Instructions (English)
Optyma Plus
™
OP-LPQM, OP-MPYM, OP-MPXM,
OP-MPGM, OP-LPOM
Installation and servicing of the condensing units by qualified personnel only. Follow these instructions and sound refrigeration engineering practice
relating to installation, commissioning, maintenance and service.
The condensing unit must only be used for its designed purpose(s) and within its scope of application. Refrigerant to be used as per specification with respect to
model.
Under all circumstances, the EN378 (or other applicable local safety regulation) requirements must be fulfilled.
The condensing unit is delivered under nitrogen gas pressure (1 bar) and hence it cannot be connected as it is; refer to the «installation» section for further
details.
The condensing unit must be handled with caution in the vertical position (maximum offset from the vertical : 15°)
For PED Cat I and II models: Pressure relief valve shall be mounted in refrigerant system during field installation. PRV should be mounted on receiver vessel.

• Electronic expansion valve (ETS6)*
• Components connected are equipped with
Schrader port
*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 installation.

• Handle the unit with care. The packaging
to Optyma ™ allows for the use of a forklift or pallet jack. Use
OP-MPYM, appropriate and safe lifting equipment..
• Store and transport the unit in an upright
position.
• 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 complete
and undamaged.
3 – Installation precautions
Never place the unit in a flammable
atmosphere.
Place the unit in such a way that it
is not blocking or hindering walking
areas, doors, windows or similar.
PRV: For PED Cat I and II models, PRV
shall be mounted at field during
installation.
• 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
periods.
• Avoid installing the unit in aggressive and dusty
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
refrigerants which was never used for CFC or
HCFC refrigerants.
• Use clean and dehydrated refrigeration-grade
Copper / Aluminium tubes with appropriate
thickness and silver alloy brazing material.
• Use clean and dehydrated system components.
• The suction piping connected to the compressor
must be flexible in 3 dimensions to dampen
vibrations. Furthermore piping has to be done
in such a way that oil return for the compressor
is ensured and the risk of liquid slug over in
compressor is eliminated.
• In Optyma condensing unit has suction and liquid
service valve with schrader port for field service
operation
3.1 – PRV Valve
For Optyma™ Plus, Condensing units
which are fall in PED cat I and II, PRV
shall be fitted (See Technical data for
PED category in Annex A).
PRV is provided as Spare part,. Refer
Coolselector2
• PRV to be fitted on liquid receiver at 3/8" NPT
Connection. (Refer Coolselector2 for PRV spare
part code). Use Locatite 554 for PRV fitment.
• Torque: 40Nm (Don't exceed given torque )
