Introduction
Many end-users, equipment and compressor manufacturers are investigating ways to minimize their impact on the
environment. Improving system architectures, using a refrigerant with lower global warming potential (GWP) can
significantly improve the carbon footprint of an installation. R290 is one of the most-discussed refrigerants which has long
been known for its good performance as refrigerant but is flammable and consequently brings about strict considerations
for system manufacturers in terms of system design and operation. The specified listed products in this section have been
released for use in systems using R290 as a refrigerant by considering information related to each product as follows:

Technical Bulletin
ZH Copeland Scroll™ for R290 (Propane)
Propane (R290) is a flammable natural refrigerant which has long been
known for its good performances. It has zero ozone depletion potential,
negligible global warming potential, as well as excellent thermodynamic
properties. R290 systems require in average half the charge of
hydrofluorocarbons (HFCs). These features make R290 suitable for
upcoming F-gas regulations. Emerson is launching a full line-up of
propane Copeland Scroll compressors designed for chillers and heat
pump applications. This line-up meets Emerson reliability standards and
is classified ATEX Group II.

ZB Copeland Scroll™ for R290 (Propane)
Technical Bulletin
Emerson Climate Technologies is offering a full range of propane Copeland
Scroll compressors. The new ZB*KCU Copeland Scroll compressor range
with R290 is the ideal choice for self-contained medium-temperature
applications. These compressors are also suitable for refrigeration chiller
and small cascade systems. The complete compressor range of propane
scrolls meets Emerson´s reliability standards and is ATEX Group II
classified.
Propane (R290) is a flammable natural refrigerant which has long been
known for its good performance. It has zero ozone depletion potential,
negligible global warming potential (GWP), as well as excellent
thermodynamic properties. R290 systems require in average half the
charge of hydro-fluorocarbons (HFCs). These features make R290
suitable for the upcoming F-gas regulations.

Operating Instructions
General Information
Mounting Location
EX4-7…-FLR are stepper motor driven valves for precise
control of refrigerant mass flow, released for R290 in
refrigeration, air conditioning, heat pumps, industrial cooling
process and close control systems.
• The motor needs to be pointed downward or sideways
(Fig. 1).
• For best result, locate the valve as close as possible to the
distributor or inlet of evaporator.
Warning
The qualification /certification of EX4-7-…FLR is valid only in
conjunction with EVC05A (Plug & Cable assembly).
The listed products are electrical devices and are in
compliance with EN60079-0/-15 and directive 94/9/EC
therefore rated / marked as:
II 3G Ex nA IIA T3 Gc X
Safety Instructions
• 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.
• R290 requires special handling and care due to its
flammability. Good 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.
• 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.
• Ensure that the system is correctly labeled with applied
refrigerant type and a warning for explosion risk.
• 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!
• Ensure that the system piping is grounded.
• Do not exceed the specified maximum ratings for
pressure, temperature, voltage and current.
• Do not operate valve connected directly to supply
voltage. Use suitable stepper motor driver.
• Do not operate system before all cable connections
are completed.
• Do not operate the valve when the compressor is not
running.
• Do not operate the valve when system is under vacuum
except for closure of valve before refrigerant charging.
• Before installation or service disconnect all voltages
from system and device.
• Do not use any other fluid media without prior
approval of Emerson.
• Ensure that design, installation and operation are
according to European and national standards/
regulations.
Installation
• Direction of refrigerant flow must match with arrow
on the label (except bi-flow valves).
• Check for sufficient refrigerant charge/subcooling and
make sure no flash gas is present at the inlet of valve
before attempting to check valve operation.
• Install an Emerson sight glass MIA…-FLR and an
ADK….-FLR filter before the valve.
Warning
• All valves are delivered at half open. Do not charge
system before closure of valve. See operating
instructions of used driver/controller.
• The interior parts of valve must be protected against
moisture and water at any time. It is not permitted
to use water, steam or any other solvent to the inside
of valve for cleaning purpose.

