Procedure
Step 1 Manually open the chilled water valve.
Step 2 Raise the water pressure in the chilled water pipe to 0.8 MPa. If no leakage occurs
after 30 minutes, retain the pressure for 24 hours. The expected result is that the
pressure drop is less than 0.01 MPa and the pipe does not leak. Then, release the
pressure in the pipe.
Step 3 Open the exhaust valve or drainage valve to drain water from the pipe to the
water pan for pressure relief.
Step 4 Close the exhaust valve and drainage valve.
Step 5 Manually close the chilled water valve.

If the leakage test has been done with nitrogen, skip the test with water.
Open the exhaust valve of each heat exchanger to exhaust nitrogen onsite.
Ensure that the indoor temperature is always above 0°C during the leakage
test with water, otherwise, the pipes may experience frost cracks. If the indoor
temperature is below 0°C, take anti-freezing measures for the pipes.
Connections of all power cables, control cables, and ground cables must
comply with local electrical regulations, and the cable specifications should
comply with local cabling specifications.
For details about the maximum current, see the nameplate of the unit.
Check that the input voltage and frequency of the active power supply meet
the requirements of the unit.
Only trained and qualified personnel are allowed to connect cables.
Before connecting cables, use a multimeter to measure the input voltage and
ensure that the power supply is disconnected.
All units must be reliably grounded before power-on.
Stay away from the equipment when preparing cables to prevent cable scraps
from entering the equipment. Cable scraps may cause sparks and result in
personal injury and equipment damage.
Wear insulated gloves and use insulated tools to prevent electric shocks or
short circuits.
Cables should be securely connected and free of contact with components,
such as the fan.
When laying out cables, ensure that the power cables and signal cables are
routed and bound separately.
