Remove the protective caps from the valves. Align flared pipe ends with the valves and hand tighten. Use a spanner to support the valve. (see illustration below) While supporting the body of the valve use a torque wrench to tighten the nuts. Repeat for the indoor unit connections. -
Page 13: Releasing The Refrigerant Into The System
Releasing the refrigerant into the system Check that the low-pressure hose is connected to the low-pressure side of the outdoor unit. Check that the system has been evacuated to 500 microns. Remove the Vacuum micron gauge to prevent damage to it. Open the low pressure and high-pressure valves by winding them out anti clockwise until seated. -

Page 15: Installation Of Solar Modules
Connect 230 Volt AC to a dedicated circuit from the Distribution board. Note the circuit breaker must provide Residual Current Device (RCD) protection per AS / NZS 3000 clause 2.6.3.2.3.3. Note Per AS / NZS 3000 clause 4.19, the indoor and outdoor unit AC power must be isolated by an isolation switch adjacent to the outdoor unit. -
Page 16: Solar Array Maximum Current
Solar Array maximum current. Paralleling of the solar array is not recommended as the maximum rated Array Short circuit current is 12 amps. Galvanic considerations outdoor unit. The outdoor unit is to be treated as a non-galvanically isolated regulator. The solar isolation switches must be rated for the full array voltage and current. - Page 17 Solar modules are large and require careful handling. Only a qualified technician should install Solar Modules. Solar arrays are current limited sources. Use appropriate protection measures when working on them. They contain hazardous DC voltages. Installation of Solar Modules should be performed only by qualified persons, who are familiar with the mechanical and electrical requirements.
- Page 18 Completely cover the module with an opaque material during installation to keep electricity from being generated. Do not touch the ends of live wires. Do not wear metallic rings, watchbands, ear, nose lip rings or other metallic devices while installing or troubleshooting photovoltaic systems Use only insulated tools that are approved for electrical installations.

Page 19: Solar Array Mechanical Installation
The module frame must be properly earthed. Removal on any one module must not interrupt the earthing of the remaining modules. Solar Array Mechanical installation Selecting an installation place: • Select a suitable place for installation of the solar modules. The modules should not be shaded during the solar window part of the day. - Page 20 • Modules must be securely attached to the mounting structure using four mounting points for normal installation. If additional wind or snow loads are considered for the installation additional mounting points should also be used. • The support frame must be made of durable, corrosion resistant and UV resistant material.

Page 21: Solar Array Wiring
Provide adequate ventilation under a module for cooling. 50 mm minimum between the module and the mounting surface. Pole mounting: When installing the modules on a pole, choose a pole and module mounting structure that will withstand anticipated winds for the area. The pole must have a solid foundation. Solar Array Wiring The array is formed of modules in series. - Page 22 General installation: • Do not use modules of different configurations in the same system. • The solar photovoltaic array consists of a maximum of 10 modules of 270 watts or 8 modules of 370 watts. • The solar array total system voltage must not exceed 380 volts DC open circuit. If installed in an area that experiences temperatures lower than 20 degrees C the Voltage open circuit will rise and a calculation must be done by a qualified technician.

Do you have a question about the DGWA2-ACDCBLW12K and is the answer not in the manual?
Questions and answers
I purchased the 24,000 BTU. I purchased solar panel separately. I can't find anywhere to connect the solar panel cables to the AC hybrid unit. Can you send me some pictures or an explanation of where to connect the red and black from the disconnect switch. Will they be MC4 connectors or bare wire? I'll help will be appreciated thank you
