Page 18: Special Precautions For R410A
Special Precautions For R410A 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. 2) COMPONENTS Mixture weight composition R32(50%) and R125(50%) - Page 19 d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can.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. Invert cylinder Dip-pipe without dip-pipe...

Page 20: Installation
Installation Installation Diagram Indoor Unit Outdoor Unit CAUTION : Before installing the unit, ensure that the power supply matches the power requirement of the air conditioner... - Page 21 1) Selection Of Location And Space (A) Indoor Unit Install the fan coil (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.(See fig. 1) Ensure that air discharge is not short circuited with air intake.
- Page 22 (B) Outdoor Unit 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 23 2) Drilling Holes And Mounting Installation Plate CAUTION: i) Please check the unit weight for each model. Always ensure that the wall is sufficiently strong to withstand the weight. If not, it is necessary to reinforce the wall with plate, beams or pillars. ii) The unit cannot be directly fixed onto the wall or the likes.
- Page 24 3) Indoor Unit Preparation • • The refrigerant piping can be routed to the unit in 5 Carefully bend the pipes to the required position to direction, by using the cut outs in the unit casing. align with the hole. For right hand and rear side draw (See fig.
- Page 25 5) Water Drainage Piping The indoor drain pipe must be downward gradient for smooth drainage. Avoid situation as shown in figure below. 6) Wiring Electrical Connection • Wiring regulation on wire diameters differ from country to country. Please refer to your LOCAL ELECTRICAL CODES for field wiring rules.
- Page 26 7) Refrigerant Piping Maximum Pipe Length And Maximum Number Of Bends Always choose the shortest path for refrigerant piping and follow the recommendations as tabulated below: Model MWMX 010FR MWMX 015FR Data Max. Length, L (m) Max. Elevation, H (m) Max.
- Page 27 4) After evacuation, unscrew the spindle (diagram B) for the gas to run to indoor unit. Additional Charge The refrigerant gas is charged in the outdoor unit and, if the piping length is less than 7.6m, additional charge of the refrigerant after vacuuming is not necessary. When the piping length is more than 7.6m, please use the table below : Additional charge per meter Model...
