Instructions
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.
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.
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 mildly flammable 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.

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
• 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**
* 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
2 | AN37261865152501-010201 - 118A2176B
allows for the use of a forklift or pallet jack. Use
Slim Pack
appropriate and safe lifting equipment.
TM
• 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
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.
• 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
which was never used for CFC, HFO or HCFC
refrigerants.
• Use clean and dehydrated refrigeration-grade
copper 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.
4 – Installation
• Installation/servicing of Optyma™ Slim Pack
condensing units must be carried out by
qualified personnel with respect to applicable
local/international regulation.
• The installation in which the condensing unit is
installed must comply to EC Pressure directive
