7. Indoor Unit Installation Installation Instructions - Indoor Unit • Take out the mounting plate at the back of the indoor unit. PRIOR TO INSTALLATION • Secure the mounting plate to the wall with the screws provided. Make sure that mounting plate is flat against Before installing the indoor unit, refer to the label on the the wall.
MOUNTING PLATE DIMENSIONS NOTE: When the gas side connective pipe is Ø 16mm (5/8in) or more, the wall hole should be 90mm (3.54in). Different models have different mounting plates. For Step 4: Prepare refrigerant piping the different customization requirements, the shape The refrigerant piping is inside an insulating sleeve of the mounting plate may be slightly different.
Step 5: Connect drain hose BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE By default, the drain hose is attached to the left-hand side REGULATIONS of unit (when you're facing the back of the unit). However, All wiring must comply with local and national it can also be attached to the right-hand side.

DO NOT INTERTWINE SIGNAL CABLE 3. Connect drain hose and refrigerant piping (refer WITH OTHER WIRES Refrigerant Piping Connection section of this manual for instructions). While bundling these items together, do not intertwine or 4. Keep pipe connection point exposed to perform the cross the signal cable with any other wiring.
8. Outdoor Unit Installation Install the unit by following local codes and regulations, SPECIAL CONSIDERATIONS FOR there may be differ slightly between different regions: EXTREME WEATHER If the unit is exposed to heavy wind: Install unit so that air outlet fan is at a 90º angle to the direction of the wind.
Base pan hole of outdoor unit Seal Admisión de aire Seal Air inlet Drain joint IN COLD CLIMATES Air outlet In cold climates, make sure that the drain hose is as vertical as possible to ensure swift water drainage. If water drains too slowly, it can freeze in the hose and flood the unit.
If you will install the unit on the ground or on a Prepare the cable for connection: concrete mounting platform, do the following: USE THE RIGHT CABLE 1. Mark the positions for four expansion bolts based on • Indoor Power Cable (if applicable): H05VV-F or dimensions chart.
9. Refrigerant Piping Connection When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter the unit. The presence of other gases or substances will lower the unit's capacity, and can cause abnormally high pressure in the refrigeration cycle.
Step 4: Connect pipes Flare nut When connecting refrigerant pipes, be careful not to use excessive torque or to deform the piping in any way. You should first connect the low-pressure pipe, then the high- pressure pipe. MINIMUM BEND RADIUS Copper pipe When bending connective refrigerant piping, the minimum bending radius is 10cm.
10. Air Evacuation Preparations and Precautions 7. Wait for 5 minutes, then check that there has been no change in system pressure. Air and foreign matter in the refrigerant circuit can cause 8. If there is a change in system pressure, refer to Gas abnormal rises in pressure, which can damage the air Leak Check section for information on how to check conditioner, reduce its efficiency, and cause injury.
Note on Adding Refrigerant Some systems require additional charging depending on pipe lengths. The standard pipe length varies according to local regulations. The standard pipe length is 5m (16'). The refrigerant should be charged from the service port on the outdoor unit's low pressure valve. The additional refrigerant to be charged can be calculated using the following formula: ADDITIONAL REFRIGERANT PER PIPE LENGTH Connective Pipe...
