Condensate Management
1. Prepare a water drainage channel around the foundation, to drain waste water from around the unit.
2. If the water drainage of the unit is not easy, please build up the unit on a foundation of concrete blocks, etc. (the height of the foundation should be a maximum of 150mm).
3. If you install the unit on a frame, please install a water-proof plate within 150mm of the underside of the unit in order to prevent the invasion of water from the lower direction.
4. When installing the unit in a place frequently exposed to snow, pay special attention to elevate the foundation as high as possible.
5. If you install the unit on a building frame, please install a waterproof plate (field supply) within 150mm of the underside of the unit in order to avoid the drain water dripping.

– The power cable is not supplied with Air to water heat pump.
– Supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (Code designation IEC:60245 IEC 57 / CENELEC:H05RN-F).
– This Equipment complies with IEC 61000-3-12.
– For the power Cable, use the grade H07RN-F or H05RN-F materials.
Wiring Diagram of Power Cable
You should connect the power cable to the power cable terminal and fasten it with a clamp. To protect the product from water and possible shock, you should keep the power cable and the connection cord of the control kit and outdoor units within ducts. (with appropriate IP rating and material selection for your application)
Ensure that the main supply connection is made through a switch that disconnects all poles, with a contact gap of a least 3 mm.
Devices disconnected from the power supply should be completely disconnected in the condition of the overvoltage category.
Keep distances of 50mm or more between power cable and communication cable.
If there is a risk of disturbance to the communication cable, a screened cable must be used.

Communication Cable Specifications
If there is a risk of disturbance to the communication cable, a screened cable must be used.
Piping WorkFlow sensor
Supplied with the Pre Plumbed cylinder is a Flow Sensor and a Flow Meter. The Flow Sensor should be mounted within 2 M of the Control Kit. This lead can be extended, it is a 4 core cable, if you do extend ensure that the cores are not crossed. The sensor must be located indoors as it is only splashproof. Ideally, the Flow sensor will be mounted horizontally in the return line to the Outdoor unit. The minimum straight pipe on the inlet and outlet of the flow sensor must be adhered to, as detailed in the diagram The flow sensor plugs directly onto the MIM unit on Connections CSN 057.
Pressure Relief Valve
The outdoor unit does not have a pressure relief valve incorporated. The installer MUST ensure the system is protected from over-pressurisation. The valve shall prevent abnormal water pressure from damaging the system by opening at a maximum pressure setting of 3.0 bar.
Filter/Strainer
Installation of the filter/ strainer is essential to protect the outdoor unit from system debris.
The filter/ strainer must be cleaned regularly to maintain the minimum system flow rate.
Piping Insulation
Pipe or duct insulation should comply with BS 5422:2009. Alternatively, insulation of a thickness that provides reduction of heat loss equivilant to material having a thermal conductivity of 0.035 W/mK at 40 °c and thickness equal to the diameter of the pipe (or 40mm, whichever is smaller) may be used.
