When configuring wet film humidification, you need to prepare a hose clamp and the above-mentioned water inlet
hose, connect with the water inlet solenoid valve, and tighten as shown in Fig. 2-5-3.
Where the main pipeline pressure may exceed 700kPa, a pressure reducer should be installed. Where the main
pipeline pressure is lower than 100kPa, there should be a collection tank and a water pump system.
Note
The main inlet pipe must be made in accordance with local regulations.

(8) Nitrogen filling
Connect the pressure gauge and the nitrogen cylinder at the needle valve of the indoor unit liquid pipe and the
exhaust pipe with a refrigerant hose, open the pressure reducing valve on the nitrogen cylinder, and fill the needle
valve on the suction and exhaust pipe with 3MPa nitrogen at the same time, and keep the pressure for 24 hours.
There should be no decrease in system pressure when the ambient temperature is similar before and after the
pressure holding.
Note
If the pressure value drops, you must use soapy water or a halogen leak detector to find and repair the leak.
