Emerson OM3 Instrucciones De Funcionamiento

G e n e r a l i n f o r m a t i o n :
All versions use a Hall-Sensor to measure the oil level. A magnetic float changes
its position according to the oil level. The hall sensor converts these magnetic
field changes into an equivalent signal, which is used by the internal electronic
to show the actual oil level with LED's and activate the integrated solenoid valve
to feed missing oil directly into the compressor sump. For application in
refrigeration systems according to EN 378.
Notes:
OM3... is the well-proven solution for HFC and specified HFO blends
refrigerants.
OM4... is developed for HFC refrigerants, subcritical CO
HFO blends.
OM5... is specially adapted to the requirements of transcritical CO
and has to be used with dedicated types of CO
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.
• 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 exceed the specified maximum ratings for pressure, temperature,
voltage and current.
• Before installation or service disconnect all voltages from system and
device.
Note: Float contains lead and has to be recycled in case of disposal!