Operating Instructions
Electronic Expansion Valves EX4-7-…FLR Versions
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.
Tightness Test
• 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 according system manufacturer’s specification.
Electrical Connection:
Warning
• Entire electrical connections have to comply with
local regulations.
• Improper wiring will result wrong direction of
rotation, no rotation of stepper motor or controller
malfunction.
Wiring / Mounting of Plug: (Fig. 4-6)
• 2 = White, 4 = Black, 3 = Blue, 1= Brown
• Use only ATEX approved prewired M12 Connector
assembly EVC05A for connection to the valve.
• See also EVC05A operating instructions for plug
mounting and required protection.
• There is no specific requirement for positioning of plug
on pins (see Fig. 5).
• Ensure that the cables are mounted without
tension; always leave the cable a bit loose.
• Ensure that cables are not mounted near sharp edges.
• Do not bend or mechanically stress the cable outlet,
maintain a clearance of 20 mm to neighboring parts.
• During operation the connector EVC05A must
be protected by an appropriate housing against
external mechanical damage or shock (min. required
protection up to a mechanical action of 7 J - in
accordance with EN60079-0).
• Cable end of EVC05A must be connected to a driver/
controller which is ATEX approved or located out of
hazard zone.
- If driver/controller is located out of hazard zone,
appropriate ATEX approved cable gland shall
be used in boundary of hazard zone and out of
hazard zone.
- If the cable needs to be extended in hazard zone, it
is mandatory to use ATEX approved type coupling
or junction box.
• Supply voltage to the valve shall never exceed 36
VDC at any time.
Service / Maintenance
• Defective EX4-7-…FLR valves must be replaced, they
cannot be repaired.
• Disconnect electrical power to driver/controller
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.
• For motor check:
- Remove cable plug from valve under no voltage.
- Use an Ohm meter with suitable range.
- Measure windings resistance per phase at opposite
placed pins acc. Fig. 6 and data as in the table below.
• The lowest pressure inside system must be at least
0.4 bar higher than ambient pressure at any time.
Failure to do so could accumulate air inside the
system and create an explosive mixture over time.

Operating Instructions
ThermoTM - Expansion Valves TX3-…FLR
General Information
TX3-…FLR are Thermo-Expansion Valves for superheat control.
Fig. 1
The listed products are not in scope of ATEX product directive
94/9/EC as they do not incorporate an own source of ignition.
TX3-…FLR must be installed in an appropriate housing to
protect them from mechanical damage or shock.
Safety Instructions
• 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.
• R290 requires 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.
• 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.
• Ensure that the system is correctly labeled with
applied refrigerant type and a warning for explosion risk.
• Do not release any refrigerant into the atmosphere!
• Do not exceed the specified maximum ratings for
pressure and temperature.
• Before opening any system make sure pressure in
system is brought to and remains at atmospheric
pressure.
• Observe and avoid mechanical damage of
component housing.
• Ensure that design, installation and operation are
according to European and national standards/
regulations.
Installation (Fig. 1, 2)
• Valves may be installed in any position, but should
be located as close as possible to the distributor or
evaporator inlet.
• Attach the remote bulb to the suction line (Fig. 2) as
close to the evaporator outlet as possible. Securely
fasten the bulb with straps provided. Insulate bulb
with a suitable material. Ensure that the capillary is
mounted without tension, always leave the capillary
a bit loose and it should not be strangulated. Maintain
also a clearance from the capillary to other objects. The
capillary should not be in contact with other objects.
22
Fig. 2
<7/8” / 22 mm Ø
• Connect equalizer line (1/4” or 6 mm tube) to valve and
suction line. Be sure that it cannot siphon oil from the
suction line (Fig. 1).
• The expansion valve must be free of all contaminants.
Install an Emerson filter drier before the valve.

