i-KI Commissioning with Nadi Controller
This document must be read in association with the i-KI installation manual provided with the
unit. The purpose of this document is to assist with the commissioning of the heat pump. It is
essential the manual is read and followed to ensure the installation is per manufacturers
criteria.
There are various systems/set ups the Heat Pump can be installed to. This document will

Prior to Commissioning
A) Ensure the heat pump is installed in accordance with the installation manual.
B) Ensure the power is isolated to the unit
C) Remove the side cover of the unit to expose the water pump, compressor and electrical
enclosure.
D) Check that the water pump on the unit is free to turn and not seized. In addition please
check any internal pumps.
E) Fill the system with water and ensure all air is removed.
2. Fill the system with water
The system can now be filled with
water to around 1 bar pressure.
