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. [. . . ] Mineral oils are unsuitable for use in these units and may lead to premature system failure. 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. Displace all air with oxygen-free-nitrogen. System Purging When removing air and dehydrating refrigerant pipework, use an approved type of vacuum pump only. 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. 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. The circuit protection must be selected having due regard to the compressor starting current, such that the supply cables when sized correctly, are also protected. The cable should be selected to match the nominal load of the system, in addition to the losses associated with corrections for length, temperature, impedance, etc. Earth both the indoor and the outdoor units by attaching an Earth wire. After having made the connection to the terminal board, secure the cables with a cable clamp. [. . . ] Fix the mounting plate (supplied) to the wall, using the two screws supplied. To mount, hold the remote controller parallel to the mounting plate and slide it in fully. To remove, slide the remote controller upwards and out from the mounting plate. 20 IMPROVING SYSTEM EFFICIENCY Air Flow Direction Adjustment To improve the effects of cooling and heating, use the outlet louver appropriately for cooling and heating operations. When in cooling operation the most efficient louver position will be horizontal, and when in heating operation the optimum louver position is downwards. Increasing Heating Effect One method to increase the warming effect is to fit an additional means of re-circulating the warmed air from the upper part of the room; However if the warming effect of the air conditioner is not good owing to the installation position or the structure of the room, then reset the room temperature regulator as follows to raise the temperature of the room.
