Optyma™ Slim Pack
OP-LSVM, MSTM, MSSM and MSIM
Optyma™ Slim Pack electrical box ingress protection level is IP54 to avoid quick A2L refrigerant migration. Sealing needs to be maintained and any
damage on sealing needs to be repaired appropriately. (See section 8 - Safety)
E-Box door must always be closed during operation and after service/periodic maintenance.
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 and according to instruction. 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 (2 bar(gauge) 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°)
Condensing units can be used with A2L refrigerants, necessary care to be taken during installation and servicing.
In case of A2L refrigerants, all components on the refrigeration circuit must be A2L certified. Example: Evaporator.
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
condensing units OP-LSVM, MSTM, MSSM and
MSIM (R448A, R449A, R452A, R407A, R407F, R507,
R404A, R134a, R513A, R1234yf, R454C & R455A)
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 with schrader Valve
• AC Fan motor for B1 & B2, EC Fan motor for B3
units
• Weather proof housing
• Filter drier (Flare connections)
• Cranckcase heater for compressor
• Receiver with stop valve
• Sight glass (Flare connections)
• IP54 fully pre-wired electrical panel (including
compressors contactor, overload relay, timer)
• Fans speed controller*
• Main switch with extended Rotary handle**
• Components connected are equipped with
Schrader port
* Factory pre-mounted for W09, not factory pre-
mounted for W05.
** Only for W09
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
allows for the use of a forklift or pallet jack. Use
appropriate and safe lifting equipment.
2 | AN37261865152501-010301 - 118A2176C
• Store and transport the unit in an upright position.
Slim Pack • Store the unit between -35°C and 50°C.
TM
• Don't expose the packaging to rain or corrosive
atmosphere.
• After unpacking, check that the unit is complete
and undamaged.
3 – Installation precautions
Do not braze as long as the condensing
unit is under pressure.
It's not allowed to operate the unit in
flammable atmosphere.
Place the unit in such a way that it is
not blocking or hindering walking
areas, doors, windows or similar.
A2L refrigerants are heavier than air.
Unit has to be installed above floor
level to have a good compressor
compartement ventilation.
PRV: For PED Cat I & II models, PRV shall
be mounted at field during installation.
• Ensure adequate space around and below the
unit for proper air circulation and to open doors.
Refer to Annex - A, Picture 1 for minimum distance
to walls and ground.
• 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 shall not exceed
50°C during off-cycle.
• Ensure that the power supply corresponds to the
unit characteristics (See nameplate in unit).
• When installing units for R454C, R455A & R1234yf
refrigerants, use equipment specifically reserved
for mildly flammable refrigerant which was never
used for other CFC, HFO 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 (Not factory fitted)
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 used as damage limiting device,
not as pressure limiting device.
• 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 )
