2. Enter Settings > System Settings > T/H Sensor, and change the preset
humidity to a value that is 10% above the humidity of the shelter. Start the
infrared humidifier and measure its phase currents. The normal phase current
for a NetCol8000-A050 unit is 7.5 A to 9.0 A, and that for a NetCol8000-A100
unit is 12.0 A to 13.5 A.
3. Restore the preset value after the test.
Step 4 Switch on the electrical heater circuit breaker and enter Settings > System
Settings > T/H Sensor as shown in 5.4.3 Setting Temperature and Humidity
Values .
1. Increase the temperature setting to 5ºC above the equipment room
temperature on the temperature control screen, start the electric heater, and
check whether the running current of each phase is in the range of 8.0 A to
9.1 A.
2. The electrical heater shuts down properly when you set the preset
temperature to a value that is 5°C below the temperature in the shelter.
Step 5 Turn on the outdoor unit circuit breaker and check that the outdoor unit has
normal power supply. Then turn on the compressor circuit breaker.
1. Check the condensing temperature, supercooling degree, and refrigerant state
(viewing from the sight glass). Adjust the supercooling degree to 4°C to 6°C
by filling in or draining refrigerant (when the ambient temperature is high,
the supercooling degree is close to 4°C. When the ambient temperature is low,
the supercooling degree is close to 6°C). No bubble should exist in refrigerant.
NO TICE
Supplement refrigerant charging only from the low pressure needle valve. For
the position of the injection port, see 4.2.3 Procedure to Partially Charging
in Refrigerant .
2. Add the refrigerant from the low pressure needle valve (1 in Figure 4-1 ) of
the refrigerating system in small or intermittent flow. Drain the refrigerant
from the high pressure needle valve (2 in Figure 4-1 ). Remove the cylinder of
refrigerant when the refrigerant meets requirements and there is no need to
fill in refrigerant.
3. Restore the preset temperature after the test.
4. Set the disabled alarms to "Enable".
Step 6 Keep the system running for least 30 minutes and check if the unit works properly.
