Page 13: Pressure Testing The System
Pressure Testing the System Fluorocarbons refrigerant must not be put into a system for the purposes of pressure leak testing. Australian refrigerant handling code of practice 5.29 High pressure nitrogen gas bottle handling. Wear appropriate PPE including eye, ear, protection, leather gloves. Precautions: Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure and could cause damage to the air conditioner. -
Page 14: 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
• All wiring must be properly connected. Loose wiring can cause failures and result in product malfunction and possible fire. • Ensure that wires are not resting against refrigerant tubing, the compressor, or any moving parts within the unit. • If the unit has an auxiliary electric heater, it must be installed at least one meter away from any combustible materials. -
Page 16: Solar Array Maximum Voltage
Solar Array Maximum Voltage. The maximum Voltage Open Circuit (VOC) must be calculated to account for low temperature voltage rise. Failure to do may damage the equipment and void warranty. For guidance see AS / NZS 5033 4.2 PV array maximum voltage. The maximum Voltage Open Circuit for this equipment is 380 Vdc. -
Page 17: Solar Arrays In Parallel
Solar Arrays in Parallel If it is desired to use smaller solar panels in parallel arrays the maximum number of arrays is 2. Additional paralleled arrays may not improve, performance, and may cause the arrays or the air conditioner to be damaged. Solar Array maximum current. - 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.

Page 19: Solar Array Mechanical Installation
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. • The module should be facing north in the southern latitudes for best power generation. - Page 20 Roof Mounting: When installing the modules on a roof ensure that they are securely fastened and cannot fall because of wind or snow loads. When installing on a roof, ensure that the roof construction is suitable. In addition, any roof penetration required to mount the module must be properly sealed to prevent leaks.
- Page 21 Solar Array Wiring The array is formed of modules in series. The switch disconnectors must be approved for disconnecting solar DC under load. The MC 4 connectors must be approved and from the same manufacturer at each join. Mismatching connectors can cause failure and possible fire. General installation: •...
