• The remaining charge is done until the installation has reached a level of stable nominal condition during operation.
• Never leave the filling cylinder connected to the circuit.
• Suction, Liquid valves and Receiver Rotolock  valves as Schrader port for service operation like Gas Charging, pressure measurement.

Verification before commissioning

| Use safety devices such as safety pressure switch and mechanical relief valve in compliance with both generally and locally applicable regulations and safety standards. Ensure that they are operational and properly set.
---|---
Check that the settings of high-pressure switches and relief valves don’t exceed the maximum service pressure of any system component.

• Verify that all electrical connections are properly fastened and in compliance with local regulations.
• When a crankcase heater is required, it must be energized at least 12 hours before initial startup and start-up after prolonged shut-down period.
• Pressure drop in the suction and liquid line pipes must be evaluated as per evaporator location and distance (refer coolselector2).

Start-up

• Never start the unit when no refrigerant is charged.
• All service valves must be in the open position. See picture 3.
• Check compliance between unit and power supply.
• Check that the crankcase heater is working.
• Check that the fan can rotate freely.
• Check that the protection sheet has been removed from the backside of condenser.
• Balance the HP/LP pressure.
• Energize the unit. It must start promptly. If the compressor does not start, check wiring conformity, voltage on terminals and sequence phase.
• Eventual reverse rotation of a 3-phase scroll compressor can be detected by following phenomena; unit is equipped with a phase-reversal relay and compressor doesn’t start, the compressor doesn’t build up pressure, it has abnormally high sound level and abnormally low power consumption. In such case, shut down the unit immediately and connect the phases to their proper terminals.
• If the rotation direction is correct the low pressure indication on the low pressure gauge shall
  show a declining pressure and the high pressure indication on the high pressure gauge shall show an increasing pressure.

Check with running unit

• Check the fan rotation direction. Air must flow from the condenser towards the fan.
• Check current draw and voltage.
• Check suction superheat to reduce risk of slugging.
• When a sight glass is provided observe the oil level at start and during operation to confirm that the oil level remains visible.
• Respect the operating limits.
• Check all tubes for abnormal vibration. Movements in excess of 1.5 mm require corrective measures such as tube brackets.
• When needed, additional refrigerant in liquid phase may be added in the low-pressure side as far away as possible from the compressor. The compressor must be operating during this process.
• Do not overcharge the system.
• Follow the local regulations for restoring the refrigerant from unit.
• Never release refrigerant to atmosphere.
• Before leaving the installation site, carry out a general installation inspection regarding cleanliness, noise and leak detection.
• Record type and amount of refrigerant charge as well as operating conditions as a reference for future inspections.

Maintenance

| Always switch off the unit at main switch before remove fan panel.
---|---
Internal pressure and surface temperature are dangerous and may cause permanent injury.

Maintenance operators and installers require appropriate skills and tools. Tubing temperature may exceed 100°C and can cause severe burns.

Ensure that periodic service inspections to ensure system reliability and as required by local regulations are performed.

To prevent system related problems, following Periodic maintenance is recommended:

• Verify that safety devices are operational and properly set.

• Ensure that the system is leak tight.

• Check the compressor current draw.

• Confirm that the system is operating in a way consistent with previous maintenance records and ambient conditions.

• Check that all electrical connections are still adequately fastened.

• Keep the unit clean and verify the absence of rust and oxidation on the unit components, tubes and electrical connections.
  The condenser must be checked at least once a year for clogging and be cleaned if deemed necessary. Access to the internal side of the condenser takes place through the fan panel. Microchannel coils tend to accumulate dirt on the surface rather than inside, which makes them easier to clean than fin-&-tube coils.

• Switch off the unit at main switch before remove any panel from the condensing unit.

• Remove surface dirt, leaves, fibres, etc. with a vacuum cleaner, equipped with a brush or other soft attachment. Alternatively, blow compressed air through the coil from the inside out, and brush with a soft bristle. Do not use a wire brush. Do not impact or scrape the coil with the vacuum tube or air nozzle.

If the refrigerant system has been opened, the  system has to be flushed with dry air or nitrogen to remove moisture and a new filter drier has to be installed. If evacuation of refrigerant has to be done, it shall be done in such a way that no refrigerant can escape to the environment.
