  • Page 30: Special Precaution For R407C

    8. SPECIAL PRECAUTIONS FOR R407C SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R407C UNIT 1) WHAT IS NEW REFRIGERANT R407C? R407C is a zeotropic refrigerant mixture which has zero ozone depletion potential and thus conformed to the Montreal Protocol regulation. It requires Polyol ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.
  • Page 31 c) Ensure that the compressor is not expose to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is about to be brazed. d) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.

  • Page 32: Installation

    9. INSTALLATION LOCATION FOR INSTALLATION OF THE CONDENSING UNITS As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulfill the following requirements : • Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air).
  • Page 33 INSTALLATION IN ZONE EXPOSED TO STRONG WIND OR HIGH SNOW FALLS (FOR HEATPUMP MODEL)
  • Page 34 MAXIMUM PIPE LENGTH AND MAXIMUM NUMBER OF BENDS When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system piping resistance to the refrigerant flow increases, thus lowering the cooling capacity, and as a result the compressor may become defective.
  • Page 35 3) AMSH INSTALLATION CLEARANCE SINGLE CONDENSING UNIT INSTALLATION Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air flow. Select the coolest possible place where intake air should not be hotter than the outside temperature (max 45 °C). All Models Minimum Distance 300 mm...

  • Page 36: Vacuuming And Charging

    FLARING TECHNIQUE (FOR FLARE CONNECTION) • Cut the pipe stages by stages, Advancing the blade of pipe cutter slowly. Extra force and a deep cut will cause more distortion of pipe and therefore extra burr. • Remove burr with the burr remover. This will avoid unevenness on the flare face which will cause gas leak. Hold the flaring end down to prevent burr from dropping inside pipe.
  • Page 37 5) After evacuation, unscrew the spindle (diagram 2B) for the gas to run to indoor unit. ADDITIONAL CHARGE (FOR FLARE CONNECTION) The refrigerant gas is charged in the outdoor unit and, if the piping length to every indoor is 5m, additional charge of the refrigerant after vacuuming is not necessary.

    10. SERVICING AND MAINTENANCE The design of the AMSD & AMST outdoor series allows servicing to be carried out readily and easy. The removal of the top, side, front and back panel make almost every part accessible. Model : Cooling – AMSD/A4MSD 1010A / 1015A / 1515A Heatpump –...
  • Page 39 MODEL : AMSD2020A MODEL : AMST101010A – 101020A Under normal circumstance, these outdoor units require a check and cleaning of air intake coil surface once quarterly. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must be regularly cleaned by qualified Air Conditioner Service Technicians to ensure sufficient heat exchange and proper operation.

  • Page 40: Operation

    11. OPERATION 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.
  • Page 41 Generally, there are two kinds of common problems, i.e. starting failure and insufficient cooling. “Starting failure” is caused by electrical defect while “insufficient cooling” is caused by improper application or defects in refrigerant circuit. DIAGNOSIS OF STARTING FAILURE Starting failure Preliminary causes :- Voltage not within +/- 10% or rated...
