Leak Test
Testing pressure for water pipe should be greater than 1.25 times the working pressure, and should not be less than
0.6MPa. Piping system is considered leak free if pressure drop is less than 0.02MPa after 5 minutes of pressure test.
Water pressure test should not be carried out at ambient temperature lower than 5˚C. Pressure gauge should be
well-calibrated with step precision of not less than 1.5; full scale value should be 1.5 to 2 times the biggest tested pressure reading.
During water leak test, water should be added gradually from lower side of the system until it reaches tested pressure.
Air vent should be purged to release trapped air. Stop water pump and inspect for pipe leakage. Do not repair leakage
under pressurized piping system.
Clean the piping system thoroughly after the water leak test (Equipment must be isolated), until the drained water is
free from dust, iron and other foreign particles.
Electrical Installation
Electrical installation should be done according to the local codes and regulations. Unit should be installed by qualified
personnel. Voltage tolerance should be kept at rated voltage ±10%. Phase imbalance must not be greater than 2%.
Communication bus between control modules and wired controllers shall use no less than 0.25mm2 Shielded Twisted Pair
cable size. Do not install data cable alongside the power cable, contactors, circuit breakers, inverters and etc to avoid
electromagnetic interference. Cable connections must be done using end connectors.
