PIPE CONNECTION • Fasten flare nut with a torque wrench as specified in the table(refer to 3-2.). • When fastened too tight,flare nut may eventually break and cause refrigerant leakage. • Be sure to wrap insulation around the piping.Direct contact with the bare piping may result in burns or frostbite. Indoor unit connection Connect both liquid and gas pipings to indoor unit. • Apply a thin coat of refrigeration oil(J)on the flared ends of the pipes.Do not apply refrigeration oil on screw threads.Excessive tightening torque will result in damage on the screw. • To connect,first align the center,then tighten the first 3 to 4 turns of flare nut. • Use tightening torque table above as a guideline for indoor unit side joints,and tighten using two wrenches.Excessive tightening damages the flare section. • Be sure to wrap insulation around the piping.Direct contact with the bare piping may result in burns or frostbite. Outdoor unit connection Connect pipes to stop valve pipe joint of the outdoor unit following the same procedure detailed in Indoor unit connection. • For tightening,use a torque wrench or spanner. WARNING When installing the unit,securely connect the refrigerant pipes before starting the compressor. 3-4. INSULATION AND TAPING 1)Cover piping joints with pipe cover. 2)For outdoor unit side,insulate the piping,including valves. 3)Apply piping tape(G)starting from the connection on the outdoor unit. • When piping has to be installed through a ceiling,closet or where the temperature and humidity are high,use additional field-supplied insulation to prevent condensation. 4.

EXPLANATION TO THE USER 3)Evacuate the system to 4000 microns from both service valves.System manifold gauges • Using the OPERATING INSTRUCTIONS,explain to the user how to use the air conditioner must not be used to measure vacuum.A micron gauge must be used at all times.Break (the remote controller,removing the airfilters,placing or removing the remote controllerfrom the vacuum with Nitrogen(N2)into the discharge service valve to 0 PSIG. the remote controller holder,cleaning methods,precautions for operation,etc.) 4)Evacuate the system to 1500 microns. Break the vacuum with Nitrogen(N2)into the discharge service valve to 0 PSIG. Recommend that the user read the OPERATING INSTRUCTIONS carefully. 5)Evacuate the system to 500 microns. 6)Close gauge manifold valves,stop the pump,and conduct a 30 minute rise test. 7)System should hold 500 microns for a minimum of 1 hour. 8)Fully open all stop valves on both sides of gas pipe and liquid pipe.Operating without fully opening lowers the performance and this causes trouble. 9)Refer to 1-3 and charge the prescribed amount of additional refrigerant if needed. Be sure to charge slowly with liquid refrigerant.Otherwise composition of the refrigerant in the system may be changed and affect performance of the air conditioner. 10)Remove gauge manifolds and replace service port caps and tighten. 11)Leak test 5.

REMOVING THE INDOOR UNIT Remove the bottom of the indoor unit from the installation plate. When releasing the corner part,release both left and right bottom corner part of indoor unit and pull it downward and forward as shown in the figure on the right. o� 5-3. PUMPING DOWN When relocating or disposing of the air conditioner,pump down the system following the procedure below so that refrigerant is not released into the atmosphere. 1)Connect the gauge manifold valve to the service port of the stop valve on the gas pipe side of the outdoor unit. 2)Fully close the stop valve on the liquid pipe side of the outdoor unit. 3)Close the stop valve on the gas pipe side of the outdoor unit almost completely so that it can be easily closed fully when the pressure gauge shows 0 psi[Gauge](0 Mpa). 4)Start the emergency COOL operation. To start the emergency operation in COOL mode,disconnect the power supply plug and/or turn off the breaker.After 15 seconds,connect the power supply plug and/ or turn on the breaker,and then press the E.O.SW once.(The emergency COOL operation can be performed continuously for up to 30 minutes.) 5)Fully close the stop valve on the gas pipe side of the outdoor unit when the pressure gauge shows(0.1 to 0 psi[Gauge](0.05 to 0 Mpa)). 6)Stop the emergency COOL operation. To stop operation,press the E.O.SW several times until all LED lamps turn off. Refer to operating instructions for details. tWARNING When pumping down the refrigerant,stop the compressor before discon- necting the refrigerant pipes.The compressor may burst if air etc.get into it.
