Page 3 SAFETY PRECAUTIONS • Read the follow SAFETY PRECAUTIONS carefully before installation. • Installation must be performed in accordance with the requirement of NEC and CEC by authorized per- sonnel only. • Incorrect installation due to ignoring of the instruction will cause harm or damage. The seriousness is classified by the following indications.
Page 4: Installation Instructions
INSTALLATION INSTRUCTIONS Selecting installation place Select an installation location which is rigid and strong enough to support or hold the unit, and select a location for easy maintenance. Read completely, then follow step by step. Indoor Unit • Do not expose the indoor unit to heat or steam. •...

Page 6: Indoor Unit Installation
INSTALLATION INSTRUCTIONS Indoor unit installation The wall for installation of the indoor unit shall be hard and firm, so as to prevent vibration. 2. Use the “+” type screw to fasten the peg board, horizontally mount the peg board on the wall, and ensure the lateral horizontal and longitudinal vertical.
Page 7 INSTALLATION INSTRUCTIONS 3. Connective Pipe and Drainage Installation 1. Run the drain hose sloping downward. Do not install the drain hose as illustrated in Fig .7. 2. When connecting extension drain hose, insulate the connecting part of extension drain hose with a shield pipe, do not let the drain hose slack.
Page 8: Outdoor Unit Installation
INSTALLATION INSTRUCTIONS 5. Piping and wrapping Bundle the tubing, connecting cable, and drain hose with tape securely, evenly as shown in Fig.12 • Because the condensed water from rear of the indoor unit is gathered in ponding box and is piped out of room.

ELECTRICAL WORK C: Putting nut on Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal.(not possible to put them on after flaring work) D: Flaring work Firmly hold copper pipe in a die in the dimension shown in the table below.
Page 11 ELECTRICAL WORK Suggest Minimum Wire Size (AWG: American Wire Gage ): Appliance Amps AWG Wire Size NOTE: • The wire size of power supply cord and intercon- nected wire and the current of the fuse or switch are determined by the maximum current indicat- ed on the nameplate which located on the side panel of the unit.
Page 12 ELECTRICAL WORK Connect the cable to the outdoor unit Remove the cover control from the unit by loos- ening the screws. See Fig.23. 2. Dismount caps on the conduit pane 3. Temporarily mount the conduit tubes(not includ- ed)on the conduit panel. 4.
Page 13: Installation Of The Solar Photovoltaic System
ELECTRICAL WORK Installation of the solar photovoltaic system • This guide contains information regarding the installation and safe handling of solar photovoltaic module. All instructions should be read and understood before attempting to install. If there is any question, please contact our sales department for further explanation. The installer should conform to all the safety precautions listed in this guide when installing the module.
Page 14 ELECTRICAL WORK • When disconnecting wires from a photovoltaic module that is exposed to sunlight, an electric arc may re- sult. Such arcs may cause burns, combustion and may otherwise create problems. Therefore, be extremely careful! • Photovoltaic solar modules convert light energy to direct-current electrical energy. They are designed for outdoor use.
Page 15 ELECTRICAL WORK • Solar modules produce electrical energy when light strikes on their front surface. The DC voltage will exceed 30V. If modules are connected in series, the total voltage is equal to the sum of the individual module voltages. If modules are connected in parallel, the total current is equal to the sum of individual module currents.
Page 16 ELECTRICAL WORK • When performing installation in dry conditions, please ensure the tools used in the dry. • Abide with the safety regulations for all other components used in the system, including wiring and ca- bles, connectors, charging regulators, inverters, storage batteries and rechargeable batteries, etc. •...
Page 17 ELECTRICAL WORK 2. Selecting the proper support frame • Always observe the instructions and safety precautions included with the support frame to be used with the module. • Never attempt to drill holes in the glass surface of the module, it will void the warranty. •...
Page 18 ELECTRICAL WORK 4. Roof mount • When installing a module on a roof or building, ensure that it is securely fastened and cannot fall as a result of wind or snow loads. • Provide adequate ventilation under a module for cooling (5cm minimum air space between module and mounting surface).
Page 19 ELECTRICAL WORK 6. General installation • Module mounting must use the pre-drilled mounting holes in the frame. • The most common mounting is achieved by mounting the module using the four symmetry points closed to the inner side on the module frame. •...
Page 20 ELECTRICAL WORK Electrical Installation 1.General installation • Do not use modules of different configurations in the same system. • The solar photovolatic array consists of modules connected in series, no more than 10 pcs 260W mod- ules can be used in series. Modules in series can increase the output voltage of the solar PV system, es- pecially for applications requiring high volatge, low currents.
Page 21 ELECTRICAL WORK • The PV-wire should be single-pole, double insulated solar cable, the length of which is due to the dis- tance from PV-modules to outdoor unit of AC, the recommended conductor cross section is AWG12, and it should accord with UL4703. •...
Page 22 ELECTRICAL WORK • Do not place the cable on the sharp edge of the things. • Attention to the minimum bending radius of the wire. • Do not unplug the connector when the power is on. • The protecting sheath must be used on the cable if there is a possible for the animals or childrens easy to touch it.
Page 23 ELECTRICAL WORK If you want to use the connector purchased by yourself, the following requirements must be complied: • Use only connector special designed for solar electric systems. • Use the recommended or specified tools when install the connectors. Do not unplug the connectors when the power is on.
Page 24: Panel Grounding
Panel Grounding GROUNDING PRINCIPALS Equipment grounding provides protection from shock caused by a ground fault and is re- quired for all PV systems by the NEC. A ground fault occurs when a current-carrying con- ductor comes into contact with the frame or chassis of an appliance or an electrical box. A person who touches the frame or chassis of the faulty appliance will complete the circuit and receive a shock.
Page 25 Panel Grounding 4 pcs solar panels grounding Using min. 4 sqmm solar cable between solar panels and air conditioner. A 25A DC circuit breaker between solar panel and air conditioner is reco- mmended. Both solar panel and air conditioner side should do a good grounding. Compatible MC4 solar connectors are used in both side of the solar cable, Please fol- low the positive and negative mark on the air conditioner.

Page 27: Air Purging
AIR PURGING CAUTION After complying to the above conditions, prepare the wiring as follows: Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wir- ing, be guided by the circuit diagram posted on the inside of control cover. The screw which fasten the wiring in the electrical fitting case are liable to come loose from vibrations which the u nit is subjected during the couse of transportation.
Page 28: Test Running Test Running
TEST RUNNING Safety and leakage check Electrical safety check Perform the electric safe check after completing installation: Grounding work After finishing grounding work, measure the grounding resistance by visual detection and grounding resistance tester. Make sure the grounding resistance is less than 4 Q 2.
