MWM-J_(ii) Application Information Installation Guideline Safety Precautions WARNING CAUTION • 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.
Application Information MWM-J_(ii) Caution Before installing the unit, ensure that the power supply matches the power requirement of the air conditioner. Installation of Indoor Unit Service Space Install the indoor unit at a location with the following requirements • Location is suitable for wiring, piping and drainage. • No obstruction of air flow into and out of unit where cooler air can be evenly distributed. • Ensure that air discharge is not short circuited with air intake.

Application Information MWM-J_(ii) 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 installations comply with the 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.
MWM-J_(ii) Application Information Piping Works • Do not use contaminated or damaged copper tubing. Do not remove plastic, rubber plugs and brass nuts from the valves, fittings, tubings and coils until you are ready to connect suction or liquid line into valves or fittings. • If any brazing work is required, ensure that the nitrogen gas is passed through coil and joints while the brazing work is being done. This will eliminate soot formation on the inside walls of the copper tubings.
Application Information MWM-J_(ii) Vacuuming and Charging The pre-charged outdoor unit does not need any vacuuming or charging. However once it is connected, the connecting pipe line and the indoor unit need to be vacuumed before releasing the R22/R407C/R410A from the outdoor unit. 1. Open the service port core cap. 2. Connect pressure gauge to the service port. 3. Connect the line to vacuum pump. Open the charging manifold valve and turn the pump on. Vacuum to -0.1 MPa (-760mmHg) or lower.
MWM-J_(ii) Application Information Diagram shows typical charging method: (Mclecular-Sieve Type) Note : R22 - Nil R410A - Nil Caution • For R410A, avoid prolong exposure of an opened compressor, or the internal part of refrigerant piping to moist air. The POE oil in the compressor and piping can absorb moisture from air. 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.
Application Information MWM-J_(ii) 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.
MWM-J_(ii) Application Information (d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is to ensure that only the original composition of R410A is being delivered into the system. The liquid composition can be different from the vapor composition. Dip-pipe Invert cylinder without dip-pipe Liquid withdrawal (e) Normally, the R410A cylinder or can is being equipped with a dip pipe for liquid withdrawal.
