for indoor installations, please ensure that the chosen location
complies with the requirements outlined in AS/NZS 5149.
• Make sure there is ample space for installation and maintenance,
with a recommended minimum vertical distance of 300mm.
• The product must be installed in a dry environment free from
humidity.
• Ensure that the supporting surface is level (with a horizontal angle
not exceeding 2°) and capable of bearing the weight of the heat
pump when filled with water. Refer to the technical data for the
heat pump's weight.
• Choose a suitable outdoor location for the exhaust air vent, and
be sure to insulate the exhaust air ducting to prevent condensa-
tion when the system is in operation.
• Ensure there is easy access to the system for maintenance pur-
poses.
• Always provide extra space for pipe connections and power
cables.
• Avoid installing the product on a surface with loose coverings,
as it may produce excess noise during operation.
• Avoid installing the product in areas with toxic gases or mineral
oils, as these locations are not suitable.
• When installing near a coastline within 500 meters, be mindful
that extra maintenance may be necessary. Insucient shelter
from coastal conditions can shorten the system's lifespan and
potentially void the warranty.
If you install the product in an environment prone to frost,
take all necessary precautions to ensure proper insulation
of all pipework.
TRANSPORTING THE HEAT PUMP
• To ensure the warranty remains valid, it's crucial to store and
transport Emerald heat pumps in an almost upright position with
a tilt angle of no more than 30°. Storing or transporting the unit
horizontally will void the warranty.
• Always transport the system while it's inside it's packaging.
• The packaged system weighs 138KG for models EE-HWS-A1-220
and EE-HWS-A1-220E, and 156KG for models EE-HWS-A1-270 and
EE-HWS-A1-270E. For safe handling and to prevent damage, it's
necessary to have two people carry the system at all times.
• Please be aware that the external casing of the unit is prone to
denting and damage. When moving the unit, exercise care and
caution, as any marks caused by improper handling are not
considered defects and are not covered under the warranty.
MINIMUM INDOOR INSTALLATION
REQUIREMENTS
• The indoor area for heat pump installation should exceed the
following sises:
For a 220L unit, the area should be at least 67m².
For a 270L unit, the area should be at least 47m².
For a 320L unit, the area should be at least 29m²
• If the heat pump must be installed in a smaller indoor space but is
connected to an adjacent room, there must be a fixed open door
connecting the rooms. A fixed open door cannot be closed under
any circumstances.
• Place heat pumps a safe distance away from potential ignition
sources or corrosive environments to prevent the risk of fire or
damage.
• Consider the serviceability of the heat pump during installation,
ensuring there is enough space for maintenance and repair tasks.
• Follow all relevant electrical and safety standards during.
• Regularly perform maintenance and inspections on both the heat

