. To facilitate maintenance, a strainer / non-return
isolation valve is fitted to the supply water pipe. The infrared humidifier water supply pipe reserves a copper pipe (OD:
6.35mm, see Figure 2-20) with a 1/4" copper nut at the end of the pipe. Take out of the 1/4" × 1/2" screw-thread copper
connector from the accessory bag and screw the connector onto the copper pipe. You can also select other connection
modes according to the site condition. Make sure the connection is well sealed to prevent leakage. The pipe pressure
is 100kPa ~ 700kPa.
Where the main pressure may rise above 700kPa, a pressure reducer should be fitted. Where the pressure falls below
100kPa, a water tank and pump system should be used.

Note
Main water supply connections must be made in accordance with local laws and regulations.
