Page 4: Warning
Please pay attention to the following indications. WARNING This symbol indicates the possibility of death or serious injury. CAUTION This symbol indicates the possibility of injury or damage to property. Warning Engage a properly trained person for installation. Do not install, remove, repair, or reinstall the unit by yourself (customer) to prevent the risk of fire, electrical shock, explosion, or injury. -
Page 5: Caution
Do not allow water to run into electrical parts, it may cause fire, failure of product, or electrical shock. Always ground the product to avoid fire or electrical shock. When installing the refrigerant tubing connection, make sure not to let any substance other than the specified refrigerant go into refrigeration tube. - Page 6 the air conditioner could fall with it, causing property damage, product failure, and personal injury. Do not install the product where it will be exposed to sea wind (salt spray) directly. It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.

5.6 Electrical Installation Do not use modules of different configurations in the same system. The solar photovoltaic array consists of modules connected in parallel, no more than 3 modules can be used in parallel. Modules in Figure 56 parallel can increase the output current of the solar photovoltaic system, especially for applications... - Page 28 If you want to connect the photovoltaic modules by using the cables purchased by yourself, the following requirements must be complied: Cable installation should comply with all local regional and national regulations. In some countries, an individual circuit breaker used between the solar panel and the heat pump mini-split must be installed.
- Page 29 The manufacturer of the solar photovoltaic system can supply cables suitable for use in solar electric systems. 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.

Page 32: Grounding Principals
Caution 1. Never fail to have an individual power circuit specifically for the heat pump mini-split. As for the method of wiring, be guided by the circuit diagram posted on the inside of control cover. 2. The screws which fasten the wiring in the electrical box are liable to come loose from vibrations which the unit is subjected to during the course of transportation. - Page 33 cable. Each module should connect with the grounding cable. We recommend the closed lug when grounding. First insert the ground cable into the jack of the closed lug, then insert the stainless steel bolt (M3) into the tab of the lug, the grounding hole on the frame and finally a nut to secure the entire assembly.
