• Header should be insulated with the insulator in each kit.
• Joints between branch and pipe should be sealed with the tape in-
cluded in each kit.
• Any cap pipe should be insulated using the insulator provided with
each kit and then taped as described above.
Insulate the header using
the insulation
material attached to the
branch pipe kit
as shown in the figure.

Leak test
Leak test should be made by pressurizing nitrogen gas to 3.8
MPa(551.1psi). If the pressure does not drop for 24 hours, the system
passes the test. If the pressure drops, check where the nitrogen leaks.
For the test method, refer to the following figure. (Make a test with
the service valves closed. Be also sure to pressurize liquid pipe, gas
pipe and high/low pressure common pipe)
The test result can be judged good if the pressure has not be reduced
after leaving for about one day after completion of nitrogen gas pres-
surization.
