Installation
2.9.1. Installation of the air conditioning pipes
The air conditioning pipe can be connected in three ways, namely - indoor unit condensate drain, inlet pipe of the
electrode humidifier, and the copper pipe connection (pipe and liquid pipe) between the indoor and outdoor unit.
• All the refrigerant pipe joints must be silver-brazed.
• Selected pipe, arranged and fixed in the system, should be evacuated and the refrigerant charging opera-
tion must adhere to the industry standards.
• Design and construction process should take into consideration the pressure drop piping, compression oil
return, reduce noise and vibration.
• Brass need for thermal insulation – When the copper pipe passes through the wall or other obstacles, it
is necessary to avoid direct contact with the walls of the copper tube through the other cushion isolation
measures and prevent dust, water vapor, and solid particles into the copper pipe.
• To ensure the quality of the welding, the use of high silver-based soldering pipe joints is required. Also,
welded line charge nitrogen is needed for the welding process.
Air filters
• On opening the cabinet rear door, two vertical filters can be seen.
• Initially, loosen the screw fixing the filter on the fixing piece. The fixing piece is removed on the filter and taken
out in the same manner under the filter as shown in the following Figure 2-89.
