When the schrader port is used for this, remove the internal valve. • It is recommended to insulate the suction pipe up to the compressor inlet with 19 mm thick insulation. 5 – Leak detection Never pressurize the circuit with oxygen or dry air. This could cause fire or explosion. • Do not use dye for leak detection. • Perform a leak detection test on the complete system. • The maximum test pressure is 32 bar. • When a leak is discovered, repair the leak and repeat the leak detection. 6 – Vacuum dehydration • Never use the compressor to evacuate the system. • Connect a vacuum pump to both the LP & HP sides. • Pull down the system under a vacuum of 500 μm Hg (0.67 mbar) absolute. • Do not use a megohmmeter nor apply power to the compressor while it is under vacuum as this may cause internal damage. 7 – Electrical connections • Switch off and isolate the main power supply. • Ensure that power supply can not be switched on during installation. • All electrical components must be selected as per local standards and unit requirements. • Refer to wiring diagram for electrical connec- tions details. • Ensure that the power supply corresponds to the unit characteristics and that the power supply is stable (nominal voltage ±10% and nominal frequency ±2,5 Hz). • Dimension the power supply cables according to unit data for voltage and current. • Protect the power supply and ensure correct earthing. • Make the power supply according to local stan- dards and legal requirements. • The unit is equipped with high and low pressure switches, which directly cut the power supply to the compressor in case of activation. Version W04 is also equipped with phase sequence relay to protect the unit against phase loss/sequence/ asymmetry and under-/over-voltage. For units with a 3-phase scroll compressor, cor- rect phase sequence for compressor rotation direction shall be observed. • Determine the phase sequence by using a phase meter in order to establish the phase orders of line phases L1, L2 and L3. • Connect line phases L1, L2 and L3 to main swit- ch terminals T1, T2 and T3 respectively. 8 – Filling the system • Wear protective stuff like goggles and protec- tive gloves. • Never start the compressor under vacuum. Keep the compressor switched off. • Before charging the refrigerant, verify that the oil level is between ¼ and ¾ on the compressor oil sight glass. If additional oil is required please refer to the compressors label for type of oil. • Use only the refrigerant for which the unit is designed for. • Fill the refrigerant in liquid phase into the condenser or liquid receiver. Ensure a slow charging of the system to 4 – 5 bar for R404A / R507, R22 or R448A/R449A and approx. 2 bar for R134a. • Do not put liquid refrigerant through suction line. • It is not allowed to mix additives with the oil and/or refrigerant • The remaining charge is done until the instal- lation has reached a level of stable nominal condition during operation. • Never leave the filling cylinder connected to the circuit. 9 – Verification before commissioning Use safety devices in compliance with both generally and locally applicable regulations and safety standards. • 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 start- up and start-up after prolonged shut-down period. 10 – Start-up • Never start the unit when no refrigerant is char- ged. • 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 re- moved from the backside of condenser. • Balance the High Pressure / Low 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 com- pressor can be detected by following phe- nomena; unit 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 pres- sure indication on the low pressure gauge shall show a declining pressure and the high pres- sure indication on the high pressure gauge shall show an increasing pressure. 11 – 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 slug- ging. • 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. Move- ments 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 pro- cess. • Do not overcharge the system. • 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. 12 – 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 re- move 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 com- pressed 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 refri- gerant can escape to the environment. 13 - Warranty Always transmit the model number and serial num- ber with any claim filed regarding this product. The product warranty may be void in following cases: • Absence of nameplate. • External modifications; in particular, drilling, welding, broken feet and shock marks. • Compressor opened or returned unsealed. • Rust, water or leak detection dye inside the compressor. • Use of a refrigerant or lubricant not approved by Danfoss. • Any deviation from recommended instructions pertaining to installation, application or main- tenance. • Use in mobile applications. • Use in explosive atmospheric environment. • No model number or serial number transmit- ted with the warranty claim. 14 – Disposal Danfoss recommends that condensing units and oil should be recycled by a suitable company at its site.
