Functioning Principles of Heat Pump Water Heaters

Air source heat pump water heaters mainly consist of a compressor, an expansion valve, a filter, an evaporator, a condenser, and a fan. Powered by electricity, the compressor absorbs low-temperature and low-pressure refrigerant gas from the evaporator. It compresses the gas into high-temperature and high-pressure gas, which is passed through the condenser to transfer heat to the water. The condensed refrigerant is then throttled and depressurized by the expansion valve. It then absorbs heat from the surrounding air via the evaporator.

Technical Specifications

* The COP was measured under test conditions with an ambient air temperature of 20°C/15°C (Dry Bulb/Wet Bulb) and heating of the water from 15°C to 55°C during water heater operation.

* The noise level was measured at 1 m from the water heater during a Noise Test conducted to Standard GB/T 23137 in a hemi-anechoic chamber within a laboratory.

Installation Instructions

Transporting the Appliance

1. During transport or storage, the heat pump water heater should remain in undamaged packaging to prevent damage to the appliance. ℹ️
2. During long periods of transport or storage, the heat pump water heater must be in an upright position. ℹ️
3. For short distance transportation (under one hour), this product may be laid down within 1 hour as per indication on packaging. If laid down, the appliance must be in an upright position for 4 hours prior to its initial startup. ℹ️

Selection of Installation Site

1. Ensure the install location is stable and level, and that air can flow in and out freely, and will be minimally affected by wind. ℹ️
2. The base or surface can support the filled weight of the appliance and the condensate water can be drained freely. ℹ️
3. If installed on a base, ensure that this base is level to allow correct drainage via the condensate drain at the rear of the appliance. ℹ️
4. The location or position of the appliance will not create nuisance noise for the homeowners or neighbors, especially through proximity to bedrooms. ℹ️
5. Ensure that the location allows condensate and PTR valves to be drained into an area that will not cause damage to the surrounding area. ℹ️
6. There is sufficient space left for installation and maintenance of the appliance. ℹ️
7. There is no strong electromagnetic interference around the appliance that may affect its control functions. ℹ️
8. There are no corrosive vapours such as aerosol sprays, stain removers or household chemicals near the install location. These vapours may corrode the appliance and its fittings. ⚠️
9. Considerations have been made to prevent water pipes from freezing in colder regions. ℹ️

Plumbing Installation

WARNING -- FOR CONTINUED SAFETY OF THIS APPLIANCE IT MUST BE INSTALLED, OPERATED AND MAINTAINED IN ACCORDANCE WITH THE MANUFACTURER'S INSTRUCTIONS.

WARNING -- THIS APPLIANCE MAY DELIVER WATER AT HIGH TEMPERATURES. REFER TO THE PLUMBING CODE OF AUSTRALIA (PCA), AND ALL LOCAL REGULATIONS ON ADDITIONAL DELIVERY TEMPERATURE CONTROL MUST BE FOLLOWED.

1. The water heater must be installed:
   • by licensed tradespeople.
   • in accordance with all local codes and regulations and standards including AS/NZS3500.4, AS/NZS 3000, and the Plumbing Code of Australia (PCA).
2. The inlet water pressure of water supply must be between 100kPa – 500kPa. ℹ️
3. Inlet water connections: An isolating and non-return valve must be installed on the inlet to the appliance. If the supply pressure could exceed 500kPa, a pressure limiting valve must be installed on the cold-water inlet. If a cold water expansion control valve (ECV) is required by local regulations, a valve of a maximum of 600kPa can be fitted. The correctly sized pressure limiting valve should also be fitted as per the ECV manufacturers specifications. If no ECV is fitted, a pressure limiting valve of a maximum of 500kPa should be fitted. ℹ️
4. The cold-water inlet to the appliance must have a line filter, non-return valve and isolating valve fitted. Combination valves of these functions are also suitable. ℹ️
5. Outlet water connections: A thermostatic mixing or tempering valve must be used when hot water is supplied to fixtures used for sanitary use (i.e. bathrooms) according to AS/NZS 3500.4 requirements. ℹ️
6. For ease of assembly and disassembly of the appliance, it is recommended that mechanical joints are used to connect to the water heater. ℹ️
7. The water inlet and outlet pipes must be fitted to as per the labels at the hot and cold-water connections. ℹ️
8. To avoid damage to the appliance, the inlet water temperature should remain between 10-40°C. ⚠️
9. Before filling the tank, make sure that the cold-water inlet and hot-water outlet of the appliance are open, along with the farthest hot water fixture. The appliance will be correctly filled once water flows continuously from this fixture without air bubbles. Venting through the PTR could cause premature failure of the valve. ℹ️
10. If there is a risk of freezing, hot and cold water pipes connected to the appliance must be insulated with 20mm insulation. Failure to adhere to this may result in a voided warranty if damage due to freezing occurs. ⚠️
11. In accordance with safety rules, a PTR valve (700kPa, 99°C, Rp3/4") must be installed directly into the PTR valve connection on the appliance. Never block the outlet of the safety valve or its drain line for any reason. ?
