COMMISSIONING
6 720 803 687 (2012/11) 33
6.2 COMMISSIONING THE SYSTEM FOR THE FIRST TIME
6.2.1 PROVIDING THE EXTERNAL UNIT WITH A POWER SUPPLY
AHEAD OF COMMISSIONING
The BUS cable is not connected at this point so the outdoor unit can be
powered on for the 12 hour period.
After the 12 hour period, the power to the outdoor unit can be briefly
interrupted (i.e. 5 minuets) to allow connection of the BUS cable to
the hybrid manager.
Once the BUS cable from the outdoor unit has been connected to the
hybrid manager the outdoor unit and the hybrid manager can be
powered on (within 3 minutes of each other).
6.2.2 PROVIDING THE EXTERNAL UNIT WITH A POWER SUPPLY
DURING COMMISSIONING
All units must be powered up within a 3 minute time period to prevent
any communication issues, therefore there will be a need to interrupt the
power supply to the external unit upon commissioning.
6.2.3 CONNECTING THE CANBUS CABLE TO THE HYBRID
MANAGER UNIT
Interrupt the power supply to the external unit.
Undo screws at the top and bottom of the appliance.
Remove casing.
Undo fixing screw on the left [1] of the hybrid control module.
Push out the spring plate [2] and tilt the hybrid control module
forward.

Undo three screws and remove the small cover for the internal
connections at the back.

To provide splashed water protection (IP), always trim the strain relief
fitting in accordance with the cable diameter.
Fig. 42 Trimming the strain relief
Guide the BUS cable through the strain relief fitting and connect it to
terminals S2/S3.

Refit the cover after connection.
Re-establish power supply to external unit
6.2.4 MAKING THE POWER SUPPLY CONNECTION
Connect the2m pre-installed flexible cable on the hybrid manager unit
to the power supply (230 V AC, 3 A).
6.2.5 SWITCHING ON THE HYBRID SYSTEM
Ensure that the shut-off valves on the liquid and gaseous refrigerant
pipe work are open.
Make the power supply to the hybrid manager and the external unit.
The external unit's compressor runs for 5 minutes at stage 1 (self-
test).
Check whether system components start correctly.
NOTICE: Damage when starting the compressor in the
external unit from cold!
For commissioning:
The Power supply to the external unit must be
“Live”for at least 12 hours before starting operation.
This is to ensure that the compressor is warmed up
sufficiently to avoid any liquid refrigerant from
entering the compressor. This is particularly
important during colder periods.
The 12 hour period also compensates for any
unsettling of the lubricating oil within the compressor
which may have occurred during transportation.
If this 12 hour time period cannot be met damage to
the outdoor unit may result.
