Wear antifreeze gloves when performing refrigerant related operations.
The following are the tools used for commissioning and refrigerant charging:
● Charging tools: pressure gauge (measuring range ≥ 4.0 MPa), leather hose
(withstanding a pressure of at least 4.5 MPa), vacuum pump
● Measurement tool: electronic balance
● Protective tools: insulation gloves, antifreze gloves, and insulation shoes.
● Other tools: ashlight
Table 4-5 lists the mapping between the saturation pressure and the temperature.
● Remove the refrigerant cylinder after ensuring that no refrigerant is required.
● Users include admin (preset password: Changeme) and operator (preset
password: Changeme). To enter the diagnostic mode, log in as user admin.
● If a smart cooling product is not congured with a heater or humidier, skip
the commissioning steps related to the electric heater and wet
lm humidier.
● The heater and humidier do not work at the same time.

● 1 in NetCol5000-A1 is variable and subject to changes with the smart cooling product
connection sequence. The displayed value prevails.
● If no manual operation is performed within 25 seconds after you click On, the device
will automatically run following the preset logic, and the compressor and indoor and
outdoor fans will also run according to the environment.
Step 2 Click Controls > Control Information, set Startup/Shutdown to ON, and click

Step 3 Choose Controls > Control Information, set Diagnostic mode to Enter, and click
Submit.
Step 4 Choose Running Parameters > Diagnostic Mode Parameters, set Elec heater
manual control to ON, and click Submit.
1. Check that the indoor fans run properly and no alarm is generated.
2. If hot air blows out from the air exhaust vent of the fan after a period of
time, the electric heater runs properly. Set Elec heater manual control to
