Page 11: Application Guidelines
Too low superheat during low ambient condition that can condense refrigerant inside suction line. Compressor Rotary Compressor The rotary compressor inside DAIKIN condensing unit is a high-pressure dome compressor, with 2 poles 3phase AC motor. The pressure inside the shell of compressor is a high (discharge) pressure and have high temperature. -
Page 12: Voltage Imbalance
Therefore, the above-mentioned situation should be taken into consideration. Over Pressure Protection All Daikin condensing units are fitted with adjustable auto reset low pressure switch and manual reset cartridge type high pressure switch. Low Pressure Switch The low-pressure safety switch protects the compressor against deep vacuum operation or loss of refrigerant conditions, to avoid internal arcing at the electric terminal and the damage of compressor. -
Page 13: High Pressure Switch
Application Guidelines The low-pressure safety cut out should never be set below the Table 6 settings as shown in the and THE SETTINGS MUST BE ADJUSTED TO SUIT THE APPLICATION BEFORE STARTING THE UNIT. Setting Procedure for Single Pressure Switch: Cut in range: Turning the range adjusting screw (4) clockwise will decrease the cut-in pressure setting and vice versa. -
Page 14: Suction Accumulator
Application Guidelines Figure 7: Piping Diagram for Pump Down System Suction Accumulator An accumulator is required if repeated flooded starts could occur, dilute the oil in the compressor causing inadequate lubrication and bearing wear. A suction accumulator MUST added at suction line near to compressor for: System with charge exceed compressor limit. -
Page 15: Health And Safety
Health and Safety DAIKIN Condensing Unit has to be installed and commissioned by competent personnel, who are familiar with refrigeration systems and components including all controls. To avoid potential injury, use care when working around coil surfaces or sharp edges of metal cabinets. All piping and electrical wiring should be installed in accordance with all applicable standards and local laws. -
Page 16: Installation
Installation Unit location To achieve maximum cooling capacity, the installation location for the condensing unit should be carefully selected. • Install the condensing unit in such a way so that hot air ejected by the condensing unit cannot be drawn in again (short circuit of hot discharge air). -
Page 17: Field Piping
Installation Field Piping Pipe sizing should only be determined by qualified personnel. Correct line sizing will minimize the pressure drop and maintain sufficient gas velocity for proper oil return. All applicable standards must be observed in the installation of refrigerant piping. To ensure satisfactory operation and performance, the following points should be noted: •... -
Page 18: Pressure Testing
Installation Pressure Testing The condensing units are pressure tested in the factory prior to dispatch. All units come with a holding charge of oxygen free nitrogen. Remove the holding charge indication tag which is tied to service valve before installation. Once the pipework installation is complete, it should be pressure tested for leaks prior to evacuation. -
Page 19: System Charging
Installation System Charging Once system evacuation has been completed, the system could be charged with the approved refrigerant. Refrigerant must be charged with liquid on the high-pressure side to the extent possible, with the compressor in OFF condition and service valves must be closed. The service port on the receiver outlet rotolock valve (liquid line) can be used for initial charge. -
Page 20: Electrical
A mains isolator MUST also be fitted to all condensing units unless site conditions or regulations dictate differently. Daikin condensing units require a 400 Volt / 3 Phase / 50Hz supply, both of which must include a Neutral and an Earth. Table 5... -

Page 25: Check List
Check List BEFORE START-UP No. Description Check Is the unit in good condition with holding gas and without any visible damage? Has the unit been transported in upward position? Is the crankcase oil level between 1/4 and 3/4 of the compressor sight glass (only applicable to scroll compressor)? Is the power supply on site in line with the unit specification? Is air short circuit and/or air blockage avoided? -
Page 26: During Commissioning
Check List DURING COMMISSIONING Description Check Is the suction pressure decreasing and the discharge pressure increasing? Is the compressor rotation correct (no abnormal noise and with compression)? Is the crankcase oil level between 1/4 and 3/4 of the scroll compressor sight glass? (after 3 or 4 hours of operation) Is the discharge temperature within the limits (between 50 °C and 90 °C)? Is the suction superheat within the limits (between 5K and 20K) during normal operation? - Page 27 DAIKIN REFRIGERATION MALAYSIA SDN. BHD.
