NOTE 1: MOPD will decrease if the coils will be used at 60 Hz frequency. Also follow the operating instructions of the used devices.
ESC-EX... 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. 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.) must be used.
• Ensure that the system is correctly labeled with applied refrigerant type and a warning
for explosion risk.
• The coil should be fused in accordance with local codes. Electrically ground the valve
body.
• Do not exceed the specified maximum ratings for pressure, temperature, voltage and
current.
• Ensure that the system piping is grounded.
• Before installation or service disconnect all voltages from system and device.
• Observe and avoid mechanical damage of component housing.
• Do not energize coil unless it is attached to the device.
• 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.
• Disposal: Electrical and electronic waste must NOT be disposed of with other
commercial waste. Instead, it is the user responsibility to pass it to a designated
collection point for the safe recycling of Waste Electrical and Electronic Equipment
(WEEE directive 2012/19/EU). For further information, contact your local environmental
recycling center.

• Mount O-ring with smaller diameter (1) over enclosing tube.
• Place coil over the enclosing tube and press it down by hand.
• Place the black retainer (2) on the upper visible end of the enclosing tube. The two slots
of the retainer fit to stumps of ESC-EX... coil. (5)
• Insert O-ring with larger diameter (3) inside of the orange screw cap
• Press coil well down and tight the screw cap (4) over the retainer firsthand tight and then
with torque 0.5 - 0.6 Nm in order to provide IP65 protection. Use spanner size 27 mm.

E l e c t r i c a l c o n n e c t i o n :
• Entire electrical connections have to comply with local regulations.
• Before energizing the device, be sure that the source voltage and frequency matches
that on the coil label.
• 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.
• Make sure a fuse installed ahead of coil at appropriate location (non ATEX environment
or explosive protective switch box).
• Molded plug and cable assembly:
Brown and blue color wires to be connected to the power supply and yellow/green color
wire to the ground.
S e r v i c e / M a i n t e n a n c e :
• WARNING: ESC-EX... coils are intended for continuous-duty, which when
energized for an extended period of time, it becomes hot. This is normal. Do not
touch the coil during operation. Wait for coil temperature to cool down before
attempting to dissemble it, or use gloves, failure to do so could lead to injury.
• Disconnect electrical power before service.
• Dismantle of ESC-EX: unscrew the screw cap (4) and pull the coil with retainer (2) out.
Remove smaller O-ring.
• Replacement of ASC...+PG9 plug/ ASC3-EX... with ESC-EX... series:
- Dismantle ASC... by opening blue clip (Fig.2)
- Dismantle ASC3-EX...: see Fig. 3. Remove smaller O-ring.
- To ensure proper function and protection, only O-rings approved for ESC coils may be
used. Any existing O-rings must be replaced.
