Optyma™ Slim Pack
OP-LSQM / LSHM / MSXM /
MSHM / MSGM / MSBM
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 & II models: Pressure relief valve shall be mounted in refrigerant system during field installation. PRV should be mounted on receiver vessel.

1 – Introduction
These instructions pertain to Optyma
Pack condensing units OP-LSHM/MSHM/MSGM/
LSQM/MSXM/MSBM (R448A, R449A, R452A,
R407A, R407F, R507, R404A, R134a, R513A) used
for refrigeration systems. They provide necessary
information regarding safety and proper usage
of this product.
The condensing unit includes following:
• Scroll/reciprocating compressor
• Microchannel heat exchanger
• Dual pressure switches
• Service valves Suction/ liquid
• Weather proof housing
• Filter drier
• Cranckcase heater for compressor
• Receiver with stop valve
• Sight glass
• Phase sequence relay (scroll compressors)
• Fully pre-wired electrical panel (including main
switch, compressors contactor, overload relay)
• Fan speed controller and External main switch
(W09 only)
• Components connected are equipped with
Schrader port
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 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 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 com-
plete and undamaged.

3 – Installation precautions
TM Slim
Do not braze as long the condensing
unit is under pressure.
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 & 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 picture1
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 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 or HFO refrige-
rants, use equipment specifically reserved for
HFC or HFO refrigerants 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.
• In Optyma condensing unit has suction and
liquid service valve with schrader port for field
service operation
3.1 – PRV Valve
For Optyma™ Slim Pack, Condensing
units which are fall in PED cat I & 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 )
• Installer need to take care of where to blow the
leaked refrigerant. Danfoss recommended to
blow refrigerant away form condensing unit.
• Recommended to change PRV when after
discharge, Changing refrigerant
• Valves must be installed
Horizontally, but ensure PRV to be fitted above
system's liquid level.
