Ventilation Guidelines

These guidelines are for proper heat pump operation and are not related to refrigerant storage. Ensure compliance with AS/NZS 5149 requirements.

For indoor installations, be aware of potential issues like air recirculation, which can gradually decrease air temperature, leading to reduced efficiency or failure. Ensure the ambient air temperature does not drop below 5°C and monitor it continuously.

Recommendations for Stable Air Temperature:

• For indoor installations, choose spaces with an air volume greater than 53m³.
• If the area is smaller than 53m³, ensure cross ventilation (natural or mechanical).
• Natural ventilation requires appropriately sized openings on opposite ends of the enclosure.
• Mechanical ventilation requires a minimum air volume of 1000 m³/h (278 L/s) using supply or extract fans.
• In mechanically ventilated areas, establish a make-up air pathway (e.g., grilles, undercut doors, open windows).
• Position the make-up air pathway on the opposite side of the enclosure from the fan for effective cross ventilation.

Installation of the Heat Pump

Base:

• The unit must be installed on a concrete plinth or stable structure capable of supporting over 400kg. The structure must remain stable and not shift. A concrete base of at least 50mm thick or a hardwood slat of at least 25mm thickness is required. Concrete base pavers should be a minimum of 600mm x 600mm.
• Ensure all four feet of the unit are supported by the base to avoid warranty issues.
• Ensure proper drainage for potential overflow.
• Position the unit completely vertically and level for proper condensate drainage. A tilt exceeding 3° may void the warranty.
• If there's a risk of property damage due to water leakage, install a safety tray (overflow tray).
• The unit has no service panels on the front or back faces, allowing installation flush against the wall if other clearance requirements are met.
• According to AS/NZS 60335.2.40:2023 clause 20, a fixed method is recommended.

Air Flow:

• Do not install the unit where falling debris could block air vents or damage the unit.
• Avoid locations with multiple walls or structures.
• When installing under fixtures or eaves, maintain clearances: 300mm above, 600mm at fan exhaust, and 150mm at fan intake.
• All mechanical components and operational controls must be accessible for maintenance.
• Ensure the control interface is easily accessible, with clear access to the electrical panel at the back. Improper installation may void the warranty.

Warning: A minimum of 20m³ of unobstructed space surrounding the unit is required. For indoor installations, ensure compliance with AS/NZS 5149. The electrical access point and display panel should always be accessible.

Plumbing Connections

Cold Water Supply Outlet

• Uses a G 3/4" female thread. Connect using a G 3/4" socket.
• Can also serve as a drainage point for emptying the system.

Hot Water Connection

• Uses a G 3/4" female thread. Connect using a G 3/4" socket.
• Insulate all hot water lines and connections with a minimum 13mm closed-cell insulation for thermal efficiency.
• All hot water supply components must be made of copper.

Condensate Drain

Condensation generated by evaporator coils is collected in a condensate tray at the base of the heat pump. Surplus water is channeled through the condensate drain connection elbow. Route the condensate into the nearest storm water drain using a drainage pipe. Ensure the condensate line is free of kinks and runs downward for unobstructed flow.

Pressure and Temperature Relief Valve (TPR)

• The system includes a TPR valve rated for the tank's pressure. Contact your supplier if the valve is missing.
• The valve is rated at 850kPa, 10kW, with a set temperature range of 93-99°C.
• Install the TPR valve at Point 4 as indicated.
• Insulate the TPR valve with a minimum 13mm closed-cell insulation.
• Position the TPR so the drain line points downward and the discharge point remains open to the atmosphere.
• Ensure the discharge pipe runs continuously downward and is in a frost-free environment. Do not connect it to the condensate drain pipe. Regularly operate the TPR valve to remove lime deposits and confirm it is not blocked.

Checking the TPR Valve

Perform checks every six months. Locate the TPR valve, use the lever to release some water (note: water may be hot). If water flows freely, the valve is functional. If not, it needs replacement. Contact your plumber or service team for replacement.

Tempering Valve

Emerald heat pumps generate hot water above 50°C. A Tempering Valve is mandatory per AS/NZS3500 regulations for precise hot water delivery temperature control. A high-performance or solar-rated valve is advised. A difference in hot water temperature may be noticed if a previous system lacked a tempering valve; this is normal and legally mandated.

Min-Max Filling Water Pressure

Permitted pressure: Min 200KPA - Max 650KPA.

