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
