NOTE 1: MOPD will decrease if the coils will be used at 60 Hz frequency. Also follow the operating instructions of the used devices.
NOTE 2: 1) OM3-02P used with R290 (A3). Installation only in a non-explosive environment.
NOTE 3: 2) Temperature impacts MOPD and coil use. Please refer to Technical Information of the connected valve.
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.
• The coil should be fused in accordance with local codes. Electrically ground the valve
body.
• Do not exceed the specified maximum ratings for 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.
• 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 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.
• Ensure, that the plug (with cable) is correctly placed and tighten.

Standard plug and cable assembly (ASC-N...)
Brown and blue color wires (BN & BL Fig. 2) to be connected to the power supply and
yellow/green color wire to the ground. Connect pre-wired plug to the coil and tighten
screw with 0.2 Nm.
•
Wiring with DIN Plug (Fig. 3)
Cable with three wires has to be connected to terminal 1 and 2 and
plug terminal box. Connect pre-wired DIN-plug to the coil and tighten screw with 0.2 Nm.
S e r v i c e / M a i n t e n a n c e :
• WARNING: ESC 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: unscrew the screw cap (4) and pull the coil with retainer (2) out.
Remove smaller O-ring.
•
Replacement of ASC.../ ASC3... with ESC series:
-
Dismantle ASC... by opening blue clip (Fig.4)
-
Dismantle ASC3...: see Fig. 5. 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.
