Installation Of The Heat Pump - Emerald EE-HWS-A1-220 User Manual & Installation Manual

INSTALLATION
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.

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.

To maintain a stable air temperature, consider the following
recommendations:
• For indoor installations, choose spaces with an air volume greater
than 53m .
• If the area is smaller than 53m , 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 m /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.
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.

• 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.
