1 – Introduction
These instructions pertain to Opty-
ma
™
Plus condensing units OP-MPYM,
OP-MPXM, OP-MPGM, OP-LPQM, OP-LPOM & OP-
MPBM used for refrigeration systems. They pro-
vide necessary information regarding safety and
proper usage of this product.
The condensing unit includes following:
• Microchannel heat exchanger
• Reciprocating or scroll compressor
• Receiver with stop valve
• Ball valves
• Sight glass
• High & low pressure switches
• Replaceable filter drier
• Electronic controller
• Main circuit breaker (Main switch with overload
protection)
• Fan and compressor capacitors
• Compressor contactor
• Supply monitoring relay**
• Robust weather proof housing
• Liquid injection controller (Module B Plus)*
• Electronic expansion valve (ETS6)*
*Only for P02 version,
**only for P05 models
2 – Handling and storage
• It is recommended not to open the packaging
before the unit is at the final place for installa-
tion.
• Handle the unit with care. The packaging al-
lows for the use of a forklift or pallet jack. Use
appropriate and safe lifting equipment..
• Store and transport the unit in an upright posi-
tion.
• Store the unit between -35°C and 50°C.
• Don’t expose the packaging to rain or corrosive
atmosphere.
• After unpacking, check that the unit is com-
plete and undamaged.
3 – Installation precautions
Never place the unit in a flammable atmos-
phere.
Place the unit in such a way that it is not bloc-
king or hindering walking areas, doors, windows
or similar.
• Ensure adequate space around the unit for air
circulation and to open doors. Refer to picture
1 for minimal values of distance to walls.
• Avoid installing the unit in locations which are
daily exposed to direct sunshine for longer pe-
riods.
• Avoid installing the unit in aggressive and dus-
ty environments.
• Ensure a foundation with horizontal surface
(less than 3° slope), strong and stable enough
to carry the entire unit weight and to eliminate
vibrations and interference.
• The unit ambient temperature may not exceed
50°C during off-cycle.
• Ensure that the power supply corresponds to
the unit characteristics (see nameplate).
• When installing units for HFC refrigerants, use
equipment specifically reserved for HFC refri-
gerants which was never used for CFC or HCFC
refrigerants.
• Use clean and dehydrated refrigeration-grade
copper tubes and silver alloy brazing material.
• Use clean and dehydrated system components.
• The suction piping connected to the compres-
sor must be flexible in 3 dimensions to dampen
vibrations. Furthermore piping has to be done
in such a way that oil return for the compres-
sor is ensured and the risk of liquid slug over in
compressor is eliminated.
4 – Installation
• The installation in which the condensing unit is
installed must comply to pressure Equipment
Directive (PED) 2014/68/EU. The condensing unit
