ACDC12B Solar Air Conditioner Heat Pump Installation Manual Before installing or using your solar air conditioner, please print and read this manual carefully and keep it for future reference. Notice To Owner/Installer This unit is designed for easy installation by an experienced person. It is legal for a homeowner to install it, however we highly recommend using a licensed HVAC technician for installation.
Page 3: Warning
INSTALLERS, Please read the following warnings to prevent voiding warranties: W ARNING: Make sure the PV panels are wired in PARALLEL, NOT SERIES. Verify voltage is within range prior to connecting to the ODU DC breaker. WARNING: Voltage from breaker box to ODU disconnect should be 220V (measured between L1 and L2.) See page 16, figure 24.

Completely remove all burrs from the cut cross section of pipe/tube. 2. Put the end of the copper tube/pipe in a downward direction as you remove burrs in order to avoid dropping burrs into the tubing.
Page 14: Air Purging
Air purging Air and moisture in the refrigerant system have undesirable effects as indicated below: Pressure in the system rises. Operating current rises. Cooling or heating efficiency drops. Moisture in the refrigerant circuit may freeze and block capillary tubing. Water may lead to corrosion of parts in the refrigeration system.

Electrical work Electric safety regulations for the initial Installation 1. If there is are any safety issues with the power source, the technician should refuse to install the air conditioner and explain the problem to the customer. 2. Power voltage should be in the range of 90%~110% of the rated voltage. 3.
Page 18 Connecting the cable to the indoor unit NOTE: Before performing any electrical work, turn off the main power to the system. 1. The inside and outside connecting cable can be connected without removing the front grille. 2. The indoor power cord type is H05VV-F or H05V2V2-F, the outdoor power cord shall be properly sized by a qualified electrician and incorporate a disconnect.

ELECTRICAL WORK Installation of the solar photovoltaic system This is a generic guide that 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 a licensed electrician or NABCEP certified solar installer.
Page 22 When disconnecting wires from a photovoltaic module that is exposed to sunlight, an electric arc may result. 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 23 Solar modules produce electrical energy when light strikes on their front surface. The DC voltage may 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 24 Fig.33 Fig.32 When performing installation in dry conditions, please ensure the tools used a r e dry. Fig 34 Abide with the safety regulations for all other components used in the system, including wiring and cables, connectors, charge c o n t r o l l e r s , inverters, storage batteries and rechargeable batteries, etc.
Page 25 Selecting the proper racking system • 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 26 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 (3inch minimum air space between module and mounting surface).
Page 28: Electrical Installation
Electrical installation General 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 parallel can increase the output current of the solar photovoltaic system, especially for applications requiring high currents, low voltages.
Page 29 Shown below, branch connectors are used (BR2). 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 air •...
Page 31 If you want to use connectors purchased by yourself the following requirements must be complied with: • Use only connectors specially designed for solar electric systems. • Use the recommended or specified tools when installing the connectors. • Do not unplug the connectors when the power is on. •...
