6.1 Faults and corrective actions
Problem Possible faults Corrective actions
The compressor starts up with
lag. There is a slow build up in
the electric
motor’s speed.
The belt is overtightened
Tighten the belt with the rel-
evant load.
The oil is thick. Replace the oil.
There’s a whistling during the
compressor’s operation.
The belt is slipping.
Tighten the belt with the appro-
priate tensile force (see section
5.3 Checking drive belt).
The compressor won’t start.
There’s a temperature block on
the control unit’s display.
The ambient air temperature in
the facility does not meet the
required temperature (below
+5 °C or above +40 °C).
Ensure the necessary ambi- ent
air temperature where the com-
pressor is installed.
The compressor is overheating.
There’s insufficient ventilation in
the facility where the compres-
sor is installed.
Increase the air circulation
inside the facility.
The oil level is too low. Top up oil.
The radiator is dirty Blow down the radiator with
compressed air.
The safety-relief valve of the
separator tank is activated.
The separator is dirty.
Perform maintenance by
replac- ing the separator.
The pressure is too high
(over13 bar). Set the working pressure

Storage and disposal
7.1 Storage conditions
The compressor should be kept at a temperature between - 20° and +35°С with max. 85%
relative humidity.
7.2 Disposal of oils and process condensate
Used oils, greasy filters and separators should be recycled in a sealed container and dis- posed of
at a local recycling or disposal facility. Do not allow precipitation to mix with oil. Process condensate
contains oil. Local environmental regulations govern the degree of contamination of condensate
discharge into sewers. Use process condensate separators to separate oil and further impurities
from condensate.
Replaceable components of a process condensate separator should be disposed of in the same
way as greasy wiping cloths.
