Features M5HDC-2010 Features Adequate External Static Pressure The external static pressure is specially designed to blend in most of the interior design and yet to ensure a sufficient heat transfer capability. Aluminium Slit Fin The unique slit fin on the heat exchanger greatly increases the heat transfer efficiency and thus boosts up the unit capacity. Short Piping Reduce installation cost, improved reliability efficiency compared to roof mounted units.

Application Information M5HDC-2010 Installation Guideline Safety Precautions WARNING • Installation and maintenance should be performed by qualified persons who are familiar with local code and regulation, and experienced with this type of appliance. • All field wiring must be installed in accordance with the national wiring regulation. • Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing wiring work according to the wiring diagram.
M5HDC-2010 Application Information Caution Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them. Installation of Indoor Unit For installation of indoor unit, please refer to the indoor unit technical manual. Installation of Outdoor Unit The outdoor unit has to be installed as per recommended installation clearance (Diagram A) Make sure that the location is suitable for piping and drainage. Precaution steps as below : i) Use the hanging bracket supplied with the unit.
Application Information M5HDC-2010 Wiring Wiring Electrical Connections • Wiring regulations on wire diameters differ from country to country. Please refer to your LOCAL ELECTRICAL CODES for field wiring rules. Be sure that installation comply with such rules and regulations. General Precautions • Ensure that the rated voltage of the unit corresponds to the name plate before carrying out proper wiring according to the wiring diagram. • Provide a power outlet to be used exclusively for each unit.
M5HDC-2010 Application Information Piping Connection To The Units • Align the center of the piping and sufficiently tighten the flare nut with fingers. • Finally, tighten the flare nut with torque wrench until the wrench clicks. • When tightening the flare nut with torque wrench, ensure the direction for tightening follows the arrow on the wrench. Pipe Size (mm/in) 6.35 (1/4) Torque (nm) 18 9.53 (3/8) 42 15.
Application Information M5HDC-2010 4) After evacuation, unscrew the spindle (diagram 2) for the gas to run to indoor unit. Diagram 2 • The refrigerant gas has already charged into the outdoor unit. For the piping length of 5m. Additional refrigerant charge after vacuuming is not necessary. • When the piping length is more than 5m, please use the table below (unit in gram).
M5HDC-2010 Application Information Overall Checking • Ensure the following, in particular :1) The unit is mounted solidly and rigid in position. 2) Piping and connections are leak proof after charging. 3) Proper wiring has been done. • Drainage check - pour some water into drain pan. • Test run 1) Conduct a test run after water drainage test and gas leakage test.
Application Information M5HDC-2010 Special Precautions When Dealing with Refrigerant R410A Unit (1) What is new refrigerant R410A? R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential.
M5HDC-2010 Application Information (5) Handling and installation guidelines Like R22 system, the handling and installation of R410A system are closely similar. All precautionary measures; such as ensuring no moisture, no dirt or chips in the system, clean brazing using nitrogen, and thorough leak check and vacuuming are equally important requirements. However, due to its hydroscopic POE oil, additional precautions must be taken to ensure optimum and trouble free system operation.
