The AMI/MIA/CIA series of Moisture Indicators are
designed to monitor the moisture content within the
liquid line of a Refrigeration system. When the liquid
line is empty, circles may be seen in the glass (only
AMI). However, when the liquid refrigerant touches
the glass, the circles disappear indicating the system is
fully charged.
• Maximum working pressure PS:
AMI: 35 bar, MIA: 45 bar, CIA: 60 bar
Test pressure PT:
AMI: 39 bar, MIA: 49,5 bar, CIA: 66 bar
• Medium temperature TS : -40 to 100 °C
• Compatibility :
Refrigerants: R134a, R22, R404A, R407C, R410A
(MIA/CIA only), R507, R744 (CIA only). Not
suitable for R11 or Ammonia.
Oils: Mineral, Alkyl benzene and ester lubricants.
• Marking:
,
UL, CSA (AMI except AMI-3, MIA - except
MIA-078), Products with connection >32mm
belong to Cat. I of the PED 97/23/EC and are
-marked
• Standards: prEN 12 178
!
S a f e t y i n s t r u c t i o n s :
• Read installation instructions thoroughly. Failure
to comply can result in device failure, system
damage or personal injury.
• It is intended for use by persons having the
appropriate knowledge
attempting to install the indicator, make sure
pressure in system is brought to and remains at
atmospheric pressure.
• Do not release any refrigerant
atmosphere.
• Do not use any other fluid media without prior
approval of Alco Controls. Use of fluid not listed
could result in change of Hazard Category of the
product and consequently change of conformity
assessment requirement
accordance with European Pressure Equipement
Directive 97/23/EC.

Series AMI / MIA / CIA
• In a severely contaminated system, avoid
a n d t e c h n i c a l
breathing acid vapors and avoid contact with
skin from contaminated refrigerant / lubricants.
Failure to do so could result in skin injury.
• AMI/MIA/CIA are not released for use with
flammable refrigerants such as hydrocarbon
refrigerants and ammonia.
• AMI/MIA: UL-requirement: The design pressure
marked on this component shall not be less than
the installed system working pressure or less
than the values outlined in ANSI/ASHRAE 15
for the charged refrigerant. After charging,
mark
refrigerant type and oil used.
M o u n t i n g l o c a t i o n :
• AMI/MIA/CIA has to be installed only in the liquid
line, otherwise the humidity reading can show
wrong values.
• AMI/MIA/CIA is bi-directional and may be installed in
any position which allows visual access to the indicator
window itself.
• The Moisture indicator is normally located after the
filter drier and before the solenoid valve.
I n s t a l l a t i o n :
• Do not remove seal caps until ready for installation.
• The seal caps should be removed with care to avoid
damaging the extension tube connections.
• To avoid oxidization, it is advised to purge the
system with an inert gas such as nitrogen while
brazing.
• Do not exceed the maximum temperature of
100°C.
• The lens assembly on AMI "SS" models should be
removed before brazing. Do not exceed 8 Nm (70
and skill. Before
inch lbs) when reassembling to avoid damaging the
"O" ring seal.
• The MIA/CIA are fully hermetic and cannot be
disassembled.
into the
• When brazing, direct the flame away from the main
body. If in doubt about temperature, use wet rags or
other suitable heat protection (see Fig. 1).
• To avoid overheating it is advised to make the joint
at one end and cool the indicator completely before
repeating the procedure on the other end connection.

• Test for leakage on connections after completion of
installation.

Warning: Failure to do so could result in loss of
refrigerant.
L e a k a g e t e s t :
After completion of installation, a pressure test must
be carried out as follows:
-according to EN378 for systems which must
comply with European pressure equipment directive
97/23/EC
-to maximum working pressure of system for other
applications
W a r n i n g :
the
Failure to do so could result in loss of refrigerant
and person injury.
The pressure test must be conducted by skilled
persons with due respect regarding the danger
related to pressure.
H u m i d i t y R e a d i n g :
• The humidity content in mg Water per kg refrigerant
(ppm) can be identified by the colour code in Fig.2.
• A minimum period of 12 hours is recommended
after installation before attempting to determine
system moisture content
• In case of indicator is showing fuchsia or rose
colour the change of the Filter-Drier is required.
M a i n t e n a n c e / S e r v i c e :
• Before any service shut down system and disconnect
from power source.
• Fully depressurize AMI/MIA/CIA. After reducing
pressure to atmospheric the AMI may be opened and
internal parts removed and replaced.
• In case of repair work or replacing the lens assembly
on AMI always use new gaskets.
• MIA/CIA can not be repaired and must be replaced
by new one's.
