1. One of the World's Most Efficient Ways to Heat Water

Congratulations on purchasing a SIDDONS Solarstream energy efficient Heat Pump Water Heater, designed for Australian conditions to produce many years of low energy hot water. This water heater typically uses up to 75% less energy than a conventional electric element water heater by absorbing heat from the surrounding air of between -5 and 45 degrees C, night and day. It works in hail, rain and shine and becomes more efficient as the air temperature and humidity rise. You can expect around 20% greater efficiency per 10 degree rise in the ambient air temperature.

SIDDONS, with its partners, designs and manufactures energy efficient Heat Pump Water Heaters for global markets using the best quality components sourced from Australia, Germany, Japan and China.

Heat Pump Water Heaters can be used for factories, schools, hotels, motels, restaurants, hospitals, beauty salons, spas, laundries, etc.

1.2 Dynamic Cycle Flow Heating System

The Dynamic Cycle flow heating system is used to convert an average of 1 kW/h of input electrical energy into 3.5 kW/h of heat energy, more or less, depending on ambient air temperature and humidity. Cold water from the bottom of the storage tank is cycled through

the heat exchanger in the Heat Pump outdoor unit then back to the storage tank until all the water is completely heated.

As the name implies, an air to water Heat Pump Water Heater is a machine that pumps or transfers heat absorbed from the ambient air into the water. Even at - 5 deg C, there is enough heat in the air to boil the liquid refrigerant into a gas. Once in the form of a gas, it can be compressed to superheat up to 95 deg C; this heat is then pumped into the water through a double layered, tube inside tube heat exchanger. One tube takes the hot compressed gas whilst the other takes the cold water from the tank. The advantages of this method are:

1.3 Reduce Greenhouse Emissions

With a SIDDONS Solarstream, you are greatly assisting the reduction of global greenhouse gas emissions if you can replace bottled gas, wood fired or a conventional electric element water heater, the latter typically consumes 1/4 to 1/3 of a household's power usage. If you want your water heater to be completely carbon neutral, then also install a small electricity generating system such as a Photo Voltaic solar panel or wind power.

· Excellent heating efficiency

· Stable hot water without over heating at the top or under heating at the bottom

· All of the tank water is heated

2.2 Not suitable for Pools and Spas

Note, this heat pump is not suitable for pool or spa heating due to the high levels of salt and/or chlorine used and volume of water to be heated. If used for such applications, your warranty will be void.

2.3 Heat Pump Positioning

The heat pump extracts heat from the air being drawn through the fin coils of the evaporator. This produces cold outlet air as a by-product. In order for the heat pump to operate efficiently, good ventilation is required to extract the heat from the air easily and therefore the heat pump is best located outside.

The R134a refrigerant used has a boiling point of minus 26 deg C so there is no risk of damage to the heat pump from frost. Performance may be reduced in very low temperatures but the system will not be damaged by such climatic conditions.

The cold exhaust air should not be allowed to feed back into the inlet or operational efficiency will be reduced. The heat pump should not facing into a prevailing wind. However, alternate locations may be used such as a large double garage (minimum of 120 cubic metres).

Note: For water pipe connection instructions, refer section 2.5 below.

2.1 General Installation Requirements

This water heater must be installed by a licensed trades person in accordance with:

1). AS 3500.4, National Plumbing And Drainage Code, Part 4: Hot Water Supply Systems

2). AS 3500.4.2, National Plumbing And Drainage Code, Part 4.2: Hot Water Supply Systems Acceptable Solutions

3). Other relevant Australian Standards, Industry or Local Water Supply regulations or codes for mains pressure storage tanks

Note: This water heater is not suitable for pool heating or building heating.

2. Installation Details

AIR TO WATER HEAT PUMP WATER HEATERAIR TO WATER HEAT PUMP WATER HEATER

Notice:

Wrong Right

1) Keep enough space around the unit for maintenance access with at least 200mm of clear space for evaporator coils so there is good air flow into the evaporator.

2) Ensure the heat pump is sited onto a flat, level surface. Use a 600mm x 600mm concrete slab if the installation base is not solid.

3) Install the metal feet of the heat pump onto the rubber feet supplied and bolt it onto the base.

4) It is a good idea to install the heat pump with some weather protection such as an eave to protect against direct sunlight which may make the fan blade brittle over time.

5) Protect the heat pump from salt spray if near the coast as this will reduce its operating life.

6) Ensure there is space above the heat pump for the outlet air to blow upwards unimpeded.

7) The heat pump and storage tank may be installed on a balcony, roof, floor or other convenient place but you must ensure your site has load-bearing to cope with the weight as specified plus the weight of the water inside the storage tank (1kg per litre).

8) During operation, condensate water will flow from the evaporator so use a length of hose connected to the drain hole elbow to take the condensate water to a drain.

9) If your only option is to locate the heat pump inside a large internal space such as a garage, this space should be well ventilated or the heat pump will turn it into a cool room and your heating efficiency will decrease (keep in mind that a 10 degree C reduction in air temperature will cause approximately 20% lower efficiency).

2.4 Evaporator Drain

During operation, considerable amounts of condensate water will flow from the evaporator drain. If allowed to simply flow out of the outlet, this water may pool below the unit and can cause problems to both the water heater and area around it. The evaporator drain should be properly drained using a length of hose or pipe in accordance with regulations but must not be connected directly to the PTR valve or expansion valve drain.

2.5 Water Pipe Connections

1) Water pipe connections should be heat-resistant, rust-proof, resist fouling and conform to national health and safety standards. The water pipe can be stainless steel pipe, copper pipe, aluminium water pipe, hot water PPR pipes, etc.

2) Ensure all water pipes are clean and rust free to prevent pipe blockage.

3) The water circulating pipes from the heat pump should be installed with the least amount

of bending and distance from the water storage tank for optimum efficiency. We recommend between 2m to 5m as an ideal distance for the water circulating pipes.

4) The water outlet of the heat pump should connect to the of the storage tank.

5) Ensure that all the pipes are tightly connected and test for leaks.

6) Apply insulation onto the pipes and plumbing fittings to minimise heat loss.

2.6 Electrical

SIDDONS water heaters are designed for single-phase 220/240V A/C supply only. A certified electrician must carry out all electrical work in accordance with regulations including AS3000. A 15-amp circuit breaker should be installed at the power supply for the hot water unit.

A separate circuit breaker is recommended for each unit in the case of multiple installations. The connection will require an approved, standard 240V 15A On / Off switch or Junction Box in close proximity to the heater.

Key points:

1) The heat pump should ideally be supplied with a dedicated 240 Volt 15 Amp power supply

2) The heat pump should ideally be connected using a 15 Amp power cable

3) The heat pump power supply circuit must have a grounding wire

4) Power lines and signal lines should be neat and rational, with strong and weak lines separated so they cannot interfere with each other; leave appropriate distance between the lines

5) Electrical maintenance must be done by qualified technicians (refer to circuit diagram below)

6) Unit control panel Code MK4068

7) Fuse specifications: 5A/250V ) The appliance must be installed in accordance with regulations

Connection

isolating

Option A: Single set of water inlet/outlet ports Use a Tee Piece and one-way valve on both pipes to add the water circulating pipe connections between the heat pump and water storage tank.

Option C: Double set of water inlet/outlet ports plus ring main return port Connect the heat pump water circulating inlet pipe to the spare cold water inlet port on the water storage tank with return water flowing back to the middle ring main port.
