INSPECTION AND MAINTENANCE
6 720 803 687 (2012/11)48
All inspection and maintenance activities must be carried out in such a
way that personal safety is ensured and damage to property is avoided.
This includes the following:
▶ Shut off the gas supply prior to any work on the heat source.
▶ Isolate the system from the power supply.
▶ Never touch the parts of the refrigerant circuit with bare hands during
operation. The refrigerant pipes are very hot or very cold depending
on the condition of the flowing refrigerant.
▶ Never touch any switch or parts of the electrical system with wet
hands. There is risk of electric shock.
▶ Observe the specified processes and delays when starting and
stopping the system. Inappropriate ramping down of the appliance
can result in damage.
▶ After stopping operation, wait at least 5 minutes. Interrupt the power
supply to the hybrid manager and the external unit no sooner.
Damage may occur through escaping water or appliance faults if the
[specified] delays are not observed.
9.2 ENTER INTO AN INSPECTION AND MAINTENANCE
CONTRACT
▶ After replacing components, always check for leaks in the refrigerant
circuit and carry out function tests.
▶ Any O-ring or gasket that appears damaged must be replaced.
▶ When reassembling the hydraulic parts, ensure there is no dust or
debris stuck to the O-rings.
▶ Tighten all connections thoroughly after service to avoid any water
leaks and stop connections from coming loose during operation.
▶ Check all bolts, screws and cables are assembled correctly before
starting the system after any service work has been carried out.
▶ When the work is finished, reset the controls to the original settings.
9.3 MAINTENANCE INTERVALS
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.arranged, severe losses may
occur on the external unit.
▶ Switch the power supply to the external unit 'live' for at
least 12 hours prior to switching the hybrid manager
'live' ( chapter 6.2.1, page 33).
