Air Chiller System (ACS) and Chiller Panel Getting Started Guide for the DMA 850 Page 51
NOTE: It is important to power off the ACS regularly and purge with dry gas for a period of time, typi-
cally over-night. This prevents build-up of frost inside the ACS, which can slowly degrade the perfor-
mance of the Chiller or even stop operation entirely. It is recommended to power off the Chiller daily when
the ACS is used continually. Some users with exceptionally dry supply air will find that less frequent dry-
ing intervals are acceptable, possibly allowing up to a week to pass between drying cycles.
WARNING: It is always important to keep the end of the transfer line horizontal. Do not allow the
end of the transfer line to droop or hang downward, especially while the Chiller is running or
when the transfer line is cold. This could allow coolant to clog the capillary tube, damaging the
system. If it is suspected the capillary tube may be clogged due to mishandling, follow the
instructions for Shutting Down the ACS found on page 52 of this document. The line may then
be supported vertically for several hours to allow coolant to redistribute throughout the system.
AVERTISSEMENT: AVERTISSEMENT: Il est toujours important de garder la fin de la ligne hori-
zontale de transfert. Ne laissez pas la fin de la ligne de transfert à se faner ou accrocher vers le
bas, en particulier alors que le refroidisseur est en cours d'exécution ou lorsque la ligne de
transfert est froid. Cela pourrait permettre à du liquide de refroidissement à obstruer le tube
capillaire, d'endommager le système. Si l'on soupçonne le tube capillaire peut être obstrué en
raison de la mauvaise gestion, suivez les instructions pour arrêter l'ACS trouvé à la page 52 de
ce document. La ligne peut alors être pris en charge à la verticale pendant plusieurs heures
pour permettre réfrigérant de redistribuer througout le système.
