System Start-Up - Carrier 50CJ Serie Installations-, Betriebs- Und Wartungsanleitung

8 - SYSTEM START-UP

All operations on the refrigerant circuit must be carried out in accordance with the applicable environmental
regulations.
After making the necessary electrical and hydraulic connections, carry out the system start-up and check the following steps:
- Check the tightness of the electrical connections,
- Check the hydraulic connections (direction of inlet/outlet connections),
- Make sure the inside of the cabinet is clean and free of foreign bodies,
- Check the electrical supply voltage and the ratings of the overload protections against the current ratings of each component,
- Check the height of the trap,
- Vent the air out of the coils via the bleed screws,
- Check the circuits for any leaks; retighten the valve if necessary,
- To configure the setpoints, refer to the "CCU Controller" manual
- The air flow rate can be adjusted manually using the inverter
- If a master/slave control system is used, make sure that the connection cable between the vertical units is in place.
- Evacuate the system to obtain -0.1 M Pa (-760 mm Hg),
- Fill with the required quantity of refrigerant fluid (for charges see the "Refrigerating circuit" section),
- Simulate a trip of the electrical components, controlled instruments and alarms.
- Check the current of each.
■ Standard components:
- Temperature alarm,
- Air flow alarm,
- Condensation unit,
- Fan motor assembly
■ Optional components:
- Temperature low limit alarm,
- Outer contact servo control,
- Electric heater,
- Humidifier
- Hot water valve
- Check the cleanliness of the humidifier supply water (option),
- After allowing the unit to run for a few hours, check the fouling level of the filter, especially in the case of an F7/ePM1 60% filter.
