Page 341
TVR CONNECT 220V 60Hz 5.3.5 Bending piping Bending copper piping reduces the number of brazed joints required and can improve quality and save material. Notes for installers Piping bending methods ▪ Hand bending is suitable for thin copper piping (Ф6. 35mm - Ф12. 7mm).
Page 342
TVR CONNECT 220V 60Hz 5.5 Brazing Care must be taken to prevent oxide forming on the inside of copper piping during brazing. The presence of oxide in a refrigerant system adversely affects the operation of valves and compressors, potentially leading to low efficiency or even compressor failure.
Page 343
TVR CONNECT 220V 60Hz … box continued from previous page Piping orientation during brazing Brazing should be conducted downwards or horizontally to avoid filler leakage. Figure 3-5.6: Piping orientation during brazing Piping overlap during brazing Table 3-5.3 specifies the minimum permissible piping overlap and the range of permissible gap sizes for brazed joints on piping of different diameters.
Page 344
TVR CONNECT 220V 60Hz 5.6 Branch Joints Notes for installers ▪ Use U-shaped branch joints as specified on the Figure 3-5.8: Branch joint orientation construction drawings – do not replace U-shaped branch joints with tee joints. ▪ To avoid accumulation of oil in the outdoor units, outdoor branch joints should be installed horizontally and must not be higher than the outdoor unit refrigerant outlets.
Page 345
TVR CONNECT 220V 60Hz 5.7 Piping Connections between Outdoor Units The piping connecting the outdoor units should be horizontal and must not be higher than the refrigerant outlets. If necessary, to avoid obstacles the piping may be vertically offset below the outlets. When inserting a vertical offset to avoid an obstacle, the whole outdoor piping should be offset, rather than just the section adjacent to the obstacle.
Page 346
TVR CONNECT 220V 60Hz 5.8.2 Procedure Notes for installers Warning Only use nitrogen for flushing. Using carbon dioxide risks leaving condensation in the piping. Oxygen, air, refrigerant, flammable gases and toxic gases must not be used for flushing. Use of such gases may result in fire or explosion.
TVR CONNECT 220V 60Hz 5.9 Gastightness Test 5.9.1 Purpose To prevent faults caused by refrigerant leakage, a gastightness test should be performed before system commissioning. 5.9.2 Procedure Notes for installers Warning Only dry nitrogen should be used for gastightness testing. Oxygen, air, flammable gases and toxic gases must not be used for gastightness testing.
TVR CONNECT 220V 60Hz 5.9.3 Leak detection Notes for installers The general methods for identifying the source of a leak are as follows: 1. Audio detection: relatively large leaks are audible. 2. Touch detection: place your hand at joints to feel for escaping gas.
Page 349
TVR CONNECT 220V 60Hz 5.10.2 Procedure Notes for installers During vacuum drying, a vacuum pump is used to lower the pressure in the piping to the extent that any moisture present evaporates. At 5mmHg (755mmHg below typical atmospheric pressure) the boiling point of water is 0°C.
TVR CONNECT 220V 60Hz 6 Drain Piping 6.1 Design Considerations Drain piping design should take account of the following considerations: ▪ Indoor unit condensate drain piping needs to be of sufficient diameter to carry the volume of condensate produced at the indoor units and installed at a slope sufficient to allow drainage.

TVR CONNECT 220V 60Hz 6.6 Watertightness Test and Water Flow Test Once installation of a drainage piping system is complete, watertightness and water flow tests should be performed. Notes for installers Watertightness test ▪ Fill the piping with water and test for leakages over a 24-hour period.
Page 354
TVR CONNECT 220V 60Hz 7.1.4 Installation of piping insulation With the exception of joint insulation, insulation should be applied to piping before fixing the piping in place. Insulation at joints in refrigerant piping should be applied after the gastightness test has been completed.
TVR CONNECT 220V 60Hz 8 Charging Refrigerant 8.1 Calculating Additional Refrigerant Charge The additional refrigerant charge required depends on the lengths and diameters of the outdoor and indoor liquid pipes. Table 3-8.1 shows the additional refrigerant charge required per meter of equivalent pipe length for different diameters of pipe.
TVR CONNECT 220V 60Hz 8.2 Adding Refrigerant Notes for installers Caution ▪ Only charge refrigerant after performing a gastightness test and vacuum drying. ▪ Never charge more refrigerant than required as doing so can lead to liquid hammering. ▪ Only use refrigerant R410A - charging with an unsuitable substance may cause explosions or accidents.
TVR CONNECT 220V 60Hz 9 Electrical Wiring 9.1 General Notes for installers Caution ▪ All installation and wiring must be carried out by competent and suitably qualified, certified and accredited professionals and in accordance with all applicable legislation. ▪ Electrical systems should be grounded in accordance with all applicable legislation.
TVR CONNECT 220V 60Hz 9.2 Power Supply Wiring Power supply wiring design and installation should adhere to the following requirements: ▪ Separate power supplies should be provided for the indoor units and outdoor units. ▪ Where five or more outdoor units are installed, additional residual current protection (leakage protection) should be installed as shown in Figure 3-9.1.
▪ When a single communication line is not long enough, the joint must be crimped or soldered, and the copper wire at the joint shall not be exposed. ▪ TVR CONNECT outdoor unit compatible with different generation indoor units, the communication connection type should follow table 3-9.1.
