Emerson ALCO CONTROLS 110RB FLR Series Operating Instructions Manual

G e n e r a l i n f o r m a t i o n :
110RB- / 200RB-...FLR solenoid valves are used for open
or close of refrigerant flow.
The listed products are not in scope of ATEX product
directive 2014/34/EU as they do not incorporate an own
source of ignition.
110RB- / 200RB-...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 labeled with applied
refrigerant type and a warning for explosion risk.
• In a severely contaminated system, avoid breathing acid
vapors 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.
• WARNING: Do not use a solenoid valve as a safety shut-
off valve or for service purpose.
• Ensure that the system piping is grounded.
• Observe and avoid mechanical damage of component
housing.
• 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 :
• 110RB- / 200RB-...FLR should be installed as close as
possible to the device to be shut-off/controlled by the
valve.
• Allow sufficient clearance above the valve for removal of
coil. (see dimensions)
• Valves may be mounted in horizontal or vertical lines
(Fig. 1). Up-side down position is not allowed and can
cause mal-function.

I n s t a l l a t i o n :
• Do not dent, bend, or use the enclosing tube as a lever.
A damaged enclosing tube may result in coil burnout,
inoperative valve or leakage.
• Direction of flow must match arrow on body.
• Internal parts must be protected from foreign material and
moisture. EMERSON filter-drier use in liquid and suction
line is recommended.

B r a z i n g :
• Perform the brazing joint as per EN 14324.
• Do not disassemble valve before brazing.
• Before and after brazing clean tubing and brazing joints.
• To avoid oxidization, it is advised to purge the system with
an inert gas such as
nitrogen while
brazing.
• Never use oxygen
or flammable gases.
• Do not exceed
the max. surface
temperature of
120° C!
• Remove the coil by pulling it from valve prior to brazing.
I n s t a l l a t i o n C o i l :
• Observe coil compatibility. See technical data.
• For mounting of the coil please refer to coil operating
instruction.
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
2014/68/EU.
- to maximum system test pressure
110RB- / 200RB...FLR
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.
T e s t :
WARNING:
• EMERSON solenoid valves are equipped with a
continuous-duty coil, which when energized for an
extended period of time becomes hot. This is normal.
• Before Testing let the parts cool down to a temperature
< 40°C.
• Cycle valve several times. A distinct click should be heard
each time the solenoid is energized.

WARNING:
• Defective 110RB- / 200RB-...FLR must be replaced,
they cannot be repaired. Do not use reassembled
valve. Reassembled valve might not be leakage free.
• Never remove energized coil from valve. This applies
also for testing purposes.
• Before any service disconnect electrical power of the coil
and use permanent magnet to keep the valve open while
emptying the system.
• 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 during
maintenance, tightness tests shall be carried out at the
relevant part of the refrigerating system. This shall apply
where appropriate following any repair.
