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
covers the most common options:
Pre-Commissioning
B. Underfloor with Aube Thermostat
C. Underfloor with Aube Thermostat and DHW
D. Underfloor with Buffer Tank, Aube Thermostat and DHW
E. Underfloor with Nadi Controller

1.
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.
The iKi heat pumps have a pump
run switch on the small PCB
under the front cover of the heat
pump on the smaller heat pumps,
and under a panel on the side of
the larger models. This allows
the circulation pump to be run
manually to help vent the system.
Leave the unit on standby for 2 hours once filled.
Before the heat pump runs for the first time it is necessary to let it stand for 2 hours
with the power on. This is to allow the heating band around the compressor to heat
the compressor to drive off any liquid refrigerant in the compressor. This is
