3.6 Vibration
Vibration that exceeds a specific range may
cause the failure of MCHE . To avoid failure due to
vibration:
•
Make sure vibration level meet require-
ments as in table 2 .
It is recommended to test on points that in the
area within 10mm to the end of the connection
tube (Fig 9)
Best practices in the case to prevent the MCHE
from the influence of vibration is using rubber
washers on the brackets or rubber supports on
the manifolds (fig .10a&10b)

Leak repair
is not practical to repair a MCHE refrigerant leak
in the field . Danfoss recommends replacement
of the MCHE in the event that a leak develops It
due to a defect, mechanical damage or prema-
ture corrosion .
