• Check the cylinder banks. Dismount the cylinder
head, check the valve plate and replace it, if neces-
sary.
NOTICE
!
!
Risk of damage to the compressor.
Tighten screws and nuts only to the prescribed
tightening torque and, if possible, crosswise in
at least 2 steps.
Perform a tightness test before commissioning!
7.3 Measures to be taken in case of inadvertent CO

emission

DANGER
CO is an odourless and colourless gas and
2
cannot be perceived directly in case of emis-
sion!
Lost of consciousness and danger of suffocation
by inhaling higher concentrations!
Avoid CO emission and uncontrolled deflating,
2
particularly in closed rooms!
Aerate closed machine rooms!
Make sure that the safety regulations in accord-
ance with EN 378 are complied with!
DANGER
Liquid CO evaporates quickly, cools down at
2
the same time and forms dry ice!
Danger of cold burns and frost bites!
Avoid uncontrolled deflating of CO
When filling the system with CO
and goggles!
If uncontrolled CO emissions occur, take the following
2
measures:
• When gas is emitted, leave the room immediately,
warn people and guarantee a sufficient aeration.
• Do not enter the zone without a self-contained
breathing apparatus as long as the harmlessness of
the atmosphere has not been proven.
• Stay outdoors on the wind-facing side. Block the
area.
• Replace the pressure relief valves of the com-
pressors after deflating because the opening pres-
sure may be reduced after this procedure.
• After the deflating, check the tightness of the safety
valves and replace them, if necessary.
