This equipment should only be installed by suitably trained operatives. In all cases ensure safe working practice: Observe precautions for persons in the vicinity of the works. Ensure that all local, national and international regulations are satisfied. [. . . ] Never use equipment which has been used with R22. R407C should only be charged from the service cylinder in the liquid phase. It is advisable to use a gauge manifold set equipped with a liquid sight glass fitted in the centre (entry) port. Material and Sizes Materials and pipes required for connection between the indoor and outdoor units. Piping material: Seamless, deoxidised copper piping for air conditioning (refrigeration quality tube). Model RAVPiping size 134/164AH 12. 7 mm (1/2") 6. 4 mm (1/4") 264AH/AH8 15. 9 mm (5/8") 9. 5 mm (3/8") Gas side Liquid side Permissible Piping Length and Head Model (RAV-) 134AH 164AH 264AH/AH8 The maximum piping length from the outdoor unit to the indoor unit 30 m The maximum height difference from the outdoor unit to the indoor unit When the outdoor unit is above When the outdoor unit is below 30 m 15 m Limit the total number of bends in the pipework to 10 or less. Pipework Installation When installing the pipework it is essential that the following points are adhered to: (i) (ii) (iii) (iv) Cleanliness is essential keep the pipework securely sealed at all times during the installation. No sight glass should be fitted to the liquid pipe. Do not incorporate an oil trap in vertical pipework. Displace all air with oxygen-free-nitrogen. System Purging When removing air and dehydrating refrigerant pipework, use an approved type of vacuum pump only. Do NOT use the factory charge to purge the air. Ensure a vacuum is drawn at -76 cmHg (-1. 013 x 105 Pa) at both the liquid and gas sides. 12 REFRIGERANT PIPING Additional Refrigerant The amount of refrigerant put into the outdoor unit at the factory is sufficient to fill up to 20 m of refrigerant pipework. If the length of the refrigerant pipework is 20 m or less, addition of refrigerant at the installation site is unnecessary. If the length of the pipework exceeds 20 m, extra refrigerant must be added. Refer to the table below for details of the extra amounts. Overcharge or undercharge of refrigerant in the outdoor unit will cause malfunction of the compressor. The prescribed amount of the replenishment of the refrigerant is shown in the table below: MODEL (RAV-) Additional amount of refrigerant to add at installation site (kg) 50 g Less than 20 m 134AH-PE 164AH-PE 264AH/AH8-PE Filled at factory Less than 25 m 0. 18 0. 18 0. 18 Less than 30 m 0. 35 0. 35 0. 35 Recharge amount if unit is reclaimed (kg) 50 g Less than 5m 0. 79 0. 94 1. 64 Less than 20 m 1. 05 1. 2 1. 9 Less than 25 m 1. 23 1. 38 2. 08 Less than 30 m 1. 4 1. 55 2. 25 * ADD ONLY R407C REFRIGERANT TO THESE UNITS * Heat Insulation Provide heat insulation on the refrigerant piping on both the liquid side and gas side separately, and ensure that all joints in the insulation are vapour sealed. Since the temperature of the piping on the gas side increases during heating operations, the heat insulating material used must be able to withstand temperatures of more than 120C. Use the pipe insulation supplied in the accessory pack to insulate the piping connecting section on the indoor unit side. Pressure Measurement Connect the pressure gauge to the locations in the table below when measuring the pressure during operation. A gauge is required since check joints are used for the connecting sections. High-pressure side Check joint in the outdoor unit Gas side packed valve Low-pressure side Gas side packed valve Check joint in outdoor unit During cooling During heating Note: During cooling operation, the pressure in the packed valve on the liquid side reduces. 13 ELECTRICAL WIRING Precautions This guide should be read and utilised in conjunction with the official published regulations and codes of practice, be they local, national or international. Each air conditioning system will have its own discrete power supply, with overload current protection. Install a multi-pole isolation switch (with 3 mm separation) in the power supply circuit. The current protective device will prevent and protect the supply cable against overcurrent. [. . . ] Both indoor units must be in the same room. Both indoor units must be of identical types, for example, both 2-Way Cassettes. The units listed below may be twinned: HEAT PUMP TWIN SET P Nominal System (HP) 2 3 4 5 Indoor Unit Models (HP) RAV-105KH-E (1) RAV-135KH-E (1. 5) RAV-165KH-E (2) RAV-265KH-E (3) Outdoor Unit Models (HP) RAV-164AH-PE RAV-264AH-PE RAV-264AH8-PE RAV-364AH8-PE RAV-464AH8-PE 21 HEAT PUMP TWIN SET-UP Wiring Connect the outdoor and the indoor unit in the following sequence: (1) Connect together the terminals 1, 2 and 3 on both the outdoor unit and indoor unit No. 1ensuring that the terminals are matched up correctly. (2) Connect together terminals 1 and 2 on indoor units No. 1 and No. [. . . ]
