11 - MAIN COMPONENTS OF THE UNIT AND OPERATING CHARACTERISTICS
11.1 - Compressors
The units use hermetically sealed scroll compressors.
Each compressor is equipped with a crankcase oil heater, as
standard. There is no heater fault detection.
Each compressor sub-assembly has:
-
Anti-vibration mountings between the unit chassis and the
chassis of the compressor sub-assembly,
-
A safety pressure switch at the discharge line of each circuit
-
Restrictors (not visible) on the suction pipes (for 3 and 4
compressor modules) to ensure oil level equalisation between
all compressors,
-
Pressure and temperature sensors at the common suction
line and a pressure sensor at the common discharge line.
11.2 - Lubricant
The compressors installed on the units have an oil charge,
ensuring good lubrication under all operating conditions. The oil
level check can be done:
-
On the system: the oil levels must be greater than or equal
to half of the sight glass.
-
A few minutes after the sub-function has come to a complete
stop: the oil levels must be visible in the sight glasses.
If this is not the case, there might be a leak or an oil trap in the
circuit. If there is an oil leak, find and repair it, then refill with
refrigerant and oil.
See the Service Guide for the oil removal and refill procedures.
too much oil in the circuit can cause the unit to
malfunction.
NOTE: only use oils which have been approved for the
compressors. Never use oils which have been exposed to air.
polyolester oils are completely incompatible with
mineral oils. Only use the oils specified by the
manufacturer.
11.3 - Air-cooled exchanger
The coils on the units are composed of aluminium airfoils
crimped onto internally grooved copper tubes (RTPF).
11.4 - Fans
Each fan motor is equipped with a high-performance impeller made from a recyclable composite material. The motors are three-
phase, with permanently lubricated bearings and class F insulation (rated IP55).
For more detailed information, refer to the requirements in the table below. According to regulation No. 327/2011 implementing
directive 2009/125/EC with regard to eco-design requirements for fans driven by motors with an electric input power between 125
W and 500 kW.
