Page 32: Safety And Health
Safety and Health Important Note Only qualified specialists could carry out the installation, maintenance and commissioning of the system. 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 codes, ordinances and local by-laws. -
Page 33: Installation & Commissioning
Installation & Commissioning Unit Site Location • In order 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 34: Compressor Handling
Compressor Handling To ensure compressor reliability, the condensing unit together with the compressor must not tilt greater than an angle of 45°. Otherwise, the internal part of the compressor can offset from the housing springs and produce abnormal sound and vibration. Field Piping Important Note: Pipe sizing should only be determined by qualified personnel. -
Page 35: Indoor Unit
• Liquid lines should be sized to ensure a full supply of liquid refrigerant to the expansion device. Careful attention should be paid to sizing of liquid lines on large risers (above 6m). • Piping length less than 25m is highly recommended. An additional oil might be required if piping length exceeds 20m or with many oil traps. -
Page 36: Pipe Size Selection (For Evi Unit Only )
Pipe Size Selection (For EVI unit Only) Sizing of liquid and suction lines for EVI model will be different from standard scroll models. Piping sizes of this model need to follow the recommended correction coefficient of cooling capacity. This is vital as if the pipework selected is oversized, especially for the suction pipe, the gas velocity will be decreased at low mass flow rate / low evaporating temperature, causing oil return problems. -
Page 37: Pressure Testing
The mains electrical supply to the condensing unit must be via a suitable motor rated circuit breaker or fuse. Daikin condensing units require either a 230 volt / 1 phase / 50Hz supply or a 400 volt / 3 phase / 50Hz supply, both of which must include a Neutral and an Earth. -
Page 38: Pre Start-Up Checks
Mains cable type and sizing must be selected for the particular application and the electrical installation should confirm to the current local standards. • Cables to the condensing unit should wherever possible be routed through the cable glands supplied on the rear of the units. -
Page 39: Dual Pressure Switch
Vacuum operation: Do not operate scroll compressors in a vacuum condition, as this will cause the scrolls to overheat very quickly causing premature failure. System charge: Ensure an adequate liquid charge has been introduced to the high side of the system before starting to ensure a minimum operating pressure on the suction side of 0.5 bar is maintained, otherwise overheating of the scrolls and subsequent damage may occur. -
Page 40: Low Pressure Safety (Auto Reset)
Low pressure safety (Auto reset) The low pressure safety switch protects the compressor against deep vacuum operation, a potential cause of failure due to internal arcing and also operation outside the compressor limits. The low pressure safety cut out should never be set below the settings as shown in the following table. For systems without pump-down the LP switch signal contact shall be used to energize a low pressure safety alarm. -
Page 41: For Evi Unit Only
For EVI unit only Controller EXD-HP1 The controller EXD-HP1 used in the Series 4 EVI unit operates as an economizer control. The setting of controller is preset by the factory and is password protected. Users are not allowed to change any settings in the controller. Safety Instructions: 1. -

Page 44: 12. Trouble Shooting
5. Power Supply – Inspect at regular intervals. • Check the running current and voltage for the condensing unit. • Check the electrical wiring and tighten the wires onto the terminal blocks if necessary 6. Refrigerant Charge • Check the refrigerant charge by ensuring that the system is operating correctly, the pressures are as expected and that the liquid line sight glass shows a full bore of liquid refrigerant. -
