Mitsubishi Electric Air Conditioner CITY MULTI CMY-R100VBK, CMY-R200VBK Twinning Kit Installation Manual ¡For your safety, thoroughly read the following instructions prior to installation. WT05221X02 Safety Precautions ¡Thoroughly read the following “Safety Precautions” to ensure proper installation. ¡Observe the following important safety precautions at all times. ¡Hazards that can occur from incorrect handling are classified by the symbols below: WARNING CAUTION Incorrect handling can result in death or serious injury. Incorrect handling can result in bodily injury and/or structure damage. WARNING Only a dealer or qualified technician should perform installation. Properly install all parts according to the instructions in the Installation Manual. ¡Improper installation may result in refrigerant gas leakage and equipment damage. ¡If the wrong twinning pipe or wrong size connecting pipe is used, air conditioning performance will suffer. Do not make any modifications or alterations. Consult your dealer for repair. When installing or relocating the unit, check that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit. ¡Improper installation may result in water leakage, electric shock, or fire. ¡Any presence of foreign substance or air can cause abnormal pressure rise or explosion. In the event of a refrigerant leak, thoroughly ventilate the room. After installation, check for a refrigerant leak. ¡If leaked refrigerant comes in contact with a heat source, such as a fan heater, stove, or electric grill, toxic gases will be generated. ¡If refrigerant leaks and comes in contact with an open flame, toxic gases will be generated. CAUTION Do not touch the refrigerant pipes and refrigerant circuit components with bare hands during and immediately after operation. Properly dispose of packing materials. ¡Plastic bags can pose suffocation and choking hazards: keep them out of the reach of children. Tear the plastics bags before disposing of them. ¡During or immediately after operation, certain parts of the unit such as pipes and compressor may be either very cold or hot, depending on the state of the refrigerant in the unit at the time. To reduce the risk of frostbites and burns, do not touch these parts with bare hands. ❈ See the Installation Manual that came with the outdoor unit for installation instructions. 1 1. Confirming the Package Contents The following items are included with the Twinning Kit (CMY-R100VBK, CMY-R200VBK). Verify that all items are present before starting installation. ❈ Always use the twinning pipes included in the kit when preparing the twinning kit. If the pipes field-supplied do not fit the parts in the kit, use the accessory piping parts listed below.

Selecting the Correct Size Refrigerant Pipes and Using the Twinning Kit (1) Pipe size 1 Field-supply the pipes to be connected to the kit. 2 Choose the correct size pipe using the table below. Connect the fieldsupplied pipe to the twinning kit for the sizes in the table that are marked with an asterisk (*). 3 If the pipe was cut with a pipe cutter, remove the burrs and eliminate foreign materials before connecting. ❈ On the low-pressure side, the twinning kit connects to the pipes fieldsupplied inside the outdoor unit. The distributor on the low-pressure side must be placed in the outdoor unit that has a larger capacity index of the two, regardless of the relative positions of the outdoor units or their addresses. If the distributor is placed in the outdoor unit that has a smaller capacity, refrigerant will not be properly distributed and compressor failure may result. ( If outdoor units that have the same capacity are used in combination, the distributor can be placed in either outdoor unit.)

Refer to the figure below for the installation position of the twinning pipe. (5) Slope of twinning pipes (high-pressure side only) Make sure the slope of the twinning pipes are at an angle within ±15˚ to the horizontal plane. If the slope exceeds the specified angle, the unit may be damaged. ±15˚ Twinning pipe on the high-pressure side Slope of the twinning pipe is at an angle within ±15˚ to the horizontal plane. 3 (6) The length of the straight pipe between indoor units and the twinning pipe (high-pressure pipe) Use the pipes supplied in the twinning kit, and make sure the section of the field-supplied pipe that connects to the twinning pipe has at least 500 mm [19-11/16 in] of straight section. (The section of the field-supplied pipe that connects to the twinning pipe must have at least 500 mm [19-11/16 in] of straight section.) If the straight section is less than 500 mm [19-11/16 in], it may result in equipment damage. (7) Pipe connection (high-pressure side) Make sure pipes from the twinning pipe to the outdoor unit are sloped downwards. Outdoor unit 1 100mm [4 in] or more Downward slope A B Outdoor unit 2 To BC controller To BC controller Upward slope High-pressure twinning pipe High-pressure twinning pipe Total pipe length = A + B < 5m [16-7/16 ft] To indoor unit 200mm max. · If high-pressure twinning pipe is installed above the base of the outdoor unit, it should be no more than 200mm [7-7/8 in]. 3. Pipe Connection Example Connect the pipes between outdoor units, using the figure below as a reference. 1Low-pressure twinning kit Low-pressure connecting pipe (field-supplied) High-pressure connecting pipe (field-supplied) 2High-pressure twinning pipe Main low-pressure pipe (field-supplied) Main high-pressure pipe (field-supplied) 4. Insulation Cover Installation Install the insulation cover on the twinning kit after brazing the pipes and twinning kit. Insulate all refrigerant pipes. Insulate the high-pressure and low-pressure pipes separately, and pipes located inside the unit as well as the outside. Use heat-resistant insulation material (Heat resistant : at least 120˚C [248˚F], Thickness: high-pressure = 10 mm [13/32 in], low-pressure = 20 mm [13/16 in] ). Position the edges of the insulation cover and heat-resistant insulation material so as not to leave a gap, and then wrap the exterior perimeter of the pipe joints and middle with tape (field-supplied). Heat-resistant insulation material (field-supplied) Tape (field-supplied) field-supplied pipe field-supplied pipe 2High-pressure twinning pipe field-supplied pipe To be gap free To be gap free LInsulation cover Heat-resistant insulation material (field-supplied) Insulation cover Heat-resistant insulation material (field-supplied) Overlap margin of the tape Insulation covers can shrink. Overlap the tape as shown in the left figure so that there will be no gap in between the insulation cover or field-installed insulation material. Tape (field-supplied) 5. Miscellaneous Notes Secure the field-supplied pipes with a pipe cover and a cable tie in place to keep them from coming in contact with other pipes as necessary. WT05221X02 See reverse. 4
