Emerson ALCO CONTROLS MIA-FLR Serie Manual De Instrucciones

G e n e r a l i n f o r m a t i o n :
MIA...-FLR are sight glasses with moisture indicator.
The listed products are not in scope of ATEX product
directive 2014/34/EU as they do not incorporate an own
source of ignition.
MIA...-FLR must be installed in an appropriate housing to
protect them from mechanical damage or shock.
S a f e t y i n s t r u c t i o n s :
• Read operating instructions thoroughly. Failure to
comply can result in device failure, system damage or
personal injury.
• This product is intended for use by qualified personnel
having the appropriate knowledge and skills like trained
according to EN 13313 or a specific training for
flammable refrigerants.
• Flammable refrigerants require special handling and
care due to its flammability. Sufficient ventilation is
required during service of the system. Contact with
rapidly expanding gases can cause frostbite and eye
damage. Proper protective equipment (gloves, eye
protection, etc.) has to be used.
• Ensure that the system is correctly labelled with applied
refrigerant type and a warning for explosion risk.
• In a severely contaminated system, avoid breathing acid
vapours and avoid contact with skin from contaminated
refrigerant / lubricants. Failure to do so could result in
injury.
• Before opening any system make sure pressure in
system is brought to and remains at atmospheric
pressure.
• Do not release any refrigerant into the atmosphere!
• Do not exceed the specified maximum ratings for
pressure and temperature.
• Do not use any other fluid media without prior approval
of EMERSON. Use of fluids not listed could result in:
- Change of hazard category of product and
consequently change of conformity assessment
requirement for product in accordance with European
Pressure Equipment Directive 2014/68/EU.
• Ensure that design, installation and operation comply
with European and national standards/regulations.
• For flammable refrigerants only use valves and
accessories approved for it!
M o u n t i n g l o c a t i o n :
• MIA...-FLR has to be installed only in the liquid line,
otherwise the humidity reading can show wrong values.
• MIA...-FLR 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 expansion valve.
I n s t a l l a t i o n :
• Do not remove seal caps until ready for installation in
order to minimize entering of moisture and dirt.
• WARNING: Avoid damaging the connections!
• The MIA...-FLR is fully hermetic and cannot be
disassembled.

• Perform the brazing joint as per EN 14324.
• Before and after brazing clean tubing and brazing joints.
• Minimize vibrations in the piping lines by appropriate
solutions.
• To avoid oxidization, it is advised to purge the system
with an inert gas such as nitrogen while brazing.
• Do not exceed the max. surface temperature of
100 °C!
• To avoid overheating it is advised to make the joint at one
end cool the device completely before repeating the
procedure on the other end connection.

P r e s s u r e T e s t :
After completion of installation, a pressure test must be
carried out as follows:
- according to EN 378 for systems which must comply with
European pressure equipment directive 2014/68/EU.
- Max. system test pressure: 38.5 bar
T i g h t n e s s T e s t :
Conduct a tightness test according to EN 378-2 with
appropriate equipment and method to identify leakages
from joints and products. The allowable leakage rate must
be according system manufacturer's specification.
WARNING:
• Failure to pressure test or tightness test as
described could result in loss of refrigerant, damage
to property and/or personal injury.
• The tests must be conducted by skilled personnel
with due respect regarding the danger related to
pressure.
H u m i d i t y R e a d i n g : ( F i g . 2 )
• 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.

S e r v i c e / M a i n t e n a n c e :
• Defective MIA...-FLR must be replaced, they cannot be
repaired.
• Disconnect electrical power before service.
• Before any debrazing ensure that the flammable
refrigerant is pumped out of the system and the room
around the system is well vented so no refrigerant left.
• According to EN 378-4
maintenance, tightness tests shall be carried out at the
relevant part of the refrigerating system. This shall apply
where appropriate following any repair.
