Use the white float to check the amount
of coolant.
Some loss of coolant through the hoses in the climate
control system is unavoidable. Check the coolant level
every 100 hours. To do this, keep the engine running and
the climate control system switched on (and turned to
maximum cooling) and check the inspection window (2) in
the desiccator (1).
• If the white float is at the top, the coolant level is O.K.
• If the white float is at the bottom, you must top up the
coolant (specialised workshop)
Use the blue indicator bead to check the
moisture saturation.
Moisture in the coolant circuit is collected in the filter
desiccator.
• If the indicator bead has a blue hue, the moisture
saturation is O.K.
• If the indicator bead has a pinkish hue, the desiccator
must be changed (specialised workshop).

13.9 Collector / Drier
The ambient temperature must be
above the set thermostat temperature
(u1°C) for the compressor to
switch on.
Since an operating over-pressure is present inside the coolant
collector it manufacturing and testing is subject to the
Druckbehälterverordnung (pressure vessel code).
In this code the pressure vessels are classified according to
the permissible operating over-pressure p in bar, its capacity
in liters and the pressure capacity product p x l into test group
II.
According to § 10 of the Druckbehälterverordnung (pressure
vessel code) these pressure vessels are subject to a recurring
examination by an expert according to § 32. In this case,
recurring examinations consists of external checks, ususally
at vessels which are in operation. The coolant collector must
be checked visually twice a year in connection with the
inspection. Particular attention must be given to coorosion
and mechanical damage. If the proper is not in proper
condition, it must be repaced for safety reasons, to make
sufficient provision for the protection of operators and others
due to the danger during handling or operation of pressure
vessels.
