Emerson Alco Controls 110RB Instructions De Service

G e n e r a l i n f o r ma t i o n :
110RB/200RB/200RH/240RA Solenoid Valves are
used for shut-off purpose during operation on liquid,
suction and discharge line. Valve except 540RA are
normally closed types (NC), means when coil is de-
energized valve is in closed position. 540RA is
normally open type (NO).
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.
• According to EN 13313 it is intended for use by
persons having the appropriate knowledge and
skill.
• Before opening any system make sure pressure
in system is brought to and remains at
atmospheric pressure.
• 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.
• 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.
• 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
accordance with European pressure equipment
directive 97/23/EC.
M o u n t i n g l o c a t i o n :
• 110RB/200RB/200RH/240RA 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.
• 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 line and EMERSON filter use in suction line
is recommended.

B r a z i n g : ( s e e F i g . 2 )
• Perform and consider the brazing joint as per
EN 14324.
• Do not disassemble valve before brazing.
• Before and after brazing clean tubing and brazing
joints.
• The use of appropriate brazing material is required
(soft solder is not allowed).
• 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. body temperature of
120°C!
C o i l C o mp a t i b i l i t y :
• EMERSON solenoid valves are released to be used
with following coils:
– ASC3 - compatible with 110RB, 200RB,
200RH, 240RA & 540RA,
• For more information see ASC3 coil operating
instructions.
T e s t i n g :
• 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.
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 97/23/EC.
for product in
– to maximum working pressure of system for other
applications.
Warning:
• Failure to do so could result in loss of refrigerant
and personal injury.
• The pressure test must be conducted by skilled
persons with due respect regarding the danger
related to pressure.
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 of external joints. The allowable leakage rate
must be
specification.
S e r v i c e / M a i n t e n a n c e :
• Before any service shut down system and
disconnect from power source.
• Fully depressurize Valve. After reducing pressure to
atmospheric the valve may be opened and internal
parts removed and replaced. Clean parts before re-
installation. Install parts in reverse sequence as
removed (Fig. 3).
