IMPORTANT! Please Read Before Starting This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently. When Transporting Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back.
PAGE 3
When Servicing CAUTION • Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring. • Keep your fingers and clothing away from any moving parts. • Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced. WARNING NOTICE • Do not clean inside the indoor and outdoor units by users. Engage authorized dealer or specialist for cleaning.

Precautions for Installation Using New Refrigerant 1. Care regarding tubing 1-1. Process tubing Material: Use C1220 phosphorous deoxidized copper specified in JIS H3300 “Copper and Copper Alloy Seamless Pipes and Tubes.” Tubing size: Be sure to use the sizes indicated in the table below. Use a tube cutter when cutting the tubing, and be sure to remove any flash. This also applies to distribution joints (optional).
PAGE 5
Configuration and characteristics of cylinders 3-2. Use R410A exclusive cylinder only. When charging with a refrigerant cylinder, use an electronic scale for charging refrigerant. In this case, if the volume of refrigerant in the cylinder becomes less than 20% of the fully-charged amount, the composition of the refrigerant starts to change. Thus, do not use the refrigerant if the amount in the charging cylinder is less than 20%.

HOW TO PROCESS TUBING Deburring The liquid tubing side is connected by a flare nut, and the gas tubing side is connected by brazing. After Before 1.
PAGE 125
1. Specifications Caution Before Connecting Tubes Tightly (1) Apply a sealing cap or water-proof tape to prevent dust or water from entering the tubes before they are used. (2) Be sure to apply refrigerant lubricant to the matching surfaces of the flare and union before connecting them together. This is effective for reducing gas leaks. (Fig. 1-113) (3) For proper connection, align the union tube and flare tube straight with each other, then screw on the flare nut lightly at first to obtain a smooth match.

1. Specifications Do not use a spanner to tighten the valve stem caps. Doing so may damage the valves. Depending on the installation conditions, applying excessive torque may cause the nuts to crack. Packed valve Charging port Valve stem Precautions for Packed Valve Operation If the packed valve is left for a long time with the valve stem cap removed, refrigerant will leak from the valve. Therefore, do not leave the valve stem cap removed. Use a torque wrench to securely tighten the valve stem cap.
PAGE 127
1. Specifications 4. Taping the Tubes (1) At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped together with armoring tape in 1 bundle. To prevent condensation from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing. Inter-unit control wiring (2) Wrap the armoring tape from the bottom of the outdoor unit to the top of the tubing where it enters the wall. As you wrap the tubing, overlap half of each previous tape turn.

1. Specifications 1-14. LEAK TEST, EVACUATION AND ADDITIONAL REFRIGERANT CHARGE Manifold gauge Perform an air-tightness test for this package A/C. Check that there is no leakage from any of the connections. Air and moisture in the refrigerant system may have undesirable effects as indicated below.
PAGE 129
1. Specifications (3) Pressurize the system up to 4.15 MPa (42 kgf/cm2G) with dry nitrogen gas and close the cylinder valve when the gauge reading reaches 4.15 MPa (42 kgf/cm2G). Then, test for leaks with liquid soap. CAUTION Manifold valve Pressure gauge Lo Hi To avoid nitrogen entering the refrigerant system in a liquid state, the top of the cylinder must be higher than the bottom when you pressurize the system. Usually, the cylinder is used in a vertical standing position.

Tubing Size, Table 1-2 Tubing Data for Models", Amount of additional refrigerant charge) using the liquid tube service valve. (Fig. 1-126) Pressure gauge Lo Hi Valve Use a balance to measure the refrigerant accurately.

2. Processes and functions 2-1 Room Temperature Control The unit adjusts room temperature by turning the outdoor unit’s compressor ON and OFF. This process is controlled by the thermostat located in the remote control unit. The figures on this and the next pages show how each part of the system performs when the room temperature changes and the thermostat activates the compressor to start (thermo ON) or stop (thermo OFF). Fig. 1 shows about the cooling cycle, and Fig. 2 shows about the heating cycle.

2. Processes and functions Overcurrent protection control (1) If the overcurrent protection circuit detects abnormal current, the compressor is stopped. (Error count = 1.) The compressor then restarts after 3 minutes. (2) If compressor start/stop is repeated 4 times (error count = 4), alarm "P26", "P29" or "H01" (count = 2 in this case only) occurs. Operation stops and does not restart.

5. Outdoor unit maintenance remote control 5-1. Overview What is the outdoor unit maintenance remote controller? Beginning with the DC-INV series of outdoor units, nonvolatile memory (EEPROM) is used in the outdoor unit PCB. In this way, the setting switches that were located on earlier PCBs have been converted to EEPROM data. This remote controller is an outdoor unit maintenance tool that is used to make and change the EEPROM settings.