Non-return/Isolating Valve

Install a non-return or isolation valve in the cold-water supply line to isolate the system for maintenance, draining, or replacement. Do not use a hose-set.

The Demanded Quality of Water

Poor-quality water (high scale/sand) should be filtered. Analyze water quality (PH, conductivity, Chloride, Sulphate) before operation. The acceptable water quality standard is detailed in a table. Suggest using a filter mesh of about 40 meshes.

Expansion Control Valve (ECV)

Adhere to local regulations for ECV installation (optional with most councils). Ensure the connecting pipe diameter does not exceed the safety valve's. The drain outlet should be adequately sized, remain open to the atmosphere, and have no closing function. ECV rating should not exceed 700kPa.

Pressure Limiting Valve (PLV)

The water heater has a TPR valve rated at 850kPa. Check mains water pressure before installation. If mains pressure exceeds 600kPa, install a 500kPa PLV (AS1357) for system efficiency and safety.

Checking the Anode and Replacing if Required

The anode protects the inner lining of the hot water tank. Periodically inspect and replace it if degraded.

1. Turn off power and shut off the cold water inlet valve.
2. Open a hot water tap to relieve pressure.
3. Locate and unscrew the anode.
4. Examine for degradation. Reinstall if good; replace if degraded. Failure to replace may void the water tank warranty.
5. Reopen the cold water inlet valve.
6. Open a hot water tap until hot water flows, then close it.
7. Turn on power to restart the unit.

Plumbing Connections

Cleaning the Inner Tank and Electric Heating Element

For efficient operation, perform regular maintenance:

1. Switch off power to the water heater.
2. Shut off the cold water inlet valve and open a hot water tap to release pressure.
3. Attach a flexible pipe to the drain outlet and connect it to a suitable sewage drain (must withstand 34°C). If not, open cold water inlet and hot water tap until water temperature is safe.
4. Open the drain outlet and allow the inner tank water to empty. Rinse the tank multiple times if needed.
5. Close the drain outlet.
6. Fill the inner tank with water and turn the power back on.

Filling the System

Follow these steps after proper connection:

1. Once connected, fill and pressurize the tank.
2. Open the non-return valve on the cold-water inlet and at least one hot water tap. Air will escape from the tap ("bleeding the system").
3. When water consistently flows from the tap, the system is fully bled. Close the tap.
4. Always ensure the tank is completely filled with water before connecting and activating the electricity supply.

Warning: Proper installation of valves is critical for system efficiency, longevity, and safety. Improper installation can lead to pressure fluctuations, leaks, and compromised performance.

Leak Detection and Air Tightness Experiment

When conducting leak detection and air tightness testing, never introduce oxygen, ethane, or other flammable/harmful gases into the refrigeration system. Use compressed air, fluoride, or refrigerant for these tests.

To Remove the Compressor:

1. Turn off the power supply.
2. Gradually release refrigerant from the low-pressure end, reducing exhaust speed to prevent frozen oil leakage.
3. Disconnect the compressor's air suction and exhaust pipes.
4. Disconnect the compressor's power cables.
5. Unscrew and remove the compressor fixing screws.
6. Remove the compressor.

Refrigerant Filling

Check refrigerant filling status via the liquid level data on the display screen and air suction/exhaust pressure. If refrigerant leakage occurs or components need replacement, conduct an air tightness examination first.

FAQs

What is the lifespan of an Emerald Heat Pump?

The life expectancy is 10-20 years. Emerald Energy systems are built to last. Regular cleaning helps maintain optimal operation and longevity.

What is the kWh usage of an Emerald Heat Pump?

The average kWh usage is 3-4 kWh per day (0.85 kW), compared to a standard electric hot water system's 14-18 kWh per day (3.6 kW). Usage varies based on heating demand.

How Can an Emerald Heat Pump Save Money?

Heat pumps offer energy savings of up to 80% compared to electric and gas systems. They are more energy-efficient as they use electricity primarily for the compressor and fan, rather than directly heating water with an electric element.

What is Legionella Control?

Heat pumps run a daily cleaning cycle at 8:00 AM, heating the system to 60°C to prevent Legionella bacteria growth. This occurs regardless of current settings. If the target temperature is reached before 8:00 AM, the cycle is considered complete. This optimizes energy usage and ensures cleanliness.

Environmentally Friendly

Heat pump technology excels in energy efficiency, contributing to lower greenhouse gas emissions compared to traditional heating methods. They are designed for energy efficiency and environmental sustainability, making them a good choice for reducing carbon footprints and energy costs.
