1 INTRODUCTION
1.1 Safety Considerations
IMPORTANT
DO NOT LEAVE HEAT EXCHANGER EXPOSED TO DIRECT SUNLIGHT.
Prolonged
exposure to UV light can cause severe damage to the structure of the heat exchanger,
and will void the warranty.
WARNING
Improper installation, service, maintenance or use can cause fire, electrical shock or
other conditions which may cause personal injury or property damage and will void the
warranty. Check with Air Change or nearest Air Change dealer for any information
required on this equipment.
DANGER
Electrical shock can cause personal injury or death. Before performing any work on
this equipment, the electrical supply must be turned off at the electrical service box to
avoid the possibility of shock, injury or damage to equipment.
Note: There may be more than one power supply circuit.

1.2 Note to Installer
• Only trained and qualified personnel should install, repair or service air conditioning
equipment. Untrained supervised operatives can perform basic maintenance functions
such as cleaning or replacing filters. Service personnel must perform all other
operations.
• Installing and servicing air conditioning equipment can be hazardous due to electrical
and mechanical components.
• When working on air conditioning equipment, observe precautions in all literature, tags
and labels attached to or shipped with unit. Follow all safety codes and guidelines.
Wear safety goggles, work gloves and any protective clothing.
• All work must comply with relevant SAA wiring rules and local authority codes.
Installers must ensure that all statutory regulations and by laws have been addressed.
• Installers must ensure that the structures built to take the units have been suitably
constructed for the purpose, all safety precautions have been applied prior to
installation, and all preparation work has been constructed and suitably sized for its
purpose.
1.3 Inspection and Unpacking
• The unit should be inspected upon delivery for possible external damage incurred
during transport. If damage is evident it should be noted on the freight docket and the
Air Change sales office contacted. A claim should be lodged with shipping company
within three (3) days if shipment is damaged or incomplete.
• If major damage is apparent, do not lift unit on to site without prior approval from Air
Change. The unit was tested and inspected prior to packing and was in perfect
condition at that time.
• Check unit rating plate to ensure the correct unit matches the job specifications.
1.4 Unit handling
• Protective packaging should not be removed until the unit is at the point of installation.
When removing packaging, be careful not to damage, scratch or dent the unit. After
removal of packaging or crating, all removable access panels should be opened to
inspect for unit internal damage.
1.4.1 Lifting
• Exercise extreme caution when lifting unit. Make careful consideration of the unit’s
centre of gravity and distribute the weight evenly. Test load to see if the weight is
equally distributed. Do this by lifting the unit a few centimetres off the floor and
holding it there before lifting any further or before transporting the unit.

• For further guidance on safe lifting, see the National Occupational Health and
Safety Commission Manual Handling documentation.
2 INSTALLATION
2.1 Location
2.1.1 General
• The prime function of the unit is to deliver pre-conditioned fresh air by transferring the
energy from the already air conditioned stale return air. Therefore the unit must be
located away from a location where the return air can be affected by a heat
source i.e. a frequently opening door to exterior, or near any major source of heat
generation.
•ERV-IC units are design for internal installation and are not weather-proof.
2.1.2 Ductwork considerations
• The unit should be situated centrally, or close to the point of use, to prevent
unnecessary long runs of ductwork.
• Use only the minimum sized ducting for the spigots supplied.
• Acoustic, insulated spiral ducting is preferred for quietness and performance.
2.1.3 Inlet/Outlet precautions
• The exhaust discharge should be ducted to outside and be directed in a clear path
away from any windows that can be opened.
• Location of the Fresh-Air inlets should adhere to the Australian Standards 1668.2
Code.
• The Fresh-Air intake should be positioned clear of any objects which could obstruct the
airflow and be clear of any polluted air from other units, exhaust fans, kitchen or toilet
exhausts, etc.
• Fresh-Air inlet should be fitted with a weather shelter and inlet and exhaust points
should be minimum 6m apart.
2.2 Installing the Unit
• Before suspending the unit, check the supporting beams to be used to verify that it
has sufficient load carrying capacity to support the weight of the unit.
• Allow 660 mm working clearance on the discharge side of the ERV-IC to allow for
fan maintenance.

• Unit inlet and outlet connections are as follows. The unit can be handed either way.
• Shown below is a typical installation example (ducts supplied by others)
2.3 Electrical/Electronic Connections
2.3.1 Mains power supply and fusing
• A power supply rated at 240V 1 phase, 50Hz is required to operate two fan motors
within manufacturer's tolerances (Models ERV-IC 200-ECP and 400-ECP)
•A power supply rated at 415V 3 phase, 50Hz is required to operate two fan motors
within manufacturer's tolerances (Models ERV-IC 600-ECP, 900-ECP, and 1200-
ECP)

• Mains cables and control circuit wires are to be connected as per wiring diagram
and all wiring must comply with relevant local wiring rules.
•Refer to separate electrical diagrams for electrical connection details.
2.3.2 Electrical Connection and Supply Size Precaution:
• We recommend an isolator be mounted externally to the unit (not supplied) and a
suitably sized fuse mounted back at the distribution board to provide local isolation
during service and maintenance periods, or simply remove plug.

2.4 Ducting
• Ducts should be fitted to the Supply Air, Exhaust Air, Return Air and Fresh Air inlet.
• Fan inlet conditions can affect the fan performance, particularly ducting elbows which
can cause non-uniform inlet flow and swirl at the inlet. To reduce losses due to fan
system effect, adequate length of straight duct between elbow and fan inlet should be
provided or turning vanes used in the elbow.
2.4.1 Duct Sizing
• Please refer to separate unit drawings for duct sizes.

3 SYSTEM COMPONENTS
• The unit employs 100% outside air and comprises of the following components:
3.1 Cabinet
• Prefabricated wall and ceiling panels of are constructed of 1.2mm galvanised sheet
metal, bonded to 12mm polyurethane film faced insulation.
3.2 Fans
• Supply and exhaust fans are backward curved EC plug fans.
3.3 Heat Exchanger
The air-to-air heat exchanger of ERV-IC ECP units is available in the following formats:
• The Energy Reclaim (enthalpy) counter flow enthalpy heat exchanger incorporated into
the unit will reclaim up to 75% of the energy (under normal operating conditions) from
the space return/relief air to outside air, i.e. to pre‐treat the outside air. This results in
a saving of up to 75% on the cost of heating or cooling the outdoor air.
• The Heat Reclaim (sensible) counter flow heat exchanger incorporated into the unit will
reclaim up to 80% of the heat (under normal operating conditions) from the space
return/relief air to outside air i.e. to pre-treat the outside air. This results in a saving up
to 80% on the cost of heating or cooling the outdoor air.
3.4 Filters
• Air Change ERV-IC ECP units incorporate internal panel filters for the outdoor air and
the return air. Refer to the separate unit drawings for filter sizes.
4 Technical Specifications
4.1 Schematic Dimensional Data
• Refer to separate dimensional diagrams for dimensional information.
4.2 Electrical Diagrams
• Refer to separate electrical diagrams for electrical information.
IMPORTANT: If these units are being used during construction when
adhesive, sealers, ducts, new and used carpets are being installed make sure all
equipment is fitted and adequately protected. We recommend using disposable
or temporary filters during commissioning and during pre-hand over running.
