Safety Warnings • Use Copper Wires only for Power Supply • Risk of electric shock can cause injury or death. Disconnect all electric power supplies before servicing or installation • Do not use excessive torque on flare nuts during connection of the refrigeration tubes, or service valve on discharge line may be damaged. • Do not install indoor unit in damp or wet locations.
Selecting of Installation Locations Indoor Unit: • Intake and outlet should not be obstructed. • The wall the unit is to be mounted on should allow for a clear hole for the condensation drain and the refrigeration lines. • The wall the unit is mounted on should be strong enough to bear the weight and vibration of the unit. • Allow for proper clearances around the unit - see installation dimension diagram (page 5 and page 6). • Location should allow easy access for maintenance and removal of air filter.
Indoor Unit Installation Install the Rear Panel (mounting plate) Always mount rear panel horizontally. Hold the rear panel on the wall where you want the unit to be located and ensure that it is level using a plumb line or level. Once leveled, mark the screw locations on the wall. Fasten the rear panel to the wall at the location marked using the screws supplied with the unit.
Indoor Unit Installation (Cont) Terminal Board Diagram NOTE: Power Connection cable is provided in the installation kit (sold separately). If the cable is not of sufficient length, it will be necessary to purchase cable for this purpose. Do not splice cable.
Indoor Unit Installation (Cont) Prepare refrigeration Lines • Refrigeration Lines and wiring can be routed from the indoor unit several different ways using the cut-out access pieces on the back of the unit. • Bend the refrigeration lines carefully to the position needed to align with the drilled piping hole.
Outdoor unit Installation Connect Refrigeration Lines to Bundled Lines from Indoor Unit • Use standard A/C practices to attach the connection pipes to the proper pipes of the bundled lines coming through the wall from the indoor unit. • Tighten the flare nut of the connection pipes using a spanner and torque wrench. (see diagram) • Note: Do not over-tighten flare nuts, or the connection may be damaged.
Outdoor Unit Installation (Cont) Position Outdoor unit • • • Review page 5 for assistance in selecting location for outdoor unit. Make sure unit is positioned solidly and level on its foundation. Use leveling feet if necessary. If possible affix unit to foundation using proper hardware. Connect refrigeration lines to Outdoor Unit • • • • Remove caps on outdoor unit Use standard A/C practices to attach the refrigeration lines bundled in step 2 to the outdoor unit.
Testing Notes • • Installation MUST be complete prior to testing. System MUST be tested prior to operation. Leakage Test • Use standard A/C practices to properly check refrigeration tubes and connections for any leaks prior to system start up. Air Purging and Pressure Test • • • • • • • Remove bonnet (cover) of gas valve on outdoor unit. Charge system with Nitrogen to 100 PSI and check for leaks. Evacuate Nitrogen. Connect the gas valves of a vacuum gauge, vacuum pump, and outdoor unit (see diagram).
Testing (Cont) Test operation Before test operation • Do not switch on power before installation is complete. • Verify that all electrical connections are connected properly. • Verify that valves of the line set have been opened. • Remove all construction materials such as boxes, packaging, etc from operating area of the units. AUTO TEST RUN STO P Manual operation (18,000 BTU) units only H a n d lin g sw itch • Turn on power.
Testing (Cont) IF UNIT FAILS TO OPERATE PROPERLY ISSUE Unit will not operate Compressor will not operate The unit vibrates during operation Inefficient Cooling (heating) Appearance of water or condensation. CHECK Verify that Red "Power" light is illuminated. Verify that line voltage is present between terminals 1 and 3 of indoor unit. Turn unit on with remote. (you should hear a "Beep" from indoor unit). Allow 3-4 min. for unit to restart. Turn unit to "Test" mode.