INSTALLATION OF THE HEAT PUMP
1. BASE
• The unit must be installed on a concrete plinth or a stable structure
capable of supporting weights exceeding 400kg. It's crucial that
the supporting structure remains stable over time and does not
shift, especially due to factors like water drainage. You'll need
a concrete base that's at least 50mm thick or a well-seasoned
hardwood slat with a minimum thickness of 25mm. If you're using
concrete base pavers, make sure they have a minimum dimension
of 600mm x 600mm.
• Make sure all four feet of the unit are supported by the base you're
using to avoid any potential warranty issues.
• Ensure proper drainage is in place to handle any potential
overflow.
• During installation, it's essential to position the unit completely
vertically and level to facilitate proper condensate drainage.
If the system is installed with a tilt exceeding 3° it could void the
warranty.
• If there's a risk of property damage due to water leakage, you must
install a safety tray, also known as an overflow tray.
2. AIR FLOW
• Do not install the unit in areas where there is a risk of falling
debris, such as leaves, as this could block air vents or cause
damage to the unit.
• Avoid placing the system in locations with multiple walls or
structures.
• When installing the unit under fixtures or home eaves, follow
these clearance requirements:
- Maintain a minimum clearance of 300mm above the unit.
- Provide a 600mm clearance to the right side of the system
(when facing it).
- Allow for a 150mm clearance to the left side of the system
(when facing it).
- Position the unit at least 150mm away from your home's wall to
ensure full access for servicing and to prevent cold air circulation.
• Install the unit to ensure that the control interface is easily
accessible for users. There should be clear access to the
electrical panel located at the back of the system. Improper
installation could result in voiding the warranty or require
additional charges to rectify the system's compliance.
WARNING
• A minimum of 20m3 of unobstructed space surrounding the unit.
• For indoor installations the ensure that the location complies with
the requirements of AS/NZS 5149.
• The electrical access point and display panel should always be
accessible.
VENTILATION GUIDELINES:
These guidelines pertain to the proper operation of the heat pump
and are not related to the storage of flammable refrigerants. It's
important to ensure that the location complies with AS/NZS 5149
requirements.
Ideally, the heat pump should be installed outdoors. However, for
indoor installations, it's crucial to be aware of potential issues and
take preventive measures.
One significant concern with indoor installations is the risk of air
recirculation. In confined spaces, the air temperature can gradually
decrease, leading to a decrease in the heat pump's eciency and,
in some cases, even failure.
To prevent this, make sure the ambient air temperature doesn't drop
below 5°C. Continuously monitor the air temperature within the space
to ensure adequate ventilation throughout the heat pump's lifetime.
To maintain a stable air temperature, consider the following
recommendations:
• For indoor installations, choose spaces with an air volume greater
than 53m³.
• If the area is smaller than 53m³, ensure cross ventilation. Cross
ventilation can be achieved either naturally or mechanically.
• Natural ventilation occurs when there are appropriately sized
openings on opposite ends of the enclosure, facilitating cross
airflow.
• When using mechanical ventilation through a supply or extract fan,
ensure a minimum air volume of 1000 m³/h (278 L/s).
• In mechanically ventilated areas, establish a make-up air pathway.
This can take the form of grilles, undercut doors, open doors, open
windows, etc.
• To achieve eective cross ventilation, position the make-up air
pathway on the opposite side of the enclosure from the fan.

PLUMBING CONNECTIONS

PLUMBING CONNECTIONS
COLD WATER SUPPLY OUTLET
• The cold water supply connection uses a G 3/4″ female thread.
• To connect the cold water supply, use a G 3/4″ socket.
• The cold water supply outlet can also serve as a drainage point for
emptying the system.
HOT WATER CONNECTION
• The hot water supply connection also uses a G 3/4″ female thread.
• Connect the hot water supply using a G 3/4″ socket.
• To ensure thermal eciency, insulate all hot water lines and
connections with a minimum 13mm closed-cell insulation.
• All hot water supply components must be made of copper.
CONDENSATE DRAIN
• When heat is extracted from the atmosphere through evaporator
coils, it generates condensation in the form of water. In places with
higher humidity, this condensation occurs at a faster rate.
• To collect the water by-product, a condensate tray is placed at the
base of the heat pump. Any surplus water from this tray is chan-
neled through the condensate drain.
• The system comes with a pre-installed condensate drain connection
elbow. It is essential to route the condensate into the nearest storm
water drain using a drainage pipe. Failing to do so could lead to
issues like termite attraction and the growth of algae and moss.
• Ensure that the condensate line is free of kinks, and since the water
relies on gravity for flow, it should only run downward to facilitate
unobstructed water flow.
PRESSURE & TEMPERATURE RELIEF TPR VALVE
• The system comes with a TPR (Temperature and Pressure Relief)
valve that matches the water heater tank's pressure rating. If the
TPR valve is missing, please get in touch with your supplier.
The valve is rated with a capacity of 850kPa, 10kW, and a set
temperature range of 93-99°C.
• Install the provided TPR valve at Point 4, as indicated above.
• Ensure that the TPR valve is insulated with a minimum 13mm
closed-cell insulation to minimise heat loss.
• The TPR should be positioned in a way that the drain line always
points downward, and the discharge point remains open to the
atmosphere.
• When connecting a discharge pipe to the pressure relief valve,
make sure it runs continuously downward and is placed in a frost-
free environment. Do not connect any pressure relief device to the
condensate drain pipe, as water may drip from the pressure relief
device's discharge pipe. This pipe should always be left open to
the atmosphere. Additionally, regularly operate the pressure relief
device to remove lime deposits and confirm it is not blocked.
