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. Care must be taken to ensure that the refrigerant lines are free of foreign matter.

Use Dry nitrogen for leak testing.

Pressurize the system to 3500 KPA/ 508 Psig and let stand for one hour. Note any pressure changes. The system must be observed over a period of one hour to ensure that no pressure drop occurs, having due regard to temperature variation throughout the system. Australian refrigerant handling code of practice 5.33

Evacuate the System

Connect the low-pressure hose from the gauge set to the Low-pressure connection on the outdoor unit.

Vacuum the system down to 500 Microns of mercury. Allow the system to stand for one hour to detect leakage. A small rise may indicate water boiling off in the system. A large rise above 600 microns may indicate leakage in the piping. Australia and New Zealand refrigerant handling code of practice 6.4.

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.
The low-pressure gauge should read approximately 150 PSI.

Before performing electrical Work, Read these cautions.

• All wiring must comply with local and national electrical codes and regulations.
• All work must be accomplished by a licensed electrician.
• All electrical connections must be made according to the Electrical Connection Diagram.
• If there is a serious safety issue with the power supply, stop work immediately. Explain your reasoning to the client and refuse to install the unit until the safety issue is properly resolved.
• Power voltage should be within 90-100% pf rated voltage. Insufficient power supply can cause malfunction, electrical shock, or fire.
• Only connect the unit to an individual branch circuit. Do not connect another appliance to that outlet.
• The units must be properly earthed.
• 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.

Before performing any electrical or wiring work, turn off the main power to the\ system.

Connect the cable from the indoor unit to the outdoor unit using the four- conductor cable. A plug is prefabricated on the Outdoor end.

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.

Connect the solar DC to the dc connections provided via a solar isolator mounted  adjacent to the out-door unit.

Installation of Solar Modules

Solar Modules must be installed in accordance with all applicable codes. Some of them are the local building codes, the Building Code of Australia, AS / NZS 4777 and AS / 5033. The must be installed by a licenced, competent person.

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.

For example, if the lowest recorded temperature is 4 to 0 degrees C and the VOC of a module is 44.2 Vdc, one would multiply 44.2 by 1.1 equalling 4.42 volts.

Adding 44.2 and 4.42 equals the low temperature VOC of 48.62.

Dividing the maximum VOC input of 380 Vdc by 48.62 yields the maximum number of solar modules 7.81. Rounding down yields 7 modules max at that low temperature

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.

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. If connected to the AC supply, the outdoor unit must be connected to the 230-volt AC distribution board via a type A or B residual current and overcurrent device

Solar Module installation

This manual contains information regarding the installation and safe handling of solar photovoltaic module(s). All instructions should be read and understood before attempting to install. If there are any questions, please contact our sales department for further explanation. The installer should conform to all safety precautions listed in this guide when installing the modules.

This manual does not describe specific structures and installation procedures.

An approved solar technician must be consulted to determine the following:

• The specifications of the solar photovoltaic system
• Cable material
• Connecting components
• Bracket and support
• Supporting parts
• Switching and circuit protection

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.

All electrical connections should be made with approved MC-4 type connectors, and from the same manufacturer. (AS / NZS 5033 clause 4.3.7 (k)

One individual solar module generates DC voltage greater than 30V when exposed to sunlight. Contact with a DC voltage of 30V or more is potentially hazardous. Do not touch the contacts of electrical terminals.

Do not touch the module contacts.

Keep children away from the system while transport and installing mechanical and electrical components.

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.

Do not work on solar modules in wet conditions

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.
• The module should be facing north in the southern latitudes for best power generation.
• An approved solar technician should be consulted to determine the best orientation of the solar panels.

Selecting the proper support frame:

• Always observe the instructions and safety precautions included with the support frame to be used with the modules.

• Never attempt to drill holes in the glass surface of the module. It will void the warranty.

• Do not drill additional mounting holes in the frame of the module. It will void the warranty.
  

• Modules must be securely attached to the mounting structure using four mounting points for normal installation. If additional wind or snow loads are considered  forthe installation additional mounting points should also be used.

• The support frame must be made of durable, corrosion resistant and UV resistant material.

• The heat expansion and cold contraction of the support frame should have no effect on its usage and performance

Ground mounting:

• Select the height of the mounting system to prevent the lowest edge of the module from being covered by snow in winter in areas the experience heavy snowfalls. In addition, assure the lowest portion of the module is placed high enough that it is not shaded by plants or trees and is free from the effects of sand and stone driven by wind.
  

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.

The roof installation of solar modules may affect the fireproofing of the house construction and it may be necessary to use an earth ground fault circuit breaker.

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. 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:

• 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.
• Both sides of an MC 4 type connection must be of the same type and manufacturer.
• Multistrand solar wire, having a minimum cross section of 2.5 sq mm or larger must be used.
• Cable installation must comply with all local and national codes and regulations.
• A switch disconnector rated for DC must be used between the array and the outdoor unit. If not adjacent to the array a separate switch must be installed at the array.
  
  

Earth Fault Protection Solar DC

Roof mounted DC PV arrays located on dwellings must be provided with DC earth fault protection per US Electrical code NEC 2005 Article 690.5. Earth fault protection isolates the Neutral conductor. (in DC this is usually the negative wire) from earth when a ground fault occurs.
