4.1 Unit maintenance
Working on the compressor
The compressor is fastened to the platform by four 8 mm diameter screws (or 3 screws depending on the model).
Warning: tighten these screws to a torque of 13Nm +/- 1Nm.
If you do not have a torque wrench, tighten them until they are snug then tighten a further 3/4 turn.
Working on the accelerator pump
The accelerator pumps are equipped with a release screw. It may be necessary to use it when powering the system off for
extended periods of time.
However, the accelerator pumps are EC type. The torque is controlled electronically and therefore should not require much
manual intervention.
Working on the sensors
The LP and HP pressure sensors are accessible via the base of the refrigerating block. There are 2 options for accessing the sensors:
There is no option on the GeoCIATTM Modular. The
refrigerating block's top cover is easily accessible
=> working on the sensors by removing the 2 roof sections.
The HP pressure switch is accessed via the front of the machine.
To access the sensor:
Working on the expansion vessels
The expansion vessels must be re-infl ated every year to ensure optimal
operation.
To do this, close the water inlets and outlets on the heat pump circuits
and undo the fl exible connections on the expansion vessels. Remove the
retaining screws from the mounting bracket and lower the transverse bar.
There is one option with the GeoCIATTM Modular ; the roof is diffi cult
to reach
=> working on the sensors by removing the electrical panel
The pressure
connectors and
sensors are
accessed via
the top of the

The HP pressure switch is held on
the capillary tube by a clip
The pressure
connectors and
sensors are
accessed by moving
the electrical panel
to the right after
unscrewing the panel
retaining screws and
removing cables
which are too short.
