Page 14: Performing Leak Test & Insulation
Performing leak test & insulation Leak test LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R410A, it’s responsible of installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 4.1MPa (gauge). - Page 15 5. Select the insulation of the refrigerant pipe. • Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. • Indoor temperature of 30°C and humidity of 85% is the standard condition. If install in a high humidity condition,use one grade thicker insulator by referring to the table below. If installing in an unfavorable conditions, use thicker one.
- Page 16 Performing leak test & insulation Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU • You can contact the gas side and liquid side pipes but the pipes should not be pressed. Insulation Insulation • When contacting the gas side and gas side pipe, use 1 grade thicker insulator.
