01_EN_3PN05597-5R.fm Page 3 Wednesday, September 14, 2005 8:35 PM CAUTION • While following the instructions in this installation manual, install drain piping in order to ensure proper drainage and insulate piping in order to prevent condensation. Improper drain piping may result in water leakage and property damage. • Be very careful about product transportation. • Do not touch the refrigerant pipes during and immediately after operation.
01_EN_3PN05597-5R.fm Page 4 Wednesday, September 14, 2005 8:35 PM 2-4 Accessories Confirm that the following accessories are supplied. Clamp Insulation tube Others • Installation manual (1 pc.) (3 pcs.) 2-5 Main components For main components and function of the main components, refer to the Engineering Data Book. 3. BEFORE INSTALLATION • The indoor/outdoor piping length and wiring length are within the allowable range.
01_EN_3PN05597-5R.fm Page 5 Wednesday, September 14, 2005 8:35 PM • When an obstruction is present also on the air inlet side and both sides • Do not install unit in an area where flammable materials are present due to risk of explosion resulting in serious injury or death. • Refrigerant is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion , especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
01_EN_3PN05597-5R.fm Page 6 Wednesday, September 14, 2005 8:35 PM (2)When two or more outdoor units are installed side by side ss or le • Close the area under the frame so that the outlet air does not bypass there.
01_EN_3PN05597-5R.fm Page 7 Wednesday, September 14, 2005 8:35 PM • When an obstruction is present also in the upward area (1)When one outdoor unit is installed individually ss 1. Only two outdoor units can be stacked. 2. About 4 in. is required as the drain piping size for the upper outdoor unit. 3. Close the area Z (gap between the upper outdoor unit and the lower outdoor unit) so that the outlet air does not bypass there.
01_EN_3PN05597-5R.fm Page 8 Wednesday, September 14, 2005 8:35 PM 5. CAUTIONS ON INSTALLATION 6. • Before installation, confirm the strength and levelness of the foundation so that vibrations and noise are not generated. • Fix the outdoor unit securely on a rigid base with foundation bolts as shown in the foundation drawing below. (Prepare 4 sets of commercially available M12-type or equivalent foundation bolts, nuts and washers.
01_EN_3PN05597-5R.fm Page 9 Wednesday, September 14, 2005 8:35 PM 6-4 Refrigerant piping work procedure NOTE • When brazing with blowing nitrogen, set the nitrogen pressure to 2.9 psi or less by using a pressure reducing valve. Refrigerant piping Location to be brazed The field piping can be connected in four directions.
01_EN_3PN05597-5R.fm Page 10 Wednesday, September 14, 2005 8:35 PM [Measures to prevent invasion of small creatures and litter] • Block all gaps in the piping penetration areas with putty or heat insulating material (arranged in the local field) as shown in the figure below. (If small creatures, such as insects, or litter, enters the outdoor unit, a short-circuit may be caused inside the electric parts box.
01_EN_3PN05597-5R.fm Page 11 Wednesday, September 14, 2005 8:35 PM See the “Service Precautions” label on the back of the front panel for the settings for operation after replenishing refrigerant. 1. Open the gas line stop valve (leaving the liquid line stop valve, valve A in the diagram above, close) and perform the operation to add the refrigerant. 2. Once the appropriate amount of refrigerant is in, press the confirmation button (BS3) on the outdoor unit PC board (A1P), and stop operation. 3.
01_EN_3PN05597-5R.fm Page 12 Wednesday, September 14, 2005 8:35 PM • The outdoor unit has an inverter which generates noise and charges the outer casing with the leakage current. The outdoor unit should be grounded so that the effect of the generated noise on other equipment can be reduced, and that the outer casing can be discharged.
01_EN_3PN05597-5R.fm Page 13 Wednesday, September 14, 2005 8:35 PM 7-4 Transmission wiring connection procedure When using shield wire • If an excessive force is applied while connecting a cable to the terminal block on the PC board, the PC board may be damaged. Cable clamp (Copper foil is provided.) A1P Screw Shield A A B C F1 F2 F1 F2 Fix the shield area of the unit- B C C/H SELECTOR F1 F2 F1 F2 TO IN/D UNIT TO OUT/D UNIT to-unit wiring to the copper foil area of the clamp.
01_EN_3PN05597-5R.fm Page 14 Wednesday, September 14, 2005 8:35 PM 8. CHECKS AFTER COMPLETION OF WORK • Make sure to close the outer panel before leaving the outdoor unit in the power ON status. • To avoid injury, always make sure that the circuit breaker on the power supply panel of the installation is switched off before doing any work. Cautions before turning on the power • Put the insulating cover securely onto the electric parts box.
01_EN_3PN05597-5R.fm Page 15 Wednesday, September 14, 2005 8:35 PM • If the air conditioner is started within about 12 minutes after the power of the indoor/outdoor unit is turned on, the H2P indicator lights and the compressor does not run. Confirm that the LED status is as shown in the table in (2) in “9-1 Power on and check operation” before starting the air conditioner.
01_EN_3PN05597-5R.fm Page 16 Wednesday, September 14, 2005 8:35 PM When nothing is displayed in the remote controller • There might be a problem with the connection or transmission between the indoor unit and the remote controller. Check connections, and check for wire breakage. CAUTION NOTE • Where a single refrigerant facility is divided into 2 entirely independent refrigerant systems then use the amount of refrigerant with which each separate system is charged. 3 2.
