07-115 SSHP_II 5/7/07 3:59 PM Page 2 IMPORTANT! Please Read Before Starting When Installing… 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. …In a Room Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.
07-115 SSHP_II 5/7/07 3:59 PM Page 3 Check of Density Limit 2. The standards for minimum room volume are as follows. The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its density will not exceed a set limit. The refrigerant (R410A), which is used in the air conditioner, is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws imposed to protect the ozone layer.
07-115 SSHP_II 5/7/07 3:59 PM Page 4 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).
07-115 SSHP_II 5/7/07 3:59 PM Page 5 3-2. Use R410A exclusive cylinder only. Configuration and characteristics of cylinders 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 Perform Zone Registration To operate the system controller properly, zone registration is required after finishing the test run (and after setting all indoor unit addresses) using one of the following methods. (a) Zone registration using the remote controller (RCS-SH80UG) Refer to page 91. (b) Zone registration using the system controller (SHA-KC64UG) Refer to page 92.
07-115 SSHP_II 5/7/07 (a) 4:00 PM Page 91 Zone registration using the remote controller (RCS-SH80UG) (Determination of central address) In this case, after confirming which indoor unit is connected to the remote controller and that the air conditioner in the OFF state, you set the central addresses one at a time.

Connecting the Refrigerant Tubing Use of the Flaring Method Many conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts. Fig.
07-115 SSHP_II 5/7/07 4:00 PM Page 98 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. 9-4) Apply refrigerant lubricant here and here Fig.
07-115 SSHP_II 5/7/07 4:00 PM Page 99 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.
07-115 SSHP_II 5/7/07 4:00 PM Page 100 9-4. 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 Gas tube Liquid tube Armoring tape (2) Wrap the armoring tape from the bottom of the outdoor unit to the top of the tubing where it enters the wall.
07-115 SSHP_II 5/7/07 4:00 PM Page 101 10. LEAK TEST, EVACUATION AND ADDITIONAL REFRIGERANT CHARGE 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.
07-115 SSHP_II 5/7/07 4:00 PM Page 102 (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 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.
