CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 9 Outdoor unit installation The outdoor unit must be installed on a rigid and stable base to avoid any increase in the noise level and vibration, particularly if the outdoor unit is to be installed in a location exposed to strong winds or at a height, the unit must be fixed to an appropriate support(wall or ground). Fix the outdoor unit with anchor bolts. Note The anchor bolt must be 20mm or higher from the base surface.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 10 Connecting the cable Two electronic cables must be connected to the outdoor unit. ◆ The connection cord between indoor unit and outdoor unit. ◆ The power cable between outdoor unit and auxiliary circuit breaker. ◆ Specially for Russian and European market, before installation, the supply authority should be consulted to determine the supply system impedance to ensure compliance.

CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 13 CAUTION ◆ You should connect the power cable into the power cable terminal and fasten it with a clamp. ◆ The unbalanced power must be maintained within 2% of supply rating. - If the power is unbalanced greatly, it may shorten the life of the condenser. If the unbalanced power is exceeded over 4% of supply rating, the indoor unit is protected, stopped and the error mode indicates.

CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 16 Connecting up and removing air in the circuit The air in the indoor unit and in the pipe must be purged. If air remains in the refrigeration pipes, it will affect the compressor, reduce to cooling capacity and could lead to a malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as shown at the figure.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 17 Cutting / Flaring the pipes 1 Make sure that you have the required tools available (pipe cutter, reamer, flaring tool and pipe holder). 2 If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90° angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 18 Performing leak tests Before completing the installation (insulation of the hose and piping), you must check that there are no gas leaks. B To check for gas leaks on the... Then, using a leak detector, check the... Outdoor unit Valves on sections A and B. A Connecting the drain hose to the outdoor unit When using the air conditioner in the heating mode, ice may accumulate. During de - icing, the condensed water must be drained off safely.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 19 Using stop valve To Open the Stop Valve 1 Open the cap and turn the stop valve counterclockwise by using a hexagonal wrench. 2 Turn it until the axis is stopped. Note ◆ Do not apply excessive force to the stop valve and always use special instruments. Otherwise, the stopping box can be damaged and the back sheet can leaks. ◆ If the watertight sheet leaks, turn the axis back by half, tighten the stopping box, then check the leakage again.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 20 Adding refrigerant The outdoor unit is loaded with sufficient refrigerant for the standard piping. Thus, refrigerant must be added if the piping is lengthened. This operation can only be performed by a qualified refrigeration specialist. For quantity of adding refrigerant, refer to page 21. 1 Check that the stop valve is closed entirely. 2 Charge the refrigerant through the service port of liquid stop valve.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 21 How to Calculate the Quantity of Adding Refrigerant If you have used more than 5m, add “Q” of refrigerant for extra meter. (For maximum piping length and height, refer to page 15) The quantity of additional refrigerant is variable according to the installation situation. Thus, make sure the outdoor unit situation before adding refrigerant. This operation can only be performed by a qualified refrigeration specialist.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 22 Checking correct grounding If the power distribution circuit does not have an earth or the ground does not comply with specifications, an grounding electrode must be installed. The corresponding accessories are not supplied with the air conditioner. Carbon plastic Steel core PVC-insulated green/ yellow wire 1 Select an grounding electrode that complies with the specifications given in the illustration.
CH36BTX IM_E_23807 2005.12.16 11:28 AM Page 25 Testing operations 1 Check the power supply between the outdoor unit and the auxiliary circuit breaker. Single phase power supply: L, N Three phase power supply: L1, L2, L3, N 2 Check the indoor unit. 2-1 Check that you have connected the power and communication cables correctly. (If the power cable and communication cables one mixed up or connected incorrectly, the PCB will be damaged.
