Congratulations for purchasing a Siddons Solarstream Macon energy efficient Heat Pump
Water Heater, designed for Australian conditions and to produce many years of low energy
hot water. In simple terms, this water heater typically uses just one quarter of the energy of
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. It works very well in all types of
weather, from a tropical monsoonal down pour to a Southerly winter gale. You can expect
around 20% greater efficiency per 10 degree rise in the ambient air temperature.

Siddons Solarstream Pty Ltd, with its partners, designs and manufactures energy efficient
Heat Pump Water Heaters for global markets. The Siddons Solarstream Macon range are
all-in-one heat pump water heaters in a Compact design with heat pump and water storage
tank integrated.

With a Solarstream, you are greatly assisting the reduction of global greenhouse gas emissions
because a conventional electric element water heater typically consumes about one third of
a household's power usage. In fact, if you want your water heater to become completely carbon
neutral, then also install a small electricity generating system. 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 degrees 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 the gas up to
95 degrees C and this heat is then pumped into the water via the dynamic cycle heat exchanger
to produce hot water very efficiently.

Solarstream can also be used for factories, schools, hotels, motels, restaurants, hospitals,
laundries, etc.

A dynamic cycle flow heating system is used that uses just 1 kW/h of electrical
energy to produce around 3.5 kW/h of heat into the storage tank, more or less depending on
ambient air temperature and humidity.

2.1 Storage tank

Solarstream uses a high quality, marine grade (316) stainless steel storage tank as standard.

2.2 Heat Exchanger

The heat exchanger is an efficient, double skinned, tube in tube design. A quality Grundfos
circulating pump is used to cycle all of the tank water through the heat exchanger. All
components of the heat pump come from the best global suppliers.

2.3 Centrifugal Fan

Your Solarstream has a centrifugal fan, which enables it to move air powerfully across the
evaporator coils for efficient phase change of the refrigerant from liquid to gas for excellent
heat pump performance. You can also attach a duct to the air outlet to make use of the cool
outlet air if you want.

2.5 Dynamic cycle flow heating system

Your Solarstream has a dynamic cycle flow heating system that systematically cycles all of the
tank water through the heat exchanger to leave no cold spots so that all of the hot tank water
can be delivered. The superheated compressed gas circulates through a double layered,
outside coil whilst the tank water circulates through an inside coil. The heat from the outside
coil is transferred to the inside coil then circulated back into the tank. New cold water is
extracted from the bottom of the tank then cycled dynamically through the heat exchanger
until the controller picks up the signal from the tank sensor to stop heating. The advantages
of this method are: heating efficiency, stable hot water without over heating the top or under
heating at the bottom of the tank and all of the tank water will be heated.

2.4 Installation overview

To install your Solarstream, site the unit and
ensure it will remain in a vertical position throughout its usable life and not lean over due to
possible erosion of soil under the plinth, or such risk. Adhere to the relevant plumbing
regulations in regard to the water heater installation. We recommend fixing the tank to the
adjacent wall as an added safety precaution. Use only quality plumbing components such as
those supplied in the Siddons QIK kit. Connect the water supply. Refer Section 4 for details.
Plug in the 15 Amp power lead to a 15 Amp outlet or ask your electrician to hard wire into an
off peak or Smart meter. Your Solarstream will provide reliable 60 degree hot water for many
years.

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

4.3 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 but must not be connected directly to the PTR valve or expansion valve drain.

4.2 Air Flow

The heat pump extracts heat from air, drawn through the Fin Coil. This produces cold exhaust air
as the heat from the air is absorbed into the refrigerant. In order for your Solarstream to operate
efficiently, good ventilation for the air inlet of the evaporator is required with the warmest possible
air. The cold exhaust air should not be allowed to feed back into the inlet or operational efficiency
will be reduced. The heat pump is therefore best located externally, in a well vented location and
not facing into a prevailing wind. However, alternate locations can be used such as a large double
garage (minimum of 120 cubic metres) may also be suitable.

Corrosion Protection
Fittings to the casing in contact with the water must be galvanically compatible. Sealants and / or
Teflon plumbing tape should be used on potentially galvanically incompatible fittings. This is to
protect against possible electrolytic corrosion between the metals (where moisture penetration
could occur due to incorrectly or poorly sealed fittings).
