Installation of Outdoor Unit
The heat pump should be installed on a solid level base that can take the weight, preferably a
concrete foundation. If concrete slabs are used, they must rest on asphalt or shingle.
The heat pump should not be positioned next to sensitive walls, for example, next to a bedroom.
Also ensure that the placement does not inconvenience the neighbours. The heat pumps must not
be placed so that recirculation of the outdoor air can occur; this causes lower output and impaired
efficiency.
Large amounts of condensation water as well as melted waters from defrosting can be produced.
Condensation water must be led off to a drain, soakaway or similar.
The outdoor unit should be installed in a ventilated place, with enough space for air inlet and outlet,
while without thermal radiation or other heat source. The air outlet should not be against the wind.
Generally, horizontal air flow type heat pump does not need sheltering. The structure design has
protected all internal components against rain and sunshine. A shelter is necessary to avoid snow
burying the heat pump in heavy snow areas.
Please make sure the standardized voltage 220V-240V is available to the heat pump, otherwise the
performance would be influenced and could affect your warranty.
The foundation of the heat pump can be a cement or steel structure.
Anti-vibration rubber feet and a flat foundation are generally required.
The foundation structure can be flexibly designed according to the
working weight of the heat pump. (Please see the technical data in this
manual.)
Water drainage should be available near the installation location for
draining water in an effective way. Do not install the heat pump in a
place where there is polluting or corrosive materials like oil, flammable
and explosive gas and sulphide ect. Keep it far away from sands, falling
leaves and area with high-frequency equipment.
Installation on a balcony or on a roof-top must be in accordance with the
allowable stress of the building structure.

11 | P a g e
The installation space should be referred as follows:
Intake and outlet should not be obstructed. The wall the unit is to be mounted on should be strong
enough to bear the weight and vibrations of the unit.
Allow for proper clearances around the unit. Location should allow easy access for maintenance.
For any further guidance on heat pump installations for planning purposes, please consult the latest
version of the MCS guidelines or your local authority.

Flexible pipe fittings are recommended to be installed on the flow and return connections.
(Figure 5)
The water inlet and outlet connections to the heat pump, accept standard BSP threaded fittings.
CAUTION –Make sure that the required water flow rates can be maintained at all times.
Plumbing Installation Requirements
1. Water pressure should not exceed 3 Bar.
2. Each part connected to the unit needs to be connected with method of loose jointing and
installed with intermediate valves.
3. Ensure that all plumbing has been properly flushed and tested.
4. All pipelines and pipe fittings must be insulated to prevent heat losses.
5. Install a drain valve at the lowest point of the system to enable the system to be drained
fully.
6. Install a check valve on the water outlet connection if back siphoning could occur.
7. In order to reduce the back pressure, the pipes should be installed horizontally.
8. Install an automatic bypass valve when connecting directly to a system (no buffer).
9. Minimum flow rates detailed on the date badge must be maintained and could void
warranty and damage unit if they are not.

16 | P a g e
Electrical Connections
WARNING –Risk of electrical shock or electrocution.
Ensure that all high voltage circuits are disconnected before commencing heat pump installation.
Contact with these circuits could result in death or serious injury to users, installers or others.
CAUTION –Label all wires prior to disconnection when servicing the heat pump. Wiring errors
can cause improper and dangerous operation. Check and ensure proper operation after servicing.
General Information
Wiring connections must be done according to the wiring diagram found on the inside of the heat
pump access panel or see addendum A for reference.
The heat pumps must also be earthed. A ground lug is provided on the inside of the heat pump
electrical compartment.
The supplied controller is pre-wired using a low voltage low loss cable and can be easily moved and
located where required.
The controller plugs directly onto the cable supplied with no additional wiring required.
If you wish to extend this cable or any of the sensor cables, please use a shielded low loss cable.

Wiring Diagram
CE-iH6-18

18 | P a g e
Power Supply
1. If the supply voltage is too low or too high, it can cause damage and/or result in unstable
operation of the heat pump unit, due to high in rush currents on start up.
2. The minimum starting voltage should be above 90% of rated voltage. The acceptable
operating voltage range should be within ±10% of the rated voltage. When heat pump units
are installed in parallel, ensure that the voltage difference, between these units, is within
±2% of each other. The voltage difference between phases of a three-phase power supply
should be within ±2%.
3. Ensure the cable specifications meet the correct requirements for the specific installation.
The distance between the installation site and the mains power supply will affect the cable
thickness. Follow the 17th edition wiring regulations to select the cables, circuit breakers and
circuit breakers.
Earthing and Over Current Protection
In order to prevent electrical shock in case of leakage from unit, install the heat pump according to
current electrical wiring regulations.
1. Do not frequently interrupt the voltage supply to the heat pump as this may result in a
shorter life expectance of the heat pump.
2. When installing over current protection, ensure that the correct current rating is met for this
specific installation.
3. The compressor, fan coil unit and heat pump water pump all have AC- contactors and
thermo relay protection. Therefore, in the process of installation and debugging, firstly
measure each of the components’ current, and then adjust the current protection range of
the thermo relays.
