Precautions on Installation • Check the strength and level of the installation surface so that the unit does not cause any operating vibrations or noise after installation. • Fix the unit in place securely using foundation bolts, as in the figure. (Prepare 4 sets of 5/16 inch (M8) or 3/8 inch (M10) foundation bolts, nuts and washers;...
Installation Space Requirements • Position the unit on a horizontal surface. Any tilt in the unit should be 3° or less to the horizontal. • Where a wall or other obstacle is in the path of the outdoor unit’s intake or exhaust airflow, follow the installation space requirements below.
Flaring the pipe end WARNING • Do not apply mineral oil to the flare. • Prevent mineral oil from getting into the system as this would reduce the service life of the units. • Never use piping which has been used for previous installations. Only use parts which are delivered with this unit. •...
Outdoor Unit Installation Cautions on pipe handling Wall Be sure to • Protect the open end of the pipe from dust and moisture. place a cap. • All pipe bends should be as gentle as possible. Use a pipe bender for bending. Rain If no flare cap is available, cover...

• When piping work is complete, it is necessary to perform a pressure test Compound Pressure High-pressure pressure gauge meter valve and evacuate system with a vacuum pump. • If using additional refrigerant, purge the air from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant.
Wiring WARNING • Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete grounding can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding to gas pipes could cause a gas leak and potential explosion causing severe injury or death. •...
[Method of mounting conduit] • A protection plate is fixed for protection from the high-voltage section. 1) Dismount the stop valve cover by removing the screw. 2) Dismount the protection plate by removing the 3 screws. 3) Dismount the conduit mounting cover by removing the 3 screws. 4) Pass wires through the conduit and secure them with a lock nut.
Facility Setting (cooling at low outdoor temperature) This function is designed for facilities such as equipment or computer rooms. It is never to be used in a residence or office where people occupy the space. Cutting jumper 4 (J4) on the circuit board will extend the operation range to 14°F Hook Electrical wiring box cover (3 places)
Pump Down Operation Hexagonal wrench In order to protect the environment, be sure to pump down when Liquid stop valve Close relocating or disposing of the unit. 1) Remove the valve caps from the liquid stop valve and gas stop valve. 2) Begin forced cooling operation.