Operating Instructions
ThermoTM - Expansion Valves TX3-…FLR
Brazing (Fig. 3)
Superheat Adjustment (Fig. 4)
• Perform and consider the brazing joint as per EN 14324.
• 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.
TX3-…FLR are factory set to a standard setting (s. Technical
Bulletin). If the superheat must be adjusted proceed as
follows:
1. Remove seal cap from bottom of valve.
2. Turn adjustment screw clockwise to increase and
counterclockwise to decrease superheat.
Do not exceed max. body temperature of 120°C!
Fig. 3
120°C
max
Warning: There are approx. 13 turns on the
adjustment stem (from left to right stop). When
stop is reached any further turning will damage
valve. Changes in superheat (K) per stem turn
depending on evaporating temperature and refrigerant;
see below. 30 minutes are required for the system to
stabilize after the adjustment is made.
Superheat change (K) per stem turn
• Be sure liquid line is connected to inlet of TX3-…
FLR (marked “IN” on valve body).
• Minimize vibrations in the piping lines by appropriate
solutions.
Pressure Test
• After completion of installation, a pressure test must
be carried out according to EN 378 for systems which
must comply with European pressure equipment
directive 97/23/EC.
• Max. system test pressure: 38.5 bar.
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.

Service / Maintenance
max. 120°C
• Defective 200RB…-FLR must be replaced; they cannot
be repaired.
• 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.
• Warning: Never remove energized coil from valve.
This applies also for testing purposes.
Technical Data of 200RB... -FLR
• Internal parts must be protected from foreign material
and moisture. An Emerson filter drier is recommended
to be installed.
• Minimize vibrations in the piping lines by appropriate
solutions.
Pressure Test
• After completion of installation, a pressure test must
be carried out according to EN 378 for systems which
must comply with European pressure equipment
directive 97/23/EC.
• Max. system test pressure: 34.1 bar.
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.
Tightness Test
Conduct tightness test according to EN 378-2 with
appropriate equipment and method to identify
tightness of external joint. The allowable leakage rate must
be according system manufacturer’s specification.
Operation
• Before operation let the parts cool down to a
temperature < 40°C.
• Cycle valve several times. A distinct “click” should be
heard each time the solenoid coil is energized.
Note: Emerson solenoid valves are equipped with
a continuous-duty coil, which when energized for an
extended period of time becomes hot. This is normal.

Operating Instructions
Hermetic Liquid Line Filter Driers ADK-…FLR
General Information
ADK-…FLR filter driers are used for protection of systems
against contaminant.
The listed products are not in scope of ATEX product directive
94/9/EC as they do not incorporate an own source of ignition.
ADK-…FLR must be installed in an appropriate housing to
protect them from mechanical damage or shock.
Safety Instructions
• Read operating instructions thoroughly. Nonobservance 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.
• R290 requires 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.
• In a severely contaminated system, avoid breathing
acid vapors and avoid contact with the skin from
contaminated refrigerant/lubricants. Failure to do
so could result in injury.
• Ensure that the system is correctly labeled with applied
refrigerant type and a warning for explosion risk.
• Do not release any refrigerant into the atmosphere.
• Do not exceed the specified maximum ratings for
pressure and temperature.
• Before opening any system make sure pressure in
system is brought to and remains at atmospheric
pressure.
• Do not use on any other fluid media without prior
approval of Emerson. Use of fluids not listed could
result in chemical deterioration of the desiccant in
filter drier.
• Ensure that design, installation and operation are
according to European and national standards/
regulations.
Mounting Location
• Filter driers may be installed in any position within
the liquid line. Direction of refrigerant flow must be
observed.
38
• For best results locate the filter drier as close as possible
to the inlet of expansion device. If using a liquid line
solenoid valve and/or moisture indicator.
Locating
filter drier upstream will provide protection for the
solenoid valve and the moisture indicator will measure
the effectiveness of the drier.
• Protect the filter drier against sunrays and vibration.
Installation
• Do not remove seal caps until ready for installation in
order to minimize entering of moisture and dirt.
Avoid damaging the connections!
• Direction of refrigerant flow must match with arrow
on the label. Reverse flow reduces the filtering ability
and increases the pressure drop through the filter drier.

of external joints. The allowable leakage rate must be
according system manufacturer’s specification.
Operation
• After leakage test start system and after sufficient
running time check color of moisture indicator for
moisture level. We recommend the use of Emerson
moisture indicators.
• In systems with excessive moisture it may be necessary
to replace the filter drier for several times in order to
bring moisture in the system to a safe level.
Service / Maintenance
• 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.
• Disconnect electrical power before service.
• Always install a new filter drier when existing
ones become saturated with moisture and foreign
materials.
• Do not attempt to dry out a used filter drier.
